Due to massive amounts of caffeine & sleep deprivation, Huw Davies said: Kool. I meandered over to Motorola's website last nite, and tho they did not have the datasheets for these chips on the Web, they were available thru their faxback system... so I have the datasheets IMTLF (in my tight little fists) right now. I'm leaving it up to you what I scan in... I'm definately scanning in the pinout w/information, but do y'all want me to: 1) scan in the programming timing information? 2) scan in the fast programming algorithm? 3) scan in anything else? Oh, and tho the chips have a "C" on them (as in MCM68764C) the datasheets say they're N-channel MOS. Unmarked speed chips are 450ns access, but there are some 350ns parts available as well. Anyway, expect to see some info on this arrive over the weekend on my website... as it looks like I may actually have 4 or 5 seconds this weekend to work on it! http://home.northernway.net/~zmerch/geezers.shtml for my geezer computer page.
