AVR-Chat

Well all the rooms in the house now have dual cat 5 cables wired to a
central patch panel in the roof (crawl space for the Americans), The
Phone system is up there too (an NEC NEAX D3 or Telstra System 120 as
the AU people know them) The servers are all up there now too :o)

I am having a bitch of a time with the PABX, the TWO wire circuits work,
but the 4 wire ones are not behaving. Not sure if it is a blown card
(eith CPU, FPU, Motherboard or line daughter card or all of the above)
or a programming error :o( 

Tomorrow I will replace the CPU as I have tried at least 3 Motherboards,
Daughter boards and FPU's with no joy (this system was second hand, and
I have no idea why it was pulled out, if it works etc, it was free so it
came with a driveway warranty (IE once I left his driveway the warranty
had expired ;o)

Once this is all running, I plan to build an ISA card with some AVR's on
it to monitor the temp around the roof and in the equipment :o) was
going to do it through a serial port, but I think this way has more
appeal as I will then get experience writing drivers for a UNIX device
:o) (it will be memory access so should not be tooo hard (thinking of
using a dual port ram as the interface between the AVR and the IO bus or
just the AVR straight (any pointers ?)

I must have a lot of time on my hands to be subjecting myself to this
lol

Will post pikkies on my website once it is all finished and tided up (I
have piles of scrap cable littering the roof right now)


Regards,

Kat.
