    4P CRT swap

    My 4P currently has the white CRT. Is it possible to simply swap out the white one for a green CRT, or does the green CRT require a different sweep PCB? Are the CRTs still available?

    Nice find! If you discover that you have duplicates of any of the official Otrona manuals, I might be interested.

    Does your machine have the optional 8086 coprocessor board installed?

    I have to take issue with this point. Osborne bundled CP/M 2.2, Wordstar/Mailmerge, Supercalc, MBASIC and CBASIC with their Osborne 1 in 1981. Kaypro did the same thing in 1982.
