That's a compiler (or library, actually) bug. You should be able to copy a

Sorry... I've only got two right now. And usually, I have one, but I had to

On Commodore Monitors for C128D.
If you can find one you would want to get a Commodore 1902/a, 1084, or 2002.
They support the RGBI (80 column video) as well as the split-composite (40
column video) the 128 produces. Magnavox produced much of the 1084 line and
had a Magnavox model available (something like professional 80 column monitor,
the front panel on mine is missing so I don't have the name). Regardless If
you want to use both 40 and 80 column video, best to get one of the
multi-function monitors, else you will need an RGBI and a composite montor
(which by the way the C= 128 can display to both simultaneously as they are
different video controllers at work.)
On CP/M 3.0+.
Really nice version; can read a variety of popular CP/M disk formats using
the 1571 disk drive. If you plan to use 3.5" disks I guggest you look for a
later version the the versoion supplied with the 128D, there are no support
drivers for the 1581 (can't boot of of it etc.)
Also "GO 64" gets you only to the Commodore 64 mode. you either place your
CP/M disk in the drive before power-up or after power-up type "BOOT" in 128
mode to boot the operating system disk. (note make sure the 40/80 column key
is down on power-up to ensure the 128 starts up in 80 column mode. :)

I know these programs exist. There are some for the Spectrum and ZX-81,
too. However, I could generalize and say they were all DOS-based,
written in Pascal or assembler, don't come with source code, have
poor documentation, etc. and I want to roll my own in straight portable C.
I'd rather make it general to handle old S-100 tapes, C-64 tapes, etc.
instead of just hard-coding one flavor. It should be ready in
the year 2010.

No, my point is that it's more useful to have generic tools to help
rescue old data. Sure, QuickCams are nearly disposable now. Cheap
$1,500 PCs include them these days. Five years from now, they'll be
embedded in cheap monitors. Ten years from now, they'll be in cereal
boxes. Unless the hobby of collecting computer junk is adopted by
Hollywood stars, I humbly suggest that it will be at least *more difficult*
for you to find spares for your original equipment than it will be
for me to find something that could deliver a bitmap by looking
at my punched card. :-)

There is a growing one for Commodre 8-bit aficionados at:
http://www.funet.fi/pub/cbm/
This FTP site has various shematics ROM Images, etc.
Copyrights seem to be a mute issue for the 8-bits, as no one seems to really
know who holds the Copyrights on the 8-bit Commodores (Escom?, Tulip?,
Visicorp?, Gateway 2000?, the former MOS Technologies?) It is a popular
thread on comp.sys.cbm.

Check out BOMARC SERVICES (http://w3.trib.com/~rollo/bomcat.htm)
Their catalog has 3,000 devices that they have reversed engineered and
sell the schematics for. They usually advertise in Nuts and Volts.
I remember when I was at Tengen in 91 or 92 and we were just getting
started on the Sega Genesis, we sent them one and they sent back the
schematics. It came in real handy, the only programming manual was
xeroxed, handwritten and translated from Japanese (badly).

<Oh come on. The 16 bit registers in the Z80 were hardly general-purpose

My comment was to point out that most of the micros were not register
poor like the 6800 or 6502 only that they really didn't use them well.
<The ARM was developed as a 32 bit replacement for the 6502 according to
<one rumour (from Acorn, BTW). They didn't like any of the existing 16 or
<32 bit chips, so they designed their own...
I've looked briefly at that chip and it's real simple and straightforward.
Never had a chance to play with one.
<The one instruction per clock cycle definition is daft IMHO. It shouldn't

<paths have the same timing.
I agree mostly save for at the time that notion was in vogue the maximum
clock rate was circuit limited in NMOS and CMOS devices so fewer clocks
for a cycle equaled greater speed. Most of the RISC proponents of the
time were talking lower transistor counts, clock frequencies, lower
silicon cost and higher testability than their CISC counterparts for the
same overall system performance. The concept was really applicable to
microprocessors as no engineer at the time could even conceive of
injecting clock at 100mhz in to a micro at a time when gate propagation
delays at the silicon level were greater than 10ns. The concept was
appealing when z80s were hitting the wall at 6mhz and 8086s were fast at
10mhz. Of course as Hmos-III and sub 1micron CMOS started to show signs
of going much faster...
Allison
<FWIW, it's been my experience that on problems small enough to be tackle
<by the J-11, an 18MHz J-11 eats the VAX-11/780 for lunch.
The PDP-11 is no slouch. I've used the T-11 part for some things and
even using the pokey 7.5mhz clock some tasks are faster than most
anything contemporary to it like the z80/8mhz even though the numbers
say slower. It's that CISC with superior addressing modes that put it
out ahead.
I've found the same but it's task dependant and also the 780 is always
doing more than the J-11 due to OS. I did get a chance to try that
once and the 780 was running nothing more than the usual background
tasks and it was close but then both are about 1mips. Same was true in
1978 when the 11/70 was put up against the 11/780. The 2vup and faster
VAXen made it a no contest in favor of the VAX though. As soon as the
task exceeds 64k or the user/task load gets up there the differences
start to stretch out with the vax ahead. A faster PDP-11 will always
have that disadvantage.

Just to flog the horse, my point was that my C code will deal with
a bitmap. It doesn't care which technology produces the bitmap:
today's QuickCam, tomorrow's Java Ring, 2010's 3D scanner.
A friend of mine has a joke that goes something like "In ten years
we'll have a wrist computer with the horsepower of today's $5,000
workstation, voice recognition, holographic memory, etc. but there
will still be an obscure way to get back to the C: prompt."

The MIPS chip in a Nintendo is a cut-down version of the versions used in
SGI and the Nintendo is a long way from an SGI sans keyboard, harddrive,
etc. I can't remember all the differences now, but I discussed it with SGI
last year when I was looking for a fast CPU for an embedded application.
We have lots of SGIs (of different types) here, so MIPS devices were one
of the obvious things to look at. It's definitely RISC, though :-) The
eventual choice was StrongARM, though the project never got built.
