1. PASCAL FOR XENIX
I heard a rumour that Borland's "Turbo" Pascal would soon be
available under Xenix-80*86.
Does anyone have any further information on this or other
Pascal compilers for Xenix?
(I know Microsoft have one. Last I knew, it was 80286 only.
What is the latest?)
Compilation rather than exec'n speed is probably more important.
2. VPIX
We have VP/ix (Controlled Release) under Xenix-386.
It seems rather buggy (some documented, some not).
Has anyone written any terminal support (other than the
distributed VT100, ANSI and Wyse[56]0)?
The documentation says that various
operate_on_(specified)_multiple_objects
attributes (insert/delete multiple lines/characters)
are mandatory. Is this so? If so, why not call the
appropriate insert/delete single-object attribute multiple times?
I think many terminals do not support these features.
I am fiddling with a driver for Heath/Zenith 19
(it may be old but it has F-keys and an ANSI mode, so it looks
like a good one on which to practice).
We also have Esprit I's and Esprit 6310's, plus Tatungs which
emulate VT100's on order.
Our machine is a NEC Powermate-386, which came with a NEC
"Advanced (Ughhh) Graphics Card Plus". This is one of the
EGA-compatible cards that isn't quite compatible,
so our console now has a monochrome Hercules-compatible
card. This fills the screen with rubbish when MS-WORD is
invoked under vpix. What have I done wrong?
3. GRAPHICS DRIVERS FOR XENIX=*86 CONSOLE
A couple of weeks ago we took delivery of SCO's
upgrade of the Development System, -286 v2.1 --> -386 v2.2,
which includes CGI.
However, CGI is a lame duck without drivers for Herc. mono.
or EGA graphics (you call CGA "graphics"?)
Has anybody out there got drivers for these and other devices.
PS I DO have a home-grown Hercules driver, based on the sample
CGA driver listed in the Xenix "Writing Device Drivers".
I haven't looked at incorporating it into CGI - it may not be
possible because it cannot return a segment selector to the
user program to enable the user-program to share the video RAM.
You can have it, but I'm not sure how to get it to you:
- multiple international mailings are expensive
- am I permitted to broadcast it to the net, SCO ???
