History

Not much to say yet about this box. Obtained it from another collector's surplus. Unfortunately the battery chip (Dallas) seems to be empty, so the box doesn't remember its boot device across power cycles. Apart from that it works perfectly and I may use it as a reference machine between the 3100/M76 and the 4000/90

Battery

Unfortunately the VS4000/60 is one of those machines with the god-awful DS1287 clock chip, which is difficult to find and replace once it is empty. In this case the machine will forget its time and also its boot device, so it falls back to network boot (ESA0). One has to manually specify 
set boot dka0 ! for SCSI disk 0
boot
! or:
boot dka0     ! for SCSI disk 0

CD-ROM

The following CD-ROM drives booted VMS successfully: 
Plextor PX-32TSi
Toshiba XM-6201B 
Toshiba XM-5301B

RAM

The 4000/60 comes with 8MB onboard RAM. It has 6 additional slots to be populated with either 4MB or 16MB RAM modules, to maximum of 104MB. The 4MB ones are the same as for the VAXstation 3176. Take care they sit correctly in their sockets: insert them first with an angle of around 45 degrees and press them firmly into their sockets until they're in upright position. It has happened to me that a fully loaded system was reported has having 104MB, but the RAM tested failed due to badly connected RAM modules.
