Sharp MZ

tbh I'm not sure, never got that far, I always assumed I'd reference original.sharpmz.org when needed, ie. Download->Common Utilities->File Transfer. There is a tool there which converts MZF/M12 (no idea why so many formats) to physical tape. Probably best to scan this forum or wait for a more knowl...

I use an external USB to 5V converter. Unless I hack the hardware, 5V isnt available from the MZ-80A. I'm also changing the HxC between machines so it keeps it simple. When I first got the MZ80B and HxC 2 years back I was able to boot the SA-6510 from the HxC no problem. The MZ80B has an SFD-800 car...

I've done it for my MZ-80A using the schematics here https://original.sharpmz.org/mz-80a/download/80afi_diag.pdf and connect it with a Lotharek HxC Emulator. From memory I didnt make any special wiring just straight forward 34pin IDC connector to the 37pin plug wiring signal to signal. FD - 1.png FD...

I sent you a PM over 2 weeks ago but for some reason never left my outbox, so copying it below: If you need the MZ-80B IPL source, it is stored here https://github.com/pdsmart/tranZPUter/blob/v2.2-tranZPUter-SW-HW_700_v1.3/software/asm/MZ80B_IPL.asm ---------------- All the files listed below are on...

Thank-you, will put one aside. The video card has a bug on the external display output I think arising from the Sharp MZ Gate Arrays which I only found out whilst readying a board for a guy and made some final tests. The issue is in the external Vertical Sync and Horizontal Sync separation, the sepa...

I've got to a point on my projects where I feel other enthusiasts may be able to make use of them, namely: MZ-80A Rom Filing System Upgrade board - Adds ROM / RAM storage and SD Card along with an upgraded monitor which runs alongside the original SA-1510 Monitor. I've also updated BASIC SA-1510 and...

Just thought I would share my most recent board with the forum as I slowly piece together the documentation which can be found at https://eaw.app/sharpmz-700-upgrades-tranzputer-sw/ This is an amalgamation of my MZ-80A developments for the Sharp MZ-700 providing it with a much needed boost in terms ...

Found the reason today by accident, basically replace your 8253 Timer IC (IC 47). I was transferring developments from my MZ700 board to my MZ80A board and inadvertently blocked $E000 - $E7FF which manifested the same problem you have, ie. no cursor, just the monitor signon text. I then decided to n...

Just had time to double check and I was wrong in terms of the cable wiring when I removed /HSYNC+/VSYNC+CSYNC and replaced it with just CSYNC working. It was my new board that works with just CSYNC but on the MZ700, even though it is not electrically sound, shorting /HSYNC + /VSYNC + CSYNC together ...

I need to double check what I said above as I cant remember whether I tested the modified cable on the original MZ700 hardware or my new board (which has selectable +CSYNC and /CSYNC). CSYNC on SCART should be positive whereas the MZ700 is negative. Although not electrically correct it may be workin...
