Hello and welcome to the list. There are quite a few PDP8 owners/enthiasts here. I've got an 8/e with 32K words of core, RX01, TU56 and PC04 on my desk. I've also got an 8/a upstairs somewhere, but it's got the 8/e CPU board set in it, not the hex-height 8/a CPU board. I am told that was a stnadard variant. I assume you've found bitsavers as a useful source of manuals. [...] I asusme those are the interface board for the spectrophotometer. You may well find theycan beused for other things. I'd probably take the time to trace out the schematics (they don/t look all that complicated, and you have the Omnibus pinouts as a reference), and see what they really do. That ADC module (or was it a DAC?) in the middle of one of the boards looks 'fun' Nice. Agian, plenty of ASR33 owners here... I would strongly advise you to get the maintenance manuals and go ove the lubrication points before running thsse 'seriously'. Oil is a lot easier to find that spare parts :-) I have a Z90 (which is essentailly the smae machine but factory assembled and with differnt options as stanard). What parts are missing from yours? ^^^^^ Qbus, surely? -tony
