The Penguin of Evil

Can anyone help identify a bunch of stuff from Selectronc (presumably the French Selectronic) from the 1990s

There's an I/O expander with a 31pin a side edge connector, and 3 i2c cards using RJ11 style connectors that are EEPROM 256 octets, DTMF generator, I/O 8bit in + led visualisation.

@etchedpixels Could it be an ISA connector? What does the instruction say?

@tk That one does appear to be an ISA card without the usual edges yes, and the documentation agrees. The others are much stranger and have example BASIC apps for a BASIC that
- supports hex as 02h etc
- has an IIC keyword
- has a POP keyword

@etchedpixels could be a lot of things by this description? :) Do you have pictures, names of the chips or the example programs in question?

@etchedpixels the number 894005 on the pcb points me to https://www.gods69.com/download/REVUES_Radio_Plans/1989/Radio%20Plans%20503%20-%20octobre%201989.pdf page 57, an ad from Selectronic saying that it's a "mini i/o board for PC, 24 io lines" and the number is from the Elektor magazine catalogue, and it was published there in issues 133 and 134.

@pulkomandy I'd never considered these might be Elektor project boards. Bangs head on wall.

The board in that package looks like an Elektor board. It's only them that used those style pads for ICs. That might help you
