Subject: Borland TDebugger and '386 problem
As an answer to the question from Philippe :
Borland has a patch for some bugs in the TD-package. It is in the file
PD1:<MSDOS.BORLAND>TDPATCH.ARC and has a complete help and a very clever
patch utility (with a description of the utility).
It is true that the bug doesn't appear on all 386 machines, the reason is
in the PATCH file.
So, you don't have to worry, it's surely not your computer that's bad.

Subject: Serial port to Keyboard Buffer Driver needed
Hello,
I am looking for a program that will take input from a serial port and
place it into the keyboard buffer, to make it look like it came from the
keyboard. I want to connect a LS-3000 bar code reader to an IBM PC
running dbIII, scanning in one of the fields to search on. I realize that
there are physical ways to connect a bar code reader in front of the
keyboard, but we have 200 scan guns, and equipment to go with.
Please reply directly to me and I will summarize to the net.
Thank YOU!

PROCEDURE Zeller(d: DATE): WEEKDAY;

Post: true
zeller(d) ==
let m1 == month(d) - 2,
y1 == year(d)
in let m == if m1 < 1 then m1 + 12 else m1,
y2 == if m1 < 1 then y1 - 1 else y1

What's going on?
The first catch in this function is February --- it's an 'odd man
out' as far as the months go, so let's redefine the start of year as the
1st March, then we need only worry about leap-years in the 'year' part of
the formula. Next:
We want a function which gives a mapping: 1->2, 2->5, 3->7 etc ie the
number of days ''extra'' over a 28 day month. This is the '((26 m) -2)
truncate 10' term. To this we have to add the offset into the month so that
when we look at it mod 7 we have a mapping to weekday. Oh by the way this
term also gives a constant offset of 2. This chap Zeller was very clever
at hiding it!
Unfortunately it isn't that simple: there is an extra day in each year
(mod 7) so add y (the year in the century). Right so far, but leap
years? Well *within* a century these are regular -- every 4 years, hence
y truncate 4.
Ok so why emphasize within? well centuries are only leap-years if
they are divisible by 400. We've already divided by 100 to get c so our
term becomes c truncate 4.
Now about other centuries: 100 mod 7 = 2, that is to say the -2c in
the original formula. Catch is some programming languages do strange
things on Modulus a negative number (Modula2 in particular) so let's use a
positive term instead: +5c gives the correct result.

VAR
k, m, C, Y, temp: INTEGER;
BEGIN
k := d.day;
m := INTEGER(ORD(d.month)) -1; (* Really -2, but enums start with 0 *)
(* Which either proves that Modula-2 is innappropriate in this

temp := d.year;
IF m < 1 THEN
m := m + 12;
temp := temp - 1;
END;
C := temp DIV 100;
Y := temp MOD 100;

Subject: Day of the Week Algorithm
This is in reply to the day of week algorithm request. This has been
taken from an old HP 45 Applications book.
Let d = day of month
m = month, with January and February being the 13th and 14th months
of the previous year.
y = year (4 digits)
Weekday = d + n1 + n2 - n3 + n4 (mod 7)
where n1 = INT(2.6 * (m + 1))
n2 = INT(1.25 * y)
n3 = INT(y / 100)
n4 = INT(y / 400)
INT is "integer part of"
Output is read as follows:
0 - Saturday
1 - Sunday
2 - Monday
3 - Tuesday
4 - Wednesday
5 - Thursday
6 - Friday
Example: On what day was February 29, 1972
Solution: d = 29, m = 14, y = 1971
n1 = INT(2.6 * 15) = 39
n2 = INT(1.25 * 1971) = 2463
n3 = INT(1971 / 100) = 19
n4 = INT(1971 / 400) = 4
Weekday = 29 + 39 + 2463 - 19 + 4 (mod 7)
= 2516 (mod 7)
= 3
= Tuesday
Hope this helps.

Subject: Reading Mac floppies on a PC
Hello !
I've been sent recently two Mac 3.5'' floppies with experimental
data. I need to transfer them to a PC since I have no access to a Mac.
The data themselves are in binary format (i.e. unformatted Fortran output)
and only integer numbers included. I confirmed that by looking through the
program listing I was also sent.
I want to know if there's a public domain device driver that would
permit to read Mac floppies to a PC with a 3.5'' drive. I know this may be
possible because there's such a driver for reading Digital's RX50 floppies
on a AT.
I managed to get a program from a Trickle server that strips off the
128-byte header from Mac files providing you got them on a PC first !!.
Any help greatly appreciated,

COM1 and COM3 use IRQ4. COM2 and COM4 use IRQ3. ProComm can be set to
any of these four. If you can jumper the third COM port to look like COM4
then the modem will compete with the printer, not the mouse. That might
work better (gaps in the COM sequence are allowed). Or if the mouse can
work on COM2, you might swap the mouse and the printer. Hope this helps.

These comments demonstrate that there is some confusion about the V-series
parts that I will try to correct.
The V20 and V30 are faster, functional extensions of the 8088 and 8086
processors. The V40 and V50 processors consist of the V20 and V30
processors integrated with a family of peripherals so as to be functional
extensions of the 80188 and 80186 processors. The functional extensions
do include 8080 emulation in each case.
For several years the sale of the NEC V-series parts have been hindered by
a law suit brought against NEC by Intel who claimed microcode copyright
infringement by NEC. The courts have recently found, in NEC's favor, that
although microcode can be copyrighted, Intel DID NOT HAVE a valid
copyright on the 8086 microcode and even if they did, NEC DID NOT COPY the
microcode of the 8086.
NEC's microcode-less V33 serves a market that is somewhat similar to the
80286, but it is not compatible with the 80286. It is upward compatible
to the 8086 and it supports memory mapping but in a different manner than
does the 80286: it directly supports LIM spec 4.0 with internal hardware.
Benchmarks show the performance of the V33 to be higher than the 80386SX
at the same clock rate.
NEC's V70 and V80 are full 32-bit microprocessors with on-chip floating
point and on-chip MMU. The V80 also has an on-chip cache. The V60 is a
16-bit external bus version of this same architecture. The V60, V70 and
V80 each have 32 32-bit general purpose registers, they support a 4 G-byte
paged virtual address space. The V60 and V70 offer an emulation mode to
execute 8086 code but this is the closest these processors get to the
architecture of any Intel processor. In particular, the V60 is not
similar to the 80386 or in fact any processor manufactured by Intel. NEC
does not offer any processor compatible with Intel's 80286, 80386 or
80486.

it's name? One would think that with all the bitching that people do
about it there would be someone who might actually let the people who
build these things know about it. Apparently this hasn't happened yet.
If you feel it's a justifiable complaint, and that the manufacturers
should be informed about this dissension in the ranks, what would you feel
would be the best way to go about it? [I feel it's a justified complaint.

The new GRAPHICS.COM in DOS 4.0 supports the EGA. I didn't think
GRAPHICS.COM ever supported a LaserJet but maybe you have an emulation
mode that works on the printer, so I guess if the old one supported it so
should the new. You don't even have to install the entire 4.0 package
just to use the new GRAPHICS.COM, so I read recently (in PC Magazine, I
think).
For what it's worth, I use the commercial program Inset, which supports
the combination you have and it works like a charm.

Subject: Entering Data by Pointing
Is anyone aware of the availability of a graphics package which allows one
to enter data by simply pointing at rows (or columns, or matrices) of
numbers from an ASCII file?
What I have in mind is the following. I run large scientific computations
on a mainframe, which produce enormous quantities of numerical output.
Rather than writing graphics routines for the mainframe, I would like to
transfer the data in some kind of raw format (e.g., like a print-out) to
my PC, and then be able to look at them graphically.
I don't want to have to decide in advance which data I want to graph,
instead I want to do this interactively with the graphics package, using a
mouse or something. The package should be able to handle 'scientific' (vs.
business) graph types, particularly contour plots.
