Re: Help new QD owner

Thanks! I now have a working BASIC disk :) I'm sure these QD commands are documented somewhere, but I could not find anything.

Help new QD owner

My new MZ 800 comes with a QD and some disks. I know nothing about QD, and I found that most of the disks I got (including the original BASIC disk) are unreadable. How do I create a working BASIC disk? Somehow I must transfer the 800 QD BASIC to a real quickdisk, but how?

I'm now the proud owner of an MZ-821 :) Extremely well packed and arrived safely and in working condition.

Re: WTB: MZ-800

I'm afraid I've already sold the QD+interface to goev.

Re: Joy Stick MZ-1X03

You are right, I have not noticed this before. The rate can probably be derived by looking at the assembler example in the manual, but yes, looking at the actual circuit would be easier :) Btw another approach would be to use a small microcontroller instead of the original circuit. The protocol appe...

Re: Joy Stick MZ-1X03

I'm afraid I don't have any pictures of the interiors. Are you planning to build a replica? You probably know this already, but the schematics is available in the manual.

Re: WTB: MZ-800

Looks like stock 821's go for around 150 euros on eBay. I have no idea what the QD is worth though. To me - not very much I'm afraid. Interesting technology but not very practical today. Where are you located?

Re: 700/800 - are custom taperoutines common?

That's something I wanted to do with my existing project (mz-sd²cmt) but the AVR is not fast enough to handle memory bus unless you plan to use /halt, /busreq/ack or /wait to take the full control when needed. True, a faster microcontroller is needed. Something ARM-based, like the Teensy series, wo...
