My two System 80's are going good. I had the keyboard units recapped but not the expansion units. The cassette model is my own machine the other is the business model, I had to put in 32k of ram chips and a new z80 chip for it to work. Long gone are the 51/4" drives instead I use a 10to 12 twist on the ribbon cable with 31/2" standard PC drives. Also gone is the old drive power supplies now using that small 5v chinese brick. I still use my DSmith B&W screen but the System 80 gives a great display on an LCD Digitor TV screen. My Colour Genies are up and running the Gnomic Wizard disk interface is the same as the P1000 except they add an extra small board to contain a loader ROM. My chips also have the numbers sraped off them.I use Microdos in both the System 80/Colour Genie and my own loaders with m/c games.
