Good morning
I use MAME 0.209 with the UBUNTU 18.04 to emulate the Z80NE machine.

I can't operate the version of the machine with the floppy interface LX390, in particular I can't start the floppy with the NEDOS.

Does anyone use this machine?
Thank you

Z80NE support was submitted 10 years ago by someone who is not a team member so we don't know too much about it.

That said, it looks like you want to:

mame64 z80netf -flop1 /where/is/your/disk.dmk

When the screen comes up, press Print Scrn to enable MAME keys, then Tab to open the menu. Choose "Machine Configuration" and change the "Boot EPROM" to "EP1390 Boot Loader for NE-DOS 1.0/1.5" or "EP2390 Boot Loader for NE-DOS G.1" depending on your NE-DOS version. Press Tab to close the menu, and then press F3 to reset. You should then get a screen asking to press Space to boot NE-DOS.

HI tank's for answer.
I do this command "mame z80netf -flop1 /where/is/your/disk.dmk" and "EP1390 Boot....." machine configuration.

I press "Space" but the machine doesn't react. It would seem that the space button or the floppy is not read.

Are there any particular settings to be made beyond those indicated?

I found the disk image and tried it myself and indeed it doesn't react to pressing Space. There may be a regression in the driver.

Do you think anyone can do something about the drive?
Is it worth trying with the version under Windows?

The Windows version of MAME will behave identically. If you're familiar with the internals of this machine and can read/write C++ you might be able to figure out what's going on in the driver yourself, otherwise you'll just need to wait for a developer to take a look.

Regression seems to have occurred in between MAME 0.193 and MAME 0.196.

Debugger traces suggest this might have occurred with changes to the KR2376 keyboard encoder device (a91c079afb1db0e9644436624702cee84e97fa7f).

Indeed it was related to that commit. The keyboard inputs hadn't been actually hooked up to the device for z80netf.

Unfortunately I have no skills to do these checks.

The developers of this machine are still in the group?

In fact even in the version with the basic loaded the keyboard does not work completely: for example the Backclear button does not work.

If I use version 0193 does the machine work?

How can I attach the keyboard inputs to the Z80NETF device?

The keyboard was corrected in git (I don't think it made it for 0.210). If there are still individual keys with problems, please file a bug at mametesters.org.
