COMPUTERS THAT MAY HAVE BEEN USED FOR TESTING PROGRAMS
It's my policy to try to test programs on several systems whenever possible.
Here are some of the computers which may have been used to test the program(s)
you're interested in. Whether or not these systems were actually used for
tests can be found in the document file for the program you're using (if I
wrote it) or in PROGRAMS.DOC. If you don't have PROGRAMS.DOC, you can find it
on one of my Support Disks. For instance, if you want to know the results of
testing programs on the Tandy 2000, you would want the file PROGRAMS.DOC from
the Tandy 2000 Support Disk.

THE COMPUTERS IN QUESTION
AMSTRAD PC1512 SD: This system has an 8086 CPU, a composite monochrome
monitor, and CGA which can access 16 shades of gray (or color with a color
monitor) with a resolution of up to 640 X 200. The system originally came
with 512K RAM, which I've upgraded to 640K. It came with a single 5.25", 360K
drive. A second internal drive of the same type was later added, and I've
installed a 49Mb hard disk card. Operating system is MS-DOS 3.20. This line
has been discontinued. This utility had no problems running on the Amstrad.
PACKARD BELL PACK-MATE: This system has an 80286 CPU and a color VGA monitor,
which generates 640 X 480 pixels resolution. Drives are one 40Mb internal
hard disk, one 5.25", 1.2Mb drive, and one 3.5", 1.44 Mb drive. Operating
system is MS-DOS 3.30. This utility had no problems running on the Packard
Bell.
TANDY 2000: The Tandy Model 2000 uses an 80186 central processing unit, and
can accept both monochrome and color monitors. The unit I'm testing has a
color monitor with CGA graphics; the color guns have been somehow damaged, and
the colors are not quite correct. However, the color is sufficient for most
purposes, and the unit is still in minimal use. This unit has a detached
keyboard, which is neither identical nor fully compatible with the IBM
keyboards. It has two 720K, 5.25" floppy drives, but drive b: is not
currently operational. There is also an external 10Mb hard drive installed.
This system is using MS-DOS 2.11.02; the operating system has been tested on
IBM compatibles, and will not boot. As far as I know, it will only operate on
the 2000. It includes GW-BASIC 2.02, Tandy release 2.02.01. Many of the
utilities included with the operating system will function on IBM compatibles.
On my Amstrad, however, they will only function when an IBM-compatible version
of MS-DOS 2.11 is booted.
