Here is a page scan and the text from a 1978 PAiA catalog. The PVI appears
to be Don Lancaster's TVT-6.

Don Lancaster's ingenious design provides software controllable options
including:
Scrolling
Over 2K on-screen characters with only 3MHz bandwidth
Full performance cursor
Variety of line/character formats including 16/32, 16/64 even 32/64
User selectable line lengths
You'll want to see the operational details on this first. The PVI-1K is not
the universal answer to every video display requirement. In applications
where its minor limitations present in?surmountable obstacles to a design,
more expensive techniques should be used. If you are in doubt, the PVI is
completely described in the July and August, 1977 issues of Popular
Electronics. Reprints of these articles are the instruction set for this kit
and are available separately for $2.00 postpaid refundable upon purchase of
the PVI kit.
Complete kit includes circuit board, all parts and instructions and is
available in either of two forms.
PVI-KM Ready to go with KIM's $34.95 wt. 1 lb.
PVI-MT For other processors
(requires PROM coding) $34.95 wt. 1 lb.
