Pictures for the curious. I may just need a new monitor:

Not sure what I can do. If I get the top aligned correctly then the bottom is off and if I get the bottom aligned then the top is off.

Somehow the color convergence on my PCjr monitor has become off. The bottom is perfect, but the top third of the screen is off. It looks like the blue is a bit lower than it should be (blue fringing on the bottom of letters) but the further up you go the convergence (and clarity) gets worse. Figurin...

Interesting. I have a spare GBS, but I don't have any of the other parts and it looks like they'd be kind of pricey to acquire. I guess I'll stick with what I have for now. Forgive my ignorance here, but why is that separate DAC board needed? The PCjr outputs CGA (or a CGA superset anyway) and the ...

I think this has been discussed before, but I'll ask again: Is it possible to use a PCjr with a VGA monitor? I thought someone was developing a solution for it (maybe as part of a new JrIDE?) but that's the last I heard of it.

You have to open up the stick anyway and connect the third terminal of each potentiometer to ground : http://nerdlypleasures.blogspot.com/2016/08/the-pc-joystick-to-tandy-1000-joystick.html Does that apply to the CoCo as well? EDIT: Ah yes, I see it does. Thanks for the tip: http://nerdlypleasures....

I'm thinking about taking one of my spare PCjr joysticks and converting it to work on my CoCo. The joysticks for both systems are exactly the same, just with different plugs. I found pinouts for each system (the CoCo uses a 6 pin DIN) but on the PCjr side I see that B3 and B4 on the BERG connector a...

Software compatibility is what I'm most concerned about. Other than Lode Runner have you seen any games that were broken?

Doh! Yes I meant 8088.
