Hi! I am jumping into this thread late, but has anyone checked JDR in CA? I see that they still have many of these 74xxx series chips. I am interested to tell people about them that buy the 6 Kaypro "8" 's [upgraded / modified Kaypro 4's 1983's] I will be selling on eBay in May / June. Prices are cheap - $0.25 up to a few dollars for Z80's etc. I even became a "commercial customer" with associated small discounts in the 1900's - not good for the bank account howerver!. Many of the others suppliers have gone out of business naturally from that era. I was pleasantly surprised they still supply these so inexpensively.. Just a thought in case it is useful and some did not know about JDR. Frank In a message dated 3/1/2008 8:33:00 P.M.
