Commander X16

GETIN ($FFE4) returns zero if there are no characters in the keyboard buffer, I think.

There is also https://style64.org/petscii/ which is good for exploring the relationships between different character encodings

Could you try changing the !text directive to !scr ?

How are you getting the text into ram? I suspect it's an encoding problem.

Also, typing ‘m A134’ in the debugger will show the memory values in the lower section.

Could you post what it is supposed to say?

The 6502 is little endian. This means that when using a 16 bit number (like an address) it expects the 'low' byte to come before the 'high' byte in memory. So you need to swap some bytes round. For your example, you should have startLo = $14, startHi = $15, then lda (startLo),x.

Hope that helps.

Thanks for the info.
