    Default Atom bits, Master 512 card

    Hello all, I'm offering for sale the following Acorn items. All prices include postage and package to the UK.

    Master 512 co-processor

    This is a recent eBay purchase that I've had second thoughts about since winning the auction. It's just the card on its own, no manuals or discs are included. I haven't tested it other than by turning on the computer with the board installed, and the board is recognised. The previous owner stated that it was working fine, and I have no reason to doubt this.




    The asking price for this is 63, which is the same amount I paid when buying from eBay.

    Atom technical reference manual and circuit diagram

    The manual is in decent condition for its age, though there are some pencil markings on some of the pages (I assume that the previous owner marked things down as they built the computer). The circuit diagram appears to be unmarked.




    5 for both.

    SOLD - to sir_beaker


    Atom power supply

    This is an original 8V power supply for an Atom, with UK mains plug. Sold untested, though it was outputting the required voltage when hooked up to a multimeter.

    Timedata RAM board for Atom

    This is a RAM expansion for the Atom, which plugs into PL7. it consists of a larger board with a number of 4116 RAM chips, plus a smaller power board that sits on top and which has a connection to the Atom's DC power socket (the blue wire, which will need extending by the new owner). This comes complete with manuals, the bolts that secure both boards together and a host of wire links that you have to add to the PCB in various IC sockets (this is detailed in the manual). Not tested, but the previous owner of my Atom had pictures of the computer working, so I assume all is well.

    I will also include a video RAM expansion for the Atom - I don't know what it does or where it goes and I don't have any manuals for it.






    Asking price for this is 25.

    Sorry, internet's been terrible tonight. Could I just take the Atom power supply and technical manuals/circuit diagram. It turns out I already have the 32k expansion so someone else might appreciate that. I'll PM you now

    Can this thread be closed now, please? I'd like to try to sell elsewhere.
