Re: No clock signal to the Shifter

With respect to the possibility of using either 2 or 6 chip TOS on this type of board I noticed something that got my attention. On the original 520ST schematic pin 22 OE of the TOS Roms is connected to UDS and LDS and also to the cartridge port. However, on the schematic for the 1040ST the TOS Rom...

Re: Stuff and Things.

Yeah, seems like it's lost its capacitance a bit. :-) I have loads and loads of capacitors... mostly due to the one I need always being one I don't have. Either the capacitance is wrong or the voltage or the size. I know what you mean. I have a ton of caps, but none are the 10uF 250v variety, so ye...

Yep that was taken on my workbench in optimum lighting conditions. In good light, the screen is nice, but move somewhere darker and it's not great.

Neo Geo - Of the Pocket variety

I've always liked the look of the Neo Geo Pocket Colour, and being a handheld fan I decided it was time to have one join my collection: IMG20240327132546.jpg It came in the box, which was nice and I've picked up a RetroHQ SD cart solution, which is great because I can flash multiple games and easily...

Re: Stuff and Things.

And to add to the story of the workbench magnifier light, parts came today, but it didn't fix it, so I checked the two main caps just to see what was what. Turned out the cap that I found with a loose leg, was no longer 10uF: IMG20240327132238.jpg So I've ordered some caps, but if that doesn't work,...

Re: General Stuff(tm)

Well, I couldn't get any contractors to turn up next week, they all seem to be going on holiday, so I've cancelled my trip and my leave. There's no point taking time off if I need to use it later in the year. Still, it means that I'll be around for the deliveries. That's a bit of a pain to say the ...

@Icky

Yes, I remember that one well!

Looking at Astrowars, the one I'm thinking of is very similar, but narrower. Will have to try and find a pic.

I've certainly seen 1&3 but not 2, and the posts for Megas are different again.

One final item completed before reassembling the CoCo:

However, I'll be down in Cornwall next week to deal with work on my Dad's house.
Hope that all goes smoothly for you, It's a difficult thing sorting out and selling a property at a distance.
