I purchased two TM500 extenders and four 7K extenders from John. I
am building the TM500 extenders now. The PWBs are of very good
quality and John has done a very good job with supplying the kits.
If you need an extender for either of these instrument types, I'd
recommend that you get in on the next buy, assuming John does
another.
Cheers,

I have plenty of TM500 cards for sale as kits, but I
will also sell a card set, no connector,
to make a plug with, no wires, shipped in a flat
envelope for $13.
