HP Apollo Series 400

Today I found several HP Apollo Series 400 Computers headed for the dumpster. These were used as I think some sort of Servers for a medical facility. There were 20 or 30 of them I only took 5.. Opened them up and they each have a SCSI hard drive and I think 32MB RAM, However they have no Floppy drive, ISA or PCI slots in them.. They support 3 serial ports, Parallel Port, SCSI Port, Kybd, Standard Network Interfaces, and Audio In and Audio Out.. They have a place for a second SCSI drive also in them. The Processor looks to be a Motorola 68040 I think.. I hooked up my VGA monitor and powered up , but it appears to be out of sync, or a non-standard VGA out put. I could see part of a color screen, but the screen seemed out of sync and not really readable. Does anyone know what these are ?, And other than parts are they worth anything.? Can I do anything usefull with them.. ? Thanks, Phil
