ZX ExpBoard
ZX ExpBoard is a ZX Spectrum bus expansion board containing two (for
the ExpBoard 2) or three
(for the ExpBoard 3) slots for cards equipped with pin header
(square pins). Moreover, the ZX
ExpBoard is pass-thru, so it is possible to attach an interface with
a classic edge connector .
ZX ExpBoard is aimed at developers, both Hardware and Software, but
it is useful for anybody who
wants to connect many interfaces to their Speccy at the same time.
Pin header usage has its benefits in low price and good electrical
contact between the card and the bus
expansion board. The same card can be equipped either with pin
header (prototype) or edge connector
(final version) without changing the PCB layout.
There are one or two (depending on the version) positions for
soldering additional capacitors to +5V
power as well.
