nice effort. even with a limited hardware and initial design choices set in stone the software is always the key factor in the usefulness of the machine.

these limits were a fun chanllenge and made me focus on what matters, I just wrote a bit of example code to test functions like TONE and DWRITE ye, but most old BASIC game listings should work.

14:14 Interestingly, to me anwyay, the reason the ZX-80 and 81 do the "BASIC shortcuts" is because you are tokenizing the command as you type. Other 8-bit computers processed the text string "PRINT" and converted it to a token. However, to save space in their tiny ROMs, Sinclair made the user do the tokenization.

Where is "tokens" really from? We called it a byte for many years.
@bald_engineer4 ай бұрын
@@elektron2kim666 It’s been around since the first BASICs. A token is different from a byte. It isn’t a data type. It’s a concept.

A possible add-on that comes to mind is some sort of paper tape reader. The reader wouldn't have to be too big (especially if it's hand-operated and doesn't need motors) also, the tape can be very compact once rolled so it would be easy to carry prewritten programs, load them, and run them! I'm gonna have to dig out my Arduino and try something similar soon!

Too late, but: you could run the display in 4 bit mode to free up 4 pins.

When you look closely on the schematic you wil lsee tha tI am only using 4 bit mode. Db4-7 are the only data lines connected to the MCU, I did use up all the pins for this project even with 4 bit mode.

Why not use a line with a series of resistors and a ADC for reading the keys?
@MAYERMAKES Жыл бұрын
that is another method, but unreliable with so many keys, the voltage drop across each resistor gets to big quickly, the differences very little, and there is no n-key rollover possible that way, gohst presses also might occur. I would not rely on analog readings for key inputs in any case but if there really was only one pinn available up to six keys might work, but still no combinations possible.
