Tempustech F82C100 card

[per]

Recently I got hold of this interesting card. It sports a V20, and by the chipset it should be a PC compatible. However, trying it out this turned out more interesting than expected.

Mainly, it turns out the ROM is not a BIOS, but features some kind of firmware for some embedded application. It's the first time I've come over something like this, as most other embedded PC solutions I've come across often run its firmware from some lightweight DOS drive over a fully fledged PC-compatible BIOS.

Have anyone seen anything like this before?

Where I find TempusTech mentioned is in connection with old Paretta web press inkers. Apparently a passive backplane setup.

There's a short discussion of this board's twin here

This came out of an old liquid tensiometer, and yeah passive backplane indeed. It's a pretty neat lightweight form-factor if you just need to throw a temporary XT-configuration together for whatever reason.

Thanks for the link! I was a little surprised to see the BIOS available as well, they really did some nice work there.
