Hey,

remember the bit about changing the Courier V.E so it can handle Caller ID?

I was bored last week to I took the modem apart (what other better reason is there?)

My motherboard has a daughterboard on it so it was of the type to be modded.

Had a look at my board and it is a Rev E so i went to the appropriate
section in the instructions which are:

----------------------

There are 2 different circuit board layouts for the USR motherboard.
The location that you will install this little circuit depends on
whether you have the REV "E" motherboard or an earlier one.  The REV
"E" motherboard is easy to spot because of the "REV E"
etched into the
board at the front corner, between the end of the volume control
slider, and the front panel push-switch.   Also, the REV "E" board has
the speaker located in the rear, near the serial port connector.   On
earlier boards, the speaker is located more towards the middle of the
board.

In either case, the R-C circuit needs to be installed so that it
jumpers 2 pins on one of the motherboard chips.   This is a small 6-pin
chip that is used as a solid-state hookswitch relay.   On the REV E
boards, the chip is an LH1500 or XCA111, and is designated U11.   On
earlier boards, the chip is an LH1056, and is designated U8.

In both cases, the chip is located near the DIP switch block.   Look
at the silk-screened lettering on the board, and you will see that all
the component locations are marked.   Just look for U8 or U11 as
needed, and make sure the part number stamped on top of the chip matches
the ones listed here.

------------------------------
Let me just say that I found the silkscreen for the chip (U8 I believe) but
there wasn't a chip there at all!!!!!!

Now I don't know what revision of modem I have. It IS Austel approved and
was bought here in OZ about 8 months ago. Has anyone delved into their
modem to have a look-see?

Does anyone know what's going on?
