I need some help from someone out there with a Philips P2000c computer.
I bought it new 3 years ago, and I've got a couple of difficulties.
 
First, I've got some power supply problems.  The system refuses totart with h
the power supply connector attached.  If I unhook the lines from the power 
supply to the computer (inside the case), it will start up OK after the power
supply is 'warmed up'.  Anyone got any ideas or a source for parts, schematics,
etc?
 
Second, I've never been able to get anything from the serial communications
port.  I can use the printer port, but the comm port doesn't seem to do
anything.  Does anyone know the pinouts, voltage levels, Z80 portsm etc. that
I need to use the port?

My mnachine also has a 8086 CoPower board with 512k of memory.  Does any one k




Sorry about the format of this article.  I'm sending it from a BBS at the U of
Arkansas, and we just got the ability to post articles.  There's no info any
where for us about using the editor!

Does anyone know what the latest version of the Terminal ROM and Preliminary 
bootstrap for MS-DOS on this machine is?  And if there has been an upgrade
since I bought mine, where can I get it?
 
Thanks in advance.
