The parallel interface (or Centronics) was not an option but was used on a basic model 7900 or 8001 as receive only cheaper printer option. The cooling fan was installed on the printer-only of the same series, the 4560. Now with the Cooling fan driver I quickly made to replace the one on prototype board. Standard was the TPWR sold with only the small micro-floppy interface as the one in the Haata’s Flickr Album. As terminal, can be configured in full duplex, the characters typed on the keyboard are only sent to the other device, or in half duplex, the characters are then sent to the other device AND reinjected by the UART in the receive buffer to print a local copy at the same time. (see EPROM D35)Ĭan be used to receive data to print and/or to send data to a mainframe or even to another TPWR. The serial interface RS232 (or V24) combined with the micro-floppy interface was an option, FACIT add then KSR for Keyboard Send & Receive to the model name. The CPU board Facit 8121, microprocessor 8088, 7 EPROM’s 2764 8Kx8 for the program and 24 Static RAM 2Kx8 Toshiba TC5516 or NEC µPD449.
More, the foam used as sound absorber inside de covers and on the mechanical frame was falling as dust when touched.Ī few pics at the beginning from the bottom cover to remember me the wiring modifications I made 30 years ago. That’s how it looks now, but not one month ago, I just put it in 2002 in a plastic bag, not cleaned after using it for 5 years as printer.
Another typewriter in the same series as the 8111 presented by Haata photos-videos-f64/facit-8111-2-typewriter-t12424.html and the typewriter/Invoicing machine 6480 presented by purdobol photos-f62/facit-6480-typewriter-calculator-t17719.html
