I'm curious as to what you'd be able to find. Like I said, I'm pretty sure
DEC never did an RK11-C inlay; the engineering drawings for the 19" indicator
panel (included in the RF11 engineering drawings:
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.

I am currently using kicad for the stuff from other PDP-8/omnibus
creators but I intensely dislike the user interface paradigm on kicad.
We use Altium at work and I have been thinking about using that.

I haven't priced anything out yet. My current project will have
reasonably large sized board but will be using DIN 41612 style

Ethan,
I completely agree with reducing the strip size.
One of my projects is a redesign of Oscar Vermilion's PiDP-8/I using
addressable LEDs. I was thinking of breaking the 88 LEDs into separate
strands based on function (step counter & Multiplier Quotient [17 LEDs],
accumulator and link

One of my zillions of projects is to redesign Oscar Vermilion's PdDP-8/I

I would use one core for SIMH (the PDP-8 simulator) and one core for the

A great lead-in to my story. I was working away on the RK11

Now *that* is a wonderfully obscure device. I wonder if any software for it
