Re: A3020 Welcome Surprises

Thanks for the input, an update: It's an '93-AGB23-' serial number (2Mb + 60Mb HDD apparently). With a modern LCD monitor the flashing when on the desktop has gone (Mode 27 VGA was auto-detected). When trying to run games I got an 'unsupported resolution' error from the monitor (I presume this res w...

A3020 Welcome Surprises

Hi All, Some time ago I obtained an A3020, and despite spotting corrosion on the battery managed to neglect it until tonight (I know - tut tut!). The reason was mostly the lack of time to strip the thing apart and deal with it - it looked quite a job. I found helpful guidance to one of my old thread...

Hi All,

I have an interest in acquiring an original (unmolested) cheese wedge Teletext adapter, preferably one that was known to work.

If anybody has one they want to part with, please let me know.

Re: The most faithful Donkey Kong home version ever!

This reminds me almost exactly of 'The King' for the Dragon 32 by Tom Mix (called 'Donkey King' for the CoCo). The graphics are a bit better - a few more colours and animations, the sound has more fidelity but the overall feel is the same. The gameplay (including movement of sprites) and screen orde...

Re: Kensington locking a Beeb?

Thanks Ian,

I was thinking about the plinth as well which should be fine as long as I can drill a suitable hole. The Beeb might need the plate, but I'd prefer it to look neat rather than untidy. I need to think about that.

Re: A3020 help

Thanks for the replies. As it appears so involved (and I want to take my time), I'll need to wait until I have enough time to look at it.

If I wanted to replace the battery with a non-rechargable type, would this be an option and does it matter what kind of diode I would need?

The monitor type on the Arcs is quite simple. Usually you can simply get away with holding down the 4 key on the keypad at power on to select a SVGA monitor type. Sometimes this doesn't work though at which point you have to do the following process... 1. Hold 'T' down at power on. (This selects in...

The A7000 worked first time with a HP Compaq LA2205wg, the A3020 I'm not so sure about having randomly tried SHIFT R & SHIFT D in a vain attempt get it working.
