This is my first time posting to this group and I have no experience with MIPS machines, so please forgive any blunders in the following: Does anyone out there have any experience with the MIPS RC3230 RISComputer? We are considering a RC3230 RISComputer running 8 users simultaeously off serial ports. What is the response time like ? ( I have the brochure benchmarks, but user opinion is always nice :-) ) Any problems with the hardware/software/support ? Any hidden costs/bottlenecks/problems? The configuration we are considering is: MIPS computer systems RC3230 RISCcomputer at 25 MHz R3010 Floating point processor at 25 MHz 64 KB of I&D caches 8 MB of main memory 2 serial ports SCSI controller 2 200 MB 3.5" disks (seagate drive) thick Ethernet interface TCP/IP and NFS networking software power supplies and cabling RISC/os 4.50 (UNIX SYS V.3.2) license Terminal(console), keyboard and line printer additional 8 MB of main memory 6013-N 120 MB,1/4" cart. tape drive ROS45B-MED RISC/os media ROS-00-DOC RISC/os documentation set 16 port serial I/O board. Any response will be appreciated. ( Assume I know nothing about the MIPS machine, but fairly conversant in UNIX and other technical details ) Please send via E-mail. -- .-----------------------------------------------------------------------------. | Richard Chan, Gellman.Hayward & Partners Ltd | | 33 Yonge St., Toronto, Ontario, Canada, M5E 1G4 Voice: (416)862-0430 | | UUCP:richard%ghp@mnetor.uucp | `-----------------------------------------------------------------------------'

8 users, and we have 24 Mb RAM. But it becomes rather piggish if anyone runs a job that uses lots of memory. So, if you were planning something awful like 8 users running a CAS, then you should invest in a lot more RAM since I/O can really bog this machine down it seems. Just one users experience.

You want more RAM than 8MB. You probably also should invest in one of these "intelligent" serial boards, and not use 8 separate ports on the AT bus (if that's what you intend to do) to lessen the interrupt load on the processor. Paul DuBois dubois@primate.wisc.edu

The 3230 takes (cheap) 3rd party SIMMS and so increasing the RAM is not a problem. Get the 8MB version and add all you can afford. -- Paul Bickerstaff Internet: pbickers@neon.chem.uidaho.edu Physics Dept., Univ. of Idaho Phone: (208) 885 6809 Moscow ID 83843, USA FAX: (208) 885 6173
