Updated to fix screenshots.
been lurking for a little while and now hoping some wiser heads can help me. In the 80s and 90s I was a BBC then an Amstrad user, I missed out on the 16bit Micros and became a PC user.
I'm currently the (almost) proud owner of my first Atari. It's an STFM1040 purchased from ebay.
It boots to the green desktop and seems to attempt to load floppies. I've actually replaced the Floppy drive now with a modded gotek and oled display.
Loading software always causes a crash (various bombs).
I've tried using some diag software which has indicated a RAM fault. As I'm hoping to get a little more into the care and repair of this Atari I recently also purchased the diagnostic ROM cartridge. This seems to confirm there is a RAM issue. See the picture below, or at https://ibb.co/8bjSkdp
It's suggesting that bit 14 is causing the error?
The layout of RAM chips on my 1030 is 4 banks of 8 chips.
This is not my board although the RAM layout is the same
I'm hoping for some help in relating the address to a particular chip please?
Which of the 32 RAM chips would hold bit 14 in the memory range listed in the diag screen?
