IIRC, IBM made several tempest models like the PC, XT and AT. very heavy duty, but never saw one in real life. I picked up a neat IBM part. It's a prototype AT adaptor never used and still in its worn out box. it's basically just a full length AT card with holes for soldering in chips and components. Will go good with my never used PC keyboard and 5150 still in their boxes... In a message dated 8/2/99 9:02:56 PM Eastern Daylight Time, dastar(a)ncal.verio.com writes:
