• Driver note: Panther/PT LE 6.2.3 retained AMIII code but Digidesign did not qualify it.
• Released at AES Copenhagen.
• Audio: 2×2 analog·18-bit AD/DA·11.025–48 kHz·24-bit coax S/PDIF·7".
• Converters, photo-confirmed: CS5330A-KS ADC (9638;1996 W38;overview year='96)·CS4331-KS DAC (9639;1996 W39;overview year='95). Oct '97 CDB5330A/CDB5331A documentation is later evidence,not the CS5330A introduction date.

• Physical family: full-length PCI board silkscreened “digidesign PROJECT / DISK I/O PCI”. Project and Disk I/O share the base PCB family, but they are different ROM/system configurations;the PCB revision and the fitted controller/chip revision must be tracked separately.
• Photographed Project specimen: ASY 915003867-02·FAB 941003867-01 REV C·©1996·serial FE01196·single 5V PCI key·32-bit conventional PCI edge·full-length. The small handwritten role code beside the assembly marking is “02”;Digidesign/Sweetwater identifies “01”=Disk I/O and “02”=Project.
• PCI/controller: photographed controller=AMCC S5933Q. It is the earlier Q device,not the S5933QC-or-newer revision Digidesign requires for PCI-2.1/B&W-G3/G4 compatibility. Therefore the card itself must not be labelled PCI 2.1 merely from the S5933 family name. The S5933 architecture is 32-bit/33 MHz and supports PCI bus-master DMA, but use of that bus-master facility by Digidesign on this card is not established→overview BM remains ?.
• SCSI: Symbios/NCR 53C710 SCSI I/O processor·8-bit Fast-SCSI·up to 10 MB/s synchronous on the SCSI side·on-chip SCRIPTS processor. Its local DMA capability does not by itself prove PCI bus mastering by the Digidesign card.
• DSP: Motorola DSP56002FC66·24-bit fixed-point DSP·66-MHz speed grade·up to 33 MIPS·56-bit accumulators. “24-bit DSP” describes internal DSP architecture and must not be used as evidence of 24-bit recording/conversion.
• Memory fitted on the photographed board: 2 MiB DRAM + 512 KiB SRAM. DRAM=4× NEC 424400. SRAM=3× Samsung KM681002J-15 + 4× Motorola MCM6206BAEJ15. Exact assignment of the individual memory banks/functions remains unresolved.
• Further logic: QuickLogic QL12X16B-0PF100C (100-pin package)+QL8X12B-2PL44C·Digidesign ELVIS ASIC·Digidesign TDM ASIC·Altera device with type obscured by label. Oscillators: 66/60/30 MHz.
• Connections: VHDCI50→SCSI storage;60-pin Digidesign peripheral connector→audio interface/DSP-system path. The 60-pin peripheral connector is not SCSI storage.
• Converters: — on the PCI card. A/D and D/A conversion resides in the attached Digidesign 882/888-family interface.
• Project ≠ Disk I/O: Project and PT III/Disk I/O are not made equivalent by the presence of the shared TDM connector. Project is the 8-voice/8-track configuration;Pro Tools III with Disk I/O provides 16 voices. System/ROM configuration determines the role.
• Software identity: Project Audio Card·8-track·882/888 I/O;PT 3.4 identifies Project separately;PT 4.0 documents PCI/NuBus Project as 8-channel direct-to-disk.
• Driver note: Project DATa 3.1 uses DigiSystem INIT 3.01+;Disk I/O OS 9.1 untested;Pro Tools 5.1+ drops Pro Tools III core hardware.
• Timeline: Pro Tools III PCI announced 1996-05-11→Disk I/O shipping 1996-06;Pro Tools Project PCI shipping/documented later in 1996.

Sources:compatDigidesign SAMPLECELL II ™ PCI 1996-11-22

• PCI generations: early photographed production hardware carries AMCC S5933Q;later cards carry S5933QC+. Digidesign explicitly requires S5933QC or later for PCI 2.1 compatibility and for Blue & White G3/G4 operation;older group <HH02001/pre-Rev-D/pre-1997-05-20 uses the earlier AMCC revision.
• Photographed production examples: FAB 941004130 Rev C·ASSY 915004130·single 5V PCI key·full-length PCB. One supplied specimen shows AMCC S5933Q;another photographed Rev-C specimen shows S5933QC. S5933=32-bit/33 MHz PCI master/slave;FIFO DMA/bus-master transfers.
• D/A: four identical ~20-pin DAC ICs at U11/U21/U29/U34 serve the four stereo output pairs/8 analog outputs;package markings are unreadable in the available photos,so exact DAC type remains ?.
• Hardware visible in supplied card photos: Motorola DSP56002FC66;8×30-pin SIMM sockets;four stereo 1/4″ output jacks.
• Memory: 8/16/24/32 MB Mac-II-type 30-pin RAM.
• Optional TDM daughterboard photographed separately: silkscreen “SAMPLECELL II ™ TDM, PCI”·FAB 941004129 Rev A·Digidesign TDM ASIC;mounts to the SampleCell II PCI card rather than being a second sampler card.

• Revision: second-generation SampleCell II PCI;Digidesign describes the hardware difference as 32 MB RAM soldered on-board instead of user-installed SIMMs. All Plus cards are from the later PCI-compatible generation.
• PCI/form factor therefore follows the same S5933-based SampleCell II architecture: 32-bit/33 MHz·5V·BM·full-length;exact DAC IC remains ?.
• Mac: minimum 7.5.2;optional TDM module.

• Driver note: PARIS 3.0 is the last Mac-era release found;official OS X support remains ?.
• EDS-1000 hardware:
  • Six Ensoniq ESP-2 proprietary 24-bit DSPs on the complete EDS-1000 configuration.
  • Bus-master DMA;contemporary review material specifies up to 24 simultaneous digital data streams.
  • 20 inputs+20 outputs internally at 24-bit;any combination of 16 simultaneous record/playback tracks per card in the original system architecture.
  • Approx. 11.25 in/286 mm card length.
  • Surviving photographed production hardware is labelled E-MU/ENSONIQ·Model PARIS EDS1000·Part 3522;examples also carry an EDS-1000X sticker.
• EDS-500/EDS-FX relationship:
  • Later PARIS Concept systems used the EDS-500 PCI card with four ESP-2 DSPs.
  • The optional EDS-FX daughterboard plugs onto the EDS-500 and upgrades it to the EDS-1000-class DSP configuration.
  • Sweetwater's period PARIS Concept documentation explicitly describes EDS-500+EDS-FX as the path to the EDS-1000 configuration.
• Converters: — external. The EDS PCI card itself is the DSP/host card;A/D and D/A conversion resides in the external Interface 2/442/MEC hardware. Contemporary PARIS II specifications describe 20-bit A/D and D/A conversion at 44.1/48 kHz with a 24-bit internal audio path.
• Card expansion: PARIS supports multiple EDS cards. The reference manual documents internal card-to-card synchronization/interconnection and systems with up to eight EDS-1000 cards.
• EDS-1000 rear interfaces:
  • EDS Interface connector→Interface 442/MEC.
  • IF2 connector→Interface 2.
  • CS connector→Control 16.
  • The external interface connector uses SCSI-style hardware but is a proprietary PARIS connection;it must not be treated as a computer SCSI bus.
• Timeline:
  • 1997-07-17—archived PARIS interface material.
  • 1997-11—Ensoniq advertising documents the EDS-1000 PCI card with six 24-bit DSPs and Mac/PC operation.
  • 1998-01—detailed Sound On Sound PARIS II review;cross-platform PCI system.
  • 1998-05—Mix field test: EDS-1000 with six ESP-2 DSPs,installed in a PowerMac.

• P22 · Digi 001 OS X ceiling pass: PT LE 6.4 is final Digi001 Pro Tools release;official qualification centered on Panther 10.3.2/10.3.4. User reports beyond this are not substituted for official table bounds.
• P23 · Audiomedia III OS X pass: Digidesign/Avid administrator: PT LE 6.2.3 Panther retained AMIII code but was untested;last officially supported Mac OS X remains Jaguar-era 10.2.8. Existing distinction is correct.
• P24 · d24/PT24 OS X pass: PT|24 d24 officially supported through PT 6.1/Mac OS X 10.2.8;6.4.1/10.3.4 is MIX-only. Existing d24 10.2.3–10.2.8 ceiling retained.
• P25 · SW1000XG chronology pass: Yamaha Q2/98 FAQ explicitly says not yet Macintosh-compatible;later Mac guide requires OS 8.1 minimum and notes 8.6 for B&W machines. Existing overview 8.1–9 is supported;OS X driver was intended but never delivered.
• P26 · DS2416 chronology pass: early 1998 Mac driver still in development;by Apr 1999 period reporting says Mac drivers available. Final Yamaha Classic package=Driver 1.0.6 for Mac OS 9. Keep exact first supported numbered Mac OS floor ? pending original Mac driver readme.
• P27 · Yamaha converter cross-check: Yamaha comparative technical material identifies SW1000XG ADC=20-bit Burr-Brown PCM1800 and DAC=18-bit NEC;DS2416 ADC=20-bit Cirrus CS5335 and core-card DAC=20-bit. Existing exact DS2416 AK4321 identification remains photo/evidence-specific and should not be replaced by generic resolution prose.
• P28 · Alesis ADAT/PCR pass: product specification=5×4.25×0.75in standard PCI card·Mac PowerPC 300MHz 604e·OS 7.6.1·128MB·ASIO+Sound Manager;8-ch ADAT optical+9-pin ADAT sync;16/20/24-bit transfer. Exact PCI revision/clock/BM still ?.
• P29 · Sonorus period pass: May 1998 period ad explicitly=16-channel digital I/O for PC/Mac·24-bit·PCI·Mac Cubase VST driver. Later OS9 user evidence confirms continuation. No credible OS X driver found;user evidence says product ended before OS X and unusable there.
• P30 · Project II pass: late-1998 period material=half-size plug-and-play PCI·single 60-pin peripheral port·Macintosh+Windows NT·Direct I/O·16/24-bit depending on interface/software. Supports current canonical d24-family treatment but role remains distinct.
• P31 · Pro Tools chronology pass: Avid release history dates PT 3.21 PCI release 1996-05-14;PT4.1/d24 1997-09-24;PT4.3/MIX 1998-09-25. These are software/card-introduction anchors and should be kept distinct from first ship/review dates already used where stronger.
• P32 · SampleCell DAC attack: repeated searches for AD1868/CS4390/etc. produced no evidence-grade mapping to the four DAC packages on SampleCell II PCI. Digidesign only establishes eight outputs with individual D/A. Retain ? DAC.
• P33 · Gadget Labs Wave/424 IC attack: official/period evidence establishes 4×4·24-bit/96k converters·TRS card I/O·ASIO+OMS/MIDI and Dec 1999 Mac driver;no evidence-grade ADC/DAC IC markings recovered. Retain ? ADC·? DAC.
• P34 · Darla24 converter attack: architecture/rates/DSP now strong, but no evidence-grade exact ADC/DAC part numbers recovered. Do not borrow converter ICs from Darla20/Gina20 or later Echo24 products.
• P35 · VX222 converter attack: original VX222 exact converter chips remain unresolved. VX222v2 manual gives 24-bit ADC/DAC architecture but is a later revision and cannot identify original VX222 ICs.
• P36 · Sound Blaster Live Mac omission check: Macworld Dec 1998 reports Creative announced a Mac port;surviving official Creative Mac driver supports OS8.6–9.x but later release evidence is required. Announcement alone≠released 1999 Mac support→do not insert in 1999 table.
• P37 · LynxONE omission check: LynxONE hardware is period-correct but Mac ASIO 2.0 release trail points to 2000. Official Lynx: OS9 ASIO only,no Sound Manager,no OS X;5V PCI/G5-incompatible. Place in Part2,not 1999.
• P38 · CreamWare/other exclusion sweep: Pulsar II/software 2.0 ships for Windows+Mac May 2000;Mac support evidence belongs Part2. Mixtreme period coverage is Windows. Marian/SEK'D evidence found is Windows-centric. No safe 1996–99 Mac insertion from these.
• P39 · SeaSound SOLO omission discovery: Dec 1999 EQ review explicitly describes a cross-platform Windows/Mac PCI card+2U interface and says reviewer tested Solo on both Mac and Windows;package includes Mac+Win95/98 drivers. This is actual 1999 Mac operation,not announcement-only. SOLO is therefore a strong missing 1999 table candidate. Hardware: custom PCI card+DB25 to rack·coax S/PDIF on PCI card·24-bit/96k A/D+D/A system·2 mic pres+instrument/line paths+MIDI. Later preservation FAQ says no OS X driver. Exact PCI electrical fields and converter ICs require dedicated pass before canonical insertion.

Roland RPC-1 2001-02-15

• Mac:R-BUS PCI card. Mac OS 8.6+.
• Mac driver set:
  
  • Sound Manager=only 16 bit 2-channel data.
  • ASIO2=ASIO2.0 driver,ASIO=ASIO2.0 driver without software monitoring,ASIOv3=ASIO1 driver for Digital Performer.
  • OMS 2.3.8 MIDI driver.
• I/O: 8-channel bidirectional R-BUS over 25-pin D-sub;up to 24-bit/96 kHz with compatible Roland R-BUS equipment.
• Driver provenance: Roland explicitly states the RPC-1 drivers were designed by M-Audio. The Mac manual itself also exposes M-Audio naming in the Windows driver components (“M Audio Delta ASIO”/“M Audio Delta EASI”). This strengthens the documented RPC-1/M-Audio relationship,but PCI-controller/electrical identity with Delta R-BUS is not promoted without direct board/controller evidence.
• OS X: later Roland support documentation cites Mac OS X 10.4.2 as an example supported RPC-1 environment. This proves an OS X branch existed but does not establish 10.4.2 as its first/minimum version;overview therefore remains conservative at 10.x.

Creative Sound Blaster Live! for Macintosh (CT4875) 2001-03-21

• Model: Sound Blaster Live! for Macintosh=CT4875. CT4870 is a separate Creative model and receives its own row from the first Mac package that explicitly supports it.
• Timeline:
  
  • 1999-01 — Creative announced plans to port Sound Blaster Live! to Macintosh.
  • 2001-01-24 — announced as nearly ready.
  • 2001-03-21 — available;$149.99;Creative directs users to http://www.soundblaster.com/products/macintosh/.

Creative Sound Blaster Live! Value (CT4870) 2002-07-11

• Placement: Creative's Macintosh v1.1 web update explicitly says it supports Mac OS 8.6–9.x and was tested on CT4870 as well as CT4875;this is the first direct released-Mac package currently proven for CT4870,so it gets its own row rather than being merged with CT4875.
• Hardware identity: Linux/Creative PCI IDs identify CT4870 as an EMU10K1-based Sound Blaster Live! Value with AC97 codec;PCI vendor/device 1102:0002,subsystem 8028:1102. Exact AC97 codec part and card-side PCI electrical fields remain ?.
• Do not back-date CT4870 to the 2001 Macintosh retail-card launch:that launch is CT4875-specific. CT4870 enters only when Creative explicitly supports it in the Mac driver package.

• Mac: Echo’s driver architecture explicitly places Gina24 in the newer Echo24 ASIO family;OS 8/9 ASIO only,Sound Manager unsupported. Later unified manual=8.6+.
• Converters: ~AK5383 ADC ('99)·~AK4393 DAC ('00') pending primary/board-photo confirmation.
• Revision caution: Echo-derived driver code shows Gina24 revisions using DSP56301 and DSP56361;do not flatten production to one DSP IC.
• Laptop boundary: Gina24 is a desktop PCI product;do not create a CardBus Gina24 row. Echo’s actual CardBus systems were Layla LapTop/Mona LapTop.
• PCI: Echo/Linux IDs expose the onboard Motorola DSP itself as the PCI device (56301=1057:1801;56361=1057:3410); Motorola HI32 is PCI 2.1-compliant,32-bit/33MHz and supports PCI mastering.

• Mac: unified Echo manual=OS 8.6+;OS8/9 ASIO only;OS X 10.1.3+. Manual explicitly places Mia in the newer Echo24 ASIO family with Gina24/Layla24/Mona.
• Hardware: PCI bus master·!AK4528 codec ('00). Host PCI requirement is not promoted to card-side PCI revision.
• PCI: Echo/Linux IDs expose the onboard Motorola DSP itself as the PCI device (56301=1057:1801;56361=1057:3410); Motorola HI32 is PCI 2.1-compliant,32-bit/33MHz and supports PCI mastering.

• Mac Classic: period TC advertising requires G3/G4 PCI PowerMac+Mac OS 9;Apr 2001 EM gives Mac OS 8.6 minimum. Initial product was Mac-only;PC support came later.
• OS X: PowerCore system 1.7 supports the existing PowerCore PCI under Mac OS X. Surviving TC documentation specifies Mac OS X 10.2+,G4/800 MHz+,and VST or Audio Units host software. Period SOS coverage likewise states system 1.7 gives existing PCI PowerCore cards full OS X/Audio Units support.
• Identity: TC documentation groups PCI/Element under same hardware specs;Element treated as bundle/product identity,not duplicate physical row.
• Electrical caution: “3.3 V power supply” wording is not promoted to 3.3 V PCI signaling;keying/signaling remains ?.
• PCI revision: TC compatibility documentation states PowerCore PCI meets PCI 2.1 and runs in PCI-X G5 slots;therefore card-side rev=2.1. 32-bit 33/66MHz+206×119mm remain from TC manual. Signaling stays ? until direct keying/electrical proof;3.3V supply wording alone is not signaling proof.

• Platform/PCI: IC Ensemble ICE1712/Envy24 controller family;PCI 2.1·32-bit/33 MHz·bus-master. Linux identifies VX442 with its own subsystem ID 0x12143CD6 inside the same low-level family as Midiman/M-Audio Delta cards.
• Midiman link: photographed Rev-D PCB is explicitly silk-screened “© MIDIMAN, INC. 2002/3/4”. Treat VX442 as a distinct Digigram product/board on the Midiman/M-Audio Envy24 platform,NOT as a rebadged Delta 66/1010LT.
• Closest Delta relation: later Delta 66E and VX442 both use 4-ADC/4-DAC AK4524 codec architecture+CS8427 path in ALSA;GPIO/control implementations remain separately defined,so hardware identity is not collapsed.
• Converters: photographed Rev-D proves !2× AKM AK4524VF;driver code independently defines VX442 as 4 ADC+4 DAC AK4524.
• Electrical revisions: photographed Rev-D is dual-keyed/universal=3.3/5V signaling. Earlier VX442 production was not universally G5/PCI-X compatible;Digigram’s 2004 upgrade added 3.3V-bus compatibility,so overview signaling remains var rather than flattening all revisions.
• PCB evidence: Rev-D·“MADE IN TAIWAN”·Midiman 2002/3/4 copyright;rear compliance label identifies VX442 and Digigram. Physical size remains ? until measured/documented.
