From: Ken Adelman <KEN@JPL-VLSI.ARPA> My roommate just purchased a //c (I have a II+) and I have some random questions not found in documentation I have been able to find: 1) Does anyone know the pinout on the joystick/paddle port? I want to interface a normal apple II type joystick. 2) Does anyone know if/how to interface an apple disk ][ to the apple //c? I know that the connector is different, but is it possable to make a cable to connect the two. I have an spare disk ][ I am not using. 3) Does anyone know the memory address used to toggle the $400-$7ff bank of ram back and forth so I can write the screen directly? 4) Does anyone know the pinout on the serial ports? I don't want to spend what apple wants for a $1 connector. What about the interface itself? I would assume that apple used the 6551 ACIA. Does anyone know where they are mapped (both modem and printer)? How does apple expect the printer to handshake (^S/^Q or 5 wire serial)? I am trying to modify a VT52/H19 emulator to work on the //c. Answers to 3 & 4 may be rewarded with a beta-test copy. -Ken Adelman Caltech (KEN@JPL-VLSI.APA) ------

Software and Hardware advice needed for Apple //c A close friend just received an Apple //c as a present and now has come to me for advice. After having boasted about the virtues of C, he is not content with Basic and desires a C compiler. In addition, he will probably need a printer (although I believe he had an Epson from his old Commodore-64 days). Wanted Advice on the following: C Compiler Should be low cost, fairly complete, able to talk to the printer port. In addition, it should generate native code that can be run without the compiler or assembler. It should also run under the built in DOS and not require its own DOS. Printer Type of interface?, if he has the Epson, is that OK? What about the Apple printer(s)? Are there any major advantages to Apple printers over others? Editor Is the one that comes with the //c OK? Does one come with the Compiler(?) what is the best? Like most of us, he is on a budget, so price *IS* a consideration. As you can probably tell, I have no experience with Apple and would not like to suggest something inappropriate; that is why I posted here. I'm reasonably sure that there is at least one person in this group that already has a //c configured just this way. Again, the net would prefer that you mail responses directly to me, I will summarize to the net shortly. Thanx... - Steven M. Queriolo - AT&T Bell Laboratories - ...ihnp4!hlexa!smq - -- - Steven M.
