Huh? Where are you trying to load the monitor program in .mzf file? At which address? The monitor in ROM cannot load a program at a load address lesser than $1200: it is forbidden by the monitor.

EDIT: Ah yes! the 1Z-013B is the BASIC, nevermind !

Re: MZ-SD2CMT - correct wiring?

The source is working. The README.md is not updated. You need pin #3 because I use it to emit a one-shot pulse (PWM).

Re: [MZ-SD²CMT / MZ-CH376] Ideas for fast loader/saver program without the need of GUI on the SD device

Cool! Is the project source available? I'm totally interested in your browser to make a version for MZ-SD²CMT without GUI with all the credits to you for this part. For the entry order issue, there are some PC softwares which can reorder physically the entries in the alphabetical order. I don't know...

It seems that the price is not to high, and no changes needed to be done to the computer.

Not a good idea, composite is very ugly on a HDMI.

Beware! $F000-$FFFF are used for ROM like floppy disk drives.
I know this ,but as I am not going to use a FD I think this sould be fine.
it seems you are lucky:

Code: Select all

	IPL.ROM		$0000-$0FFF
	FDIF.ROM	$F000-$F3FF (MZ-80FIO Boot ROM)

RESET: you're lucky! :) I didn't check it and wasn't sure because in numerous schematics or tables about SHARP MZ you can read some signals named without negative marks while they are active negatively. So always double check as you did ;).

Are those errors just regarding declaration order? Adding some forward declarations should fix them.

Re: [MZ-80 K] Serial interface through I/O ports $F8-$FF

Revised my last post as I made a big mistake in the way to handle /CSEx. In the end, using /CSE should be enough.
