Re: Some Apple II's needing TLC at Hampshire ABUG

Found the following page which talks about the PSUs: http://www.appleii-box.de/D04_allabotpowersupplies.htm Can't find anything specific about the PSU in the original Apple II, with regards to the capacitors. Have posted to a couple of Apple II forums, so hopefully will find the answers.

Re: Some Apple II's needing TLC at Hampshire ABUG

The Power supplies will be screwed into the case, would it be possible to remove them from the cases and check if they are screwed or riveted together? If they are screwed would it be possible to open the PSU up and take a good quality picture of the insides of the PSUs, that way we can hopefully i...

Some Apple II's needing TLC at Hampshire ABUG

Hi All, I've already mentioned this briefly in the ABUG thread, but thought this would be a better place for the discussion. One of my best friends passed away just over a year ago from a brain tumour. We'd worked together at Sun for many years, and I regularly stayed with him and his family when I ...

Re: Master level shifter for PiTube Direct won't fit with VideoNuLA

It's getting a bit tight in my case already.

We've got the VideoNuLA, PiTube Direct, Econet, MultiOS and Internal DC.
Next project is to build a BeebSID to go along with my BeebOPL and see if I can fit both of them in the case. :D

Re: Master level shifter for PiTube Direct won't fit with VideoNuLA

Got it all to fit. Found some 12mm pins on eBay and they are perfect:

The PiTube just clears the VideoNuLA and leaves plenty of space above for the internal DC.

Just in case it helps, this is what the game actually looks like:
