I have a large number of unused 8255 programmable peripheral interface ICs that will be binned if I can't find anyone who wants them. You'll have to take the whole lot (about 30 tubes with 10 chips in each), and you'll need to pick them up from Ormond Vic 3204 during business hours.
I didn't look at every tube, but most seem to be Mitsubishi M5L8255AP-5
In the tube I'm looking at right now, the chips have a manufacturing code of 827107 printed on them. They can't possibly be from 1982, so I'm not sure how to read that code as a date.
Does anyone want them?
