It doesn’t need to be pin-compatible, although that would be nice.

27C256 – 27C256 256K EPROM Datasheet

Not an ‘answer’ per se, just an opinion: 27cc256 never used the 28C family. I’ve been using the pin DIP package. JohnMiles, could you elaborate? Could you let me know why you think a FPGA approach would be better and point me to any educational material? Perhaps the limited available time could be used more productively with modern hardware. I hope to inspire some to grad school. John Miles 3 5.

The instructions are read by a low-speed TTL computer they build. Can you tell me anything about it? Robustness to student wiring mistakes would be great.

I also don’t care about speed. The goal of my course, which is the introductory and only architecture course at a liberal arts college, is for students to understand all the way down to the gate level how computers work, not to directly prepare them for industry. I believe the 29Cxxx series is now mostly flash memory.

This question appears to be off-topic. 27f256

You could also try Jameco. I don’t think you’re doing your students any favors by getting epgom to build stuff out of series TTL in this day and age.

It is a little cheaper in price, and also in stock. Specifically, it should be reasonably priced, reliable, easily available and likely to remain so. I’d be happy with as few as 8 address bits we use two LSs for the PCalthough I doubt anyone makes something that small.

Ellen Spertus 2 9 There are still a few parallel flash 27256 available in DIP, e. There is also a 8Kx8 version of the same chip with a compatible pinout unused address lines are no connects.

Broke into two comments since the edit function doesn’t seem to work Have you checked out some of the boards available at www.

I like the Nexys2, personally, and the books by Haskell and Hanna look pretty good for bringing newbies up to speed. Instead, describe your situation and the specific problem you’re trying to solve.

However, it struck me that you must be spending a lot of time getting them to the point where they understand what they’re hooking up, and why. I don’t have experience with Epro.

What’s a good EEPROM replacement for a 27C/29C? – Electrical Engineering Stack Exchange

You didn’t say which package you are using, I assuming it is a pin DIP. They tend to be higher capacity than eeprom devices, so more address erom to tie but otherwise equivalent to eeprom for your purposes. The users who voted to close gave this specific reason: Home Questions Tags Users Unanswered.

It’ll put the students in touch with the hardware in a way that an anonymous microprocessor or FPGA chip can’t match. One more comment in the form of an actual answer: Would the 28C family be a good place to look? I find the hands-on work, including the debugging, to really get this information across to all levels of students.
