You could hack a USBASP Atmel based programmer into a controller for

An old yardsale junker with 98SE or newer would run it.
Yep -- yet another system to isolate from the net. :-)
After I find a place to put that extra computer. I really like
sitting here with the keyboard of my Sun Blade 2000 in my lap typing
away. Windows doesn't do well with remote logins, though it sort of
works with VNC on both systems -- except that both the remote and local
keyboards are talking to the same process. A real pain if someone else
comes up to the Windows box -- or even if a cat hops on the keyboard.
You would only need it to program the chips. It doesn't have to be
on to run the boards. All they need is +5V after they are programmed.
The TI and the USBASP are both availible for under $5 each. The USBASP
has a small Atemel MPU on board, with a USB core loaded to allow it to
be reprogrammed. A second board is used to reprogram it. Here is a
link to midfying & programming the boards:

I think that I'll ask you for this again after the shop and
house are back together. I don't think that I have anyplace to save
this information (other than my saved copies of most of the newsgroup
articles which I actually read). The whole shop and house are going to
be in a constant state of flux until full recovery from the fire. The
shop has to be totally emptied, machines cleaned, relubed, and analyzed
after removal, all drywall pulled out of the shop, wiring checked, and
everything which survived goes back in.
*While* this is happening in the garage, our very cluttered
house has to be cleaned and partially packed up and stored outside the
house, while the walls are cleaned of the smoke, and re-painted.
This while a HEPA filter unit is cleaning the air in our
bedroom. (And we will have to move to the spare bedroom while the main
one is cleaned and painted.)
So really -- any projects are on hold until all of this is done.
Thanks,
DoN.
