I am in a need of getting an EPROM programmed and possibly getting the contents of an other EPROM read. I don't have a programmer of my own so I would need to outsource this task or find a cheap programmer. Is the Willem the cheapest around or are there cheaper alernatives? What about DIY?
a Willem is cheap, and probably one of the cheapest, but can also be a pain from time to time.
and cheap gets expensive when you need different eproms programmed/read etc..
I have a Willem, and the 16bit addon.. and the addon was 2x the price on the willem programmer, which I got _really_ cheap on the evil bay.
when first using the programmer, I actually killed off some roms :-/ a GVP and a Malibu.
so please be careful and test it before reading.
(did I mention mine was cheap ?)
I may have to get the Willem, if I can't come up with another solution. There is on problem with the Willem though: it needs a parallel port and currently my only computers with parallel ports are Amigas.
Btw, if you suspect a ROM to be faulty, can the contents still be read from it or is it utterly unreadable?
Check out this card you might find them around your area..Quote:

Chris :coffee:
This really does depend on "how" the device is faulty, if it is in the programming of the cells - then reading should be okay -Quote:

As Monty would say:
"its beeding demised.... it is an ex-eprom/parrot thing and the only reason it was in the socket was becasue some one nailed it there...."
- and you wont need to go to Bolton to find that out either.
I believe that TheCorfiot managed to get hold of a very good and cheap 16bit EEPROM programming solution, hopefully he will be on here in a bit to tell you more.
I cannot say too much as my Willem 4.5 + 16bit module + a crap load of adapters was about £70, my Genus 540 EEPROM/FLASH / 74xIC Tester / GAL programmer was again another £55, my JTAG, TSOP and my Other 8Bit programmer - Another £50
I like my programmers.... I am on the hunt for a PAL programmer so if anyone can recomend one I would be cuffed =D
I would love to get a programmer that will do Commodore 64/128/Amiga chips. Unfortunately, I don't have a clue when it comes to EEPROM burners. I've heard of Willem in the past, but I don't know which makes, models, etc will work. If anyone can point to specific models, that would be great. :D
Perhaps this thread could be a good place for programmer reviews.
Take care,
Heather
Same here..
When I needed one a bit ago, I started to get into it because I thought of all the things I could eventually do with it...
Then I started looking and saw that this model would do X, but only Y if you bought Z. And even then, maybe not.. But that model would do X and Y, although maybe not W..
Then I found someone to burn one for me, which was OK, but I still wouldn't mind playing with one myself. I've got enough old machines (8 and 16 bit) that I can think of several uses. :-)
I think some reviews/guidelines would be a great idea!!

@Zetr0:
The ROM is a 27256 one and the pin 22 or /oe is on constant low, when it should be clocking. Kaputt?
The cheapest solution is a bread board with a power supply and programing it Bit by Bit. Long, tedious and very boring, but it can be done with no e-prom burner. of course you will have to do it in binary etc. it is not fun, but it is cheap.
@SDG The basic roms in the C64/128 can be programmed using the regular willem (36pin/8bit)
the roms/kickstarts in the amigas needs a 16bit adapter you put on top of the 36pin zif socket
(the zif socket is the green socket with an arm to close, making it easy to insert and remove the eproms)
My willem programmer is similar to this one : http://cgi.ebay.com/Willem-Universal...efaultDomain_2
the 16bit adapter can be something like this

and regarding to me killing my roms, I suspect the parallel port of the computer I used
