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

(rather than being an unresolved > query) https://xkcd.com/979/ There are a couple of things now where I know that if I try to find sources, I'll find myself. The details of how id Software's game /Quake/ killed Cyrix, the CPU company, because Quake used a very clever method of interleaving FP ops with integer ops that didn't use the same registers, allowing the Pentium core to essentially run them at once. The Cyrix 6x86 core was quicker -- I bought one myself, what more can I say -- but it couldn't interleave FP and int ops like that, so it ran Quake like a dog. And as Quake was *the* most demanding game around in 1996 or so, and had a super convenient built-in "timedemo" feature, all the magazine's benchmarks used Quake. So 6x86s got hammered, even though on literally *ALL* OTHER X86-32 CODE THEY WERE QUICKER, they got bad reviews, and Cyrix ended up getting acquired by Via. Or the problems with AMD fglrx on a Toshiba Satellite Pro P300A. That'll be me, too. The weirdest one, though, was when I was given the honour (?) of moderating my first item at the World SF Convention. It was a collection of silly games. I'd never heard of one of them. I Googled it. I got my own blog as the № 2 or № 3 hit. _That_ was odd. -- Liam Proven - Profile: https://about.me/liamproven Email: lpro...@cix.co.uk - Google Mail/Hangouts/Plus: lpro...@gmail.com Twitter/Facebook/Flickr: lproven - Skype/LinkedIn: liamproven UK: +44 7939-087884 - ČR (+ WhatsApp/Telegram/Signal): +420 702 829 053

(rather than being an unresolved query) A related anecdote (that must surely happen often to ARD, Chuck, Allison, and a few others), . . . A friend of mine did hobbyist holography, with a ton of sand in a waterbed frame on stacks of tires, . . . There used to be only one REAL professional photography supplier in the area, where you could get sheet film, glass plates, etc. One time, she noticed an Eastman glass plate emulsion that she hadn't seen before, so she asked the staff about it. "Well, I personally don't know anything about it, but I hear that we have a customer who knows EVERYTHING about that stuff, and we'll get them in touch with you!" When she got home, there was a message on her answering machine, "Hi, this is George at Alpha Photo. We have a customer who wants to know about a new Eastman glass plate emulsion. Would you mind telling them what you know?" Guess what? YOU are the expert that they will put you in touch with.
