MaxiMite project #3

I managed to flash the MMBasic firmware to the UBW32, then connected RGBHV using VGA through the required pins, using fast-switching 1N4148 diodes to ground on each of the R, G and B colours. Apart from a little ghosting, which I hope will be better when interference is reduced, the image quality is fine. There is no PS/2 connector yet, so all I can do is watch the image. Yes, that IS a Ducky Shine Year of the Horse Edition keyboard!

MaxiMite project #2

Ready to install new firmware on the UBW32. This is not something that is well-documented, compared to something like Arduino etc. – but few things are. The USB drivers are not even verified as working on Windows 10. So, it seems old and random to me. But anyways, let us try.

MaxiMite project #1

Recently I have been very interested in the MaxiMite project, after watching 8-bit Guys video on the topic ( https://www.youtube.com/watch?v=XQA8lowEKOo&t=229s ). It is an older project, created to ‘imitate’ an older 8-bit computer – like the C64. It is running MMBasic, which, in this case, has the ability to control I/O ports of the PIC microcontroller it is running on. It seems to me (not an expert) that MMBasic and MaxiMite beat micropython to the punch, but did not make a big splash?

Well, I have just received the UBW32 PIC microcontroller board, which also has the ability to run color MaxiMite. Then I will need to hook up a VGA port, a PS/2 port and an SD card read+write. These are in the mail.
