#A1200 compatibility?

I read that lots of old games don't run on the newer machines like the 1200… But then I read that you can boot the new machines such that the new graphics capabilities are essentially disabled, so that they emulate the older graphic chipset. If the 1200 can emulate the older chipset, why would older programs still have problems running? Should I really expect to lose the use of many of my old games for the A500 if I upgrade to the 1200? And is the A600 more or less compatible with old games, compared to the A1200? Thanks, ===Scott

Scott, Essentially, all of the programs that I couldn't get to work on the A1200 in ECS mode with the caches off also wouldn't work on an A2000 running AmigaDOS 2.0. In other words, 99% of the stuff that's going to break is stuff that won't work on a machine with >AmigaDOS 1.3 either. The A600 is marginally more compatible–games that don't work on >68000 processors will work on the A600 but not the A1200.

>In other words, 99% of the stuff that's going to break is stuff that won't work on a machine with >AmigaDOS 1.3 either.< Are you saying that you can't boot the A1200 from a floppy with a version of AmigaDOS earlier than 2.0? ===Scott

You can boot with Workbench 1.3 (or 1.2), but the Kickstart ROM in your machine is still going to be 3.0. I'm saying that stuff that was incompatible with Kickstart 2.0 is going to be the stuff that's going to be incompatible with 3.0 as well. But the stuff can be on a 1.3 Workbench disk.
