WOW! Great Timing on the infor for the Amstrad Website..
I can't believe you guys are on the subject of Amstrad PC6400..
A PPC640 ? At least that's what it was called in the UK.
I just purchased one at the local Thrift store
yesterday for $4.04
and when I got to the checkout line the lady told me it was half price
day so for only $2.02 I got this really cool Portable XT dual
720KB floppies, and a nice LCD screen..
It's a reasonable machine. I've been known to use mine as a terminal, or
to run a drive exerciser program (with the parallel port connected to
some signals of the drive-under-test), etc.
I have the manuals for it (somewhere), including the software tech manual
and the service manual. It's pretty close to one of the Amstrad desktop
XT clones -- it's even got the same ASICs in it IIRC.
Very impressive machine for 1987..
And it appears to run on standard D batteries for portable use..
I thought it was C cells, but I might be wrong. Do you have the 2 plastic
tubes that hold the cells together? I've never tried running it on
batteries, since it takes 10 cells (!) and they don't last long.
On the back are 2 power input connectors. The coaxial one is for a
12V-ish input, centre +ve, which is what I normally use (from my bench PSU).
The 14 pin DIN is a power input (all sorts of _regulated_ voltages) from
an Amstrad PC monitor. It's probably best to ignore this.
Oh yes, the power switch on the top is really a changeover from batteries
to external PSU. It seems a little odd at first.

I have one of these things. I wanted one since they started going on deep
discount in the late 80s, but I couldn't afford one then. My sweety found one
on e-bay for not a lot.
(By the way, if anyone has a dead ppc640 or 512 and wanted to sell me the case
and handle assembly, I'm interested)
It takes C cells and runs for quite a while on them, 8-12 hours. No hard disk,
no backlight to eat battery power.
I run Caldera DR-DOS 7 on it when I run it.
I can probably come up with the manuals - I have them somewhere - if someone
wants specific info from them.
