Hi Mark and all,
many thanks for your reply with the patch. I tested it many years ago
but much better results I got with the Caldera DOS which is free for
non-commercial use. I am not sure if it is still available from their
site but you can find it on my computer dedicated site inder downloads
There are two versions available
- the full version with networking support (disk01.144 - disk05.144]
- the light version without networking support (ldisk01.144 - ldisk03.144)
You need also mkdskzip.exe, I highly recommend to download also the
readme and makedisk.txt, also diskcopy.com. All disk* or ldisk* files
are diskette images, so you will obtain a set of 5 or 3 installation
diskettes. No patches needed and TR runs on any machine.
