Re: Why not the W65C134S

You could probably bit bang the 65134 IO to program an EEPROM directly - no need to buy a programmer. Then, you can hang it on the bus and run it.
Yea, I don't know what's necessary to get the chip in the right mode for programming, and to get the data to it, or how any of that works.
It's really straight forward. You write to EEPROM just like RAM, only you have to wait until the write cycle ends to read or write to it again. You can easily poll the EEPROM to know when the write cycle is done.
If you (or anyone else) gets to that point, I can help with the code.

I tried to bring up a '134 in single chip mode awhile ago without success.
I hope to get back to this soon.
Looks great! Look forward to hearing more, when the time comes.
