Sharp MZ

So if there is no prompt "*" on the next line of "** MONITOR SA-1510 **", the issue won't be the 556/8255. Correct?

That's just an idea I had because modern TVs don't like at all when a pixel is alternating colors. So I wanted to avoid the color gradiant through flashing done to the screen because the bigger the difference of luminosity between two alternate colors is, the uglier the pixel flashes. So I thought t...

Well, that thing was for the MZ-700 text outpout. The point is the palette (in discreet viewpoint) can be a ROM getting the current internal RGB output (A/B - 3 bits) and the previous internal RGB output (B/A - 3 bits) as input and outputs C color (6 bits, the pair of which are merged into an analog...

video hardware in the FPGA along with 640x200 pixel graphics 8 colour (due to lack of RAM inside the FPGA, otherwise would be xxx colours). Hi psmart! may I suggest a thing? when I was on BrickBuster game, I was trying to get more than 8 colors without hardware add-ons. The idea was chang ing the c...

Oh Keirf... I wouldn't judge here... Keirf isn't Jeff and Keirf has the habit to copy Jeff's new features and sources. You probably need to stick with Jeff's solution as it was validated with his firmware.

Good observation. This one is lurking outside the page. What would be the purpose? Hoping to be scooted in the top of Google pages with "fisting" key? well that's not the best place... I really doubt there is a big activity on SHARP MZ pages...

Sorry I mistakely rewrote ysblokje post but I was able to reinstitate his post (pfewwww!) through the browser history (thanks to its cache, I huess). but boy is that graphics hardware funky to me. I started my .asm coding on x86 with good old VGA where a pixel is a byte like the gods intended! You m...

Did you follow the guidelines for how to connect Gotek pins to a QD-drive interface? that's quite different from the Gotek pins to connect a FD-drive interface. https://torlus.com/floppy/forum/viewtop ... 010#p21010

I took a MeanWheel. I don't recall which one. Look at the bottom of the MZ-800 to see how many W it delivers. Take the MeanWheel with a power a little higher that the demanded one. For instance, if you look for 20W, I would consider this one : https://fr.farnell.com/mean-well/rs-25-5/power-supply-ac...

I don't recall there were MZ-800/NTSC so the chance to find a 110V version of MZ-800 PSU are close to zero. But you can replace the PSU block with a generic PSU which can deliver 5V as I did for a MZ-1500.
