6502 emulation on LCR-T4 component tester?
« on: August 03, 2020, 11:56:55 pm »
Hi there.

How feasible is it to imagine that AVR emuation of a 6502 could be realised on the "LCR-T4" type component tester? These have excellent dot matrix LCDs - I am currently playing (very much flying blind, based on my current sub-primitive understanding of 6502!) with a 6502 emulation on an Arduino Mega 2560: https://github.com/mkeller0815/MOUSE2Go , but I feel this could(?) be ported or whatever, to the LCR-T4 (once I backup the tester firmware, trivial) as it has crude input (button) and display for O/P.

Please note - I have no "goal" for this pursuit beyond that of playing and learning through said playing.

Thank you for your help, I humbly bow to your knowledge.

It is very easy to imagine.  :P

On a more serious note: What would you want to do with it?

The I/O seems rather awkward -- a nice, but rather small screen, which neither matches the very limited display of the earliest 6502 computers (KIM-1, AIM-65), nor the larger CRT of the later ones (Apple 1 and 2, Commodore PET...). And no keyboard at all. You could connect a serial terminal, but then you don't need the on-board screen.

If you want to dive into 6502 assembly language programming and the "early days, low level" experience, I would recommend that you start with a real 65(C)02 single-board computer. Many hobby projects are documented online; to name just one example, the author of the AVR emulator which you linked to has started with his own "real" 65C02 computer first: https://github.com/mkeller0815/MOUSE

Or, of course, you could look for an old Apple II or PET!
