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...

Re: 800xl power supply - how to open?

Ok I'll answer my own question in case it helps someone else. The PSU is potted (encased in resin), so the base of the casing has posts on it that are embedded in the resin. I used a chisel to break those off from the inside and then by soaking the main PSU in boiling water several times and applyin...

800xl power supply - how to open?

Got a power supply for my 800xl. It's an original Atari one but seems to put out 0v on all pins. I want to open the case up but there are no visible screws. I wondered if anyone had some insight into how to open it with minimal damage? I suspect I'll replace the insides with a usb charger, but would...

Re: Gotek as an external floppy drive

I dropped a Gotek into a Datel external drive enclosure and had noproblems. That particular enclosure has no internal electronics other than a power regulator and the 14 pin DIN plug goes straight to a 34 pin floppy connector. Which reminds me I need to finish off my wiring diagram and post it on h...

Gotek as an external floppy drive

Currently my gotek is replacing the internal floppy drive on my stfm because my machine had the original drive missing when I bought it. I recently acquired an original floppy drive so want to put that back in the machine and make the gotek external. Questions I have: 1. Can I make the gotek into an...

Tidying up a 3d printed case

I've just bought a SDrive Max for my 800xl. The case is an XL style case that's been 3d printed. It's fine from a distance but a bit rough and could really do with smoothing some rough edges and maybe even filling and painting to remove some imperfections. Before I start doing that, I just wanted to...
