Thread: Davidge DSB4/6 Z80 board

  1. #1

    Default Davidge DSB4/6 Z80 board

    Looking for Docs and disk images for the Davidge DSB 4/6 Z80 board.
    Also the SCSI interface board.

    CP/M, MP/M

    Does anyone know about this machine?

    IIRC, they were used in CNC applications. I've got some Davidge floppies, but it may take some time to find them.

    I've got two Davidge disks--one 96tpi 5.25" and the other, an 8" marked for the 4/6. The 5.25" appears to be for a drill machine--lots of Gerber files:

    12K free on drive B:
    I suspect that the 8" will be similar.

    I have a complete machine somewhere.
    I see a board and manual are listed by 'k-systems' who has the nasty habit of doubling their price if an item is watched

    I see the bitsavers stuff. I'd like to add to that Al.

    Chuck if you'll send me those disks I can image them and make them available, then return them.
    I've got my 5.25 and 8" imagedisk system running good now.

    Yeah I saw the ebay listing, way overpriced. I got a complete system for $70 with 2 floppies, PS, cabinet.
    And it has the SCSI adapter board but the drive has been pulled. Do you think that was an ST225N or something?

    I'll image them for you and post offsite. I don't let my originals leave here.

    I recently picked up a PC/XT style case with a Davidge DSB4/6 board and SCSI bridge board mounted in it. The hard drive was missing, naturally. If anybody were to point me towards a working floppy image, of any flavor, I'd be grateful. Didn't see anything obvious in the Maslin archive.

    There were two on ebay from the same seller, I guess you got one and I got one.
    Yours is slightly different though if I remember right, some additional boards or something.

    We should stay connected on this project.
