I picked up the M01 scope and took it over to the VintageTEK museum for a
closer look. It turns out that before the 7000 series got its name Tek
developed two products called the L01 and the M01. The M01 was a 4 slot
scope like the later 7704. The L01 was a 3 slot scope like the later 7603.
These were a nightmare to build. Almost everything was hand wired. The
harmonica connectors had been developed but they were hand wired rather than
using ribbon cable. The wires ended at hand soldered pins mounted in the
chassis walls.
This particular M01 scope is serial A11 which means it is an A-phase
prototype. After A-phase comes B phase, and then production. It came with an
engineering prototype of what would ultimately become the 7B71 Delaying Time
base in it. This was unusual because it used round pushbuttons for the
triggering selection and not the square ones that finally made it into
production.

Probably an engineering "hack" that needed most of a scope to test something
else, or a production test fixture. The front panel looks like it was
actually anodized with the lettering, so it might have been a production
test fixture that they needed more than one of.
The seller is from Portland, so either they worked at Tek, or bought it from
the company surplus store. These sort of test fixtures and engineering
hacks showed up in the store often 20 years ago.

Close to a 7504 or 7704. Early prototype?

Anyone know what a Tek type M01 'scope is? Ebay item #350714574978.
Thanks,
