I'm contemplating a project using a upd6145 "SPI interfaced On-Screen
Display" chip. If I have the era right, it's from about 1993, and
would have been used inside TVs and VCRs to crate menu/overlay text
for setting preferences. There's one on eBay right now, but I hate to
do this kind of work with one chip and no spares. Also, I can't seem
to find the specs on it. There is at least one project out there
using it, so I could probably determine all the pins from where it
fits in the circuit, but a datasheet is always handy.
So... before I dig too deeply, does anyone here know of a vendor that
might have 2-3 of these? I'd probably settle for a brand/model number
for a sighting if anyone happens to be into TV guts.
Thanks for any pointers,
