Recommended Posts

There are some eBay sellers who also offer programming service for the EPROMs they sell, usually for a reasonable fee.


The following eBay links are for EPROM chips whose sellers also offer programming service. A 27256(32kB) can contain 2 different OS's, and a 27512(64kB) can contain 4 different OS's, on the same chip.


A 27256/27512 can also contain multiple copies of the same OS if only 1 is desired.


27256, $2.48 + shipping from Ireland, seller offers programming service/fee not stated

When you are up to your waist in alligators, it is hard to remember you came here to drain the swamp.


I promise I will get back to you regardless of outcome. :) I'm a little bit busy but give me a day or two to see if I have all the parts for a DOS computer to house my PB10. I think I may have a 27128 or 27256 laying around to use so IFF I won't have to wait for eBay.

Can anyone burn OmnimonXL and OmniviewXL or OSNXL for me I was after OSNXL but B&C seem to be out of them. :spidey: Oh I'm in NTSC land if that helps out any!


You may send me a blank 27128 or 27c128, and PM me the binary file you want on it.


The cost is for shipping only for AtariAge members.


Please PM for more info.
