Imsai before 76

<Almost let an error slip by there, the IMSAI dates to the end of 1975, <November I think, the first ad was in the December 75 issue of Popular <Electronics, along with the Processor Tech VDM-1 video board. We had <one running in the lab by Xmas 75, the short motherboard (12 slot, IMSAI <dropped it early in 76), 8080 CPU and 4K static ram (1K installed), all <for only $429 in kit form. Which is why I said "more like 76". actually I have the Jan 1975 PE with the Altair on the fron which predated the IMSAI. That summer IMSAI announced the IMSAI. FYI by December 76 I would have over 11 months of operational experience with my altair... and wishing I'd gotten a SOL or IMSAI! Speaking of IMSAI I have a IMP-48 (8035 cpu) which was also made by IMSAI as a SBC for control apps and low cost computing. I'm seriously looking for a manual. I've had this board since 81 sans book (It works and I can run it, even preserved the eprom!). The dates on the parts suggest late 78 manufacture. Allison
