One find this week, a C128. These new rules about the electronics
manufacturers taking the responsiblity for discarded hardware doesn't seem as
bad as it might, since the recycling station now has a dedicated skip for
computers, home electronics and CRTs.
However, the C128 only starts up with a black screen. The common VIC border is
visible, but the screen is entirely black/grey instead of brown, and no text
or prompts. What could be up here? Broken kernal (is it spelt with an A on
Commodores?), broken BASIC, broken VIC?
BTW, there's been a demo party in the building where I live this weekend. Lots
of Polish hackers sleeping in the corridors and the garden, lots of C64s, and
the things they did with them! Absolutely amazing! Voxel landscapes, fire
effects, resolutions which I never thought possible of a VIC... Definitely
worth visiting if one comes to your town. This was just a small party, though,
mainly C64, instead of the "3000 PC users play Quake 3 Arena" parties common
today.
They also ran some Game Boy demos, but that's not on topic. =)

*Black/grey* instead of *brown*? The C128's system colours are light green on
dark grey with a light green border in 40-column mode, and cyan on black in
80-column mode. What's the status of the 40/80 COL key, and what happens when
you force the unit to 64 mode (hold down the C= key as you turn the unit on)?

It's been some months since I powered up my C128D, but I certainly seem to
recall its screen being brownish. Are you certain you've not pushed the green
button on your 1084 or 8833?

There are two major products that come from Berkeley: LSD and UNIX.
We don't believe this to be a coincidence.

Why, I've had a Game Boy for over 10 years, and IIRC, it's a 6502 based system.

No. Z80, actually.

Nope, the Gameboy uses a modified Z80. Nintendo has made a habit of using
slightly modified versions of common processors to discourage piracy, for
example, the NES uses a 6502 chip with decimal mode removed and sound
support added. Boy, i wish there was a "classic consoles" list out there.

I was on an emulation mailing list last year that discussed the basics of
console microprocessors. However, the administrator moved it to their own
domain and I never heard anything again. I would welcome any discussion on
this list, classic computer or console. They both share a common history.

I see I failed to point out that they were for the Game Boy Colour, which is
a much newer system, though the only difference to the classic system is the
tacked-on colour support.
BTW, the GB is not based on the 6502, but on a particular Nintendo Z80 with
special sound registers. The NES uses a 6502 with similar features, however.

New subject: Broken C128 --> Gameboy CPU = ~Z80
The old and new Nintendo Gameboys are based
on a custom cmos Z80 derivative that is missing the
shadow "prime" registers and IN/OUT instructions.
