  It's tax refund time and I am thinking of upgrading my PC7300.
I am wondering about doing the work myself and am polling the 
net for sagacious advice.

1) Has anyone out there done their own memory upgrade either on
   the motherboard or the 500k RAM card?
       It seems as if one could just cut out the old chips,
   carefully remove the legs, etc, etc...
   What I really worry about, though, is that some resistor or
   capacitor value would have to be changed, or some point-to-point
   wiring change would be necessary and I wouldn't know it.
   Anyone know anything about this?

2) What half-height 40M hard disks are spacially and electrically plug
   compatible?
      I would like to just "drop" a new disk in place. How about
    the new Seagate 251 drives? Anyone have experience with these?

3) If I just increase the memory, will I find more disk space used
   as swap space, or is the usage unrelated to real memory?

Finally, if I don't do it myself,
4) What are the current prices for upgrades from places such as
   Amperfax Corp?

Thanks (optimistically) in advance for any and all info.
