Re: Tri-Data Cartrifile parts/interfaces/tapes?

Hello Jim. I read on the forum that you have a Tri-Data Cartrifile cartridge. I'm looking for them for my cassette collection, but they're nowhere. I am a collector of tapes, cassettes and disks ... I have a question. Can you sell me one cartridge? Best regards Greg.

So, the bad news is no way found so far to make bootable floppies. Maybe not bad news as it gives me another fun project to work on. Further good news, however, is that I have revived my M3SE, MISE and 2 FreHD's so I now have hard disks for pretty much all my old systems. Just have to build

I don't know about TRS-DOS but a lot of early floppy disk format programs had an option to make the formatted disk bootable or not. This would copy the bootloader to the appropriate location on the floppy, copy the OS to the floppy and update any necessary pointers to the OS on the floppy.
