Hi Sam and all, At 01:30 PM 2/24/99 -0800, you wrote: I have both the AMD and Intel data sheets for the 1101(A). They also may be in a early (~1976) Intel data catalog. For the 8008, the best is the mcs8 microcomputer set users manual. Someone on the list just found one in the last week or 2. I probably have a "condensed" data sheet from a Intel catalog as well. The mcs8 book is about 100 pages. The instruction set would be only 4 pages or so. I might have some data A few years ago I searched all over the place, not only Halted, James, ACP, and any other advertisers in early Byte magagines that might still exist, but the "obsolete ic" house resellers too. Remember the ads for "8008 +8 2102's"? I only found about 3 "tubes", but may not ever use them as wire wrapping 8 chips give only 256 bytes. How many do you want? Can't you find this stuff by the barrel and data sheets by the ream there in Si valley :-)? ..Like a west coast "Poly Pac's". No I don't expect to find a Mark 8 or Scelbi, so am moving slowly to building a 8008 system. I did finally find a copy of "Microcomputer Design" by Martin by interlibrary loan :). Abebooks, etc never found it. It is loaded with 8008 stuff with things like all timing, a 9 chip 8008 system, etc. They also sold the "Mike" series of microcomputer boards, but I have never seen one except pictures in early Byte's. I also tried to find Martin or his company (In Illinois), but no luck. By the way, searching, I found a rumor that Intel was going to come out with a support chip for all the control logic for the 8008. I have seen no indication they did, just went on to the 8080. dastar(a)siconic.com --- -Dave
