There is a 'Computer Store' in town that is, like most, useless in that the sell only. Support? "Nope, never heard of the reference manual. Here call Addison-Wesley, long dist., and get told that the dealers have it, not them." Does anyone have one?? I *need* it for my apple (Hacking w/ no memory locations and timing chart references is a bit impossible. Thanks. Also, A recommendations for a good ProDOS reference/users manual. I'm faking it now and need help. Has anyone tried making their keyboard separate from the case. I'd _LOVE_ to take a 3rd party keyboard (maybe w/ function keys and a keypad!) and replace the ][+ keyboard. It's nice to sit back and type. Summary: ProDos book, ][+ reference manual, and External keyboard info. Thanks. 65802 comments . A friend (MKRIEG) did it to his ][+ successfully. It is a 6502 (w/ extended instruction set). same speed. same pinouts. same everything. Then you set a status bit. It becomes an 8 bit version of the 65816. (like the 8088 is 8 bit, 2 consecutive reads for a 16 bit number.) Why do this? Because people are writing (and you can too) for the switch. Moreover, for you hacker (gasp) types, you can do 16 bit multiplication in assembly in one swell foop. 65,535 in very small cyclage. 32 bits in the time it once took 16. VERY fast graphics calculations. For word processing, and such, most of the time is spent waiting for user input. A friend programs mostly in basic, and puts time-essential routined in assembly, runs fine. Good investment for some people, not for others. But doesn't that apply to _everything_? And an extra note to stir up some controversy: Since 6502s are SO cheap, I wish they made the GS a 68020 (/030) w/ math coprocessor machine, using a lookup table to convert op codes and a 6502 for the Disc I/O for because of the Apple's timing strangeness. The 6502 _is_ a nice control system chip, but as a computer?... +-----------------------------------------------+ REALITY (& Summer) Chuck Yerkes, Box 1023 Amherst, Mass. 01004 - - - - - - - - - BITNET: CYerkes@UMass.Bitnet ARPA CYerkes@umass.bitnet@wiscvm.wisc.EDU +-----------------------------------------------+
