Also, when the tapes arrive, are there recommendations in case their
drive belts are gone?
You can 3D-print replacements.
Use Innoflex filament, 100% fill-in and the following OpenScad formula :
module ring(d1,d2,w)
{
difference()
{ cylinder( w, d1/2, d1/2, $fn=230);
cylinder(
I have seen both upper and lower...if you fish through you can find what

I would be interested in an inlay - I have an RK11-C, but no indicator
panel.
Also, if someone (else, presumably) does up a replica of the indicator
panel board (perhaps with the option to use LEDs, with some resistor
packs that could be bypassed for lamps), I'd be interested in that, too.
Board cost depends on quantity, the more you have made, the lower the
per board cost.
PCBCart.com charges a "tooling" charge for a new design. They do look
over the designs carefully and reorders don't incur that charge.
To get an idea, I had a run of Joerg Hoppe's DEC Flip-Chip Extender
I've used PCBCart.com to have thousands of boards produced. Mostly with
gold fingers
They've done a good job with the boards, though they're mostly two-layer
and not overly complicated.
You just tell them how many gold fingers you want (and if you get it
wrong, their design check will
If anyone needs a backplane or two please contact me off list.
