I need to update my link for the old ClassicCmp archive that Kevan Heydon had on his site. I remember there being some talk about moving this but I guess I failed to update my link. If someone could e-mail it to me at sellam(a)vintage.org I'd appreciate it very much.

You can order the "i960 Microprocessor Electronic Library" CD-ROM from Intel's literature centre. The order number is 272743-002. Or look on the Intel web site. -- Mark

IBM 3725 In Central Illinois

It is big, it is heavy, it is blue, but it isn't a computer. It's a PU (Physical Unit) Type 4 as seen from an SNA network standpoint, and is more commonly known as an FEP (Front End Processor) - Think of it as the I/O interface for a mainframe. This is the thing that a 3274 would talk to - that box we were discussing here a few days ago. The CPU is a PU Type 5, the 37x5 is the PU Type 4, the 3274 is a PU Type 2 and they all coexist happily in their own roles on an SNA network. Each PU Type can initiate or resond to certain types of network traffic; it's very hierarchical and structured. -ethan ===== Even though my old e-mail address is no longer going to vanish, please note my new public address: erd(a)iname.com The original webpage address is still going away.

Mike also got a Motorola National did the BLC80xx series if memory serves, decent intel compatable multibus. Slightly surprized to see a ISBC80/20 cpu as they nominally had National cards. I think I have the manual for the BLC80204 8080 card that was the national equivelent of the ISBC8020. Allison

SIMM Remover tool

by technoid＠cheta.net

My Sparcstation 330 has 24ea 30-pin simms onboard. Removing them was a problem for me when I was diagnosing bad ram. I found that a 7.65x54mm cartridge for my 100+ year old Argentine Mauser rifle was the perfect tool for working with this type of simm socket. I suspect any full-metal-jacket round with a "Spitzer"-type nose (pointy) will work such as 7.62x39 Warsaw Pact or 5.56 Nato will work just as well or better. The trick is to start with the 'lowest' simm - the one that is 'under' all the others. Insert the nose of the round into the hole on one side of the simm, press down to disengage the clip on the socket and lever against the simm 'below' the one you are removing. The last simm is more difficult because there is no simm 'beneath' it to lever against but the tool is still helpful. Especially if your video card is like mine, piggybacked onto the motherboard. I lever against it for the last simm. The copper jacket is soft and will scratch but does not appear to shed material which is good because copper is conductive.... These minor scratches will affect accuracy when the round is fired so don't use this 'tool' as ammunition in a competition! Yes. I drew a five-shot, one-hole group at 110yards with my Winchester 30-30 rifle over open-sites one day. Can hit a quarter at 300yd with a scope..... As with all explosives, due care is indicated.....

The Intel 80/20 is an 8080 Single Board Computer. This is the type of system built into industrial systems. Paxton

...back then we had just enough ram to get the job done, today we have enough ram to run solitare instead of getting the job done... ;)
