I test ZXMAK2 with "Byte48" emulation + BDI and this is my findings:

In manual BDI wrote that need use RANDOMIZE USR 15360 to run TR-DOS but in Byte is something different. I can run TR-DOS in 2 ways:

1. RANDOMIZE USR 15616 - working with COBMECT or without COBMECT

or

2. Selecting COBMECT from menu Tools and RANDOMIZE USR 15360 or RANDOMIZE USR 15616

Is this is normal?
