Thank you very much for the picture ,i tried to put by order but no result,aparrently the only way that boots with corrupt screen is with order changed.
I tryed also to change to 1mb config and burn 2 chips on lo-o and hi-0 with 2 chips 27c512 ,swapped rom and no swapped both with no sucsess.
I split in 2 a tos 1.04 with tottal commander.
Ciuld be a problem with splited rom
So if anyone could post a valid 2 rom image with tos 1.04 i would appreciated.
The test cartridges on the site posted here are very expensive ,i saw 1 by 56 Dollars
that pplus travel expenses make me do a bad bisness on this atari
i suspect ram issues but not sure,as far as i know this machine has beem on outside and could be a tottal loss
,it´s strange because it boots,could also be mmu and glue chips,what are impossible to get now a days over ebay at a good price
Best of regards to all that are posting here and other users.
