In fulfilling Kerm's Christmas wish for a TI CBL, I noticed the unit I purchased had an unusually early date code. I had to disassemble it anyways to clean out some rather nasty battery leakage, and noticed there were hand-soldered wires between the mainboard and a daughterboard inserted after the initial production.
The CBL in question has date code LTA1995 (Lubbock, TX, USA | Week 19 (May 7th thru May 13th) of 1995) and serial number 10004923. It runs ROM version 5 (Command 7 first element returns 1.0500), whereas my production CBL from 1998 runs ROM version 6.
The complete album of board pictures can be found here (~70MB).

). I notice that the bodge board, as Jonimus put it, seems to be connected to a part labelled AD7776..., which appears to be a family of high-speed multichannel 10-bit ADCs. I also see two transistors, two 100K ohm resistors, and a light-blue component that I can't identify.
