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.

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.

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.
Once you start coding in Forth for a while, you may come across a situation where you want to write a sequence of bytes to some memory location (e.g. if you want to store the sprite data for a game). Out of the box, Forth provides the word C, to store arrays of data which can then be written to the desired memory address using a DO…LOOP and MOVE in your code. However, I wanted to reduce overhead in my code and so I defined a custom word which is similar in function to the READ … DATA command you may know from the BASIC programming language. Here’s how it works.
Read more...is (probably) the first RC2014 based bulletin board system in the world! It is a classic 1985 bulletin board based on the RBBS 4.1 (BDS C code) software and utilizing a RC2014 computer kit running the CP/M 2.2 operating system and the BYE5 communication program to interface with the outside world.
It features several boards (called “subject files”) users can communicate through, allows undisclosed personal messages and lets you access the CP/M command line.

This also means that all the previous content is gone for now and will only be partially restored. New ideas and new projects will instead be made available to the public.
The past four years have been quite an interesting ride as I’ve become a big fan of the RC2014 “homebrew” 8-bit computer platform.
