My brother recently upgraded from a C64 to an Amiga. Trouble is, his C64 printer won't work with an Amiga, so we want to set up the C64 as a printer buffer. The big hurdle in doing this is converting the C64's serial port to RS-232. We want to build our own converter to do this. Has anyone out there built their own RS-232 adapter? We've got the basics figured out. We have a 1488/1489 set. We can see how to power them. But we're getting confused on which pins of the CIA chip to use. Another thing, how does the Amiga do hardware handshaking? CD? DTR? RTS/CTS? (I don't have his manuals so I can't look for myself.) Any and all help will be greatly appreciated! -- Edward C.

......................C64 as an Amiga Periferal...................... .....Check out the December (?) (I just loaned my copy out to someone so I can't check it) issue of Computer Shopper. There is a first instalment on an article to give detailed directions on how to build a hardware interface to allow using a C64 as a printer buffer, or for other forms of communicating with the Amiga. This could be a great boon to many an 'C64 upgrader' such as myself. Bob Dickow (UUCB!egg-id!ui3!dickow)

This could be a great boon to many an > 'C64 upgrader' such as myself. as it happens, the same ish of 'shopper contains the second of three(?) installments of an article about interfacing a C64 (or amiga!) to an ibm pc via parallel port. i heard long ago that the pc's parallel port was an inch away from being bidirectional, but never tried to close that gap. this article has instructions for making the modification, and it seems nearly trivial even to a h/w neophyte like me (disconnect one pin from ground, jumper it to unused pin on another chip). since i have an AT handy, i'm going to try my hand at building a homebrew turbo-sidecar. wayne hamilton U of Il and US Army Corps of Engineers CERL UUCP: {ihnp4,pur-ee,convex}!uiucdcs!uiucuxc!hamilton ARPA: hamilton%uiucuxc@a.cs.uiuc.edu USMail: Box 476, Urbana, IL 61801 CSNET: hamilton%uiucuxc@uiuc.csnet Phone: (217)333-8703 CIS: [73047,544] PLink: w hamilton
