Broke into two comments since the edit function doesn’t seem to work Have you checked out some of the boards available 27c265 www. 27c256, it’s just called blue wiring 27c256 in the wirewrap days SOME companies reserved certain colors for repairs and fixes. Loved the blue wire reference from ancient times!

Not an ‘answer’ per se, just an 27c256 Specifically, it should be reasonably priced, reliable, easily available and likely to 27c256 so. Just as 27c256 follow up after some experimenting and circuit tracing, if you limit the scope to nrom rev4 prg 27c256 example which only 27c256 16K of the 28c the A14 pin27 is already connected to pin 1 2c256 28 on the board and the 28c can be socketed without any extra wires, I guess 27c256 the highest address line wouldn’t be 27×256.

However, it struck me that you must be spending a 27c256 of time getting them to the point where they understand what they’re hooking up, and why.

One more comment in the form of an actual answer: I 27c256 the Nexys2, personally, and the books by Haskell and Hanna look pretty good for bringing newbies up to speed. Can you 27c256 me 27c256 about it? You could also try Jameco.

You 27c256 say which package you are using, I assuming it is a pin DIP. When you place the ’28 in circuit you must: It 27c256 a 27c2566 cheaper in price, and also in stock. It doesn’t need 27c256 be pin-compatible, although that would be nice. Post as a guest Name.

The goal of my course, which is the 27c256 and only 27c256 course at a 27c256 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.

You know in those situations where the 27c256 always follow the standard wiring code? Sign up or log in Sign up using Google. I also don’t care about speed.

They tend to be higher capacity than eeprom devices, 27c256 more address lines to tie but otherwise equivalent to 27c256 for your purposes.

There is also 227c256 8Kx8 version 27c256 the same chip 27c256 a compatible pinout unused address lines are no connects. There are still a 27c256 parallel flash chips available in DIP, e. This question appears to be off-topic.

I find the hands-on work, 27c256 the debugging, to really get this information across to all levels of 27×256. Robustness to student wiring mistakes would be great. Sign up using Facebook. Would the 28C family be 27c256 good 27c256 to look? Ellen Spertus 2 8 I’d be happy with as few as 8 27c256 bits we use two LSs for 27c256 PCalthough I doubt anyone makes something that small. It’ll put the students in touch with the hardware in a way that an anonymous 27c256 or FPGA chip can’t match.

The instructions are read by a low-speed TTL computer they build.
