Return of the 8bit Bell Bottoms

Sat, 27 Dec 2025 15:30:03 +0100

While I am generally not interested in purchasing emulated (retro) hardware, I made an exception for the Altair 8800 mini.

As the name suggests, this is a replica of the legendary MITS Altair 8800 microcomputer from 1975. I will not get into the history of this machine as there are plenty of other sources elsewhere on the net covering that in full detail.

ESP32forth: transfering files to and from the SPIFFS partition

Thu, 07 Aug 2025 15:49:26 +0200

One of the things that annoyed me when using ESP32forth is that with recent versions of the ArduinoIDE (2.x) it is no longer possible to use plugins for uploading additional files to the SPIFFS partition of the ESP32.

There is a workaround solution for ESP32forth that allows a user to copy-paste code into the terminal, which is then stored on the filesystem - but that didn’t convince me.

TMSnake

This little game is an adaption of the well-known “Snake” game for CP/M compatible RC2014 homebrew systems. It runs on both, SCM and RomWBW based CP/M variants.

It requires a TMS video module on MSX I/O ports $98/$99 and optionally supports an AY8910/YM2149 sound module on ports $D0/$D8 or $60/$68 as well as the Tynemouth joystick module on port $01.
