but it only has the standard character set that comes in it. There
is another socket that I believe might be for the MouseText set,
but I don't have it or know where to get it. Or, does that go into
the motherboard as a replacement rom? I would be happy to pay
someone for their time and effort if they know how this is done
and can supply me the necessary eprom/rom/info to do it. If you
have this knowledge and the time to help me out, then email me
and we'll work out a deal.

Thanks in advance.

"Computer Shopper", tells how to connect a 2764 EPROM in the
character generator socket. The 2764 can hold two complete
character sets, because it has twice the capacity of the 2732
normally in that socket. However, the socket has only 24 holes
and the 2764 has 28 pins! Don shows how to wire this up with a
socket adapter, and use a toggle switch to select either half."

The second ROM socket is for the secondary character set
(7x9 characters) for the Videx card. It was often used for
inverse characters to support VisiCalc, IIRC.

Thanks, and although this is quite true, it isn't auto-detectable.
You have to instill a keyboard command, AFAICT, to get the
secondary character set to be implemented.

Well, you certainly have to select the secondary font, which
can be done with a keyboard sequence, though it is usually
done through a software protocol.

I believe that there was an (obscure) software protocol for
determining whether the secondary font ROM was installed,
as well (and maybe even reading it).
