Re: Sharper by Genesis Project
@Sdw Oh I didn't see your answer. In fact I already found out how to do so (or at least something similarly) once I understood there is only one star per line: then it is very easy to be able to draw in the full 320x200 area!

Re: Sharper by Genesis Project
Any technical explanation about the parallax star field? Even running on the emulator, it is quite impressive.

Re: Help: Sharp MZ 700 short fuse with video connection
You don't need to solder a SCART. Breadboard, resistors and Dupont wires and an Amiga SCART cable and then you can test. It doesn't need to be permanent. The issue is to discover whether your RF box is the culprit.

Re: Problem with MZ80-A CRT
(Answers from https://www.facebook.com/groups/sharp8bitmz/permalink/3196131587370272) I would check around the horizontal drive for a dodgy gnd connection, a faulty resistor/capacitor filter combo or the ic itself. It looks like it may be on the linearity side This is the spec sheet for the ic and h...

Re: MZ-80a US Power Supply
Ah sorry!!!! I thought about MZ-700 so yeah you may need 5V and 12V. And I wonder whether -5V may also be needed. But anyway, there are Meanwell PSUs which can provide those different voltages.

Re: MZ-700 correct filter capacitors for PSU
Do not bridge the connections! Either you replace them with more modern caps like the ones in timh's last picture or you just remove the depleted ones but never ever ever connect them with conductive wires (that's what we would call a short circuit!).

Re: Help: Sharp MZ 700 short fuse with video connection
MZ-700 is only using 5V from the PSU and it seems you checked it. RF-box is only powered with 5V as far as I know. So the issue is about the current intensity (well that's the function of a fuse). I would say if you have a multimeter, put it in intensity mode with the highest max value and check wha...

Re: Help: Sharp MZ 700 short fuse with video connection
For my experimental MZ-700 I used an Amiga SCART cable. Dupont wires to connect the inner RGB connector to DB23 (yes I know we should add resistors to decrease the TTL voltages). Color are too vivid but at last you can test as well.
