hello all!
I just managed to get another mcs 2000 sl back to life!
it is a machine in very good condition with german software.
it was build in 1992 and was "upgraded" until 1998 with diesel smoke control and other "goodies".
dumping the copy-protected non-IBM-floppies with the HxC software was (thanks to this forum and thread!!) quite easy.
I had a stock of about 15 different discs 7, of them with bad sectors.

but I managed to dump the V552 system disc and the v552 AU-2 disc to .hfe files.
this ist a matching late twin-disc version enabling the MCS2000It to test 3-12cyl. engines with free programs or test the lambda control system for german exhaust emission control test.
HxC emulator was set to "Emu Shugart", sound to maximum, lights and device "on"....the scrolling filename ist difficult to read, but as there are only two files this is OK.
