The T2011 is a Ka62A (the CPU for a VAX 6000-200); unless it is really one of
these:
	T2011-YA: VAXserver 6000-200 CPU
	T2011-YB: VAX 6000-300 CPU
	T2011-YC: VAXserver 6000-300 CPU

The T2022 is a KDM70 disk/tape controller (XMI version of the KDB50/KDA50);
with a microcode change it becomes the KCM44, which I think is a ciontroller
for those gapless tape drives the oil industry like(s/d) to use.

The DECsystem 5800 CPU board set would be  the T2025 and T2026.
