I've found an Ampex Megastore ISA card that interfaces via a 50-pin header. I've got the software for it, but no manuals, so I don't know what it's supposed to connect to--it doesn't seem to be SCSI. Any ideas? Cheers, Chuck

And why is the brunette girl in the background making 'steering wheel - driving motions' that seems to make the much taller older gentleman next to her seem very concerned? Hehe.

Strange request.

by Mark.Brennan＠ie.fujitsu.com

Hi, My name is Mark Brennan, I am a systems engineer with Fujitsu in Ireland and I have a request I am looking for some help with. My request is some what strange to say the least. Since I joined Wang Computer in 1988 I have been collecting Product Brochures on various computer systems it started of with Wang Vs server systems. For the last few years I have been trying to collect old product/info/fact/marketing brochures on various computer systems with very little luck, as in the future I hope to set-up a web site with details and overviews of them. I have managed to collect some information on, DG/HP/Wang/Netframe/NCR/Tandem/DEC/Sequent/SGI/Siemens-Fujitsu/Pyramid/Apoll o/Cray/KSR/Ncube/ICL/Compaq etc, I was wondering whether or not you may have or know where I maybe able to get my hands on any old product brochures/fact sheets etc on any of the HP systems/servers, I know that my request is at best strange but any help would be great. Anything that is sent to me I will copy and return the originals it people still need them that is. Regard and thanks again markb.

I thought I'd killed one (at $180 then!) by installing it backward and then tossed it on the floor in the engineering lab. some days later after pulling from the bottom of my shoe I tried it again and it was still alive. The ram however is definately suspect. But I've seen IO messups with 8008 and with scanned displays and keyboards are harder to look at. It would be goof if you could run a different program and see it's results. We used a set of ROMs all different to test. They were short programs that would either loop or do something and halt. For example we had one that would write (this was a time display) 00:00:00 then increment all the displays without doing anything else. Another would write a 8 tot he last display and halt. the most useful ones were those that would repeatedly loop input or output to a port. Very handy as back (1973) then logic analysers were not to be had and a 15mhz dual trace scope was the usual tool. Allison

There is a second picture of the "hot geeky blond girl" which promotes her to "hot geeky blond 'nice legs' girl" :-) If I ever go to a VCF (in Germany), I must hire one of those girls you see on the bonnet at car shows. It will not matter what old stuff I exhibit, *my* stand will be visited most! :-) - Henk, PA8PDP. BTW. Thanks for sharing the pictures!
