Kevin Kraul was kind enough to send me a solution to this problem *if* you are  
using a math coprocessor (Thanks Kevin; hope you don't mind me posting this):
----------------------------
 static void interrupt InterruptHandler(void)
    {
       char     coprocessor_state[94];
             .
             .  // Insert other declarations here.
             .

       // Note: interrupts are disabled by the processor (80X86) automatically.
       asm fsave coprocessor_state;   // Save floating point state and regs.
       enable();   // Enable interrupts so other interrupts can be processed.

            .
            .  // Insert your code here!
            .

       asm frstor coprocessor_state;  // Restore the coprocessor state.
    }
----------------------------

However, this does not work when you are using emulation on machines without a  
co-pro.  Apparently this is a much more difficult problem.  If any one has a  
simple solution to it, I'd be glad to hear about it.

It seems to me, however, that Borland should have put instructions to do this  
in their library.  I mean, they went to all the trouble to make a special  
interrupt function type, why couldn't they have taken the last step and saved  
the floating-point state?

That same kind of crap happened to me last year when I ordered a hard drive
from Hard Drives International.  The sleazy representative jerked me around
for two weeks over a shipment I should have gotten in three days.  I finally
asked to talk to someone else that wouldn't jerk me around, after which I
found out that the drive they "had in stock" was really backordered.  That
was early in my purchasing days, I have since found a good company that
gets all of my business.  :-)

No.
A 256K SVGA card can already do this.
A 512K can do 800x600x256 (= 468 K) and 1024x768x16 (= 384 K), both
non-interlaced (at least, if your monitor supports it).
A 1024K can do 1024x768x256 (= 768 K) and sometimes 1280x1024x16 (= 640 K).

If you can, get a card with the Tseng Labs ET-4000 chipset. They're a bit
less cheap than the ones with a Trident chpset, but much faster.
Both Tseng and Trident cards are supported by almost every program
that uses SVGA (except for OS/2, for which no ET-4000 drivers are said to
exist yet).

Summary: HELP! Old Telebit Trailblazer problems

Organization: Information Technology Division, The University of Adelaide, AUSTRALIA

Can anyone help me?!

I swapped a 2400 modem with a friend and now have an
old Telebit Trailblazer. There was no manual (does this sound
familiar to you?) and there's this funnny problem.

The board appears as COM1 3E8H IRQ4, but Telix says its talking to the
board on COM3. When I plug in my mouse card which has 2 serial ports,
the modem appears as COM3 but I can't talk to it and my mouse (on
COM1) wont work. The aweful solution thus far is to unplug the serial
card eah time I wont to use the modem!

Now the Trailblazer has has some jumpers on it (ah ha!) but I have no
idea what they do and changing any of them stops it from working at
all. Here are the details:

The Trailblazer has a pc board number (solder side at the top)
10122-01 REV B. The serial number is 016130096. There are 3 sets of
jumpers 1) by the end of the 68000, three jumpers with a clip over the
lower 2. 2) by the slot, 6 jumpers with clips on 2-3 and 4-5, and 3) a
row of 3, just above the second one, with a clip over the rearmost 2
pins.

Would some kind soul be able to put me out of my misery with info on
these jumpers or some other way to solve the problem?

I tried changing the mouse serial ports address and IRQ but with no
success.

Thanks

Did you check your BIOS settings?  Typically, ESDI drives are identified
to the BIOS as Type 1; the controller handles the necessary translation.
When you put the Fujitsu drive on by itself, the BIOS did not have to
be changed, and all was well.  With _2_ drives, you must tell the BIOS
that you do in fact have two drives (both set to Type 1).
Change your BIOS type, then rerun the UltraStor utility.  It should find
the drive.

There's a quartz crystal that controls the whole computer.
The Dos clock is software- gets updated at the clock interrupts I
believe- so if some program shuts off the interrupts for a while...
Or if some program runs amok and writes to the few bytes where the clock
time is kept...
1 second/month= 1 part in 100,000 accuracy- why would they trim their
crystals to better than that ( or even that well)
There are also some Dos programs which dial up the US Naval Observatory
and set the internal clock form that I have one ( not tried) called
gettime which I think I got of wuarchive.wustl.edu- Try archie to find
it
but I remember there were a bunch of others as well
Just looked up- there are programs called stime,usnotime,nbscom12 which
claim to phone up th e Naval Observatory or NBS to set the PC time.
There is another one called clkdev14 which claims to keep the DOS time
in sync with the on board clock on AT's. ( I think these ar ein
msdos/sysutl on wuarchive)
I don't know what accuracy is required, but a phone call every day say
could set the clock sufficiently accurately

I also bought a 486-33 local bus system from Zenon.  The motherboard is a 
'Companion' board manufactured by Join Data.  I also got the S3 local bus
video (without the IDE controller).  I eventually returned it for a refund,
due to apparently unsolvable problems with the Colorado Memory Systems 
tape drive.  They would not allow me to return the monitor however, as
it had been 'special ordered'.


I replaced the system with a slightly better one (better case, power 
supply, keyboard, and the integrated S3 video/IDE controller) from Royal.
Royal's system used the same 'Companion' motherboard.  However, although
I have still had a few problems with the CMS tape drive (actually, the 
cable), it does format a tape.

I don't know if I got a bum motherboard from Zenon or what, but the
service and tech support from Royal was superior.

Good luck!

The ads I've seen, however, show the Occidental
systems using local bus video while the Zeos

to me that the two systems are not necessarily
of the same quality.  Has anyone out there used

According to the (probably newer version of the) setup manual that 
came with my RS/20... you may use the 1MB SIMMs.  The 100 nSec 
SIM modules are what is recommended for the RS/16 (not the 80 nSec).

You may install 4MB   using the 4 slots in "A"
                8MB   using the slots in "A" & "B"
               16MB   using all slots...   and
               10MB   using 8MB in "A" & "B" and 256k modules in "C"  
                          and "D"

Here's the rub:  (Someone correct me if I'm wrong...)

An EISA bus runs at 16MHz, but an ISA bus runs (usually) at 8 or 10 MHz.
When you plug an ISA card into an EISA bus, the EISA bus sees the ISA
card and lowers it's speed to 8MHz.  Thereby decreasing throughput
because of the lower clock speed.

The solution is to buy a EISA machine that has floppy & parallel &
serial ports on the MB (or on an EISA card).

Can someone in the know confirm/deny this?
