Do you have an 80C51 CPU or a CPU with a different number but in that same family? AFAIK, an 80C51 was a mask ROMed version of the 80C31. I know that later devices used OTPROM or EPROM or flash, but AFAIK they had distinguishing part numbers, eg 87C51 or 89C51.

You got me. The chip is an Intel 87C51FA-1 which does contain 8K onetime EPROM. I had labeled the origional as 80C51, and had to dig out my reading glasses to check the unprogrammed spares. Thanks for catching this.

Be aware that the 87C51 includes lock bits that prevent reading of the code after programming, as well as an optional encryption array, so it may not be possible to clone your existing chip.

I origionally programmed the chip, so that should not be a problem.

(I've been out of the loop too long. I hope some of these still exist.)

1. Ask, or check the notice board at Vetco (Bellevue/Redmond)
2. ditto Alphatronics (Tukwila)
3. Connect with the Seattle Robotics crowd

Both of these last two used to be really active on Usenet and the web. Looks like they may have imploded?

There's plenty of cheap programmers on ebay last time I looked.

Thanks for the clue. I should have looked there first. That's where I bought the

I just ordered one from McuMall via ebay. $32 + $10 shipping + $15 for the 87C51 adapter.

It arrived 2 days after I ordered it. Good fast standard delivery for a reasonable cost. Thanks everyone for the help.
