So the following would be a scale of compatiblity for ProDOS 8 programs: Level Instruction Set Memory Suitable Hosts ---------------------------------------------------------------------- 1 6502 64K ][+,][e,//e,//c,//c+,//gs 2 6502 128K ][e,//e,//c,//c+,//gs 3 65c02 64K/128K //e,//c,//c+,//gs 4 65c02 256K+ //e,//c with aux ram card 5 65816 64K/128K (//e,//c)*,//gs 6 65816 1M+ //gs ** * assumes user has replaced 65c02 with 65802 Could a //c+ have this done to it? ** Level 6 is probably outside P8 and into GS/OS territory This table also ignores Zip Chips in ][+ for 65c02 code. Sample programs: ProDOS 8 v1.x is at level 1 ProDOS 8 v2.x is at level 3 Merlin 8 is at level 3 (128k) Merlin 16 is at level 5 (128k) Any comments? -- David Wilson +61 42 213802 voice, +61 42 213262 fax Dept Comp Sci, Uni of Wollongong david@cs.uow.edu.au
