Hello all

Interesting discussion and subject.
I'm working on something related to this, I want to use an SFX Sound
Expander as a stand alone synth, with buttons, knobs and all that stuff.
In the longer term, it would be great if something new could be written for
the C64, as lets face it, the software is a bit basic and crude.

I got that program working in Vice, no problem at all, except rename it to a
.prg from a .txt, haven't tried it on a real C64 yet, maybe later today.

I own 4 of these carts and three full sized keyboards so am familiar with
the "something your wife wants to throw away" thing.  This just motivates me
more to complete what I've started.
The price of these things has risen over the last couple of years, but they
are quite common still.

It is correct that they came with a 3256.  One of my 4 carts is a bit
crunchy in sound so did look at replacing the chip with a 3812. But at the
moment that one is used for testing and development.

There is plenty of documentation for the device and most of the parts are
still obtainable, so a DIY clone shouldn't be too hard to build.  I am more
of a hardware person, so if anyone needs some help on this I'd be happy to
oblige.

Regards to all.
