DELUA technical manual, VAX diagnostic

-----Oorspronkelijk bericht----- From: Rich Alderson Sent: Monday, November 17, 2014 8:05 PM To: cctech at classiccmp.org Subject: DELUA technical manual, VAX diagnostic We have a crumbling DELUA in the VAX-11/780-5 at LCM. There is a copy of the *User's* Manual at Bitsavers, but not the *Technical* Manual. Does anyone happen to have a copy lining the hamster cage floor, vel sim.? The User's Manual refers to a diagnostic, EVDYB, which "runs under the VAX diagnostic supervisor (VDS)." Does anyone here have either of those things, or pointers to them? In the mean time, I'm going to try to get the PDP-11/70 to run CZUAD from a simulated TU58, but I'm told that getting the DELUA into and out of the crowded Unibus backplane is an exercise in bloodletting. Thanks, Rich Rich Alderson Sr. Systems Engineer Living Computer Museum 2245 1st Ave S Seattle, WA 98134 http://www.LivingComputerMuseum.org/ --- I have an RA82 with "VAX diagnostics" on it, but I will need several months before I will be able to access that drive (problems with the VAX-11/750 console line). I only have the User Manual (original version not a copy). Insertion and removal of the DELUA is not more difficult than an RL11. Maybe the DELUA is even easier to insert and remove than an RL11, because the RL11 has a 40-pin BERG header at the *top* side of the module, whereas the DELUA has a smaller (16-pin?) header at the *front*, so the connection cable to the bulkhead is easier to connect on a DELUA. Both boards are "hex", so a bit of "wiggling" helps to get all 6 edge connectors aligned for the backplane slot. - Henk, PA8PDP
