The 6800 indeed had HCF and while I forget the opcode
(not a regular 6800 user) it was real. Basically if
the opcode was encountered the chip executed bus cycles
and did nothing else till reset. Story then was it
enabled some level of factory testing of the die for
the is it even alive test.

I'd suggest finding a VHDL or Verilog implementation, and see if
that provides any insight. Also, Google for '6800 undocumented opcodes'
(no quotes). There are a number of hits. Most seem to indicate that
the undocumented opcode (no value given) causes the processor to go into
a mode where there are no instruction fetchs, but the address bus runs
incrementing bus cycles.

Anyone here familiar with a .DAI extension chip layout or Schematic file

I'm guessing the formats are quite different, but if you want to
see a WPS-8 to WordPerfect conversion program:
http://www.srv.net/~kth
It might be a starting point for something like this.

Interesting. As far as I know wps-plus is compatible with (superset
of) wps-8.

WPS-80, WPS-PC (a non-DEC implementation) did document transfer and
maybe import from DECmates
and ran on Rainbows and PCs. I don't know if the All-in-One WPS format
was the same as the
PDP8 based stuff -- but it may be.
The company Exceptional Business Solutions seems to have dropped from sight.
I don't know if there's any way to legally get a copy of the software.

Hi Bill,
Thats for the info. Is WPS also formatted the same as Word 11 ?

Word-11? Is that another name for WPS-Plus?
(WPS-Plus ran on PDP11 and VAX. Very very slowly and poorly on a
PDP11 because of the Virtual Disease -- you can't write a program for
a 32 bit platform, drop it into a 16 bit platform using essentially
the same architecture, and expect it to work sensibly. It's written
in one of the world's most obscure programming languages -- Koala,
named after K.O. who inflicted it on DEC.)

I wasn't sure on that, I figured maybe WPS evolved out of Word-11.

Word-11 was writted by DPD(?Data Processing Design?)
to bring WPS-8 capabilities to the PDP-11.
Originally written in basic, it was later partly recoded
into something else that compiled into executable code
(probably macro and basic+2) to speed it up.
DEC later bought it and renamed it to DecWord, iirc.
It could communicate with a WPS-8 system and transfer
files, but they didn't used the same file format.
It was similiar, but Word-11 was based on 8-bit chars,
while WPS was based on 12-bit chars.
I once started a program to convert Word-11 files to
WordPerfect, but don't know what happened to that
version. I don't have any Word-11 files anymore
anyway.

I used Word-11 (from the company MASS-11 I thought) back in 1985 or
so for some reports. This was under VAX/VMS. I suppose that, for its
time, it was not too bad. I was glad to upgrade to TeX though!
I don't remember anything by the name of DECword, but there was
a DECwrite. DECwrite bore no resemblance to the Word-11 that I
knew.
As for the original question, somewhere I have a set of
3.5" floppies that claim to implement WPS-PC (or some
not entirely dissimilar name). I can probably dig them
out at some stage if anyone cares enough about them
(and I can find them :-) and they are still readable :-( ).
From what little I do recall about those floppies, it
looked like a DEC product.

DECwrite was a GUI document creation program for VMS/Xwindows only.
According to rumor it was based on a very very ancient version of
FrameMaker. It did become reasonably capable (certainly better than
MS Word of that era) before it was canceled. We used it extensively
in the DEC network architecture group (replacing Runoff), which may be
one reason why DECnet Phase V specs are not available anywhere.
DECword does ring a bell, but it sounds like a late name for what was
WPS-8. The PDP-11 and VMS analog was WPS-Plus, and that was written
from scratch, in a very short amount of time, at DEC.
I never used it
on VMS, but did suffer with it on a PDP-11 (Pro under P/OS, in
fact).
It worked, and it was reasonably functionally compatible with WPS-8,
but the performance was pathetic.

I'm not sure... If I ever find another set of WPS-PC I'll take a look.
I know I have WPS-80 (the CP/M version) and I'm not sure if the format's
different.
There was some support of DEC/dx file transfer with WPS-11... and IIRC
DECmates.
