Hi! Someone here suggested that I ask for suggestions as to how to value
some TG16 prototypes. These may be available for sale, but for now I am
primarily interested in how to value these for insurance purposes.

Here is a short list of recently re-uncovered (OK, safely stored away for my
future gaming room) prototypes and premasters for the TurboGrafx 16, which
is my second most favorite platform. (First being the PCEngine, so there.)

Premaster and Prototypes US TurboGrafx CDs

These are all burned. They are the original and legitimate programmers'
proto/beta/premaster, and all have various "Sharpie" markings on them.
Some Jewel cases have stickers on them. What's the difference between
a prototype and a premaster and a beta? I have no idea. These were all
purchased from employees at Viacom, and are on very obviously old single
to quad speed green or blue media. To my knowledge, I am the original
owner of these prototypes, following Viacom, and they have NOT been
duped or archived, so no other known copies of these versions exist.

Prototype Hucard - These are long green diving boards with EPROMs
erupting from the tops. They are all official NEC boards, with the
appropriate logos and silkscreen artwork for the PCB.

I've noted the date markings on the top of the EPROMs for reference.

Thanks!
