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.

This question appears to be off-topic. I’ve been using the pin DIP package. Broke into two comments since the edit function doesn’t seem to work Have you checked out some of the boards epro at www.

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.

The users who voted to close gave this specific reason: The instructions are read by a low-speed TTL computer they build. Perhaps the limited available time could be used more productively with modern hardware. 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. I also don’t care about speed. I find the hands-on work, including the debugging, to really get this information across to all levels of students.

I’ve never used the 28C family.

You could also try Jameco. Can you tell me anything about it? Ellen Spertus 2 epom I hope to inspire some to grad school. 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.

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

Could you let me know why you think a FPGA approach would be better and point me to any educational material? It doesn’t need to be pin-compatible, although that would be nice.

John Miles 3 5. You didn’t say which package you are using, I assuming it is a pin DIP. 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. Specifically, it should be reasonably priced, reliable, easily available and likely to remain so.

JohnMiles, could you elaborate?

Instead, describe your situation and the specific problem you’re trying to solve. Not an ‘answer’ per se, just an opinion: Home Questions Tags Users Unanswered. It is a little cheaper in price, and also in stock.

One more comment in the form of an actual answer: There are still a few parallel flash chips available in DIP, e. 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 eeprom.

I don’t have experience with FPGAs. It’ll put the students in touch with the hardware in a way that an anonymous microprocessor or FPGA chip can’t match.

I believe the 29Cxxx series is now mostly flash memory.
