SPECTRUM Robert L. Hummel
Command 1987/No. 12 (Lab Notes)


Purpose: Provides existing software with a selectable
16-color palette (from among 64 displayable
colors) when used with an Enhanced Graphics
Adapter and an Enhanced Graphics (or similar)

Format: [d:][path]SPECTRUM

or (see second format, below)

[d:][path]SPECTRUM xx xx xx xx xx xx xx xx xx
xx xx xx xx xx xx xx

Remarks: SPECTRUM is a memory-resident utility that is
normally loaded as part of your AUTOEXEC.BAT
file. Once loaded, pressing Ctrl-` (the Ctrl
key and the grave [reverse] accent key) pops
up a display of 16 color boxes, each of which
may be set, on-screen, to any of the 64
displayable values. The cursor pad keys are
then used, as described in the display, to
select any of the boxes and their 2-digit
color codes. Pressing the End key saves the
current color selections and returns you to
your application. Home resets the color
palette to its default values, and Esc aborts
any changes made, restoring your previous
color settings.

For loading or changing the SPECTRUM palette
without using the pop-up window (e.g., as
part of a batch file), the second Format
above may be used. The values for x may
range from 0 through 7 and must be entered in
pairs ON A SINGLE LINE (not on two lines, as
shown). A single space must separate each of
the 16 pairs of digits, and a single space
must also separate the number-pairs from the
command name. Use the pop-up window to
determine the proper number-pairs initially.

1. Software programs that write directly to
the EGA registers will override the
SPECTRUM color selections. The SPECTRUM
colors may be restored, if lost, by
activating the display window (Ctrl-`)
and then pressing the Esc key.

2. EGACOSET.COM, is an
alternative program to SPECTRUM.COM.

  1. Very nice! Thank you for this wonderful archive. I wonder why I found it only now. Long live the BBS file archives!

  2. This is so awesome! 😀 I’d be cool if you could download an entire archive of this at once, though.

  3. But one thing that puzzles me is the “mtswslnkmcjklsdlsbdmMICROSOFT” string. There is an article about it here. It is definitely worth a read:
