Gave it the dust-off and vis inspection - Base is a Sun 3/160 system, Sun backplane, 3004
processor and memory cards. it has a non-VLSI CV SCSI/2xTTY card.
The VME terminator cards are CV-proprietary, and are switchable between "VME"
and "CV" mode, not sure what the difference is yet.
The case is CV-specific, all drives are front-mounted along with the power supply. Old-IBM
type superstrong reinforced-plastic skins.
The "heart" of the CADDS system is the CV-GPU, two cards connected by 3 ribbon
cables. One is a Multibus "interface card", the
other is the VME processing part, with 7x AMD 2901 bitslice processors. According to docs,
the "GPU" system can be anywhere in the
network displaying on a remote terminal if desired, which differs from SGI-type systems.
Not sure exactly what is done in the GPU yet.
The framebuffer is a seperate VME card, with a unusual DB-25 connector to the monitor that
I haven't traced yet. There is also a
bridged Multibus tablet interface card. I have docs, but they don't go very deep into
hardware.
Unfortunately, it looks like it uses a dongle for protection, which I don't have. Good
news is that it shouldn't be too hard to workaround,
given that it is a ca 1988 machine.
It came with full ComputerVision "4.2 UNIX release 4" tapes, SunOS 3.2 and 3.4
upgrade, SunWrite/SunPaint, CADDS, and some other stuff.
Gave me a smoke signal on the p/s test, from a cap on the VME terminator board. Everything
else looks O.K., except for a broken termpwr
wire in the SCSI card.
