Subject: Re: [Homebrew_PCBs] TV Typewriter: Custom G10 copper clad

Aargh! You reminded me of my first encounter with the time sharing service that our company contracted with in the 70's. Dial up, 300 baud, acoustic coupler. I/O was a KRS 33 Teletype.  No operating system, just a Monitor.  I am convinced that that situation caused many of our employees to be wary of the PCs when we finally got them.  That time sharing system was so gruesome that it scared people away from wanting to use computers.

Oh yes! Mine had to be fixed with a velcro tape to the telephone earphone, 75 and 300 Baud.

This reminds me of my first modem (circa 1985). It was not fast but it worked at the time to connect to the university network.
