The only two historical references I see on forum.world.st are from 2006 &
2010.

and they have some link rot.

I'd guess your best approach would be to get something working in pure C,
and then provide functions that Pharo can call via FFI.

Alternatively, from personal experience when I used to hoard such old
parts, it may be
economic use of your time to throw the old board away, and use a modern
microcontroller.
What you learn could facilitate more opportunities, and this stuff just
keeps getting cheaper,
while parallel ports get more expensive while knowledge of them keeps
getting less relevant.

Maybe a $20 ESP32 with 18 ADC channels + MQTT

Or use a Raspberry Pi...

that can run Pharo directly, but I'm not sure what access to pins is
currently available.
Again you could go the FFI route, or someone else might advise.
