Hi everybody,

A friend of mine is having trouble with his COMPAC Deskpro 33 and he
asked me to send the following message:

---

I own a Compac Desqpro33, main board assembly No. 001184 which is defective.
I have traced the problem to an inability to access the DMA register and seems
to be linked to the PAL at position U28. Does anybody have a technical
reference manual for this board? The part number for the manual is 130 767 001. 
I have tried to buy it from Compac but they do not ship to Canada. If somebody
has the manual, please can you give me the logic map of the PAL if it is
published? If not, please can you give me the signals going in and out, that is
what is it linked to? Thanks a lot. Christopher

Thanks very much in advance for any info, Franky
