[Trlog] Re: [PVRC] TR-Log on fast computer.

[Martin Kratoska]

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

http://marcom.euweb.cz/drdos.html

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.

73,
Martin, OK1RR
