Sharp MZ

Hi all,

In case you missed it elsewhere, I have scanned in a full copy of the MZ-80A Owner's Manual and made sure I used OCR as well. You can find it here:

https://mz-80a.com/books/

This replaces the previous PDF which had a number of pages missing.

Interesting! Presumably just for the MZ-700 / 800 ?

I always assumed MZT was for tape files and MZF for floppy images but I've always just used MZF anyway

Wow, that's pretty extensive! I will spend some time reading. Thanks!

Also MZ-80K2 and K2E. Would love to know the differences.

Thanks, that's a good diagram! It'd be nice to expand that into the other MZs. Because, for instance, I don't really understand what the MZ-2200 is, and some of the others.

Although that isn't the interrupt part but shows how to swap between pages of VRAM. Is this actually not available on the MZ-700 ?!

How do you swap VRAM pages?

"Double Buffer Horizontal Split"

Ahh... That's a bit diappointing, I've always believed that the 700 had hardware scrolling. Not that much use in the extra VRAM then. There is use in the extra VRAM. I use the second page in conjunction with an interrupt to swap between VRAM pages on my 80A to create new (non Sharp) graphic charact...

Thanks Hlide. Yes, I could have been clearer. Of course, I nearly always end up using the two pages of V-RAM on my 80A But indeed you could get 1048 bytes from the unused 2nd page if that's preferable.
