Greetings.... Looking for some details on the IBM 4331 series of mini computer... Like 1. What OS is used..? 2. How many users...? 3. Object compatible with s/370. 4. Size of the computer. 5. Processing power in MIPs or processor speed. 6. DASD units 7. Any other info Also going to network this with PC's...any suggestions hints...?? Thankx in advance Ali p.s I'll appreciate if you can send me a quick respone.

Depending on the 31 model number you get, you may not really want to run MVS. > 2. How many users...? It really depends on your application. > 3. Object compatible with s/370. Yes. > 4. Size of the computer. 6'x3'x6', give or take a little. I've never really gotten a yardstick out to measure our '81, but the '31 is comparible in size. > 5. Processing power in MIPs or processor speed. Again, depends on the model number. I believe up to 2.4. > 6. DASD units 3380's, 3375's; I'm not sure on the 3390's, I suppose it really depends on the disk control unit you get. >Also going to network this with PC's...any suggestions hints...?? PC-Mainframe, from CR-Software. Its a really nice package, and only runs about $10k. MD -- -- Michael P.

MVS would probably run, but very slowly...which is a redundant statement. > 2. How many users...? Depends on the workload. It's not fast or big, but for small card-wolloper shops it was a good machine for its day. > 3. Object compatible with s/370. It *is* a member of the s/370 architecture line. With a few machine- specific features (and excluding XA and ESA goodies) the S/370, 43xx, 937x, 303x, 308x, 3090, and now S/390 all share the same basic architecture and binary compatibility. > 4. Size of the computer. In what terms? The machine type (4331) says only what basic electronic design was used. Model numbers are used to distinguish CPU speed and memory sizes. Some representative numbers: Model Memory (MB) range Max channels MIPS Max channel speed 4331-1 .5 - 1.0 ? .25 .5 MB/sec 4331-11 1 - 4 2 .38 1.25 MB/sec 4331-2 1 - 4 4 .50 1.86 MB/sec > 5. Processing power in MIPs or processor speed. See above. > 6. DASD units Whatever DASD would fit the rather anemic channel speed limitations. My notes say that 3310, 3350, and (for the -2) 3370/3375 would work. > 7. Any other info The boxes included optional under-the-covers TP interface options and maybe an integrated disk controller as well. >Also going to network this with PC's...any suggestions hints...?? Why? The unit is an antique, and for a trivial amount of money you can get newer, more powerful IBM boxes from brokers. A 4381-P2, for example, is listed as available for $13,500: it's got a MIPS rating (whatever that's really worth) of 2.8 with 8 MB of memory and 3 MB/sec channels. Smaller machines are available for what seems to be little more than shipping cost. Joe Morris
