The BSX Homebrew Project is an interest challenge for me, as it involves hardware and software. I’ve been concentrating on the hardware up until now, but there is a reasonable amount of software running on ROM now to assist in further hardware and software developments. If you want to cut to the quick and go straight to the source, you can find it here on my GitHub. The Monitor Program The BSX boots into the …
One of the advantages of lockdown is that spare time is often in plentiful supply. I noted a few months ago that BBC Basic for Z80 by R.T.Russell is now open source, and available under a zlib license. Inspired by the work of David Given who has included it to his CPMish project, I decided to have a crack at porting it to my BSX Breadboard Computer. I had to fettle the source files slightly …
I left the project in the previous post with a ROM on-board, but still running NOPs – it was running an EEPROM filled with zeros. The next step is to find a way to run programs and see the output. In order to do that I will need to do a few things: Add an STM32 ‘Blue Pill’ microcontroller to handle I/O Add an LCD display module to output debug information from the STM32 Add …
