I don't have any kind of parts catalogue, but someone here might. Some
parts are really obvious, but I'll list 'em anyway.
On the motherboard: NEC D765AC (40-pin); eighteen times HM4864P-3 (so I
guess Wang used parity); Intel D8086-2; AM9517/A-4PC (40-pin); Intel
P8253-5 (24-pin); Intel P8259A (28-pin); Intel D8288 (20-pin); two times
HN482732AG-30 (EPROM, 24-pin, in 28-pin socket); D3-6402-9 (40-pin);
AM8255APC/P8255A (40-pin); SCN2661C/C1N28E/CP28028 (28-pin). The rest is
TTL.
The memory board only has RAM chips and TTL.
The board with the funny cable connectors is labeled "LOCAL COMM D.L. BD"
and "9245 - R0M0". The only interesting IC is a 40-pin chip labeled "WANG
2001/377-0508/IMP 03 8402BCA". The rest is TTL.
The "mystery board" which is attached to the above board via ribbon cable
has a Zilog Z80A CPU, and another chip from MOSTEK labeled
"MK3882N-4/Z80-CTC". The rest is TTL. The board itself carries the label
"WANG 9246 A R0M1".
The IBM Mono Emulator board is labeled "P C Emulator" and "WANG
9443-R2-M2" and has two 28-pin EPROMs on it labeled "HN482764G-2". There
are five 28-pin chips from Toshiba labeled "TC5565PC-15". There is also a
40-pin chip labeled "HD46505SP/HD6845SP". The rest is TTL.
And BTW, the date codes on the parts suggest the following manufacturing
dates:
Motherboard: 1983
Memory board: 1986
"LOCAL COMM D.L. BD": 1984
Mystery Board: 1984
IBM Mono Emulator: 1985
