[comp.sys.amiga] C64 as a printer buffer

edward@ukecc.uky.csnet (Edward C. Bennett) (12/15/86)

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!

......................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.

    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.
