S-100 history (was Re: CompuPro CPU-Z with IMSAI and Front Panel issues)

Sounds like you have a few stories to tell. My only experience with Godbout gear was using a couple of the full-sized boxes loaded with SRAM cards, serial ports (over a dozen lines) and a MC68K processor board - it was a proof-of-concept prototype for an X.25 WAN router that was a logical descendant of the CompuServe PDP-11-based serial I/O nodes (same architect, different company). I don't remember a single problem with the hardware - rock solid. When the company closed, I gave a 4' stack of enclosures to a friend in town. I should ask him if he's ever done anything with them (I am positive he hasn't discarded them - he's not the type). I have a Morrow Designs OEM ADM-20 terminal that I took with me to VCFmw, but I was unable to get more than baud barf out of it. I should hang an HP 4951 off of it to see what it's really doing. Care to share any interesting stories from the S-100 trenches? -ethan

Joining the list

by dm561＠torfree.net

I see there still are a few folks on Erik's VC forum trying unsuccessfully to sign up on cctalk; wasn't there some talk recently about taking some of the load off Jay's plate and giving approval authority to one or two other people? Or are new members intentionally being discouraged to keep down the volume, etc., as some folks are speculating? mike

Example: My daughter does not save her digital pictures on a computer because it is too much trouble and, besides, there is more room on the memory card. When the room gets too low, she deletes pictures from her camera because they are from last year and who cares about last year.

Xerox Alto on ebay (not mine!)

> Emulators are great for a lot > of things (offtopically, especially running WinXP in a sandbox) but > aren't nearly so helpful when trying to get original hardware working > again... I have to disagree. Only last Wednesday I was single shotting my simulator and the real hardware to find where they diverged. It showed up the fault after a few hundred instructions instead of running for a half a second before crashing (by which I mean the hardware stopping because it detected the loading of an instruction where one of the digits was not binary coded decimal). I am also working on a deeper simulator which models the actual gates of the computer and their interconnections. The source code of this describes the computer in great detail and I would say would be better than real hardware from some purposes. It will also allow monitoring of signals with a virtual oscilloscope and maybe one day, the introduction of simulated faults to test the brains of anyone mad enough to want to see how the original engineers would tackle faults. One day it might even have a 3D graphical interface where you can walk around the machine, open covers and connect your virtual 'scope and the original sounds recorded from the real hardware, like the drum running up.

I didn't buy it, but I spotted a VAX 11/751 with Applicon branding on it at a surplus dealer. I will upload some photos I took to a picasa web album tonight.

Tony and museums (was Xerox Alto..)

Tony, does a week ever pass where you don't feel the inescapable urge to flame those who work at museums, regardless of their knowledge, ability and track record? You are rude and insulting. Yes, damned rude even. How dare you make such sweeping generalisations? If the subject of your disapproval were a particular race or subscribers of a certain religion this would not be tolerated. Yet somehow it is and you get to flap your jaw, spewing out utter nonsense asserting that everyone who works at a museum is an idiot, and we have to put up with it. And *you know full well* that there are plenty of people who work and volunteer at museums on this list. Oh, I'm not one, in case you wondered. ... So, how about this. Have you ever considered that if you slightly adjusted your attitude and learnt to work with people rather than lambasting them, you might actually contribute to the preservation of computer history for future generations. But, no, it's much easier to take the moral high ground and boast about how clever you are and how much of an idiot most everyone else is. Andrew --------------- REPLY: Whoa! Talk about "rude and insulting," and making "sweeping generalizations"... He said he's dealt with "some particularly clueless people at museums;" how did you get "everyone who works at a museum is an idiot" out of that? And if he and Curt decide that based on their bad experiences they won't lend their systems again to a museum, I think that's their choice to make. Finally, to suggest that he hasn't in fact "contributed to the preservation of computer history" is preposterous and highly insulting; I don't see many reverse-engineered HP schematics or extremely helpful posts "working with people" on here with your name on them... Not many of his contributions are relevant to my interests but I for one certainly appreciate the time he spends helping the folks on here, in the HP community and elsewhere (even if his rants are a little repetitive at times) ;-) Sheesh! mike

Xerox Alto on ebay (not mine!)

My point was >that it often has a downside when it comes to getting items to people who are >best capable of preserving them for future generations. My appologies, Jules. I had taken your comment as Yet Another instance of the weekly "eBay sucks because people pay more than I would and, as a special snowflake Classic Computer person, I'm an authority and anyone who pays more than I would is an idiot" thread, when in reality it was Yet Another instance of the weekly "eBay sucks because anyone who outbids me is certainly almost possibly definately as far as I'm concerned, as a Special Snowflake classic computer person, unworthy to own it" thread. I sometimes lack the patience to keep track of the multitude of ways that list members condescend to the world at large. My bad.
