Replacing or substituting parts can be a challenge. Often the manufacturer either used of the shelf parts (in which case this is unnecessary), or used their own one of a kind or "specialized" parts. Wherever possible, remember somethings are electronically different, and some are wired differently. Identify why the part is different (1) Most often manufacturers simply had items wired a little different so you had to go to them for the part. Electronically the item is no different, but simply had a different pinout. In this case, check for pinouts, and create your own cable or gender changer to use more common parts. (2) Physical size can be a challenge, if it was smaller, most new equipment has become smaller and should avoid this issue. If it was a larger part, you may find yourself making drive rails or mounting brackets for the newer part. (3) I think all of us collectors and nostalgia computer geeks, like to put it back to as close of an original status as possible. But, you have to draw the line somewhere. Do you really need the $600 light pen to draw, or can you use the original mouse. (4) Is the part really necessary, or is it for flare? I would love to supercharge my Amiga 1200 to the latest PowerPC, but why would I spend +$500, to do the same as a $200 AMD powered IBM compatible with the latest Amiga emulator.
