Summary MESS-specific 06484: rm380z: The COS 4.0 does not support cassette !
Description The 380Z and 480Z Firmware Reference Manual ( ) on page 1.5:

"Firmware commands:
L ... Load program from cassette (All versions except COS 4.0 and 4.2)"

So as this command does not exist on COS 4.0 there is no need for cassette!

Steps To Reproduce Start the driver and type in the monitor command L.

It does not work as a such command not exist on the COS 4.0 system ! (Btw. It works on COS 3.4 system!)

So the cassette feature should be removed from the "rm380z" driver and left only in "rm380z34d" and "rm380z34e" drivers that support cassette.

Note that driver "rm380z34d" does not support the disk drive ! (commands B or X does not work but only command L)

So according to that the disk support should be removed from the "rm380z34d" driver !

rm380z ... supports the disk drive only !
rm380z34d ... supports the cassette only !
rm380z34e ... supports both, the disk drive and the cassette !

See in the same (above mentioned) manual on page 6.2 the Table 6.2 380Z interface I/O ports !

One more issue with "rm380z" driver:

On the video below at 1:34, after typing the letter B is written "Disc not ready", while in the emu is written " isc not ready" !? (Letter D is missing!)

And this is not the only problem with this driver! (IMHO, the driver needs complete overhaul)
