Flight Sim History

While googling up another arcane feature of the Atari ST system hardware I stumbled over this: The Flight Simulator History page. It offers a very comprehensive history of all versions of FS and background about its creators, and then in addition pre-built emulator packages so you can go and check out what Flight Simulator looked [...]

1000 Instructions and Counting…

Coming back from a programming break over the holidays, I went back to work on my ST emulation… The CPU is making steady progress and for the first time the emulator ran through 1000 instructions without a hiccup. It finally coughed up an exception on a bit shift operation about 1300 instructions into the TOS [...]

Impulse Purchase!

If you’ve used an original Atari Joystick back in the 80s, you know that there was something very special about that joystick. I could never figure out what it was, and undoubtedly the ergonomics of every other later joypad/analog stick thingy was far superior. But still… there was something to that old square box, all [...]

Of Writing a CPU

I’ve always been fascinated by software emulators. The earliest example I’ve used that I can think of was a ZX Spectrum emulator on an Atari ST around 1987. I had a real Spectrum for some time at that point and had just bought a ST the year before, when I found this program on a [...]

The Clones Never Sleep

While I was doing some research around the behavior of Atari ST hardware, I found several interesting sites with quite amazing hardware projects around the ST. There are several people who are in the process of building complete Atari clones based on VHDL (programmable logic chips)! Here’s a few very promising projects: S Like Suska [...]

The Making Of…

It’s interesting to see developers open their programming process to the world on their blogs. Here are two recent examples that I found while looking for resources on emulator programming (ahem!) – Miggy is a blog from Bristol in the UK and the owner, t0ne, started work on a Amiga emulator in Java in October.
