Re: Data General/Rolm milspec systems
RAF Chicksands, and to Ops building probably couldn't withstand anything bigger than a AK 47 or M16 hit. The RAF commander couldn't ever get into our building. I think he was in charge of grounds keeping, Etc. USAFSS , before they changed the command name = NSA. On Fri, Sep 6, 2019 at 1:10 PM Jeffrey S.

I guarantee they don't do everything the same way (case in point RB730 controller initialization) but both will be insightful. My own Unibus (and Qbus and VAXBI) experience is with comm drivers not storage drivers so I don't have any insights on block transfers and purges, unfortunately. I'm excited for the results of this. -ethan

I am working with some developers trying to figure out the data words and how they work on a Navy AN/UYK-19 computer. I have some sticktime on the Eclipse machines.

The computer was suspended on wires in a hangar and, while running, was subjected to simultaneous blows from heavy pendulums on either side.

If a non-consecutive access is required (transfer restart, compare etc) then the data path must be purged first. In the case of a write this will flush any residual bytes to memory and for a read it will ensure that fresh data is loaded to the buffer on the next access. At least that's my interpretation from reading 2.6.2.2 I'm not sure if the adapter needs to request the purge at the end of each block transfer. The driver may do this anyway but I'll have to check the source listings. Matt
Re: ROLM - Dat general 1602 - AN/UYK-19 computers.
We had a DG ROLM at my last base. Not Navy, but USAF. I don't remember which model, but it was a pretty reliable system. I have ideas, but not sure why we needed a ruggedised computer next to a potato field.
