Aw, that's too bad! The original Model I (CADET) 1620 had a console typewriter (was it based on the IBM Model B electric?) that gyrated enough, particularly on carriage returns, that made you wonder if it was going to fly to pieces at any time. It was all part of the experience. What did you do about the 1620-specific keys? I don't think that record mark or R-S was a keytop legend ona Weheelwriter... --Chuck
Re: Daisywhell typewriter emulating a TTY
To all, The Computer History Museum's IBM 1620 Jr. project has already done this. We have converted an IBM Wheelwriter 1000 electric typewriter into a computer terminal. The conversion consists of a custom PCB with an Arduino Teensy 3.5 microcontroller which is physically installed in the typewriter, electrically in-between the keyboard and typewriter motherboard, with custom firmware. The initial work was to create a robust substitute for the IBM 1620's console typewriter. However, software changes are being completed this month to extend it into a general-purpose, easily-adapted, ASCII teleprinter. We demoed the device as part of our VCF West display last August at which we took 1st Place in Best of Show and 2nd Place in Restorations/Replicas. We will be making all of our design files, software, and documentation available free to the classic computer community. To whet your appetite, here's the step-by-step, illustrated guide for the physical conversion of the typewriter: https://github.com/IBM-1620/Junior/raw/master/docs/wheelwriter-adaptation-instructions.pdf We'll be posting a formal announcement of this device within a few months. This work has been done by Joe Fredrick, Steve Casner, and myself.

Oh how we used to dream of having one of these back then! We do have one in the museum's collection... although have not attempted to power up to use.

Well, there are Qume and Diablo. Diablo was bought by Xerox, so some of them carry that label. Most of the stand-alone versions had serial (RS-232) ASCII interface. I've given a couple of the Diablo KSRs (that's what the Hitypes with the keyboard were known as). I didn't care for them much--no immediacy of sound and keypress--the two seem unrelated. Daisywheel printers are incredibly difficult to get rid of--nobody wants to pay shipping. I got rid of the last one by throwing in a complete system with it. Still have a NEC Spinwriter mouldering away. --Chuck
