[comp.sys.mac.hardware] Help... need more serial ports

chai@hawk.cs.ukans.edu (Ian Chai) (04/20/91)

I have an old Mac 512/e with 2 megs and a 5meg IIx, and an Imagewriter
II and a modem. I sometimes use the IIx's HD from the 512/e with one
of the public domain Appleshare-compatible file servers, as well as
play multi-player games using Appletalk. I keep the printer and modem
hooked up to the IIx since that's where I do my serious work.

Problem: the IIx now needs 3 serial ports: one for printer, one for
modem and one for Appletalk...

Any suggestions? Currently, I'm manually unplugging things, not an
easy task as the machines have a wall backing them and so groping around
the back for the cables is no fun.

Will a switch box mess up appletalk? I have yet to want to run apple
talk and the modem at the same time so I have the modem using the
printer port and the printer using the modem port...

Thanks in advance.

This is the second time I have seen this problem (i.e. too few seriel ports)
come up.  Here is a solution, which I have mailed to people before.  If you
have a Mac II series, you can buy Quadralink from Applied Engineering for 
about $210 through mail order.

	try Mac Connnection for a good mail order price....

				Hope you work it out...

 Does this really exist? I've never heard of anyone who has one, and I have
 not received a response to a letter I sent to AE requesting information on
 the Quadralink.

 If anyone does have one, I'd like to know if this is possible 
 under -> 6.0.7 <- :

 o Appletalk out the printer port.

 o Modem on the modem port using Microphone II.

 o Imagewriter II on a Quadralink port.

 o MacRecorder on a Quadralink port.

 This all might be in use at the same time. Considering that most programs
 hardcode the modem and printer ports, will this work?

The QuadraLink serial expansion board is a nifty piece of
hardware that provides four more serial ports for NuBus equipped
Macs. The QuadraLink cdev allows you to "shadow" one of the QL
ports to either the printer or modem port. This still limits
you to two active serial ports at a time. Apps that recognize
the card can have all ports going at the same time (great for BBS's).

The QL init software creates eight I/O drivers for each QL card
that it finds (four input, four output). If you want to open a
serial port on the card, and you know the card is in slot $C, then
the output driver name would be "QuadraLink Port 1OutC" and the
input driver name would be "QuadraLink Port 1InC". The "1" is the
port number (from 1 to 4) and "C" is the slot number (from 9 to E).

Finding the card is a simple matter of examining the NuBus slot
resources and looking for the name "QuadraLink"

Hope this helps...

DOES QuadraLink for AE (Applied Engineering) exist???????

I hope so, or many mail order firms are using false advertising !!
from my most recent Mac Zone catalog...

"   QUADRALINK
	QuadraLink is Applied Engineering's answer to clogged serial ports.
	With the proliferation of popular serial devices, printers, scanners,
	digitizers, plotters, modems, graphicas tablets and the like, comes
	the need to control several serial ports simultaneously.  QuadraLink
	is fully compatible with the Mac's Communication ToolBox and System 7.0
	(when released).  For older software, the QuadraLink package includes
	software to create a "Shadow Driver" so its serial ports will be 
	recognized by the older software.  Like the Mac II's existing serial
	ports, QuadraLink's four serial ports are standard Mini-8 DIN connectors
	QuadraLink carries a full five year warranty. Manufacturer: Applied
	Engineering

List $299.................Zone $204 "

(end of quote, not responsible for typo's, sorry)

Now, this product is also advertized in MacUser/MacWorld Issues by
	MacConnection, MacProducts, MacAvenue, and others....

I do believe that it is in current production.  I was talking to a fellow
"Macaholic" who said that he was runnig two printers and a scanner through
this card successfully.  He was a mutal friend (and silly me can't remember
his name...?) of a friend.  This was about 3 months ago...

I have not delt directly with AE for about 3 years now (after I gave up 
my Apple //e) so I can not give further info on their tech support or 
current helpfulness...

					Good luck... Greg ("Carpedium")

 Companies were advertising Vette! long before it was available.
