[sdiy] patch matrix

[ian]

Hi all,
I have been listening to the list for a while now, and have squirreled
away a lot of interesting articles for future reference! This is a great
list with a lot of interesting ideas floating about.
I am about to start out on my first DIY project - building myself a Maplin
5600S (also known as the ETI 4600). Its a really interesting looking
synth, but I'm having a bit of trouble finding the 30x30 (or perhaps a
little bigger to allow for mods) patchpoint matrix it requires. Looking at
the construction manual, there is a picture of the back of the patchpoint
matrix, complete with manufacturers name. I can't make it out very well,
but it seems to be 'seolectro'. Anyway, I was hoping someone out there
might be able to point me at a supplier. Things I've had a look at include
the Analogue Solutions matrix (too small), the EMS matrix (too small), and
the Info-Lite matrices somebody on here found (too big or too small!).
Googling didn't come up with anything either. Any suggestions gratefully
received!
Thanks,
Ian
