Yet another clock...
The original series of EGA clocks seem to have been written by
Bob Griggs, with a few by others.
The driver program (xxxxx.COM) was written in Turbo Pascal and
probably uses the RIX Softworks GRAPH library. The driver loads
the clock image and superimposes the clock hands and the date
window.
The clock image itself was created using EGA Paint from the same
company. (See copyrights using DEBUG).
Some clocks are variations on the original "Rolex", while others
seem to have been colorized from a scanned image (see SABRI) or
drawn free-hand.
This clock (TREK) was drawn using the new RIX VGA Paint program.
The driver is the original, renamed and patched to load a new
screen (note that the file name is limited to 5 characters).
The Clock itself comes from "Garfy", while the Enterprise picture
was captured from EGA_TREK by Nels Anderson.
If you want to build a clock using an existing one:
You will need EGA or VGA Paint. Since I have VGA Paint, here's
how I did it.
Start with a clock screen. Translate it to VGA Paint format
using RIXLATE/R xxxxx.SCR.
Expand the image using RIXLATE/4 xxxxx.SCR.
Start VGA Paint in 640x350x16 resolution.
Set LARGE ON and XPAL SET.
Load xxxxx.SCR, edit/modify, etc. Save it as xxxxx.SCR
Compress the file using RIXLATE/3 xxxxx.SCR then translate it
to EGA format using RIXLATE/0 xxxxx.SCR.
Notes: The driver uses the palette defined in the clock picture
file. The screen file name needs to be patched in the driver
program in 2 places - one is just the name, the other name and
extension (name limited to 5 characters in both). Or, easier,
name your clock with the same name as the driver program.
Have fun!
