For the longest time, the TMS 9900 didn't appear in anything one could
consider a reasonable computer. There was one model I saw at a colleagues
home which had expansion capability, but he often complained that cards for
interesting applications, like mass storage, etc, were not available. I
didn't pursue it and so I believe(d) it to be true. I saw one ad for an
SC/MP, in '77, but that one was a homebrewed model. Other than that, it was
not of much interest here. Was that not the case in Germany? The processor
was still in National's data book, but I really wasn't then and am not now
of any operating system or application software for it. I don't believe I
ever saw a real SC/MP based computer.
