    Default Z80 Trivia question!

    Hello folks,

    I read this a couple of days ago somewhere, and I don't remember
    which computer(s) was listed:

    Besides Zx80/81 what other vintage computers used a Z80 cpu as
    a video controller chip!

    Perhaps the Jupiter Ace as it is almost the same thing as a ZX-81 but with Forth?

    I think the PDP 11/93 (the last one) did.

    Unrelated, but still z80 trivia, I hope:

    What, if anything, or nothing, happens if Z80 leaves reset and /NMI is grounded,
    soldered hard for example.

    There is a superb tutorial on the ZX81 Video Display System by Wilf Rigter that you can all read about here

    Not sure what else uses it as a video controller.
    But the Tandy Model 16 uses a Z80 as an I/O controller.
    (CPU is a Motorola 68000)

    Yes, I think the Hardbox interface which connects a Corvus hard drive to a PET also uses a Z80. At least it was no 6502 design when I looked inside one.

    But this is not quite what Ziloo asked about.
