Paravant RLT-88 computer?

I didn't get any responses to my question about the Paravant computers. However I decided to post some pictures and see if that sparks any response so here we go. <http://www.classiccmp.org/hp/Paravant/top.jpg> This is what it looks like. The charger is in front of it. The charging cord uses a "Cannon" plug as do all the I/O cables. <http://www.classiccmp.org/hp/Paravant/RH%20end.jpg> This is a picture of the right hand end showing the charging port, 2 serial ports and another unknown port. At the top right corner is the knob that locks the tilt screen in position. <http://www.classiccmp.org/hp/Paravant/LH%20end.jpg> This is a picture of the left end showing the removable cover and one of the RAM disk memory cards. The way the system is currently configured these cards act as the A and D drives. (The main drive is drive C.) Does anyone know anything about these cards?? <http://www.classiccmp.org/hp/Paravant/LH%20Open.jpg> This is a picture of the left end with the cover removed. It shows the two memory cards as well as slots for two more. Surprisingly the main battery in the computer is still good. Unfortunately the batteries in the memory cards seem to have died since I can't read the cards (they report General Drive failure). I would like to have seen what the program that was loaded the machine did. It was something called Navy EO. The good bit is that the program to reformat the cards is in the main computer so the cards can still be used. <http://www.classiccmp.org/hp/Paravant/open.jpg> This is what it looks like when opened up. The keys all work fine but there's no touch typing on this keyboard! The keys all require a deliberate press. <http://www.classiccmp.org/hp/Paravant/screen.jpg> This is a screen show showing the operating system (MS-DOS 3.21f) and a directory listing. This thing is built like the proverbial brick S***house! Anybody ever seen anything like this before? Joe At 09:01 PM 9/25/05 +0000, you wrote:
