Folks; I have a BA23 VAX of unknown provenance, which tonight I moved from the project backlog to the workbench. It comes up and passes selftest. But any key I press on the console terminal is repeated a couple dozen times (to the limit of the input line length?). This makes it impossible to interact with ODT. Is this a normal sort of well-understood failure mode? In this session excerpt, the only thing I am sending is <BREAK> (giving me the normal chevron prompt), <ENTER> (giving me the repeated chevrons, sometimes with other characters in the pattern), ?, and h. I did not type any colons at the [XQA0] prompt, though I did try to backspace them. The behavior is the same if I remove all boards besides the KA655-B and 16 MB memory board.

What Makes a PDP-11/35 or 40 Tick?

I wondered if it was fair to list the DEC 23B00A2, etc that hold the ucode as separate parts; they might have been a bunch of 256x4 PROMs, and the separate part numbers were just for the different programming. (Whether differently programmed PROMs count as 'different' parts for the purposes of this table I leave aside.) Looking at my M7232 card, though, I think they may be masked ROMs; the only part number on them looks like a manufacturer applied one with the DEC number. Interestingly, about a third are MMI parts, and the rest are NS. I wonder if neither manufacturer had enough capacity alone, or if DEC just wanted multiple sourcing. (The parts appear to be basically the same, in terms of speed, format, etc so it appears either could have provided any of them, modulo the programme.) Noel

Found on Hackernews but by our very own Seth Morabito... ? This is what makes a PDP-11/35 or PDP-11/40 tick. It turns out to be 441 ICs.

HP9816 PAL16L8

Back when I first used a PAL, I also photocopied the page from the databook, marked up the connections I wanted, and then asked my coworkers how to get that programmed into the device. It was pretty annoying to learn I had to convert it to equations first. It seemed like a pointless extra step when the software was just going to turn around and turn the equations back into the matrix wiring I had just marked up. BLS

Modems and external dialers.

by cctalk＠gtaylor.tnetconsulting.net

Does anyone have any experience working with modems that didn't include internal / auto dialers? They came up in a conversation in a newsgroup and I realized that I know of them, but know virtually nothing about them. I think they were separate devices, which probably means that they likely had separate serial ports to talk to each of them. Did they support some sort of pass through? Or did they really require two serial ports on the host? -- Grant. . . . unix || die
