I had some weird thing by Olivetti - it was a PC not a typewriter
Had an RF output so I used a portable TV as the monitor. An integral keyboard casing housed the "motherboard", with an ancient 8086 type processor and a single floppy 3 1/2" floppy. Used DOS and had something called GEM which supposedly was a graphical display. And then there was the hideously noisy dot matrx printer
