AppleII

Specification

• Apple II+ (serial number not found) (+ cards, see below)

Origin

Donated by the University of Antwerp around 1993. The monitor is rumoured to have been their first computer display.

Done

The original full-height 5,25" drive got broken. I've replaced it by two (smaller) drives.

To Do

Try CP/M.

Expansion Cards

Following cards are installed:

• slot 0: 16KB RAM expansion "language card"

• slot 6: Disk II interface card

There are bunch of other, currently unused cards:

• D780C (Z80 clone)
• Disk II + Shugart
• Unidentified, has a 26 pin flat cable connector and only an EEPROM and 74LS ICs.
• Unidentified, TV modulator ?

Software

• Apple DOS 3.3 with various programs:
  • Visicalc
  • Games: Castle Wolfenstein
• Prodos 8 v1.9 with ADTpro
• CP/M with various programs (t.b.t)

Data Exchange

Using ADTPro over the audio/cassette port allows to transfer disk images (.DSK) to and from physical 5 1/4" floppies.

It takes about 20 minutes for a 180KB disk side, requires trial-and-error adjusting of mic and headphone volume on the PC side and good audio cables. Once it's set up it is fairly reliable.
