Re: MZ-80B project (Floppy Disk I/O Card cloning!)

SFD800 - 1.png 115.5mm x 95mm x (edge connector facing towards you, 34mm x 57mm x 24mm). You can still buy all the ICs, the 74HCT are an ideal replacement, the WD-1773 can be found on ebay, ie. https://www.ebay.co.uk/itm/362668881645?hash=item5470bff6ed:g:06YAAOSwnDRcXYEn - be wary of IC's from Chi...

Re: MZ-80b FI/O to HxC Cable

Not tried the Gotek, just Lotharek's HxC (SD CB - HXC Rev C BLACK CASE) and a dual Cumana 5.25 disk pack. The HxC is an older model and it works with the MZ-80A/MZ-800/MZ-80B and BBC Model B but not with my Sharp X1 which uses the same 37pin external D-SUB!!!

Re: MZ-80B software

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...

Re: MZ-80b FI/O to HxC Cable

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...

Re: MZ-80b FI/O to HxC Cable

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...

Re: MZ-80B software

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...

Re: MZ-80A RFS Board / MZ-700 tranzputer Board

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...

MZ-80A RFS Board / MZ-700 tranzputer Board

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...

MZ-700 Upgrade - tranZPUter SW-700

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 ...

Re: Mz80-A no cursor

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...
