    Anyone know what kind of daughterboard is on this Kaypro?

    Looks like the 8088 coprocessor board as in the Kaypro 4/84 Plus 88: http://q7.neurotica.com/Oldtech/Kaypro/Kaypro488.html The board was made by SWP Microcomputer Products, and available for several other systems: https://retrocmp.de/kaypro/1985-08-20_SWP-Co-Power-88_kay_OCR.pdf

    Newbie questions about the Northstar Advantage 8/16

    That's normal. It's waiting for a <RETURN> (load from drive 1), D2<RETURN> (load from drive 2) or S<RETURN> (load from serial port).

    xtar - what am I doing wrong?

    You don't mount the IMD file. Insert the file into the drive and 'tar -tvf /dev/fd0'

    I unearthed three Osborne 1's from storage, and now I have some mysteries to solve!

    Your first system in an "Executive-style" case is actually the second version of the Osborne 1, often called the Osborne 1A. The Executive had 1/2-height drives on the left side of the CRT. http://q7.neurotica.com/Oldtech/Osborne/Executive1L.jpg...

    What Mainframe and why?

    I never saw that, but I do recall guys who made a nest in the cable trays to grab catnaps.

    Looking for Osborne 1 Screen PAC and old software respositories.

    Al Kossow is a member of these forums. He may be willing to scan them, if you ask nicely. :)

    Looking for Osborne 1 Screen PAC and old software respositories.

    David: I have the Lornes-special-osborne-software.zip file. I'll send you a DM. The Computer History Museum has a schematic for the Screen-Pac: https://www.computerhistory.org/collections/catalog/102665657 You could try contacting Al Kossow at Bitsavers to see if he has it scanned.

    TRS 80 Model 4 Should I buy?

    If you power up the Model 4 with no diskette inserted, or just press the RESET button with no diskette, it won't display anything. If you hold the BREAK key while doing a RESET, it should start up BASIC and you'll see text on the screen. You could ask the seller to try it.
