Ports
- 1x ISA 8-bit (2.54mm-pitch pin header)
- 1x ISA 16-bit (2.54mm-pitch pin header)
- 1x Parallel (2.54mm-pitch pin header, break-out included)
- 1x RS-232 (2.54mm-pitch pin header, break-out included)
- 1x IO port (2.54mm-pitch pin header, break-out included) - VGA, PS/2 Keyboard & Mouse

Maintenance history
- Electrolytic capacitor closest to 12V input failed; vendor sent replacement, installed.
Faults
- RTC fails to keep time and CMOS memory when main power is off
- Machine struggles to remain powered when battery low
- Speakers too loud; amp draws too much power
- Windows 95 drops to 16-colour mode when Internet Explorer is running
