Some duplicates and extras I've ended up with; free shipping to AVICC, can take payment either via PayPal (friends and family) or ChipPay.

A: Naval video amplifier board from some mid-80's system, with an opened hybrid module - $10
B: sold Intel MD87C51 military version of EPROM microcontroller, part of a frequency synthesizer in an aircraft radio system - $10
C: Mystery Russian board, fairly modern (1999) with an interesting mix of parts. Large black DIP package is Intel TP82510 serial interface controller, some Western AC-series digital logic in plastic SOICs, 8x classic Russian ceramic-and-gold packages (haven't ID'ed the part numbers yet), and a crystal inside a glass jar - $80
