The first thing I would suggest is to change to 3.50d. TAPR has ROMs and the
image is readily available if you can program EPROMs.

Also check the battery to see if is still alive. If you need parts let me
know as I still have most everything in the kits.

After making these changes let me know your results.

One more addition, if you order a new EPROM, make sure you order the proper 
one depending upon whether your box has been upgraded - Basic or Turbo with 
80C320 and 22 MHz clock.
