There is almost no information on the make or the the serial number. All I
have is
the "series" PD1005. On the case, there is just "Compaq Deskpro".

Possible to take a picture and post to a binaries group somewhere so we
could look at it and maybe recognize it?
1998 Would most likely be the 2000/4000/6000 series. I think the EP/EN's
came out after that. Is it a mainboard with a single big slot in the
center where a riser board plugs in and has the ISA/PCI slots? Also you
can look on the system board for an part number or spare part number, both
are 6 digits a - and three more digits, sometimes the last three will have
letters and numbers like -B21. You can plug that in a search and usually
find a hit to a page that may list the model of the machine. Also if you
do find a spare part number, search for the "service quick reference guide"
in .pdf format and download and search for that part in it.
