drives: 2 * 5.25",  3 * 3.5"
power rating depends hard on the cpu & memory. but it is a big case :-)

I got this numbers from the dec site. (without thinking) after fiddling a
little around, i figuered out that must be a typo on the web-site, cause: 

MV3100 M10e: 30 tps
VS3100 M38  : 30 tps

MV3100 M20e: 22 tps
VS3100 M48 : 30 tps.

And as we learned from Michael Sokolov ( THANKS ANYWAY !!!) this are nearly
same machines ....

this is probably one of the marketing jokes. they (DEC) probably measured
the performance with the optional second SCSI-controller. (an option in the
bigger cases ...)

YES. IT'S A TYPO. (fingers faster than the brain. have to use a vax-chip
..:-))


anyway, keep it up. is a very good work. cause i was a long time on the
other side, (MIPS, and PC) it seems i missed a lot. 

cheers,
