Game & Watch Box

Slightly odd question. But as I see a few other Nintendo enthusiasts on here, you may be able to help me here. Having recently found a Donkey Kong G&W in decent condition for an absolute bargain, (with the battery door! HA) I decided to also get a repro box for it. However, The dimensions were not l...

Re: Screen Flicker

I suspect this is a glitch in the sync line causing the converter to reinitialise and maybe what was causing the problem with the TV which took longer to recover so the flicker was more noticeable. Ideas please on what could cause such a glitch and how I could fix it.. This is similar to my Electro...

Re: Screen Flicker

Since I had a similar problem with my Elk, is it a straight on-off flicker? Or does it shudder up/down and disappear?

Obscure little handheld (Melody Alarm)

Right... Since lockdown has given me free time, I found a little handheld game&watch type console in a cupboard and thought i'd restore it to working condition (since I collect such things) However, while it does "work", i'm missing the little battery door on the back, so the connection is intermitt...

Re: Model B - passible faulty cassette interface?

If you've tried that many cables and drives, there's a good chance that something isn't working. (Captain obvious strikes again) Not an expert on beebs, more an electron bloke. But it's unlikely the port itself is dead. They're usually pretty well made. If it's getting no signal or not acknowledging...

Unfortunately a butchered IC socket would be way to big.

Well, if you cut one off at the plastic dividers between the pins, they look about the same.
Ruler is a bit out of focus but there's not much I can do 'bout that.

Re: Micro Jumpers for Seagate HDDs

I can't really get a sense of scale from the images, but it at least *looks* quite similar to a double-wipe IC socket's contacts. maybe cut part of one off, solder a wire between 2 legs at the right distance and turn it upside down?

Re: Atari 2600 - doesn’t like switching PSUs

I can only assume therefore that there may be something wrong with the first one? As I say. I'm not the go-to guy for Atari, but like with some Commodore 64's, different revision motherboards have (a) different components, affecting the video output. And (b) varying degrees of sharpness/contrast pr...

Now. I'm no expert on Atari, but I know my way round them a fair bit, and being a collector of vintage consoles, I need to know how to fix them. It seems to have seriously minimised interference but, and this is possibly just my imagination, slightly reduced picture quality with a little more blur. ...

Re: Another Elk lives

Another alternative power supply that's quite easy to get hold of is a Hornby C912 controller brick. I have one as a spare and it works slightly better then the original brick. 19-20v AC last time I measured.

Re: Power supply

I've found that a Hornby Railways C912 controller supply works brilliantly. 18-19v AC. actually looks quite similar to an Elk brick, except it's jet black.


When you're looking for an RGB lead (on ebay I assume) try having a poke around. there's usually a few about.

Re: New Atom owner

Probably the more obvious option, but a good ones nonetheless. I would try reflowing the solder for the composite port and checking the traces going to it I'd also try running temporary wires from the Co' port to another phono port (the RF being the best option) to see if the socket is duff.

thanks for the idea, I have tried it and while it didn't *completely* fix the NTSC/PAL issue, it DID fix the slightly blurry pixels that you get from the LK4 mod. Thanks a bunch!

The only variable capacitor on the board looks to be over on the left near the modulator on the issue 6? Disk shaped thing with a little screw in the top?
