IBC 386:120 runs SCO Xenix 2.3.1 GT Version (SCSI) and 2.3.2 will be out in a few weeks. 2. The machine is not an AT clone, but a 386 proprietary system with all SCSI controller to acheive maximum performance for up to 120 users. 3. We have tested > 20 users with NO problems, and have talked to users running 68 users. 4. Timing tests we ran vs a IBM PS/2 Model 80 - 20mhz machine and an IBC 386:120 25Mhz machine with 8mb ram, and 4mb disk buffer running a 614 mb drive with both systems load with the same software. Open Systems (OSAS) File Space report ran 15 minutes on the PS/2 and only 6 minutes on the IBC. The machine does what it is supposed to do, and Recognition does Nationwide service, providing next day Fed Ex 1 replacement of entire system if needed... -- .. Computer Consulting Service ..
