Anyone here tried the Nano Vic-20?

I was looking at Jan Ostmans reprogramming of the Vic-20 to squeeze it into a Arduino Nano: https://www.hackster.io/janost/the-nano-vic-20

Since I have a Mega 2560 board with 8K SRAM lying there, I was thinking it might be possible to get a version with a bitmap into that.. Anyone tried it?

Please post any pictures if you are getting this working, will love to se it.

Wow! WOW! Watch me go pale. If that shift register could be operated with a higher resolution I bet this thing could do color. What a pity that thing is so expensive.

That's cool! I wonder if it would work on the MicroView (tiny Arduino with built-in screen)

Uh!? Where did you look? I only get a price range from €30–40. :shock:
EDIT: I mean the whole board, breadboard–compatible with USB connectors.

Ah, O.K. I only saw offers with the pins soldered on. Now we're talking! ;)

Is the emulator code only 178 lines? :shock:

Nope. The CPU emulator is another 1384. Grab that cpu.c file. The bit you got is just doing video and memory access. Unfortunately, the VIC emulation is totally static. Writing to registers won't do anything.

Ok, thanks. It is only for "show off" then, not an actual emulator?

It is actually a super–*******–amazing emulator, only restricted by the lack of RAM. I didn't get mine to boot BASIC… This is artwork.

Has anyone added keyboard support for this yet? I bet it would be fun to play with if it could stand alone. Heck add sd card support and now were talking.

It does. I even stole a bit of BCD arithmetic code for shadowVIC from it. 8) Which I assume the original developer noticed rather quickly. :)
