MicroVAX 3100 M10

So I just got my new MicroVAX 3100 M10 all cleaned up, and I removed the memory boards, there are two, they hook together and are labeled "4/8 MB Memory Option"... My question is which is it? 4mb or 8mb? ;) Anyone have any more info on these machines, I guess my previous question about would a logging server/writing logs to tape machine be underkill for this machine is definitely no? Are there any RAM upgrades readily available for these? I think 16mb+ (ftpd, telnetd, nfs) would be needed for my purposes? Also, anyone have an MMJ->DB9/25 adapter (that doesn't require an MMJ cable, or at least include it) for sale? Lastly, can this machine take any SCSI hard drive? Right now it has a 50 pin RZ26-E in it, that is 1.05gb right? I am pretty sure it is dead. Any help is greatly appreciated! -------- Thanks, Torquil MacCorkle, III Lexington, Virginia
