Recently I went though the content of an old hard-disk I found in the attic.
Disk wasn't used since 1995...
On it I found a collection (some 60 images in GIF format) depicting floor-plans of various models of space-craft all labeled as "Defrog ship-model".
E.g "Defrog ligth cruiser", "Defrog log-range scout", "Defrog Assault Troop carrier", etc.
Most of the ships where military. A few cargo vessels with limited passenger capacity. And a diplomatic shuttle-craft that also had a passenger cabin.
All descriptive text in the drawings was in English.
There were only floor-plans, showing the deck-layouts and included basic furniture like beds, chairs, tables. From the furniture and the layout of bathrooms, etc. it was clearly all designed for humans. Or very humanoid aliens.
I have no idea what "Defrog" means. Could be the name of the manufacturer or maybe the name of the nation/empire/organization to which these ships belonged.
It all looked quite interesting but I have not been able to find any more references to "Defrog" anywhere.
Unfortunately I can't provide a sample picture. That hard-disk died on me while I was trying to retrieve the content. No surprise as the disk was about 30 years old.
I must have downloaded these images from a BBS, a FTP site or USENET group between 1988 and 1995. I can be fairly certain about that time-frame because I can recall I bought the computer with this hard-disk in 1988 and I replaced it in 1995.
Does "Defrog" ring a bell for anyone? I would like to know more about these ships.
PS. On request of Valorum I added a rough sketch drawn from memory to give you an idea what these floor-plans looked like. Background was white, outlines, hull, walls in black. Furniture in blue and green (this varied). For some ships having multiple decks 2 or 3 decks where displayed in one image. Or for some others each deck had his own image. All images had a small legend bottom-left.
