The Tek DPO, based on the 7704 (or possibly the 7704A) was the first AFAIK.
That would be the Tektronix 7D20 (as a combined timebase/dual channel
scope) which was intended to run at least in the 760x series.
I think he means the Tektronix P7001 which attaches to a 7704A between
the display and mainframe:
Then there was the magnificent 7854. IMO, this is the BEST lab 'scope
ever made. It is still my 'scope of choice.
and I'd like to have one, but that's still out there, somewhere.....
The downfall of both of these units was the relatively slow A/D by modern
standards.
10 MHz bandwidth for the 468, and about 70 Mhz bandwidth for the 7D20
(IIRC).
The 7D20 uses a CCD based sampler like the 2430 series of DSOs.
