You don't need an external 5.25" drive.  The PC Transporter
supports the concept of "disk images," specifically "hard drive
volumes" or files that represent the C and D drives.  You can
trade disk images with other PCT users OR you can set up
your own hard drive volume (a hard drive disk image set up
as the C drive), then null modem things from your real PC
to your IIe and copy them to your hard drive volume/disk
image file with the PCT utilities.

Kind of turns the whole emulator/disk image thing on its head,
doesn't it?  ;-)  Where do you think Randy Spurlock, the
programmer who started the A2 emulator craze, got his idea
for disk images FROM?

Right click on the following file to download the PCT
software.

This is the Apple High Speed SCSI card.  It lets the Apple II
run SCSI devices of all types (I, II, ultra, wide, whatever).

I have a 1GB drive running off it.  It supports DMA.

That's most likely a CP/M card.  Redundant because the
V30 on the PCT can also run in Z80 emulation with the
right software and run CP/M programs if you find the right
MS-DOS program to switch it into CP/M mode.

256 bits per chip, 256k per 8 chips, 1MB in 32 chips.  Note
that Applied Engineering's IIe RamFactor actually supported
5MB of total memory with the correct expander (the one that
actually shipped).
