Hi I'm a completely useless programmer and therefore not really qualified to pass comment but I thought it might be of interest to some members of the forum. I came across a tiny basic computer on GitHub .It uses a single CH32V003 running basic, generating monochrome V.G.A and reads a PS2 keyboard, with storage via up to two eeproms. It was suggested by the designer that it would be suitable for a beginner, there is a workbook with exercises and possible solutions I rather liked. I have not tried it out yet but as soon as I get the bits I will have a go, I do not expect great performance but I think it will be a bit of fun.

Hi Spock,

I think you can have a lot of fun with this mini computer. Tinybasic is very simple (although it uses line numbers). I am not sure if this had an editor, possibly you have to retype lines when you want to change anything.

Tiny basic however can not be compared to MMBasic, that is favorite on this forum. MMBasic is more powerfull. But honestly, I have done quite a lot of simple programs in Tinybasic. So have fun... enjoy, and when you are up to a step-up, try MMBasic on RP pico (PicoMite). The simplest MMBasic computer can also work with the same VGA monitor and PS2 keyboard. So it is "plug and play" for you.

I agree completely Volhout.I have been on the steep side of the learning curve with MM basic since the monochrome maximite, the Picomite is amazing, but for some of my blinky flashy things it's overkill. I like to screw the last bit out of every device I use ( I used to play with regen receivers a lot). Its a pity the designer did not produce a version without the PS2 and VGA it would be cheap enough for embedded projects and cheap enough to be expendable. I know this is mainly a forum for MM Basic, I find a lot of other forums are very partisan I'm not even sure if risk V even has a user group yet.
P.s I would still be using NE555's but I can't be bothered with the extra bits anymore
(grin)

What do you use that is less overkill than, say, the RP2040-zero for $2.19USD?

Several people have produced PCBs for this module.

PicoMite, Armmite F4, SensorKits, MMBasic Hardware, Games, etc. on fruitoftheshed
