SD Systems Z80 Starter Kit
A nice clean example of this board, which I managed to get for quite a good price; they can often be very expensive.
Apart from a few badly inserted chips (bent legs), a broken off crystal oscillator and some minor soldering issues, this board was supplied in excellent condition. Particularly notable is the clean user expansion area, which can often be full of old wire-wrapped connectors. the two S-100 bus connections are also non wire-wrap, and the board comes complete with 2K of RAM (though the unbranded grey 2102 chips in the expansion area are of rather suspect quality).
This board also has my own utility ROM fitted, which provides convenient test routines and some simple demos. It highlighted a problem in one of the grey 2102 RAM chips, which I have now replaced with a spare one that came with the board.
