#Apple // Character Generator for HGR#
|
||||
|
||||
- Author: Urs Hochstrasser
|
||||
- Date: 1987
|
||||
- Platform: Apple //
|
||||
- Language: 6502 Assembly
|
||||
- IDE used: Merlin Assembler (8-Bit)
|
||||
|
||||
My assembly line dabblings created back in 1987. In fact this is already version 4 of a project I probably started back in the early 80ies.
|
||||
|
||||
I provide the code as is. I haven’t touched it for decades. Have fun!
