Hi it nice to see people take an interest in this design. I'm not having time and energy to work on a new version now. Also because the design moved...

I guess this is related to GCC 10. I'm on GCC 9 and don't get that error, however if I set -fno-common option I get the same error. You can...

https://github.com/mist64/cbmbasic/blob/89093eba090d6e1c2d2b6e1cb1616dba0ce9c7f6/runtime.c#L47 this should be extern i think. Yep, just tried this now and it works.

If I'm not mistaken, "tinyAVR® 1-series" are not implemented. I wonder how different this core is compared to AVR and how much work it would be to implement them into...

I second this. Great idea to update the apt repo. I'm on ubuntu 20, and the avra version I have is from 2010. The -o output file name option has...

No problem. Regarding the traces that seemed to be touching, when i zoomed in on the artwork from eagle (in the paint.net file), it looked like there was a trace...

Has anyone looked at this problem? In short, the challenge is that the "output" of U1 does not go to 0 V, it goes to around 2V and varies with...

I've been simulating a tl431 with cathode voltages from 1V to 2V. With a bipolar npn transistor replacing Q1, the threshold is a lot more stable than the nmos transistors...

Hi again. This problem is with the threshold of 2n222 and variation in tl431. Regarding the led problem we can have a look at that in another issue :)

maybe i misunderstood. im playing with lt spice now. I'd like to take out the leds until i figure out the problem with tl431 and 2n2222.
