I guess you don't have the manuals for this. AFIK I have the full set of manuals for BASIC 5.1 along with a bunch of other useful related HP manuals such as the HP 9826/9836 and HP 9000/300 Series Computer Installation manuals, various peripheral configuration manuals, BASIC 2.1 and 3.0 manuals, HPL manual, Pascal manuals, Self-Study Guide to Instrument Interfacing using HP Basic, FSD Customer Engineering Manual and more. This stuff needs to be made available to the everyone. Al has asked about borrowing the stuff and scanning it and I've told him that he can but we haven't done anythng to make it happen yet. But it's about time that we did. How about it Al? Do you have time to do this stuff yet? --- I'll make time to get it done. I have a couple of other manuals to get on line (like the other PASCAL manual and the 9836 service manual) Was talking to a friend of mine today who makes a little Ubicom board and I suggested he implement an HPIB interface on it and implement enough of a emulator to provide an HPIB peripheral to Ethernet interface. Then, you could have a box on the net simulate the rest.
