Fun scene in Deutschland 83 has a HVA geek trying to use a 5.25" floppy they snatched from NATO into a Robotron A 5210's 8" drives. After hacking around a bit, he managed to read the floppy and it spits out a bunch of numbers in sequence. "It is encrypted" he says as the screen shows columns of numbers scroll by.
Shortly after, this flashes on the screen briefly [/g]:
OK
10 CLS
20 FOR I = 1 to 64
30 FOR P = 1 to 6
40 FOR Q = 1 to 5
50 A=48+RND(1)*9
60 A$=A$+CHR$(A)
70 NEXT Q
80 A$=A$+" "
90 NEXT P
100 PRINT " ";A$:A$=""
110 NEXT I
OK
I read somewhere on this excellent website before they (the DDR) had an IR line of sight Morse code transmitter in active use too, albeit slightly more recently.
The page cites “Louis Meulstee, Wireless for the Warrior” as its reference for a nickname of the device, and also links to an excerpt of it that notes that a similar transmitter was actually Czech. I suppose this Louis Meulstee may have been who figured out it was DDR, but without buying that book I guess I won't know how.
