Post by: smilesdavis on August 26, 2026, 12:24:34 AM
Digigram Laptop / PCMCIA Audio Cards on Macintosh — PCXpocket & VXpocket Anthology

Scope: Digigram Type II PC Card / PCMCIA laptop audio hardware with documented Macintosh support: PCXpocket / PCXpocket AD / PCXpocket v2 → VXpocket v1 → VXpocket v2 → VXpocket 440.

Mac chronology: PCXpocket launched in 1997; PowerBook support appeared in late 1998. VXpocket followed in 1999 with Sound Manager + ASIO, VXpocket v2 and VXpocket 440 in 2000, and Mac OS X drivers for VXpocket v2 / 440 on 21 October 2002.

1997–1999 — PCXpocket / PCXpocket AD / PCXpocket v2

1997 — PCXpocket: Digigram's first professional laptop sound card; Type II PC Card; 2 balanced mic/line inputs; 2 unbalanced line/headphone outputs; PCM linear + MPEG audio; simultaneous record/playback; onboard Digigram audio/DSP processing. Macintosh support was not available at launch.

Fall 1997 — PCXpocket AD: PCXpocket variant with S/PDIF input and time-code input; advertised alongside PCXpocket by October 1997.

Late 1998 — Macintosh support: Digigram introduced a PowerBook Sound Manager driver supporting PCXpocket-family cards on PowerBook 2400, 3400 and G3 with Mac OS 8.1+, Sound Manager 3.3+ and PC Card Interface 3.0+.

4 February 1999 — surviving Digigram Mac download page: explicitly lists PCXpocket AD and PCXpocket v2.

July 2000 — PCXpocket software distinction: Electronic Musician explicitly warned against treating the PCXpocket line as a mainstream music-production interface:

“Unfortunately, the PCXpockets don't support popular, commercially available music software. The PCXpockets are special-purpose devices intended for testing, measuring, and industrial applications, and they include onboard processing for which custom applications must be written, often by third-party software developers.”
Electronic Musician, July 2000, p. 194 (https://www.worldradiohistory.com/Archive-All-Music/Electronic-Musician/2000/Electronic-Musician-2000-07.pdf#page=180)

Mac distinction: PCXpocket AD / v2 had Digigram Sound Manager support, but the documented third-party Mac music-software compatibility path is the VXpocket family: Digigram's 23 November 2001 chart lists Logic Audio, Digital Performer, Cubase, Nuendo, Peak, Deck, SpectraFoo, Reason, Spark and others via ASIO and/or Sound Manager.

Installed Mac components: Extensions — PCX Driver, PCX Enabler, PCX Library; Control Panels — PCX Control; Apple's Sound control panel also required.

1999 — VXpocket v1

Hardware: Type II PC Card; 24-bit converters; 2 balanced mono mic/line inputs; 2 balanced mono outputs; stereo S/PDIF input/output; S/PDIF consumer / AES-EBU professional mode.

Original Mac requirements: Mac OS 7.6+; QuickTime 2.5+; PowerBook 2400 / 3400 / G3; standard Type II PC Card slot. Mac OS 9 was explicitly supported; Mac OS X was explicitly unsupported at this stage.

PowerBook compatibility / why the 1400 does not work: the VXpocket requires more than a physical Type II PC Card slot. Apple's PC Card implementation changed between the PowerBook 1400 generation and the later PCI-based PowerBooks.

Apple documents PC Card Manager 2.0 for the PowerBook 520 / 540 / 190 / 5300 / 1400 families. PC Card Manager 3.0 supports PCI-architecture PowerBooks; Apple's 1997 developer documentation specifically identifies the PowerBook 3400 and 2400 as this later generation.
Apple Directions, August 1997 — PC Card SDKs (https://www.savagetaylor.com/wp-content/uploads/documents/Apple_Directions/Apple_Directions_1997/Apple_Directions_08-97.pdf)

This matches Digigram's VXpocket hardware support boundary. Digigram's December 1999 FAQ lists PowerBook 2400, 3400 and G3.

Sound On Sound — February 2000: “Due to hardware issues related to the PC Card interface, the VXPocket won't work with the PowerBook 190, 5300, and 1400 series.”
Sound On Sound — Digigram VXPocket, February 2000 (https://www.soundonsound.com/reviews/digigram-vxpocket)

AudioTechnology — Issue 11: Brad Watts tested the VXpocket in a G3 500 MHz PowerBook, PowerBook 3400/200 and G3-upgraded PowerBook 2400, then states: “These are the only Apple models that support the card – anything above the 1400.”
AudioTechnology Issue 11 — Digigram Pocket VX, p. 88 (https://www.audiotechnology.com/PDF/11/AT11_Digigram_Pocket_VX_Audio_Interface.pdf)

Compatibility boundary: the PowerBook 1400 has two Type II PC Card slots, so the incompatibility is not caused by the absence of PCMCIA hardware. The 1400 belongs to Apple's older PC Card Manager 2.0 / non-PCI PC Card architecture; VXpocket support begins with the later PCI / PC Card Manager 3.0 PowerBook generation.

PC Card Manager 2.0: PowerBook 520 / 540 / 190 / 5300 / 1400
PC Card Manager 3.0 / VXpocket-compatible generation: PowerBook 2400 / 3400 / G3 and later supported PowerBooks.

1999 FAQ audio formats: PCM 8/16-bit at 8 / 11.025 / 16 / 22.05 / 32 / 44.1 / 48 kHz. Later Mac ASIO drivers added 24-bit operation.

Sound Manager / ASIO behavior: both drivers could be installed together but could not access VXpocket simultaneously. For ASIO use, VXpocket was left unselected as the Mac Sound Manager device, allowing built-in Mac audio through Sound Manager while VXpocket served the ASIO application.

Input/output behavior: analog or digital input could be recorded, not both simultaneously; analog and digital outputs operated simultaneously; VX Control selected analog/digital input and mic/line mode; hardware monitoring routed the selected input directly to VXpocket output.

Multiple cards: two VXpockets in one PowerBook were not supported by Digigram's contemporary Mac Sound Manager/ASIO implementation.

2000 — VXpocket v2

Hardware: Type II PC Card; 2 balanced mic/line inputs; 2 balanced outputs; stereo S/PDIF I/O; LTC/SMPTE time-code input; stereo headphone connection on breakout cable.

Mac support: Mac OS 8.1+; Sound Manager 3.3+; PowerBook 2400 / 3400 / G3 / G4; standard Type II PC Card slot; Sound Manager 16-bit; ASIO 24-bit.

VX kit 3.1c: Sound Manager 2.7.4 + ASIO 2.7.4. The preserved ReadMe identifies Version 2.7.4, September 2001 and installs Digigram VX Driver, VX Enabler, VX Library, VX Control and Digigram VX ASIO Driver.

↑ Index (#post_digigram_laptop_top)


2000 — VXpocket 440

Hardware: Type II PC Card; 4 balanced mic/line inputs; 4 balanced outputs; stereo S/PDIF I/O; LTC/SMPTE input; stereo headphone connection.

Mac support: Mac OS 9.1+; Sound Manager 3.3+; PowerBook G3 / G4; standard Type II PC Card slot; Sound Manager 16-bit; ASIO 24-bit.

Active-I/O limitation: all eight analog channels were not available simultaneously at maximum operation; Digigram documented 4-in, 4-out or 2-in/2-out configurations according to active I/O and audio format.

VX kit 4.0b: Sound Manager 2.8.0 beta + ASIO 2.8.0 beta. Driver 2.8.0 introduced VXpocket 440 support, a new ASIO engine, selectable active ASIO I/O and revised VX Control.

2.8.3 ReadMe: explicitly covers VXpocket, VXpocket v2, VXpocket 440 and VX222; VXpocket 440 requirements are Mac OS 9.1+, Sound Manager 3.3+ and PC Card Interface 3.0+.
