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.
In case you were wondering, those Xeons are really, really huge. Like big enough to break your foot if you drop one on it, seriously. So big I wasn't able to put the system into another casemod I wanted to do. Darn it.
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.
