The serial interface from Schneider contains a great chip, it's the: Z80-STI / MK3801
However, sometimes this chip breaks... what to do now?
At ebay you find them between 9 an 90 Euros.... a bit expensive, right?
Now here you get my offer for 4 Euros each.
And if you're a user of FutureOS you can have the Z80-STI / MK3801 for 3 Euros each.
I'm willing to sell up to 3 pieces per person (to save shipping costs).
Time to fix your Schneider serial interface!
