I have aquired an old IBM JX (or jr) pc, and being a mac user know next to
nothing about it (though I find it extremely interesting). I'm aware of the
hardware configuration, 8088 etc. What I'd like to know is are these beasts
compatible with the XT series, what about memory expansions(256k currently),
and what about the expansion slots - XT compatible? or JX specific, what can
I insert in these slots? What about the BIOS? questions, questions......

I've heard the memory can be expanded to 512k ( HOW? ) - I've opened the cpu
and there are 2 expansion slots for memory. At the moment there is a 64k card
and a 128k card. I assume the remaining 64k is in system memory. Someone        mentioned 'EMS' boards, what are these boards, where can I find one? How can I
upgrade the BIOS?  AAAAAAAARRRRRRRRRRRRGGGGGGGGGGGGHHHHHHHHHHHHH!!!!!!!!!!!!

Anyway, I'd appreciate as much information as possible regarding any or all of
the above questions. One option is to rip out the internals and replace the     entire motherboard and so on, but I found I like this machine in a quirky sort
of way, memory limitations and all. I really don't need another "power PC", I
already have a macII. I would like to add a MIDI card if possible though.

Please e-mail any reponses whatsoever to me, absurd and all, I'll even take a   flame for being a mac user with a smile (maybe!).
