    I picked up a green CRT from Jay's site, and made the swap this evening. Works great! While I was in there, I proactively replaced the large RIFA cap in the power supply.

    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?

    Look for a shorted tantalum cap on the 12V rail. I had the same problem on a 8" Mitsubishi drive on the 24V rail.

    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.
