I got a board today containing these chips,
Any guess what they are for? My quick internet search didn't get results:-/

Thanks, Michael

Thanks for the fast reply:-)

I paid 20 Euro, a good price or too much?

The chips are in very good shape so the price is ok!
How much did you pay for the 4004-board? Wink
