Hi Ed, I've been trying to use my BA23-based microPDP11/73 recently. I got as far as installing RT11 and Fig-Forth :-) , but then the power supply blew a cap so everything has been mothballed since Friday! My guess is that the A/D won't work if it's for an 11/03 But the D/A sounds interesting! As does the RTC. As does the Load board - I guess that board is there to simulate loading on a PSU so you can test the PSU? Obviously I'm happy to pay for the postage, in fact is sounds like good value! -cheers from julz @P ____________________________________________________________________________________ You rock.
