Inside the Apple IIe

In response to my October 26, 2008 post, Rob said, “Am I correct in assuming that your Platinum //e came with a "SoftCard" or clone? Did it come with any other unique hardware like a clock? (for us old timers, clocks were a neat thing)”

The short answer is, “no.” The IIe came with a Super Serial Card, an 80-column 64k RAM card, and a floppy disk controller card (with two working half-height floppy drives.)

I did find an original Microsoft SoftCard at a garage sale. The seller warned me that it would not fit any modern computer and that I would need an older PC-XT or Versa Local Bus to use the card. I thanked him for the information, handed him my $5, and took the change. I set the switches, plugged it in, and it ran the flawlessly.

Along the way, I also picked up a parallel printer card that works well with a Brother laser printer in default Epson FX mode.

Therefore, the inside of the Apple IIe looks like this:
  • 0 — 80-column, 64k RAM card
  • 1 — Parallel Printer Card
  • 2 — Super Serial Card
  • 3 — (empty)
  • 4 — Microsoft SoftCard
  • 5 — (empty)
  • 6 — Floppy Drive Controller
  • 7 — MicroDrive IDE/CF Card
By default, the system boots into ProDOS on the MicroDrive. When I want to use CP/M, DOS 3.3, or Apple UCSD Pascal I put the disks in the floppy drives and reboot there.

I am still mucking around with DOS.MASTER and have yet to get it to work. Thankfully, the recent supply of 5.25” disks allows me to run the other systems until I either get DOS.MASTER to run right or give up on it entirely.
