Re: Electron User Mini Office

Hi all. Can someone kindly transfer Mini Office to disk and upload it. I could not find it anywhere. Thanks I have the Mini-Office PCB with all 4 x ROM on-board. It would, probably, work in the Electron if someone could get it to work in Mode 6 - as opposed to Mode 7 where you can't control the cur...

P.S.: Keep the fingers crossed that the ULA is still alive. All the rest I can fix.
Even if the ULA is goosed - we can fix short term (a loan ULA) and long term read this thread :D

Re: Acorn Newbie

Welcome to the Forum, Eratosthenes . . . (had to look the name up!) Elejoy . . . So, can you leave your Electron switched on overnight now? A real test of your ULA contact cleaning :D There's lots to add-on and now, if you're interested in Games, you don't need a tape recorder or a Plus 1 . Dave H :D

A3000 RISCOS ROMs or ROM images wanted

I've just completed refurbing my 'house' A3000 that had died. All stripped down, including the keyboard - in the dishwasher :mrgreen: everything came out sparkling (didn't put the keyboard metal plate, polymer or PSU in there [-X ).
