DEC Alpha 3000 and OpenVMS 8.4

[Douglas Taylor via cctalk]

I'm trying to bring up an Alpha machine, a 3000-300, the hardware is 
working fine, but I have some questions-

The system disk is an RZ26 (1.06GB) and I installed the OS and one 
layered product and the disk is full.  How much disk space is needed for 
8.4?

There is a power regulator next to the CPU chip and it runs pretty hot, 
I measured the heat sink at 140 deg F.  Is this normal?  The chip is LT 
1083 CP.

Can I use 68 pin SCSI drives in this computer, is there an adapter to go 
from 68 to 50 pins that would work?
