HP 1000

Hi, our museum recently got "some" (a dozen) HP 1000 with "some" spare parts and "some" tapes. Currently we're building up some of the stuff to get a running system. For now, I've put a 2100S, a 2117 (1000F), I/O extender, two 7970B tape drives (one with the 200/556/800 bpi option), one 2748A tape reader, one HP 8100 tape punch (basically a Facit 4070), a HP130C (?) rackmount oscilloscope, and a 7905 disk drive with its 13037C controller into the three racks we have. Included are the original distribution tapes of RTE-II, RTE-III, RTE-IIIM, RTE-4, RTE-4b and RTE-6/VM, DS/1000, Signal/1000, Fortran, etc., a huge pile of paper tapes (original HP), and nearly all paper documents (manuals, schematics). But some parts are missing, so here are my (first) questions: - Does someone have the schematics of the 12555 dual D/A converter card? They are not on bitsavers yet. We've attached the D/A card to the scope and ported the PDP-8 kaleidoscope program to the HP2100. There are a lot of glitches in the analog signals and we want to find out where they come from (it's not a software bug, all test programs on all D/A cards we have show the same symptoms). - My only diagnostic tape (24396-13501 rev. 1926) has read errors in file 7 and in the last files. There is (was) a file in the SIMH package called hp2100_diag.txt that insinuates that there must be a TAP image of the 24396-13601 rev. 2040 diagnostics tape. Is there a chance to find it somewhere? I really need a working diagnostics tape. Christian
