This is my 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 as well as the Tynemouth joystick module on port $01.

The game play is quite simple:

In true retro-computing spirit, TMSnake was written in DX-Forth for CP/M-80 on a real RC2014 homebrew computer. This also includes the required TMS video driver, the custom character set and the AY driver as well as the actual game code. It took me about a one and a half year to finish the code and it has been an interesting lesson in simple game mechanics for me.

lots of fun here ...

This is a simple implementation of the "Snake" game written in DX-Forth on a RC2014 and utilizing the 8x8 LED matrix module.

After having taken a break from soldering over the past few weeks, I enjoed a little training exercise today by building a FIGnition FUZE that I had lying in the shelf for he past eleven years. It is a simple DIY computer kit based on an ATmega chip.

Turns out I missed quite some fun here as the flash rom contains a good load of demo applications and games, including "FIGtris" a Tetris clone

So this is the second machine I built that comes with Forth built in (the other one being the MyNOR My4TH) and I am quite surprised to see how well the 8-button keyboard of the FIGnition Fuze actually works in practice.

The My4TH Forth Deck goes Telnet:

I've used a SC16IS750 UART and connected it to my Forth Deck via the I2C bus. This way, I've added a serial interface. The UART, in turn, is connected to an ESP8266 running the Zimodem WiFi modem firmware.

The "terminal" program is a simple demo of mine snippet without any terminal features:

My4TH discrete cpu computer uses a few I2C devices and some custom FORTH code written by myself to do some show off.

I coded the BMP180 sensor driver calculation routine for the tempereature myself, as well as the neat thermometer demo code. The I2C LCD driver is provided on the My4TH website.

This is the result of myself trying to get into FORTH on a CP/M machine.

So here we have some FORTH, some inline 8080 assembler in order to talk to the output ports for the LED. I learned a lot during this little exercise and am pleased with my prgress so far.
