Assembly on a Apple IIc+

Ron, This is just my preference. Pick up Apple Pascal OS (UCSD P-System). It comes with a more than adequate assembler and editor plus the Pascal interpretive environment made it very easy to test assembler subroutines. I recall putting together 6502 assembler for higher precision paddles, interrupt handling (IRQ) for Hayes micromodem & Corvus network, direct screen buffer access for animation, compression, conversion (ebcdic-bcl-ascii) etc. The Apple Pascal OS needed 64K (16K language card?) but was very sparing on program memory requirements. Pascal was compiled into very compact P-code (shades of today's Java byte-code). Apple Pascal also had builtin memory management allowing you to put together very large applications. I ported wall street applications from IBM mainframe and Burroughs mainframe to the Apple ][ and was able to add features. I loved the Apple ][. I was always able to do whatever I wanted on that baby. Have fun! - Jim p.s. I also did quite well with 6502 asm code in cpu speed tests vs 80x86 and Z80 programmers. The zero page, for all intents and purposes, is 256 registers. 6502 is single cycle instruction execution. Look up definitions of RISC and the 6502 is arguably RISC-like.
