Microbee connected to expansion box383 viewsThe main BeeBoard expansion board connected via 2 cables - the normal Microbee expansion connection and a smaller connector from a 2nd Beeboard Clock Board that was installed inside the Microbee case. You can also see some mods to the core board (yellow wires) that were part of the BeeBoard installation

Expansion Box406 viewsA custom built box made from galvanised steel and painted matt black (nice!). Power supply on the left, BeeBoard on the right. The Beeboard included extra serial and parallel ports, which I presented thru the usual D connections on the front panel. The serial port chips were never installed or wired. The small veroboard at the right was a mod/fix of some kind but can't remember exactly what it did...yet

Power Supply415 viewsA custom built power supply that ran the Microbee, Beeboard and 5.25" floppy drive. The large transformer was also custom built and hand wound! There are some hefty heatsinks on the back panel which can't be seen here. It was a simple set of separate linear power supplies, one for each of the voltages needed and running from multiple transformer windings.

The MegaBee daughter card is also installed at the right, with cabling running externally to the MegaBee unit for now. Currently waiting on parts so that the MegaBee can be permanently installed in here too
