Let's see how the 32 bit version works!

Thanks to niece Danielle for consultation.

Definitely protect against remote access to private keys. How strong does the protection against local access need to be?

But this potentially exposes the hardware to remote access via the USB I/F when connected.

Using "disk drive" IO introduces air gap - remote access impossible. Increases attack surface via filesystem manipulation. But use signed requests, so attacks would have to be insider requests.

Found in SCZ. Thought it was in SJ.

Unlocks encrypted filesystem. Maybe not needed. See below.

Only need ONE button, and a pass/fail LED. Hardware will never go EOL (Thanks Elena!). Susceptible to remote audio recording of PIN button noise, which could be overcome by using 2FA. Again - what am I protecting against?

May be more straightforward.

Have more than enough laying around.

Also have more than enough. Old enough hardware can drive the display directly off the parallel port.

For sensitive material only.

One should not be disappointed that a guitar can't sound like a flute.

Create verilog models for 2903/2910 and verify against hardware?

…Along with standard 8 bit loader

6809 1000ns maximum cycle time too short

Reverse engineered some of a mostly fully built development board with one part missing. As near as I can tell, that one part is some sort of programmable address decoder with a pinout that does not correspond to any part I can find. Kind of like a GAL but with inputs on top and outputs on bottom (as opposed to left and right in a standard GAL). I have no idea what the provenance of this board is and if it ever worked.

No. Existing library is fine.

Full debug fails - not enough disk or memory.

Good excuse for floating point ALU design. Try posit format?

May be useful for handbuilt and rare systems (DMX1000?).
