Hi Roger, I don't know, if you still have your 4041, but I have the solution for your problems. I found some DC-100 tapes, changed an ASCII keyboard, so I could type in the necessary commands and stored them on tape. It works great with a notebook and terminal program. Perhaps we can make a change, because I am looking for the programmers reference and operating manual (e.g as PDF files) as well as for the Utility ROM pack and ROM pack manuals. I would appreciate hearing from you.

I've got a hankering to play with the IEEE-488 bus but can't see paying the current prices that most people seem to want for a IEEE-488 controller for a P.C. I've acquired an Tek 4041 with 512-K and the rom Basic development firmware and even the manuals. But I don't have the (optional) keyboard OR the diagnostics tape. If I could find this tape then I could simple use a RS-232 terminal for program input. I've even got a nice HP 150 that could serve as a terminal, but I need that tape!! Speaking of which, this thing uses a DC100 tape. Know where a soul can find any of these tapes for less that $25.00 each? I know that GP-IB controllers are considered kind of low life - but for some reason I'm hooked on this one (could be the 68008?). Hell, you know what? I'm afraid that old computers are going to be as addicting as old analog synthesizers and Tektronix mainframe o'scopes. Thanks all.
