But that does bring up the unspoken requirement that a modern digital
version of such a device has to be capable of withstanding huge
longitudinal over voltages from nearby lightning strikes and the EMP
associated which means power strip types of varistors to absorbed them, and
absolutely un-crashable, fully capable of year+ uptimes. Such code can be
written, I've done it, without benefit of watchdogs, and some of my code
has been in continuous use at the broadcast facility I wrote it for, for
open ended periods that have approached 2 decades with only hardware
failures and repairs thereof interrupting it. One was written in 1802 hex
code, and one written in Basic09 for the os9 operating system on TRS-80
But my little helper scripts I use here, today, were all done in bash & I
haven't quite managed to make my kmail helper immune to out of order
Am I prolonging the agony of old age? Probably, but no one knows better
than I that I am not the coder I was 20 years ago on far simpler hardware
than this quad core phenom picking up my keystrokes now. Besides, I have
waaaayyyy to many interests, including making sawdust and furniture in my
waneing years. Currently working on a gunstock for a black powder rifle,
one that hasn't been seen on such primitive weapons yet, modern thumbhole
style, my 5th such project in the 50 years since the first one.

Pretty much, the i/o itself will be mostly cut & paste from existing
designs. The art in box metal will likely be limited to the cutting and
bending/punching for connectors, a decent paint job (black is not a
requirement, but a euphemism) and silk screening or engraving the labels.
Connector costs will be perhaps 15% of out of pocket once the design is
committed to production.
That sort of hardware can be farmed out lots cheaper than you can set
yourself up to do it, see the back pages of most any issue of Circuit
Cellar for a choice of those.
