its photo, how about these? ?They look like HP cabinets, but I didn't
feel like digging them out to look closer, just snapped a photo.

Tektronix workstations of the 4110 or 4120 vintage. In the 1984 to
1987 Tek catalogs. This is the deskside case, not the pedestal. The
front of the deskside case pulls out and shows the two 8 inch floppys.
A side comes off to get to the card cage I seem to remember.
The M4115B was 8086 based and the M4125 series were 80286 based. These
were often upgraded and the upgrade path is shown in the 1985 catalog.
So when you find one it can have all kinds of cards in it. Up to 8
planes of graphics were available.
I have seen a 80386 processor card and also a graphics card called a
Rainbow that were in a maxed out one. Both rare cards.
In the 90s we went through quite a few of these workstations.
Unfortunately they are heavy aluminum cases and heavy circuit cards
and of great value to the scrappers.
I noted that the model number appears different with the one on the
left being longer than the one on the right. The actual configuration
of the machine is usually on a plate on the back....although, as
mentioned, many were upgraded.
