Last sunday I went 35 Km away to pick a broken MDD Uni 1.25 with Radeon 9000
128 Mb and a Sonnet FW 400 card. Also a broken Samsung PSU. Ad no drives. And 1 pound of dust.
That model is 166 bus (at last!) and I have been fighting until today with 10 ATA drives (only 5 past SMART) to get clones of Instant DAW and clones of my PB 17" installs that include Panther and Leopard.
I borrowed my G4 Sawtooth 1.8 dual with a Digi 001 to a drummer to allow him record 16 tracks at once using his behringer 8 ins+ADAT.
you forgot to mention your OS9 machines.
PowerPC:
G4 MDD 867 Dual Mac OS 9/Panther Audiomedia III
G4 DA GHz Dual Mac OS 9/Panther Digi 001
G4 MDD 1.25 Mac OS9/Panther/Leopard Sonorus STUDI/O M-Box
PowerBook G4 GHz 17" Mac OS9/Panther/Tiger/Leopard shares the M-Box and the M-Audio FW duo
My most used cards are still the FW Solo+FW Audiophile + Focusrite LS56 that go with an
Inteli5 2500K oc 3.4GHz nVidia 730 Win 10 64 (Planning on go Capitan soon) Protools 10+12
Mac Pro 2.1 2xQuad 3.0 8GB RAM nVidia 210, 9400, 7300 Lion + El Capitan (Planning on go Win 10 soon). Protools 10
All those machine are actives and running.
For the future decide to use the SONORUS Studi/o on a maxed Windows XP and build a system with W98/WMe around a Guillemot Maxi Sound ISIS that have an onboard 4 Mb sampler and a fine I/O box.
I have board+cpu+heatsink+RAM :
3 Intel 775 Quads to fulfill that but also
board+cpu+heatsink :
2 Pentium D, 2 Pentium IV a Pentium III and a Pentium 2
But only 2 good ATX 12cm fans boxes, 3 old PSU and no money to invest on drives till.
Next week I hope to send recycling all Pentium D and below If I get a stable W98 Setup for the ISIS.
