The instructions are read by a low-speed TTL computer they build. I hope to inspire some to grad school.

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’d be happy with as few as 8 address bits we use two LSs for 27c2256 PCalthough I doubt anyone makes something that small.

Instead, describe your situation eprlm 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’ve been using the pin DIP package. It is a little cheaper in price, and also in stock. Perhaps the limited available time could be used more productively with modern hardware.

I like the Nexys2, personally, and the books by Haskell and Hanna look pretty good for bringing newbies up to speed. Robustness to student wiring mistakes would be great.

Ellen Spertus 2 9 I don’t have experience with FPGAs. The users who voted to close gave this specific reason: I find the hands-on work, including eeprom debugging, to really get this information across to all levels of students. There are still a few parallel flash chips available in DIP, e.

eproom JohnMiles, could you elaborate? I’ve never used the 28C family. You didn’t say which package you are using, I assuming it is a pin DIP.

One more comment in the form of an actual answer: This question appears to be off-topic. Specifically, it should be reasonably priced, reliable, easily available and likely to remain so.

Would the 28C family be a good place to look? There is also a 8Kx8 version of the same chip with a compatible pinout unused address lines are no connects.

It doesn’t need to be pin-compatible, although that would be nice. I believe the 29Cxxx series is now mostly flash memory. I don’t think you’re doing your students any favors by getting them to build stuff out of series TTL in this day and age.

They tend to be higher capacity than eeprom devices, so more address lines to tie but otherwise equivalent to eeprom for your purposes.

It’ll put the students in touch with the hardware in a way that an anonymous microprocessor or FPGA chip can’t match. Not an ‘answer’ per se, just an opinion: Could you let me know why you think a FPGA approach would be better and point me to any educational material? I also don’t care about speed.
