I had a friend who was both blind and without hands. He wanted to write. Some kind of organization gave him a PC XT 286, which was a computer intermediate between the PC and the XT. It lived in a PC box, but had a 286 processor. IBM didn't make many; rumor says they were using up their PC cases before they got to making the AT. (Yes, they existed: https://www.old-computers.com/museum/computer.asp?c=260 )
Since it was an orphan of sorts, repair parts were hard to come by. He'd learned the program (both reader and word processor) and didn't feel like changing -- I quite agreed when I tried to shoehorn some other screen reader into a 386. It involved a special output card, as well, The company had disappeared without a trace. So I ended up maintaining an old, scarce computer for about twenty-five years.
I made a new keyboard for him. He'd learned to use a peculiar keyboard with a modified typewriter, so I made a larger copy mated to a regular keyboard (I had to get access too, for maintenance.) Thank heavens Windows hadn't been created, because I haven't the faintest idea of how to make a mouse. But that PC-286 was his friend and muse, and he wrote a lot with it. (I have a novel he did. Rather Wodehouse, it was.) And I kept it going until the day he died.
