But I have less covers than machines. So this would be cool. Before I came into vintage computing I played with teleprinters. I still have a nice collection of ca. 20 machines. Back then I created something I called "TelexPhone" - a hack consisting of a real (!!!) V.21 modem and a PIC microcontroller which is still used by some hobbyists to do dialup telex communication via telephone lines. The system was fully transparent with no intermediate data buffering. I really liked it. www.telexphone.net is a website about that. Later there came a guy who wanted to "cooperate" doing a new design. But after exactly one meeting and me (idiot) telling him the handshake specifications - I never heard of him again. A few months later he invited to the presentation of his new design. Which at that time did not work reliable. This is years ago but I still feel betrayed for my idea. They now sell it as TelexPhone 2. When I planned a redesign I thought about an FPGA and/or TDK modem chips and a modular design. It was considered too expensive. And now there is that HUGE masses-of-features modular and expensive multi board thing using lots of AVRs - and TDK modem chips.... Ah, and I wanted to use SMT components - impossible! - the new system has SMT stuff and nobody worries about that... Sometimes I still think of designing something that outperforms the crap with respect to all aspects while being significantly less expensive. But it's probably not worth the work. I don't like to post with bitterness. But your remark about teleprinters still hit me. Philipp -- Dipl.-Inf.
