I have a WD 1001-05 (no a PC board). Anyone interested in buying this? Here's a picture of it: http://www.bitsavers.org/pdf/westernDigital/WD100x/WD1001-05/WD1001-05.jpg Last used in the 1990's with my Atari ST. -- Linux Home Automation Neil Cherry kd2zrq@linuxha.com http://www.linuxha.com/ Main site http://linuxha.blogspot.com/ My HA Blog Author of: Linux Smart Homes For Dummies KD2ZRQ
Oooh, that has an 8X300 on it. I've never seen one in the wild. The 8X300 was a stupidly fast (for 1980) Signetics microprocessor. I designed some hardware around it when at Bell Labs in 1986 (which never even made it to the hardware prototype stage). It ran with an 8MHz clock, and could do an entire instruction cycle (fetch, decode, execute) in 250ns. It had a very simple instruction set, obviously (i.e. RISC). To read more about the 8x300: https://en.wikipedia.org/wiki/Signetics_8X300 Bill Dudley retired Bell Labs (among other things) This email is free of malware because I run Linux.

Very nice processors. And you can fry an egg on 'em. Neil, I'm interested in that board, if you can hang onto it for a bit. (thin month here) -Dave -- Dave McGuire, AK4HZ New Kensington, PA
