[OZAPRS] Small GPS

[Damien Gardner Jnr]

Man, I still have my Microprofessor sitting on the shelf here :)

And an alfoil-covered sheet of polystyrene with quite an assortment of z80 cpu's, PIO's, SIO's, 2764's, 2864's, and 6116's :)  Oh, and the old TE eprom programmer I built, and then had to write the programming software for, for it!

I fired the old bugger up a few months ago, and she still ran quite happily!  Took me a while to remember how to program it though!

I didn't think anyone remembered the microBee, let alone the keys :( I had 3 complete units, Kitset Rom, 32K Rom and dual floppy, complete with one  green and an amber monitor. Ran Packet on it right up to 2002. Sadly the building I had them stored in burnt to the ground. That happens in "The Bush"!  :(
