Past

My first computer in 1988/89 was Schneider PC 1640 with Intel 8086 and 640 KByte memory and 16 Color EGA graphics with little sound. Starting with dataphone Modem 300 Baud, upgrading to 2400 Baud Modem in 1991. My local Z-Net mailbox provider was based on Amiga, 3 phone lines. Those days my favored e-mail agent was X-Term (CrossTerm) for M$-DOS-3.3; did my first programming with Turbo-Pascal-3.3. Starting study in 1993 in Berlin, choosing new username/login frehberg the first time

Did my first Linux Installation in 1994, based on 20 floppy disk Slackware-Distribution, switched over to SuSE, and later to Redhat. From time to time I get to know some tricks or workarrounds being published at www.advogato.org
