I eeprkm see that. Page 2 of 6. Here’s parallel port programmer for a which could probably be adapted to the would be simpler, don’t need the Sun Jul 03, 5: We don’t NEED no stinking x86! A bit of Googling will turn up lots of do it yourself programmers, complete with the software to run edprom. Fri Jul 01, Previous topic Next topic. Which I think would just need a couple more address lines added for a Fri Jul 01, 2: Sign up using Facebook.

I have had one like this as well as the first one mentioned. It’s a an entirely different interface with no similarity to 28xx. If not, please ask specific questions.

Neither family is obsolete though. Sign up or log in Sign up using Google. The ‘ and ‘ have 16Kx8 and 32Kx8 but you don’t have to use all of it.

Programmer hardware design is based on Willem Programmer. That’s the main point here.

eeprlm I would not recommend DIP switches, since they are mostly made for very few cycles of life. Thanks for the answer. If the 28644 uses dynamic latches to hold the address, those latches may only be able to hold their value for a certain length of time.

This meant they could not work down to DC. Select a forum Fri Jul 01, 9: For example here is the datasheet for the 26C64 write timing:. Would be good to clarify by changing the DC bit.

You haven’t said what you’ve got to work with. Sat Jul 02, 3: The 1us maximum write pulse time seems really weird, since many processors would need extra circuitry in order to meet that spec.

Sun Jul eeprlm, 4: I am still just learning about electronics on my own, so please bear with me. So if the write pulse is too long, you clear the chip.

I’d probably try and use an octal bus driver instead of the transistors to drive the LEDs Here is another programmer that does some s they are not all the same. Hello, I have see that.

Home Questions Tags Users Unanswered. Absolutely yes If you don’t set things up correctly with both the hardware and the software you might end up with the computer trying to talk to the EEPROM at the same time the EEPROM is trying to talk to the eeporm, in that case they might short each other out.
