Further stuff by me

Here is some stuff. By, for the most part, me. :-)

For the web

• enc100em, emulates an Amstrad NC100/NC200 running ZCN in your browser.

For various systems

• lbrate, extracts/decompresses CP/M LBR archives.
• nomarch, extracts old .arc archives.
• zmakebas, converts text files into Spectrum Basic programs.
• zpsoli, a portable Solitaire/Patience/Klondike card game in awk.

For Unix/Linux

• k3, displays free memory as a bar chart.
• nc100em, an Amstrad NC100/NC150/NC200 emulator.

For Z80/8080-based machines

Amstrad NC100/NC150/NC200

• ZCN, a CP/M-like operating system for the Amstrad NC100/NC150 (Notepad) and NC200 (Notebook).

Generic CP/M

• zcsoli, a Solitaire/Patience/Klondike card game for CP/M.

Sinclair Spectrum

• p3c80, a device driver for +3 CP/M with 85x24 terminal output, as well as 80x24 and 64x24 options.

Sinclair ZX81

• Shapestack, a puzzle game for the 1K ZX81.

Miscellaneous stuff

• Linux trivia - 2 bits on 1 bit in 0.x.
• Prompting for short answers from a large language model.
• Stuff and nonsense, said Alice loudly.
• Tips on buying an NC100 memory card (or not).

• A note on my public domain programs.

Stuff only slightly by me

I've made contributions to these programs written by others:

• A few things in the Fuse Spectrum emulator, like the original sound emulation (including what was perhaps the first open-source emulation of the 128's AY-3-8912 sound chip) and some of the printer code.
• The original version of netpbm's pamstretch (as it became) and a few of the converters.
• Additions to the older Spectrum emulators xz80 and xzx, including the original xzx level-loader trap as later used in SLT files.
• Some speed optimisations for CP/M unzip. The multiple versions make this a little confusing, the versions I contributed to were 1.5-3 and 1.5-4. My changes were also adapted for 1.84.
• Various changes to the old Z80 cross-assembler zmac.

My code has been making Linux distributions buggier since 1995.

For other stuff, see my older page like this one. I don't do as much programming as I used to, so to me it seemed simplest to just have a new page mainly listing any newer/updated bits and pieces.
