With the Z50Bus being based around a dual-row 50-pin connector, laying out a fast prototype of perf-board is no problem. But wouldn’t it be nice to not have to deal with the wiring complexity of a dual-row 2.54mm pitch connector? Now that’s no problem at all, using this prototyping card designed specifically for use with Z50Bus compatible systems!
This prototyping card is made specifically for making prototypes versions and homebrew expansions for Z50Bus based microcomputers. It provides a main prototyping area of 27 by 37 individual pads on a standard 2.54mm grid, plus an additional grid of 9 by 5 pads. Examples of use for the small extra area includes location of connectors to external devices, power regulation circuits, support circuitry or indicator lights, to name just a few.
The 50-pin bus connector is broken out on easily accessible connection points, providing two connecting pads per signal. All pads are fully though-plated, and the board is finished in a Hot-Air solder level (HASL) finish, making soldering a breeze, while at the same time protecting the pads against corrosion and oxidation.
The card has outer dimensions of 100x100mm, the base size for Z50Bus expansion cards.
The card will be available for order both as bare PCB, or as PCB with 2×25 right-angled header connector included.
