equivalent of a 486DX2
Really? You couldn't just give the actual CPU?
All high level application computing is done on a Sparc LX class portable computer manufactured by RDI Computer Corporation. See Figure 2. Key components of this computer are a 50MHz MicroSparc CPU, 32 MB's of RAM, 970 MB's of hard disk space, and a 1024x768 active matrix LCD display. (For comparison, this processor is about equivalent to a 486DX2/66 using Spec ratings as a guide.) The laptop contains an optional Peripheral Expansion Unit which is equipped with two SBUS slots and space for additional hard disk drives. The two SBUS slots contain a Datacell color video digitizer and a Performance Computer Company quad serial port expansion unit. The laptop runs SunOS 4.1.x.
