[comp.unix.i386] 32 Port Cards for AT&T 6386

john@vsi.COM (John Koontz) (12/09/89)

A customer of ours has a need to hang over 80 serial ports on an AT&T 
6386 (25 or 33MHz running SVR3.2) but there will probably be no more than
20 concurent users (light word processing stuff).  AT&T should be shipping
their IPC1600 pretty soon, but they won't support more than 4 cards per
machine.

Does anyone have any experience with 32 (or more) port cards on 6386s?  
As expected, I'm concerned about the reliability of any non-supported
card.

Thanks for any help.

     No, but...

     I've had extremely good luck with the Equinox Megaport board.  I run
     mine under Interactive Unix 2.0.2.  Each board has 24 ports and I
     believe 6 boards are supported for each machine under unix.  No
     interrupts are used either.

     I run a host of devices on it including fast Trailbalzer bidirectional
     uucp transfers with no problems.

     In looking at the label on the device driver floppy it says:

     UNIX System V/386 Device Driver Release 1.7.0

     ...compatible with UNIX 3.2 form AT&T, Dell, Everex, Interactive, SCO 
     etc.  (the "etc." is theirs not mine)

     I got mine from Continental Computer Systems in Newington, CT.
     1-203-665-1355. Equinox is at 1-305-255-3500 (they sent me to CCS).

     Hope this helps!
