Honeywell/Bull DPS-6 deskside info?

[Dave G4UGM]

The DPS6 is a very different animal to the GE600 -> GE6000  > Level 66 => DPS300 which were as far as I know all TTL or LSI TTL....
... The CPU was built on wire wrap boards which were around 14" or 16" square (say 35cm) and which slotted into a backplane.
.. the machines had an extensive test suite which the CE ran weekly. This could vary the voltages to the logic chips....
.. when a faulty board was found they were usually repaired on-site, there was a board tester shipped with each system to identify chip level faults.
.. this contrasts with the earlier H3200 we had which was fixed by board level repair..

The CPU and Memory were in separate cabinets, much like the 360/67 but Honeywell kept the same layout when moving from core (I think the GE6000/H6000 were core) on to D-Ram in the L66.
The CPU number and I think the RAM start addresses were all configured on switchs, so it was possible to split a Dual CPU machine into two singles for testing. 

The peripherals came from MPI a joint venture with CDC

There are more ramblings, (not from me) here:-
