The government has focused its efforts on severing the communications that make opposition efforts effective. When they initially severed the public telephone system, computer operators used internal private line systems to maintain communications. With martial law, these too were shut down. Now the primary modes of communication are either by mail or by courier. A floppy disk is easy to hide in a package or carry unobtrusively.
Personal computers are now widespread in Poland, acquired both legally and by smuggling.
There are an estimated 500,000 personal computers in Poland, with Sinclair and Amstrad being the most popular. There are an estimated 700 illegal publications being generated by everything from matrix printers to laserwriters. Nearly two thirds of the non-violent crime in Poland is associated with illegal press and opposition activities. The government has had to choose between the serious economic damage that would result from eliminating computers and their elimination as an opposition tool. So far, they have been forced to allow the continued use of computers.
