    Sorry, but that was my best response.

    One thing I was curious about with the eaZy PC, but didn't have enough programming skill to test, is if it implements the monochrome 640x400 graphics mode that its CGMA video chip supports. It has 64K of video RAM, so it should be possible to use. When I installed Windows 3.0, it suggested the AT&T PC6300 driver, but that didn't work.

    If you dump the BIOS to a file using debug and make it available, I'd be happy to check for you if it attempts to handle more video modes than the standard CGA modes 1 through 6. That's usually an indication that it supports 640x400.

    Alternately, you can sell me the system for the cost of shipping and I would be happy to poke around the actual hardware.

    I wonder if anyone knows what the pinout of that expansion connector is. It looks all ready to take a Tandy Plus card.

    SOLD!

    I have another Zenith computer with that same pin header expansion connector, except internally -- the Z-148. Back in the day, Zenith sold an adapter to convert it to a standard ISA slot, but good luck finding one of those these days...

That phosphor has a distinct bluish cast to it.
    It's a softer white as well. Easier on the eyes.

    I'll have to crack open my z-148. I don't recall seeing that. On the other hand, it's been a long time since I opened it up.

    I really enjoyed your YouTube video on restoring that computer.

    Usually, but I remember there being a lot of inconsistency in those "whiter" phosphors. Some cheap VGA mono monitors would say "paperwhite" on their box but so far as I can tell they were using the regular old blueish TV phosphor, but higher end monitors would use a nicer warm-white formulation.

    Of course, given a choice I'd still probably prefer green.

    Some of the old Zenith & Compaq amber monitors were nice. Have to say I'm more comfortable with green.
