Re: Atari 2600 - doesn’t like switching PSUs

I managed to get the composite mod board inside the metal box by changing where the wires run and not having to drill which is a bonus! It seems to have seriously minimised interference but, and this is possibly just my imagination, slightly reduced picture quality with a little more blur. Maybe the...

Re: Atari 2600 - doesn’t like switching PSUs

Thanks Mark and John. Is it a 1000uF electrolytic cap in the ZX81 PSU? It certainly sounds an easier way forward than the other route! Most of the PCB is in a metal box but some of the circuitry is outside it. I will pop the case off and take a photo. Part of the composite mod is outside the box. I ...

Re: Atari 2600 - doesn’t like switching PSUs

I have tried 3 different switched PSUs, all three outputting 9V.

One from here https://www.thefuturewas8bit.com/shop/s ... irpsu.html

One from here https://www.oldskoolconsoles.com/produc ... wer-supply

And one that came with the Atari. It looks pretty cheap and nasty.

Atari 2600 - doesn’t like switching PSUs

Hi all I have an Atari 2600 which I recently got to a usable state. When I got it the picture was awful and had silly amounts of interference on the screen. It was often worse than this: C3A7B945-B3C8-4EDF-8BBA-383C89D05CA9.jpeg I have changed the main power cap (a 2200uF beast), the electrolytic ca...

I am a backer of the Atari VCS console though, but don't know when that's likely to arrive. Whats that one? It's a reimagined Atari VCS (2600) games console, made by Atari but isn't retro like the Spectrum Next. It's all modern up to date architecture inside. https://atarivcs.com/ Interesting looki...

Re: Acorn Art Thread

I wonder whether to post art up that could be controversial and with dark humour. Satire and sarcasm is not always palatable...but then art has always challenged the world around us good or bad....for better or worse. Maybe create another ‘dark humour’ thread? People can then always not look at it.

Re: FOR SALE: WH SMITH CPD8300 Data cassette recorder

I have one of these as my main tape player for retro computers - its really good.

There is a Spectrum setting on mine on the back - it does indeed make loading much easier on the Spectrum. I wonder what it actually does?

Re: BCPL Keystrip

Yes - the keystrip is for ED the text editor. You can use any text editor providing it produces an appropriate text file.

Does anyone have a copy of the Calculations Package manual? I am trying to put the all the BCPL stuff in one place.

Re: Electron loading volume

Thanks all. This isn’t a problem I was just curious! I actually RTFM’d and it says to start at 2/3 maximum volume and if you don’t get anything turn the volume up! To be fair I have no idea if changing the volume setting has any effect on the recording level - I only tried it a couple of times just ...

I have tested saving to tape and then loading again.

It works if I save at volume level 7 and then play back at volume 2 or so.

This is my tape player - set at 3 which loaded 8 different Elk tapes last night (some were set at closer to 2 to load).

Electron loading volume

An Elk noob question (probably not the last) - what is a typical loading volume for the Elk? It says in the manual to load at 2/3rds of maximum volume. I tried this and got nowhere. The Superiorsoft games that came with it load at around 2.5 to 3 out of 10, rather than 6 or 7 (where my beeb, Spectru...
