Sharp MZ

I may be interested in the QD drive and its interface board.

Oh I forgot to say: it looks like H is connected to VCC, i.e, 5V.

I annotated the rear PCB as much as possible because I don't want to break anything out of forcing dislodging it:

While I have one, I wasn't confortable to dismantle it as I may break it by trying to dislodge the PCB (one main and two smaller for switches).

I fear I cannot tell more about. The usage I have for Unicard is a little limited (no RTC, no ethernet - everything through SD). What you want looks like a tape queue where you queue the MZF files in the wanted order (that's a thing we can find in MiSTer SharpMZ of P. Smart). I'm not sure whether Un...

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.
