I have the sad carcass of a possibly restorable 990/4 CPU,
sold as a mini, but based on the TMS9900 and not terribly
well-built. (The front panel switches are calculator buttions
using the same collapsing dome technology as the old TI-30
calculator I used to own, and have gone bad in the same way
the calculator keys did.)

I don't recognize these boards from the numbers, but I was
hoping they would either match this machine as spares, or
perhaps would serve as bait to bring a nicer 990 my way. ;)
Architecturally, the TI990/TMS9900 is interesting, but
the TI99/A home computer was an abominably bad design and
I can't bring myself to own one.  I mostly avoid micros,
but I do have a weakness for blinkenlights front panels
wherever they are found. :)
