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. Jack
