You forgot one vital component: the switches. The 7101 and 7103 series
switches used in the IMSAI front panel are still available new from C&K,
at $5-$6 each. They start adding up fast! And cost of a full-length (22-
slot) backplane would come to around $150-$200 these days. (Though you
could easily argue that now that we have memory boards larger than 4kbytes
you don't need all those slots, all of my real IMSAI's have 22-slot

A year or so ago I looked at what it would cost to make my "TIMSAI" IMSAI
clone into a commercial product. Street price, I calculated, would be about
$2000, and most of that was in the metalworking. There was only about $30
in semiconductors in the whole unit (and that included 256K SRAM and an
IDE/floppy controller).
