Altirra 2.20 test 7 [October 03, 2012]:.

- Debugger: Extended many commands to accept expressions for address and length arguments.
- Debugger: The default numeric base for addresses can now be changed (.base).
Author's Comment:
- Nothing big here, some tweaks to the debugger and a placeholder U1MB BIOS. It provides just enough OS functionality to run a U1MB flasher disk. You still need to configure the hardware settings juuust right to get U1MB to work, which I need to fix.
- Not sure about the TBXL flash, but one thing that comes to mind is that U1MB is static RAM, and therefore will have different uninitialized data in extended RAM compared to a stock 130XE.

I had access to a number of 8-bit computers in my childhood, but my most favorite was the Atari 800, a 1.79MHz 6502-based computer with color graphics and a disk drive, and which as the predecessor to the Amiga, another favorite of mine. Over a decade later, I was struck by both nostalgia and ambition and started to write a new 8-bit Atari emulator from scratch. This is the result.
At this point, I've learned a lot more about the Atari and Altirra now emulates more than I ever had or did years ago, but I still work on it periodically. It also serves as a modularity test for the VirtualDub code base, from which Altirra shares some components. If you are struck by nostalgia too or have a desire to do some Atari development, perhaps it might be useful to you, too.
