Space is always at a premium. Take the desktop, for example: No matter what kind of work you do, there never seems to be enough room. Our research of a cross-section of North American organizations found the space crunch is only going to intensify: 90 percent said workstation size will decrease or stay the same over the next 5 years.
While space is shrinking, so are central processing units (CPUs). But it's a business reality that organizations can't afford to adopt these new, smaller CPUs everywhere. The result is a squeeze: work areas getting smaller even while most CPUs are as clunky as ever.
A few running apps (Angry Birds, Safari, Infinity Blade, Flash cards), low CPU usage but lots of memory being used...ouch
The main PCB of the unit. It contains a Z80A CPU, Z80A-PIO (for the parallel interface), Z80A-DART (channel A for the RS232 interface, Channel B is switched between the current loop interface, cassette interface and internal strip printer), Z80A-CTC (baud rate clocks for the DART), 34K RAM, 30K ROM, the printer control microcontroller and glue logic.
