Tekwiki mentions the Oregon Analog ASM7 which does exactly that, although
I've never seen one, or heard of anyone having one.
Wonder what happened to it? (Pics under 7000 3rd party)

What you need is a Tektronix 127 for 7000 series plugins. Don't look, it
does not exist, I've never known why. Get a clapped out 7603 and use the
vertical signal out to get a single channel. For two or more channels

you

will have to roll your own but the schematic for the 7603 will tell you

how

(see board 6 "output signals"). Note that the 7000 series interface to
the plugins is much simpler is you don't need the readout. It can be a
connector from a PC XT (just the connector) and a few power supplies in
that you don't need all the trigger selector, chopping/alt logic. Bonne
chance and keep us posted. For many years I kept a 7904 in my university
lab to power two 7A22 plugins feeding my TDS744. From good advise on

this

site I now have 7A22s in my own 7603 but there are times when I'd like

the

processing of a modern digital scope.
