Sensoray 512 DOS - Manual (Page 11)

C:\X12DOS\X12TSR -2 –S1 –C1 –AF00 –AC00
Loads X12TSR.EXE for two 512s and sets the video input to SVideo input 1 and the base address to F00
(hex) for the first 512, and composite video input 1 and the base address to C00 (hex) for the second.
NOTE: When shipped, the parameters files are setup for NTSC and video will not pass through correctly
if a PAL source is connected. To fix the problem run VSETUP.EXE with the –PAL switch and reload the
TSR. The 512 will now remain in PAL mode until VSETUP.EXE is run again with the –NTSC switch.
Before you can reload the TSR you must either reboot your machine or type X12TSR –RM to unload the
TSR from system memory.
