Sharp MZ

Unfortunately in Japanese:

BASIC: https://archive.org/details/MZ80SERIESBASIC.

ASSEMBLER/TEXT EDITOR/RELOCATABLE LOADER/SYMBOLIC DEBUGGER: https://archive.org/details/MZ80SERIESSYSTEMPROGRAM. I have those tapes in a box.

Open it and take shots and post them here if you cannot determine what the culprit is:

1) the motherboard.
2) the inners of PSU.

I think I have the Language Machine manual somewhere but I cannot figure where. And it doesn't seem to be on the internet.

In which programming langage is "Evil Star"?

"Evil Star"? I recall having read something about it as a text game on MZ. Something which contains some Star Wars similarities.

My first MZ-80 K did make a bang then smoke. But it didn't take fire. The MZ-700 I bought under one year ago has the "famous" X2 capacity exploded (it was already this way before I bought it). Whenever I powered it, I found it smelled too much so I decided to have a look at it. And I made ...

FR: Ok, j'ai profité de ce weekend - non sans quelques difficultés - pour avancer sur mon projet. J'ai commençé à apporter une modification pour être en mesure de lire un MZF et de le transcrire en SHARP PWM. C'est un travail en cours. Je voulais garder la même façon de procéder que pour lire le fic...

I would love to have both MZ-80A and B but I guess the prices won't be cheap. And damn I start lacking places to put my retro-computers :/.

I am beginning to wonder if it might be the monitor ROM (EPROM?) at fault. It looks like VRAM is fine as the display is perfect. I just cannot understand what else might stop the monitor program completing its loading as I assume the memory test is in ROM? ROM needs a small RAM space (0x1000-0x11FF...

For the program to be loaded, I suppose you got it recorded on a tape. If not and you have an MZ-700 with a working tape recorder, there is a way: enter the bytes with M command and save them with S command in a tape. Then you should be able to play it on MZ-80 K. There is a small complication: if y...

I made a program RAMTEST to determine which row and which chip has an issue: the program is loaded into VRAM (so you'll see some weird characters at first lines) and will check some patterns (D0 chip: 01 - D1 chip: 02 - D2 chip: 04 - D3 chip: 08 - D4 chip: 10 - D5 chip: 20 - D6 chip: 40 - D7 chip: 8...
