Post-Probe, 1st Ever Universal P.O.S.T. Card for All PCs!

I'm almost certain that most technicians these days are using P.O.S.T.
cards to solve problems in the dead P.C. and we here at Micro 2000 Inc.
are no exception. We were marketing our own "2000-1" card last year and it
was a good performer. Since that time we have had a great deal of
communication from the field and we have ken taking suggestions on how our
card and how the cards currently on the market could be improved. The
people with whom we consulted felt that cards in general were not specific
enough.

Most technicians and field engineers we talked to felt that it would be
better if they had a card that would take them down to chip level. They
needed a card that would allow them to gather more details and give a more
definitive answer to problem solving. So, keeping these things in mind we
put our engineers to work and this is what we came up with.

* We wanted to make our new card Universal. That is to say we wanted to be
able to solve problems on all P.C.s out there so we came up with the
"Micro 2000 Micro-Channel Adapter" so we could simply plug into any bus on
the market. The ISA bus will run on all the others including EISA and
Compact Machines. We then had to include the various port addresses and
that problem was solved.

* We then added voltage pads above four (+5vdc -5vdc +12vdc -12vdc) LEDS so
the actual power could be tested under load with the use of a voltmeter.

* We added four more LEDs to monitor Hi and Low clock and oscillator
signals. This made it easy to see if they were synchronous or not. They
are on separate circuits and this made it easier to spot the difference
between clock chip and crystal failures.

* We added two more LEDS to monitor I/O read and I/O write to distinguish
between read and write failures. We also monitor Memory Read/Write to
distinguish between address line failures and memory chip failures. This
feature also helps with systems without POST codes such as DTKs and XTs by
letting you see and follow the POST procedure.

* We monitor ALE for proper CPU/DMA operation as before.

* We added another LED to monitor Reset. This allows a reset to be seen
during POST and indicates a short.

* We then added a tri-state LOGIC PROBE to determine actual chip failures.
This is another unique feature in that any part of the board. cables and
the chips themselves can be tested.

* We have a very comprehensive manual. It covers POST Procedures for AMI,
AWARD. HEWLETT PACKARD, IBM, MR BIOS, PHOENIX and XTs and DTKs. It has
POST Codes covering AMI, AWARD, COMPAC, IBM, MR BIOS, PHOENIX AND
QUADTEL.

The manual is laid out in such a way that on the left side of the page
appear the POST Codes with what test failed next to it and on the facing
page aligning these data two further sections on 1. what would cause that
failure and 2. a Trouble-Shooting section that has any major chips, their
descriptions and the pin outs for these chips so that the user can then
make use of the LOGIC PROBE and test for actual chip failure.

* POST-PROBE has two Hexadecimal Displays that read out POST Codes as
described in the manual.
