hi all, because i need to replace aim65 eprom, i'm looking around to get an eprom programmer but must of are working with windows dedicated software, closed software.

of course i've in office some windows based pc, and maybe some with parallel port (i hope!), but i prefer a more flexible solution if possible.

any suggestion?

thank you!

Hi, I built Mario's Arduino based EEPROM programmer: http://www.ichbinzustaendig.de/dev/meeprommer

His software is either Java or Python based and should work on the Mac. I had some problems getting it to work on 64 bit Windows because of librxtx incompatibility and wrote my own C# loader.

I also built my own programmer:

http://aslak3.blogspot.co.uk/2013/04/ee ... d-and.html

It uses an ATMega8 AVR with some counters and can be built on breadboard if desired. Software running on the host is a trivial C program, which is of course freely available on github. In fact the protocol is so simple any language could be used.

I can second the Meepromer, it worked fine with OS X (had to canibalize the RAM from the MacBook I was working with so can't fire it up at the moment).

sorry guys but i need an EPROM not EEprom programmer, maybe also voltages are different? (2732 and 2532 chips)
as you can image, i'm not an expert but i understand basic electronic and surely i can build up something in a breadboard.

anyway thank you for your help.

Have a look at the Willem programmer (see ebay), there is Linux software. http://sourceforge.net/projects/geepro/ It does require a parallel port, a rare device lately.

These seem like they might fit the bill: http://www.batronix.com/shop/programmer/BX32/eprom-programmer.html.

The programming software is available for Windows, Linux and OS X.

Nice supported programmer!

But on the downlaod page I read:

Note: The OS X version contains known bugs and unsolved performance issues.
Please install this version only for testing purposes!

That's disappointing... even worse, the OS X version requires the "Mono" framework, which indicates that it's heavily based on (or almost identical to) the Windows version.

My programmer's BoM is roughly as follows. Prices are in UK pounds, with parts sourced from ebay

* ATMEGA8-16U 1.29
* USBISP programmer 1.66 (if you don't already have one)
* IDC 10 way box header (x10, you only need 1 for the programmer) 0.99
* USB to TTL serial converter 1.05
* 74HC590 8 bit counter x2 2.77
* DIP28 ZIF socket (x2 but only need 1) 0.99

Plus the usual assortment of a couple of LEDs and a PCB button, but those are really optional.

I've only made a programmer for the EEPROM I use, a (AT)28C256. But the design should be adaptable to any 5V programmable parallel EEPROM up to 64KByte in size.

Firmware for the AVR has only ever been built with avr-gcc, but this should be available for OS X. Client code is a trivial POSIX C program, which runs on Linux but should work on OS X if called with the appropriate serial device name.

If you want any more info, let me know. I'm in the same boat as you BTW. I wanted an OS X/Linux friendly programmer and didn't want to spend much money, so I built my own. I still use it a couple of times a month, though since my micro is self-updateable it's less frequently used then it used to be.
