Want to set up the Apple //e and use this with putty.exe to watch my
crypto miners for a hoot :)
(what can I say..I'm bored.....can do this with a pi....why not an apple
II?)
anyway, just have not heard of any other runs on this ..so was curious

If you're up for a little bit of hardware assembly, I designed a workalike board a while back. It's not perfect (probably should redesign it so the Raspberry Pi doesn't bump into the 6551), but it works.
You can order bare PCBs from OSH Park...current pricing looks like $38.55
for three:

I only assembled one of mine. If I knew where the remaining blank boards were hiding, I'd offer them for sale.
gEDA design files (schematic and PCB) are up on GitLab:
https://gitlab.com/salfter/A2RPi
They depend on additional symbols and footprints:

I don't have a BOM on hand...currently reinstalling gEDA so I can look up
the component values. One detail I do recall is that you probably want to use a NOS 6551, not the updated part that WDC is selling. (I assembled mine with a Rockwell 6551 with an early-'80s date code, purchased from an eBay seller.) The other chip is probably a 74[LS|HCT]245, the crystal is the
usual 1.8432 MHz (there's also a build option to use a Raspberry Pi GPIO pin as the clock source, which is what the Apple II Pi uses), and then there are a small handful of capacitors and resistors.

Likely beyond my meager capabilities to pull that off. Thanks anyway.
You'd think there would be a market for this...if for no other reason to
have a PI up where you APPLE II sits on your counter for other uses.....
Any idea when another batch of these will be available?
