DriveWire server and memory test utility

Post by sorchard »

I've finally got round to publishing a couple of Dragon projects I've had kicking around for a while and thought they might be useful to others.

Firstly we have yet another Python DriveWire server. I wrote this because I needed something relatively simple that supports the DriveWire hardware and software developed by Tormod Volden. There are much more sophisticated DriveWire servers available, but this gets the job done with a minimal footprint.

The other project is a memory test utility for 32K and 64K machines. This performs walking bit and pseudo-random pattern tests in a continuous loop until a failure is detected.

It's been written in the most masochistic way possible, i.e. using position independent code, without a stack and no memory variables. This allows the code to be resident in a cartridge ROM and run in a meaningful way even with bad memory.

If run from RAM, the code moves itself and the video screen around to allow the memory to be fully tested.

Adding my vote of thanks too! Just upgraded a Dragon 32 to 64K, and the memory tester has been invaluable. Cheers Stew!
