I think that the Phoenix 2. Some manufacturers occasionally let Vpp float, which was bad design practice, but it happened nonetheless. The users who voted to close gave this specific reason: If it doesn’t like your drive, then the problem’s hardware, not software. The damned thing still refuses to do 1. 29c2256

There must be something more ellegant that wouldn’t need any external hardware. Instead, describe your situation and the specific problem you’re trying to solve. If no, you may find that a standard 1.
K2, Sorry about the repeated thread hijacking, but I can’t seem to help myself! Maybe I could run some wires from my programmer TOP to the sockets.
There probably is–I’ve certainly done this with 28C64s on things such as disk controllers. I’d be happy with as few as 8 address bits we use two LSs for the PCalthough I doubt fatasheet makes something that small.
There’s a lot of good stuff in the 29C datasheet. I’ve been using the pin DIP package. Mine are new as well, and I can get other sizes if desired.
According to the schematic that I have, pin 1 is connected to pin 27 check this with an ohmmeter and labeled A Sorry Mike, It’s fixed now. It’ll put the students in touch with the hardware in a way that an anonymous microprocessor or FPGA chip can’t match.
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. That’s a you have?
Looking for 27SF256 or 29C256…
John Miles 3 5. That would be pretty cool, but I would need to be able to select between U18 or U They have a good price. Do ya think the 29c will work in place of the 27c?
He sells them in quantities of 10 for Even more interesting is to substitute a SRAM, write the contents and then do a warm boot. The bios works, buy the at still refuses to employ 1. Broke into two comments since the edit function doesn’t seem to work Have you checked out some of the boards available at www. My usual Maxim-IC doesn’t appear to carry them, that or i can’t find them, there are sites that MAY appear to carry them, but since i’m a student, i hope to use the free sample route.
If so, I’ve wasted a lot of time putting 27cs under the UV light for erasure. I’ll take a look at the schematics and see if anything looks good. I’ve thougt the same thing, but don’t know where to start.

Ellen Spertus 2 9 I haven’t determined if they are connected to anything else. They tend to be higher capacity than eeprom devices, so more address lines to tie but otherwise equivalent to eeprom for your purposes. Not much luck though, any suggestions on who still carries them? That doesn’t surprise me. Thanks for looking into the matter! I’ll check and see if I can’t give a better answer. Easy enough to work up a simple adapter.
Assuming he has the particular type you need I think I’d pay the extra. I’ve never used the 28C family. I think that stock controller hates 1.
