Someone mentioned that he had built his own ramcard for the HP... 
would that person mind explaining how this is done & approx total cost?
A lowly college student wants to stick to his budget...

A little off the subject:

The 41C(V/X) could also do this: setting the appropriate flag would
make the calculator start running the current program when turned on.
So, setting the flag and runing a program with an infinite loop
containing the "off" instruction would turn off the calculator when it
was turned on. However, to be even nastier, by setting the modes so
that all the annunciators were off, and storing a string consisting of
a single blank in the X register, turning on the calculator has no
visible effect at all.

I think it is a matter of power consumption. Low power CMOS ram of some sort
must be used. With the constant memory of the new calculators, I would
suspect that static RAM is used, although I have no information on this.
Static RAM is still expensive. I looked into upgrading my cache on my
486, and it cost about $65/256K. This was high speed SRAM (for 33MHZ), and
it is rather expensive. Low power SRAM is probably in roughly the same
ballpark as far as price goes.

I wonder how long that 1MEG SIMM would last on a set of calculator batteries?
Where did I leave the databook...

Looks like a Hitachi HB46A18 series 1MB SIMM draws about 1.4W while
operating, and 20mW standby. It's probably much faster than needed for
a calculator, the slowest version offered is 150nS. Minimum Vcc is
4.5V, it might work at calculator voltages.  Looks like operating
current is around 280mA. AA batteries have about 1000mAhour capacity,
AAA is probably less. But assuming 1000mAH, and that the caculators
current requirement is much less than this (and is not a major factor)
it looks like 1000mAH/280mH = 3 Hours 34 min. Reminds me of the old
LED calcuators. If it was mostly in standby mode, you would get 50 Hours.
But I would guess that here the calculator will draw about as much
current, so say 25 Hours. So roughly between 3.5-25 hours operation.
Modern CMOS SIMMs are pretty impressive. But this is still a bit short
of modern expectations for calculator life.

OK, I've rambled long enough, back to doing what I should be doing...

Couldnt one look at the TICKS of their machine? Doesn't every machine
have a different TICKS? (Or the likelyhood of a machine having the
same number be very low?) Then you find the time and offset the TICKS
by the change in time. If its the same machine then TICKS-TIME OFFSET
should alway be the same. You could determine the TIME OFFSET by looking
at the clock each time you run this particular program and comparing it
to the number of ticks that have occured since the last time. 


Perhaps I am totally off base.. but its just a thought...

It all depends on how you want to do it, and what type of equations you are
dealing with.  If you want to do it numerically, there are programs available
at various ftp sites to do just that.  If you want to do them symbollicaly, you
will have to know what you are doing, but there are things you can do to 
simplify the task.  It has been a while since I had to do any DE work, and I
was using a 28s to do it, but it would be even easier on the 48. (Assuming you
are working on fairly simple or straighforward equations - but the coupled DE 
questions makes me think you aren't....) If you are interested, write to me and
I'll try to remember how I used to do it ;).

I have connected an old DMP200 matrix printer to my MSDOS machine, and I am using WordPerfect to print out some texts. The ASCII table in the printers ROM
is not conform the standard. This causes trouble when printing lines and 
special characters. I called wordperfect about this problem and found out 
they do not support this printer. Nearest emulation is the standard printer.

I have already converted the driver for the standard printer to the DPM200
halfway. However I am looking for someone who has the complete driver, 
and not only for wordperfect. The DMP200 can do a lot with graphics I think.
In its time it was a very expensive printer someone told me.

When filePro+ came out about 1984/85 - that was when it stopped being
Tandy exclusive.

And yes there are MANY versions available - and they go from $99 for a
DOS 3.0 to $40,000 for a 256 user VMS system.   DOS network versions
are also available.    Version 4.1 is really pretty fantastic.  I've
been through them all - starting with Profile on a Model I - which only
had the same name as the later Profile.  The first version wasn't even
from the same company.   Tandy released 3 database managers in the late
70s.  One was Profile, one was Versafile, and I forgot the name of the
other.   Pricing was something like $49, $79 and $99   - boy how times
have changed - and for the better.

The pinout is the same as any standard CGA card. And it's *digital*, not

Does the TRS80 have an RS-22 port (25 pin socket?)  If so, any standard
external modem should work.  If not, you need to specify what kind of TRS80
you have (Model I, III, 4, CoCo, 100, 1000, 2000, Pocket Computer?, etc.)
