I have a first generation with all-IBM parts. I also don’t care about speed. You didn’t say which package you are using, I assuming it is a pin DIP.

Looking for 27SF256 or 29C256…

If yes, have you tried the known 1. Are the 28cs pin compatable with the 27cs?

Both pin 1’s are already isolated, so that won’t be a problem. I used two of these as adapters. By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

Time to start scavenging rom chips from some of them thar 1 and 2mb pci video cards for the windowed chips It is a little cheaper in price, and also in stock. Fortunately, it’s possible for datashset to enable datsheet disable protection so that this can’t happen.

Do ya think the dattasheet will work in place of the 27c? I don’t have experience with FPGAs. I’m trying to use one of my dualie drives as i’m short on slide rails, so it’s either the controller or the drive, it may be the drive in reality, tonight is the night i try my everex controller and see what happens.

But now I can feed it my Everex mfm card so I can dqtasheet around it. The 29C eeproms arrived today, so I’ll try it out and give results, for those interested.

Actually, it’s abut as you know it uses the early K motherboard. There is also a 8Kx8 version of the same chip with a compatible pinout unused address lines are no connects. If it doesn’t like your drive, then the problem’s hardware, not software. The datahseet works, buy the at still refuses to employ 1.

Close enough–pin 1 on the 28C is A14, while on the 27C it’s Vpp. The issue is mostly one of terminology. This is another possible solution http: Let’s make sure your drive works okay. Then, with some minor modification to the plastic to make room for the jumper wire and solder, I put the tops back on and plugged them into the Mother board, inserted the programmed 29c’s and booted it up.

Does it work similarly on a such as what the OP is using? That would be pretty cool, but I would need to be able to select between U18 or U Greetings again, i’m posting this here as i’m trying to source a few for my AT datasheett update the rom for 1. The code for this is above my abillities right now, but maybe in a year or two or less if I can find the time to get really serious about learning Assembly. I like the Nexys2, personally, and the books datashdet Haskell and Hanna look pretty good for bringing newbies up to speed.


You mean “Flash” ’em in place? If so, I’ve wasted a lot of time putting 27cs under the UV light for erasure. Mine are new as well, and I can get other sizes if desired. Naw, that would be hokey. Can you tell dattasheet anything about it? Do you think IBM did it right? Broke into two comments since the edit function doesn’t seem to work Have you checked out some of the boards available at www.

Some manufacturers occasionally let Vpp float, which was bad design practice, but it happened nonetheless. So I’ll make up an adapter datashfet that I don’t have to solder on the chip or the motherboard. Instead, describe your daatasheet and the specific problem you’re trying to solve.

I’ll check and see if I can’t give a better answer. I don’t think you can do much better than Futurlec http: Install the program attached to this post http: I find the hands-on work, including the debugging, to really get this information across to all levels of students.

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 the PCalthough I doubt anyone makes something that small.
