Vintage Computer Fest - Mountain View, California - Aug 4-5

Acorn computers will be on show at the Vintage Computer Festival August 4-5 in the Computer History Museum, Mountain View, California!! I went to this great event last year and noticed a distinct lack of Acorns. This year, together with stardotters myelin & lion, we will be representing with an exhi...

Re: New Atom owner (soon)

Until you get your MMC this might be useful . I just saw your post which prompted me to get in online... Thank you! Yes, that'll be super useful! Are you bringing your Atom to VCF? There's a slight chance that mine might arrive in time... I was planning to bring my Atom. I can start another thread ...

Re: New Atom owner (soon)

After staring at it on eBay for a couple of weeks, I finally cracked and bought the 200 euro Atom from backtoyourpast (pricey, but out of the Atoms I've seen whose owners will ship to the USA, it seemed bearable). So... I expect to be an Atom owner once it arrives in San Francisco :) Hey congratula...

The only reason to change any caps in the atom is if the video is looking a bit shonky. Or it's broken and a capacitor is the root of the problem :D I will dispel this myth that all old computers must be recapped... :D I think it's put about by people who want to make a quick buck much like roofers...

Maybe we should start an UEF archive based upon the Acorn Atom Software Archive...... With a good ATM to UEF conversion program it can be automatically done like hoglet does for the SDDOS files. Sounds interesting .... Greetings Kees I could auto-generate UEFs and audio from hoglet's Atom Software ...

Acorn Atom newbie / Playing UEFs

Hi I was kindly donated an Acorn Atom which I love. Got a few tips from these forums to get it running (never used one before...). e.g intermittent fault fixed by simply reseating the 6502 which had been working its way out of its socket for the past ~40 years! It now runs perfectly... not seen any ...

The trickiest bit was getting the timing right on UPURS...! I've done a bit of testing now, it's pretty stable at least in my set-up.
