Well, Hello There

This site has existed continuously since 1994 and has gone through more redesigns and reincarnations than something that's undergone slightly fewer redesigns and reincarnations. All code is vehemently unsupported, all information chronically obsolete, all opinions doggedly idiotic and all artistic merit highly dubious. Stick around, we have more adverbs and we're not afraid to use them.

The CFT Project

The CFT is my home-designed, home-built mini-computer made from scratch. I've designed and built the instruction set, data path, processor, computer, software stack, cross-assembler, emulator, software toolchain and even some of the tools needed to do this. You can call this a ‘fantasy mini’. I'm in the process of testing the processor and building peripherals and the ROM, while trying to document the whole thing.

DFP 2 Render, revision 1939

I messed up—the previous revision of the DFP had the backplane connectors mirrored, so it'd never have mated. I chose to redo the board from scratch, but the layout is better and it looks nicer now.

I've known about the Raspberry Pi since it first came out, but I'm now the slightly underwhelmed owner of my first, very own Pi. To be fair, though, I bought it to drive my brand new PiDP-11.

The Easter Notes

Using KiCad, sweeping and much needed changes to the CFT are finally possible. These notes discuss most of them.

Dæmons Behaving Badly

Sometimes you encounter weird problems, and drilling down reveals something weird and interesting which of course makes sense in retrospect. This is an account of one of them. It's a simple problem with an easy diagnosis and an easier fix, but all three demonstrate how important it can be to understand at least the basics of Unix, not just stringing commands together until something works.

I'm toying with the idea of making The Machine Room available again, as an essentially static site. First step: getting a Python parser and renderer for the XML format used for the entries.
