Thinking about returning to coding Dandelion BASIC, the Tiny BASIC implementation I was making for the ATmega 2560, in assembly language.
In order to keep things structured, I turned to the 8080 implementation of Tiny BASIC Extended from the Dr Dobbs Journal.
Turns out the author has a current website, and I was able to glean how he was able to port quite a bit of the 8080 paradigm over to AVR assembly.
My job was to try and code overlapping processor paradigms, so I put it down for a bit.
The job is simple enough, but what I had intended to be AVR assembly is now AVR assembly imitating 8080 assembly, so square that circle.
The major difference is using the register pairs X, Y, and Z in place of, or contiguous with the 8080 HL register pair conventions for 16 bit memory addressing.
You can see how this has become a mammoth task.
Nevermind the routine INSERT which manages the list of BASIC program code in memory, now that I remember that code I remember why I gave up months ago.
