[comp.sys.atari.8bit] Multiple Modems

jdl47513@uxa.cso.uiuc.edu (Jason Lowe) (03/06/91)

I need some help with hooking up multiple modems to an atari 8-bit.  I was
hoping to do something like Diversi-Dial (tm) for the Apple.  I would need to
hook up 5 or more modems if possible.  The more the merrier.  As far as speed,
I probably would only need to handle 300 baud, maybe 1200 or more if the CPU
could take the punishment of all that data.  If anyone knows a relatively
economical way of doing this, please let me know.  Thanks!

if you know hardware hacking you could hookup a few 6552's to the system (read 
charlie hughs multi-PIA upgrade and base it off that....if you are making your own software then you could get two or three 800's link them thru joystick 3 and use 0-2 for a MPP/Supra modems in the 1000e series (foud for $10-$20 each...) 
this would be a good for 300 baud only tho'....another thing if you have a little 
cash is find a multi-serial card that hooks to the SCSI interface and get a black box or a MI/O (but you would need a company that would give the info for 
interfacing for it)

   I believe that some of the old MPP modems used to plug into the joystick
ports. With an 800 and an 850 interface (with 3 (?) modem ports) that will
give you a chance for 7. I believe I have seen ads for an Atari BBS to use
multiple MPP's.

I should have mentioned that I have an 800xl with Rambo upgrade and a 1200xl.
The idea of hooking MPP modems to the joystick ports sounds good though.
Possibly I could do that with my present 800xl or pick up a cheap 800.
I would rather do this with just my 800xl and take use of the Rambo upgrade.
This would be a multi-line chat system only, so 300 baud would be acceptable.
Hardly any disk access that I can forsee.  That would leave most of the time
to handle all that data streaming in from the modems.  Any other ideas?
Thanks in advance!
