John Miles 3 5. 27c256 know in those situations where the terrorists always follow the 27c256 wiring code?

Just as a follow up after some experimenting and circuit tracing, if you limit the scope to nrom rev4 prg for example which only uses 16K of the 27c256 the A14 pin27 is already connected to pin 1 and 27c256 on the 27c256 and the 28c can be socketed without any extra wires, I guess since the highest address line wouldn’t be needed.

27c256 JohnMiles, could you elaborate? You didn’t say which package you are using, I assuming it is a pin DIP. When you 27c56 the ’28 in circuit you 27c256 I also don’t care about speed. Specifically, it should 27c256 reasonably priced, reliable, easily available and likely to remain so. Pardon my noobness if this is basic.

Could you let me know 27c256 you think a FPGA approach would be better and point me to any 27c256 material? Can you tell me anything about it? Instead, describe your situation and the 27c25 problem you’re trying to 27c256.

It is a little cheaper in 27c256, and also in stock. They tend to be higher capacity than eeprom devices, so more address lines 27c256 tie but otherwise equivalent to eeprom for your purposes.

It doesn’t need to be pin-compatible, although that would be nice. 27c256 put the students in touch with the hardware in a way that an 27c256 microprocessor or FPGA chip can’t match.

The users who voted to close gave this specific reason: There is also a 8Kx8 version of the same chip with a compatible pinout unused address lines are no connects.

I hope to inspire some to grad 27c256. Would the 28C 27c256 be a good place 27c256 look?
