In Holland, the schematics were published in the "Elektuurz' magazine,
special edition. I can't find a date :

"Elektuur extra Computing", 2e speciale computer uitgave"

The schematics consist of 8 pages, signed John Ferguson, June 1983. 

I have this magazine and I can scan the pages if needed. Indeed, dutch only :)

Thank you all for any help that you can give me. I've discovered that
my board works, but keeps spuriously spitting out characters that are
either 7Fh or FFh via the serial port. I do not have a parallel
keyboard, so cannot see if that problem will disappear if I plug one
in. I've done a little work on using a PIC 16F84 to make a PS/2 style
keyboard appear as a parallel, but that's not finished. Once it is,
I'll have to find some way of connecting it up to a VGA monitor, as I
don't exactly have any other suitable display.

I've worked out where the boot rom is located in memory, and am
disasembling it to see if I can discover the ports, etc. For some
reason, this board fascinates me. There's so much at work there.

Did someone mention a bios for CP/M? I can see something marked SASI on
here too, could a SCSI ZIP100 drive be made to work with that? If there
are any resources that can be sent to me, I'd appreciate anything. I
cannot read dutch, however - for that, there's always babelfish, I
suppose.

For Babelfish you need OCR'ed data !

OK, I managed to scan both the sheets and the article. The quality
is not perfect, but well ....

I have put the file bbii.zip on my website. There is no link to it
on the page, so type in the link manually :

http://home.hccnet.nl/j.bus/bbii.zip

(for me it starts downloading, so you should be able to get it)

The text files page1.txt - page3.txt have been manually proof read,
the other text files are direct OCR output. If you have specific
questions I will be glad to answer them, but my time is limited, so
I don't think I will do the other text files myself. I will try to
help with translation problems, if there are any :>)

PS : perhaps it would be nice to put them on the web when you have
     translated them :>) There probably are more people interested ?

Have fun,
	Hans Bus

PPS : there is one more .jpg, with the component layout, but my web
      space ran out. Post when you have picked up the zip, I will
      then put up the remaining file.
