Ti-99/4A Console Tester Interest Check

[Shift838]

This is a poll to gauge interest in the reproduction of the Console Tester originally designed by Geoff Trott.  Dan Eicher has been kind enough to loan me this tester to reverse engineer.  I would like to find out how many people may find this tester useful for dead or failing 99/4A consoles.

Is this tester similar to the official TI RAMtrap device listed in their service manual which includes the schematics for it.

Not sure, but I know this one was published back in the 80s with schematics.  I did find a few errors on the schematics to what the actual board is though.

This test VDP, RAM, GROMs, etc..
