The 670-9150-01 looks like a Tektronix part number. Possibly a waveform
generator from some sort of test system.
Tektronix made various custom boards based on the ISA and PCI
interfaces. Most were used in systems they sold.
I have a PQA 200 MPEG analyzer based on a Compaq PC loaded with
Tektronix boards, all with 670-xxxx part
numbers.

Howdy, guys.
I've got an 8-bit ISA card here that I pulled out of an IBM PC/AT 5170
machine (which apparently was a VM/PC development machine at one
point, and contains program code for the PC3277/GA).
I wondered if anybody could help me identify what it might be. Parts
have date codes in 1985; chips of note are 32k in 70ns 4Kx4 SRAM;
intel 8086, 8259, and 8254; and a pair of 12-bit monolithic DACs. I/O
is by one DE9m and one DB25m.
