Here is a glass cockpit system I did around 1989 and 1990 when
GPS first became widely available. I obtained the entire FAA data
base on all the airports in the US. It took me a couple of months.

It was done on a Dos computer with Quick BASIC.

It could be ported to the Color Maximite because it uses a similar BASIC
programing language.

How to install on a dos computer.

Boot up and see the C:> prompt.

Make sure you have at least ten meg free on your hard disk.

Make a directory called "mov-map": Type "mkdir mov-map" and press Enter.

Change to the A: or B: drive whichever is the 5.25 inch 1.2 meg drive
while in DOS. From the C:> prompt type "A:" and press Enter.

Copy all files to the hard disk: Type "Copy *.* c:\mov-map" and press Enter.

Type "C:" & press Enter to switch back to the hard drive.

Change to the MOV-MAP directory: Type "CD mov-map" press Enter.

Uncompress all the files: Type "unzip" press the Enter key.

All files will be expanded.

List of files on the disk:

AIRPORT  DAT   Ascii data base for all airports in the US.
COMUNKAT DAT   This file can be modified to suit your GPS.
MODULE2  EXE   Can only be run from with X-CNTRY. Do not run!
MODULE3  EXE   Can only be run from with X-CNTRY. Do not run!
RUNWAY   DAT   Ascii data base for runways!
X-CNTRY  EXE   Run this for the moving map.
PKUNZIP  EXE   The program that uncompresses the above files.
UNZIP    BAT   The program that call the above program.

Make up or buy an RS232 cable that connects your GPS to your notebook computer.
If you don't have a GPS get the cheapest handheld boat unit you can buy
with a NEMA 0183 RS232 interface. The guts of most GPS receivers are identical
regardless of the retail price.

These are GPS satellite data output sentences. They arrive every few seconds. Plain text.
 Any BASIC can read these if it can read an RS232 interface from
a GPS. The Maximite can do it. Lots of boat units are available with the RS232 interface
