Shure about that ? The Apple ][ had a dissassembler and mini assembler in it's ROMs, while starting with the ][+, or to be more correct, with introduction of the Autostart ROM/Applesoft ROM the mini assembler had been removed (together with the Sweet16 interpreter, some Monitor commands and some other usefull subroutines. I still remember that one of my first long session on my brand new A][+ in 1979 was to key in the mini assembler from the ROM listings and modify it to run in memory (address changes) ... It took me almost two days without sleep - and soon threafter I got a small loan to buy two disk drives - working from cassette did work fine on a KIM with quite small programms, but on the Apple with huge, one, two or sometimes 3 KILOBYTE programmes was a different task :)) Gruss H. -- VCF Europa 3.0 am 27./28.
