I had worked on other systems for course calculation, vehicle
information, etc. But long term exposure to radiation is to be
considered a problem. On solution was the reed switch
electro-mechanical really just a binary calculator just for that
purpose. Even with a modern system this would still be a good back
up.

The choice though in the 1990s was the motherboards of a HP 100. I had
one with a 5 and a 10 Meg flash card. The screen and the keyboard had
leads that could be extended, with a transistor etc. The over all
size than was 3 in. by 6 in. with the card in. The placement had long
been decided by what was know from the book The Space Environment
(1969), as many gram/cm for as many cm as possible. The place for the
computer and for sleeping was where the most shielding was.

The knowledge moving beyond simple circuits came from Radio Shack Hand
pocket hp1 24 digit display of possible 80 characters. The chip of
most importance was the on used to interface with a tape drive. The
name by function is a high volt bypass.

This chip is used in pinballs and video games for feeds to reed
switches. I vended pinballs and video so my knowledge of circuits
grew. Having to fit circuits with transistors because the
manufacturer had his own numbers printed on the originals or they
just plan fried. Designing is then fitting together inputs to outs
etc. Pinballs use 8 by 8 grids for lights and switches with 3
generation of transistors for powering the bumpers, thumpers, and any
thing with a motor. With the use of by now an old friend the high volt
bypass or what ever it is called in the IC handbook today. The one
thing I know helps in working on machine design is to remember it is
digital logic. Once it does or is not working remember it is still
"Operating logically" but something has changed.

One of the companies big in computerized heating and air-conditioning
systems for skyscraper or large buildings is an ex-manufacturer of
pinballs and video.

I had figured about 10 years for this whole project. The computer and
programming portion being the cheapest would first part to work on
every time money was low. I had for the HP 100 QBasic, VBDOS, and
MASM 5.10 for programming languages. The VBDOS assemblies to about
2/3 the speed of assembler or a littler slower than C/C+. For get
making little windows it is just faster. Any thing that needed to be
faster or that was for input output would be from MASM 5.10. The other
parts of the project I had worked on for 17 years. That would be this
year.

I would still like to do the whole project myself.

Some day in space some will do project like this
or if we are in space we will be just spam in a can.
 
Literally.

Beyond some scientist doing experiments, there is
no reason for anyone go into space unless they could
do everything so that their life there could continue
unaided.
