I think it's got 3 (4 if you count the slot with the processor, do you count that?). The downside is I think all my memory cables are for KA630's. I know the one on the KA650 can only handle two memory boards. With 3 8MB boards, I'd like to use them all. Of course a pair of 32MB boards would be even better :^) The big problem is I want to run OpenVMS 7.2, DECnet, TCPIP on it (NOT CMUIP though), and have it as part of my Cluster. I suspect 16MB really isn't enough for running DECnet and TCPIP 5.0, though I've heard of people running TCP/IP on 16MB machines. Hmmm, if one of the other machines in the cluster is running TCP/IP, can the disks on the MV3 be accessed via that machine? Guess I'd better look into that, if that will work, I don't need TCPIP on this system. Zane

If you can get *any* kind of performance while running all that (I'd forgotten you were running the DW/Motif) I guess I don't need to worry about a 16MB machine. Basically all the system is going to be doing is activing as a Archive and will only be accessed by machines on my home network. I've not been worried about processing power, just that I'll have enough RAM to get acceptable preformance under V7.2. Same config can handle VMS 5.5-2. I was tempted to go with 5.5-2, and one of the 3rd Party TCP/IP stacks on the Hobbyist program, but would prefer to keep my Cluster in a "Supported" configuration. You can cluster in 5.5-2, but only clusters of V6.2 - 7.2-1 are supported. What can I say, I admit it, I like being able to run "MONITOR CLUSTER" :^) Well.... a LOT of that is because you're running on VAX hardware. I've found that I don't get decent performance on my Alpha's when running with the minimum of 64MB, really need 96MB or more RAM in a Alpha to get good performance under OpenVMS. I've heard from a friend that attempted it that V7.2 won't install without a minimum of 64MB in the system. Zane | Zane H.
