    Guys,

    I have a mate down the road who was also a teenage Atmos fan.
    His claim to fame is going as far as humanly possible on Spooky Mansion on the Oric, ie. screen 2.

    He always maintained that Hans Christian Anderson must have written the blurb for the game and that the other further screens must be work of fiction as it's impossible to venture any further with the fiddly controls inherent in the game!

    Any road, I digress.

    Johnny's been in touch this morning to say that AT LAST, he's dug his Atmos out the back of his wardrobe and lo and behold...a section of his keyboard doesn't work.

    I've had a quick shufty, had the bonnet/lid off and removed some dust in there, had the keycaps off and detached the keyboard/reconnected just in case of flaky connections...no cigar still.

    The keyboard area mysteriously not working (8 keys in total: J,K,N,M,<,> and the cursor arrows for UP and RIGHT) is located in the bottom right hand section of the keyboard:

    Looking at the service manual it states (and I quote):

    "A faulty ROW of keys producing no characters points to IC1 or pin connections (possibly IC6 but unlikely)....a faulty COLUMN is likely to be due to a bad connection on PL3 which connects with the (AY) sound circuit (IC4)"

    Rich, this is beyond my manual delvings, pokings, reseatings and cleanings.

    Is there a chance you could have a look at Johnny H's Atmos at some point, mate?

    Naturally, I will pay the postage there and back and pay for any parts required/your time taken, buddy.

    Johnny will see me right, he says, by re-writing Oric gaming history and finally demonstrate to me him completing Spooky Mansion!!



    Cheers in advance if you can assist, fella.

    The fix is easy, turn it off and put it back in the cupboard...

    Send it up to me Andy and I’ll sort it. Sounds like the keyboard PCB rather than the 6522A and/or AY. Did he say what he was doing prior to it going wrong?

    Many thanks, Rich.

    I will get on with this toot sweet.

    No, long period of inactivity at the back of the wardrobe I'm afraid.

    He can't remember the last time he used it - possibly 2-3 years ago, maybe more.

    Cheers, Rich - have a good day, guys.

    Looks like it’s due to arrive today Andy, so I’ll be able to get cracking on Monday.

    Fab news, Rich.

    I do hope it's something simple and not requiring any obscure/rare to source/expensive parts.

    I have my fingers (and now tentacles thanks to Covid jab) crossed, fella!

    Oric is fixed Andy, Keyboard PCB had broken tracks so needed some remedial bodges with Kynar wire to restore the connections.
    The number 7 key was also giving problems with the contact leaf springs so they needed some fettling. The number 7 key will likely have problems in the future as the leafs eventually stop making good contact and will need the process repeating.
    The keyboard PCB is starting to degrade and although all the other contacts are sound now there is a likely chance that at some point another will fail. It’s the copper tracks themselves that are breaking so there isn’t a lot more we can do other than fix them as and when.
    I’ll replace the Electrolytic capacitors and voltage regulator as part of the 35 year service :)

    Good news was it wasn’t the AY or VIA.

    WAHAY!

    A special Oric Atmos ZAP, PING and SHOOT for Richie as he gets Johnny's keyboard to EXPLODE back into life.
    I've just text Johnny and told him to stop storing it in the wardrobe and give it some proper use but to go steady as the repair is as good as we can give it for now and maybe, in the future, he will need a new Stackpole keyboard, Rich?

    I know, from time to time, they come on Ebay as I believe Tandy/Radio Shack used to stock them as spares.

    Once more, a thousand ZAPs and PINGs from me and Johnny, Rich.

    You never know, if we get him really interested once more, he might well join us on here!

    Mate, let me know how much I owe you and he'll see me right (when he gets his glasses, naturally).

    Cheers, Rich.

    I have an update for Oric fashion fanatics shortly... watch this space.
