resided in RAM and so reduced the available program space. Typically single or double sided 40 track floppy drives could be supported. The power consumption of an expanded UK101 could require up to 5 Amps at 5.0Vdc (25 Watts), so heat dissipation and power supply de-coupling were common challenges. Compare with a modern ARM microcontroller with similar capability at 0.5 Watts.
