Re: 800XL memory upgrade options in UK

Thanks @tzok

Is the expansion that this person is selling the same thing? If so, looks like he/she already has some built up for not much money (23 Euros)

Will try contacting and seeing if they still make them

Re: 800XL memory upgrade options in UK

Thanks rubber_jonnie - certainly worth considering then. I'm always a little wary about upgrade cards that do a lot of extra things for very old machines - before you know it, the original hardware is not really needed at all and it starts to defeat the object (for me at least). I'll definitely give...

800XL memory upgrade options in UK

Now the 800xl is up and running and I've been able to play a few of the games I remember from my childhood, I'm tempted to look at upgrading to allow for running the 128k games I never got to try back then. There seem to be a few options out there, from Rambo boards to upgrade to 256k to full on 1me...

Re: 800xl video

I've got a pretty good picture now using svideo and a number of mods from various online resources, so I will list those that I've found made a difference here once I'm done. As tzok has said, so far very little has been needed to get quite a nice picture. There is one area of improvement still I'd ...

Re: 800xl video

Hi all So I've done some of the simpler svideo mods and undoubtedly have a sharper picture, however I still had zigzag interference on the blue background of the screen. I played around and have finally (I think) found the solution: Using an svideo cable, if I touch an earth wire to the metal outer ...

Re: 800xl video

Thanks rubber_jonnie . So far all I've done is feed a cleaner 5v supply to C51 and remove L5. Made a tiny difference, but not much I'll do a recap anyway, but wondered if noisy old electrolytics could be making things worse? If you can find the mods you've had success with, that would be really useful

Re: 800xl video

Thanks rubber_jonnie yeah I did look at those too. They just seem a bit over the top for what I'm looking for I think. Also adding complexity is the shipping costs involved - especially from the US. Think I'm either going to do the DIY mods for svideo and see how things look from there, or see what ...

Re: 800xl video

I've been looking at the UAV board and appear to have found someone supplying them in the UK:

https://shop.ctrl-alt-rees.com/products ... 7800-8-bit

Anybody had experience of ordering from them as I'm not familiar with them?

800xl video

Trying to work out the best way of getting a decent video signal from my 800xl. So far I've tried: 1. RF output - this has vertical lines on the background and a kind of 'zigzag' pattern along the left and right hand edges where the blue screen meets the black border. 2. Composite out via the din co...
