We recently managed to (finally!) get our HP 2116 machines out of 'deep store'
and into the light of day, and some initial cleaning work was done on the
panels earlier.
I did a quick inventory:
2116B
2116C
2160A (PSU)
2161A (PSU)
2748A (tape reader)
HP1016C (two - 512 track drum)
One of our guys managed to flip the front door catches (the keys for the
machines are long-gone), so I was able to take a board listing too:
2116B:
slot board
1 pwr fail / AR
10 sense amplifier
11 sense amplifier
12 sense amplifier
13 sense amplifier
14 driver switch
15 driver switch
16 inhibit driver
18 inhibit driver
20 DML
22 sense amplifier
101 A101
102 A102-105
103 A102-105
104 A102-105
106 A106
107 A107
108 A108
110 EAU logic
111 EAU timing
116 DMA word count
117 DMA word count
118 DMA address enc.
119 DMA control
120 DMA packer
201 A201
202 central interr.
211 I/O multiplexor
214 tape reader
216 I/O multiplexor
218 buss loader
2116C:
slot board
101 A101
102 A102-105
103 A102-105
104 A102-105
105 A102-105
106 A106
107 A107
201 A201
205 A108
206 MDB / A13
207 power fail
208 power fail
209 power fail
210 power fail
211 power fail
212 inhibit driver / A4,6,16,18
213 inhibit driver / A4,6,16,18
214 inhibit driver / A4,6,16,18
215 inhibit driver / A4,6,16,18
216 MMD / A2
217 sense amplifier
218 MMD / A2
219 driver switch / A8,9,14,15
220 MDB / A13
things found kicking around in the 2116C case:
Core stack with connectors labeled A1, A2, A3, A6 (made by Ferroxcube
corporation)
Core stack with connectors labeled A1, A2, A3, A6 (made by Ampex)
Core stack with connectors labeled A1, A2, A3, A4, A6, A7 (international
scientific)
'short' board, HP assy. 02116-8015
'short' board, HP assy. 02160-60031
power fail board (identical to the ones in card slots)
unknown full-size board, HP 1150-1198.
Most of the boards sitting in the card slots are just loose, i.e. not plugged
into the backplane, so there's no guarantee they're in the right place (the
bottom row of the 2116C machine looks particularly disorganised).
Anyone familiar with the systems know if this is anything like two machines'
worth though? Or is it some sort of dual-cabinet system, and one crate was
likely just I/O with the other for CPU? Nice to finally see inside them
anyway, as for all we knew they could have been completely stripped out inside...
I *assume* the pair of drums go with them, but there's no guarantee there (I'm
just not sure what they *do* belong with if it isn't these machines :-)
