CTPAK.EXE contains all of the files necessary to run CT. Make a
backup copy of this diskette! If necessary, make a directory to hold
the CT files. Copy the files fromn the distribution disk to the CT
directory. Unpack the archive by typing CTPAK.
If in doubt, consult your manual page 6.
Errata
======
Page 15 of the manual is incorrect regarding memory usage by CT.
CT86.EXE uses EXPANDED memory, not EXTENDED memory, as the manual
says. However, CT286.EXE and CT386.EXE use EXTENDED memory and
ignore EXPANDED memory.
If your computer is a 286, 386 or 486 and has more than one meg of
memory, CT286 or CT386 are usable. However, at least 1/2 meg of
extended or XMS memory must be available to CT. Either disable the
expanded memory manager or set it up to leave some extended or XMS
memory for CT.
Most of the 386 based expanded memory managers provide either
expanded memory or extended memory on demand. These include EMM386
(comes with DOS5), QEMM386 and MAX386. CT86, CT286, CT386 should all
find what they need if one these memory managers are running.
Many 286 (AT) class machines have hardware on the motherboard
which converts extended memory into expanded memory. Usually there
are switches which must be set and an EMM driver which must be loaded
in config.sys. In that case, reconfigure the machine to extended
memory for CT286 and expanded memory for CT86. CT386 does not run on
AT class machines.
8086 (XT) class machines must run CT86 and may not run CT286 or
CT386. If your XT machine has an expanded memory board and driver,
then CT will use expanded memory allowing more QSO's.
The most common reason CT286 or CT386 won't run is that some other
program has grabbed all the extended memory before CT runs. Usually
this program is a disk cache program such as SMARTDRV or SUPERPCK, or
a disk compression program such as STACKER. Tell SUPERPCK to leave
memory for other programs by using the /R: switch. /R:512 means
"leave 512K for other programs." Tell SMARTDRV how much memory it
may use by giving SMARTDRV a size parameter. For example, if your
computer has 1.5 meg of extended memory, give SMARTDRV 1 meg by
adding the number 1024 to the SMARTDRV line in config.sys. This leaves
1/2 meg for CT.
Another user of extended memory is a ram disk. The DOS5 ram disk
(RAMDRIVE.SYS) has a size parameter, just like SMARTDRV. A typical
RAMDRIVE line is:
device=c:\dos\ramdrive.sys 1024 /e
This means "setup a ram disk using 1024K of extended memory."
Be sure to leave enough memory for CT.
