I got mine from Mouser Electronics. Great service and they'll sell you a
single component using a credit card order. It cost me ~$20 with
shipping. That seems expensive, but it wasn't a bad price to resurrect a
free computer. ;)
I got mine for an old SS2. I don't have the part number handy right now,
but I found it on a FAQ on the internet. The FAQ also describes exactly
how to program it after replacing the chip. Let me know if you can't
find the FAQ, and I'll dig around for the URL.
