Re: Color GAL5, color board for MZ80KC/1200

Front page, well used and dated, I learnt digital electronics on this machine and the manual was a constant source of info.

Re: Color GAL5, color board for MZ80KC/1200

My apologies, I didn't see the notification and was preoccupied with my projects! I'll attach the photos but the machine was definitely bought in the UK by my brother in 1982 sometime around July->Sep (I know this as we emigrated back to the UK and my brother came back 3 months before I did). I no l...

Re: Color GAL5, color board for MZ80KC/1200

I had a more closer look at my manual, the MZ80A was purchased circa mid 1982 and it has a similar number of pages to the pdf on original.sharpmz.org, the latter is either lacking pages or skips the blanks in its pdf numbering. I've attached the differences that I could see without page by page comp...

Re: Color GAL5, color board for MZ80KC/1200

Just had a quick check, the manual on the original.sharpmz.org is different to my original manual. Mine is dated September 1981 and has a lot more pages, it also has the serial number 080311-250981.

Re: Color GAL5, color board for MZ80KC/1200

Hi, When I made the first version of the board I didn't have as much info as I do now, the designs are more an evolution than ground up design so all the information your providing and what Im digging up should hopefully result in a better v2 design. In all honesty, I didn't fully consider compatibi...

Re: Sharp MZ Hardware Emulator on MiSTer

Hi Hilde, I didn't realise the HDMI had changed to a free custom version, I will investigate this and add it into the emulator. I stopped real development on the emulator when Sorgelig didn't approve of my custom menu's taking up too much space in the Main binary for an 8bit machine and I then went ...

Re: Color GAL5, color board for MZ80KC/1200

Hi Hilde, I will be making updates to the board soon, mainly as I made a big mistake in the PCB design, I got the footprints of the 2 gate arrays the wrong way round, not sure how but it meant a lot of fine soldering to fix. The MZ-80A mapping of the colour attribute RAM is different (page 167 of th...
