Sharp MZ

very nice demo ! Bravo.

Cheating at the BEYOND game is possible: When opening a game board, press all the B, E, Y, O N and D keys and the screen is erased to reveal the message "PROGRAM AMMENDMENT". There he asks us "SCREEN NO". Apparently only the numbers 0 to 4 give us access to a table. Then "DI...

I'm an idiot: It was enough to look at the datasheet of the 74ls221 to actually see the wiring of the H which is indeed at 5V!
Sorry for the inconvenience.

Awesome ! thank you hlide.
There are the details that I wanted to validate this circuit. So if the terminal is connected to Vcc it is therefore that H means HIGH.

I actually plan to build a replica, but I have a problem on the diagram in the manual: It says a clock H for controlling circuits 74157 and 74221 but which is not connected to anything, so I suppose that there must be an astable or monostable circuit which is not present in the diagram. It is for th...

Hi,
I wanted to order the Beyond game from the SHARPWORKS site, but there is only paypal for the payment, so I gave up, not having and not wanting to use paypal.
Can't order a digital version (.mzf for example) by credit card or other means such as paper mail?

Good morning, sir,

I'm looking for a MZ-1E14 card, not too expensive, in order to use it with an old MZ-1F11 reader, even if it's out of order.

Thank you.

I have three working MZ-700s, and currently only the MONITOR ROM is reproducing the problem perfectly on all three. I haven't tried to remove the processor but it must be a possible case. I think it's normal after a little analysis, for what it's worth: The CPU isn't running any program because the ...

I made some tests, and those that reproduce a blow on the problem, it's a defect in the MONITOR ROM, i.e. when I remove the ROM and I restart the machine, it locks in exactly the same way on the random display of characters and colors on the screen without doing anything. I'm investigating a problem...
