Xpantastic!

Hello-
I'm trying to service an Xpander with intermittent problems .
The CPU board & power supply board are radically different than what's
described in the service manual;  I'm guessing this is one of the
Japanese units.
Does anyone have documentation for these?  (the "First Edition"
service manual that's available in various places online is only for
the US unit).

Thanks.

I have a copy of the service manual that I bought from Mark Glinsky 
(www.markglinsky.com/ManualManor.html); unfortunately I can only confirm that it 
is the same manual you already have, except that you can actually read the 
schematics and board diagrams. I'm sorry that isn't very helpful...

I don't suppose you could post some photos of the CPU & PSU boards?

Best of luck,

John :^P

Cool, thanks for that. The CPU board is the same as the one in my Xpander, but 
the PSU board is completely different. What's the serial number on the back? I 
have some notes on the "American vs. Japanese" question at 
http://johnp.net/blog/2006/01/19#japanese-vs-us-on-ah .

Photos of my boards are at http://xpander.geek.nz/my-xpander.html , FWIW.

Cheers,

Hi John,

Please, can you check pp. 36-38. Are there duplicated or missing pages?

In my manual it appears that page 37 is missing, if I remember 
correctly. I would like to get a copy of the missing page.

Kind regards,
Tiitu.

*cough* Er, to be honest I hadn't bothered to compare the schematic to the 
physical board. But you're right; 8K static RAM chips in the diagram, and 2K 
static RAM chips on the board...

And since the serial number on mine is 700290, it looks like I have a Japanese 
Xpander, although the plate on the back doesn't say where it was made. And the 
PSU board clearly has "Made in U.S.A." on it. Interesting.

And I guess our chances of finding schematics of the "last edition" processor 
(and other?) boards are approximately zero...

Cheers,

John :^P

As I said in my earlier message[1], the table of contents (itself missing from 
the ftg.co.uk PDF) lists page 36 and page 39, but nothing on pages 37 and 38. My 
scan of the manual has no more pages than the ftg.co.uk scan (apart from the 
TOC), although the quality is much better and the schematics are a lot easier to 
read (not least because they were printed on A3, or whatever the US equivalent 
is called).

There is no page 37 or 38.

Cheers,

John :^P
