This is just a pointless proof-of-concept for fun, but I found a way to boot the Linux kernel directly from a running CP/M-68K instance.

I read an article that someone had managed to get Linux running on a Sega MegaDrive which has a Motorola 68000 CPU and no MMU.

Here is a set of programs to easily display an image on the LCD screen of the Epson HX-20.

Just for fun I modified a Famicom cartridge to use custom EPROMs, in order to run a ROM hack the old fashioned way.

During a recent trip I worked on a Gameboy emulator using my 14 year old Asus Zenbok UX31A, using a limited set of tools and my experience from earlier emulator developments.

Sometimes I need to transfer text from my Android smart phone to my Linux PC.

I saw this video by Necroware earlier, about the possibility to extract the contents of the RTC modules found in older PCs.

Around 18 years ago I made a program to control a "Cooltek" LCD display over the parallel port from a PC.

I bought a Lode Runner cartridge for the Sega SG-1000 while on a trip to Japan.

I have a Sega SG-1000 II that I have modified to work with composite video and audio.

Once again a dead RTC battery, but this time in a 16 year old Acer Veriton N260G NetTop PC.

Although I added support for the piezo speaker some time ago in an earlier version, it did not sound very nice, especially if trying to play back any music.

There exists a somewhat famous video which has a "monochrome" animation and music made by Alstroemeria Records based on the Touhou Project.

I have added Unicode text support to my tmce64 emulator and bumped the version number to "0.5".

I got a .no domain now, so the web hosting has been moved yet again after being around 6 years at the other place.

I have made a minor update to my a2c emulator.

I started a new emulator experiment, this time a PDP-11.

I had trouble with a PCI express parallel port card in a modern Linux box not behaving as it should, so I decided to make a test setup.

This is kind of like a follow up on the CHIP-8 Interpreter for Epson HX-20 that I posted about earlier.

In order to simplify the creation of audio files that can be played to a Epson HX-20 I have reverse engineered the format used for binary files and created a C program.

CHIP-8 has been ported to several platforms, but I decided to port it to the Epson HX-20 since the hardware is capable enough.

This is a new version of the Python Image Viewer posted earlier.

There is a serial terminal emulator program for the Apple II called ASCII Express which can run in 80 columns text mode.

Earlier this year I started coding on a Motorola 68000 emulator.
