- Well, first you upgrade it to a 512KE, then you go from there...
-
- Seriously, though...
- the major difference between a 512K and a 512KE is that the E has
- Mac Plus roms. The reason that this was done was so that you could
- use an 800K disk drive in the machine. The 512K used the original
- 64K roms which only supported 400K floppy drives (following this?)
-
- Any upgrade you are going to do is going to require new roms.
- You could buy a Mac Plus motherboard (and back half of the case)
- from some third party (i.e. Shreve, Pre-Owned Electronics, etc).
-
- There are other products available which will give you expandability
- in the form of simm slots (for up to 4 megs of ram) and a SCSI port,
- but these require that you have Mac Plus roms in your machine.
- They also require some amount of surgury.
-
- Also, if the machine was used a lot, the power supply may be
- frail...if you're going to do an upgrade, you might wind up
- replacing that power supply soon afterwards.
-
- You'd probably want a new floppy drive (800K) as well.
-
- When all is done, you could probably have bought a new machine
- for the same price. Save your sanity -- buy a new machine.
