H'm, the voltage switch modification is a bit messy, isn't it?

That isn't the Ground Control board, I'm afraid, but give the ROM a try
and see if it'll work anyway:

http://jasper.org.uk/roms4.zip
http://jasper.org.uk/roms7.zip

these are disc images.  The boot menu assumes you will want to load the
ROM image into sideways RAM at socket &F.  (Change line 70 in $.MCODE to
suit, or use your own ROM-image-into-sideways RAM loader)

roms7 contains a later version of the Uviprom software (v2.1) than
roms4, but both work with the Ground Control programmer.  *H.U. will get
you help, but in brief:

*TEST checks that a ROM is blank
*READ <filename> reads a ROM image from disc into the memory buffer
*BLOW blows a ROM image from memory into the programmer
*COMP checks whether the ROM just blown has the same contents as the
disc image (in other words, whether the ROM burned OK or not)

I can't remember what *UPPER and *LOWER do. I *think* this might be to
blow a 32k EPROM as two separate 16k halves if your programmer supports
it.  The same software was used with a number of different
manufacturer's EPROM programmers, so there is a chance it may work with
the one you have there.
