Just the old school method of OS disassembly and/or boot disk sector disassembly too. Some are very cryptic in the way they go about it while others read like good novel.
This and file structure, the ways and means of DOS, etc. need to be in book. But no such book exists that I'm aware of. Best we've got is cut up coverage in Mapping the Atari with a very light touch given to the meat of the subject usually. Just enough to fuel an insane quest to disassemble the entire OS for example. Three months down that road and "Oh, there it is".
XBIOS not something I'm aware of or interested in, sorry.
EDIT: In Basic, lowering the luminance of the text seems to help with the ghosting issue. Is there any way I can fix this at a hardware level?
Sure, you can construct a resistor network to cut back on the level of luminance and/or chroma both. Some insist on a 75 ohm resistor in line to 'match' impedance to the TV/monitor but this is misapplied #Fake News nonsense for RCA type connections in the first place. Make it to be what works but understand that it's probably only going to work with that computer and that monitor both. Change one or the other and the problem may show back up and in reverse this time. 75 ohm inline wouldn't be a bad place to start either. Which doesn't help any with the repeated rumor that it's the only proper fix.
It's well known that the output levels of these computers is quite variable, one is way to hot on luminance and the next has chroma just a screaming.
NO INGUTS!!! Got it. Kind of weak sauce but if it's enough then yeah, I'd be wishing I had bought more at $20 too.
Wasn't there a guy from Poland or somewhere that made a little module to replace the C060472 delay chip? I saw this a long time ago, and it disappeared.
Me too, but from what I could tell it was impossible to be an actual replacement. Thread kinda died at that point so I'm thinking well it didn't work and those that didn't want to rake him over the coals publicly just let it die like that. A non- working scam gone full tilt eBay, how unusual.
I was born at night, but it wasn't last night. 3 AM, what a PITA huh?
