My 800XL ROM is sick. The memory test on the ATARI shows the left hand
bar in red (meaning that the ROM is bad). Does anyone know of a quick
(and cheap) way of replacing the ROM. Can I burn a new one ? Can an ATARI
ROM be purchased at a reasonable price ? I have the ability to replace the
ROM myself - I just need a new one.
Your help would be appreciated.
Thanks
ps: I purchased the 800XL a few years back (when it was still quite
expensive) so I'd rather not just buy a new 800XL.

Try looking in either Antic or ANALOG for an ad from American TV. They have the ROMS. I don't know the prices. -- Marc L. Appelbaum "Insanity is just a state of mind" Arpa: marc@aim.rutgers.edu Uucp:rutgers!ru-blue!appelbaum

If you have access to a good ROM, an EPROM programmer, and 27128 EPROMs, you could duplicate a good one. As far as I know, the 600XL, 800XL, 65XE and 130XE all have the same ROM. If you have a friend with a broken machine of any of these types, you could also try to use a ROM from it. I have used a 27128 EPROM (either 200 or 250 ns, I don't remember), and know that it works. If this is not feasible, there are several places which sell Atari parts. American TV and B&C Computervision come to mind. They advertise in Antic and Analog, among others. I have not dealt with either, but I hear that they promise delivery in the 4-6 week time frame. Price should be around $10. Finally Computer Mail Order (again, I have not dealt with them) recently advertised 600XLs for $30 or $35. Since they are identical to 800XLs except for the memory circuitry and the video output, you would get a great supply of spare parts that way. Of course I don't know if they have any left. Before doing any of this I would try to swap parts with a good machine, to be sure it really is the ROM and not some other part of the memory circuitry which is causing the problem.
