it needed for long-term survival. Nonetheless, it survived as an inspiration for future
workstations.
       Priced at less than $10,000, the elegant Nextstation came with a 25-MHz
68030 CPU, a 68882 FPU, 8 MB of RAM, and the first commercial magneto-optical
drive (256-MB capacity). It also had a built-in DSP (digital signal processor). The
programming language was object-oriented C, and the OS was a version of UNIX,
sugarcoated with a consistent GUI that rivaled Apple's.
       • NEC UltraLite
       Necks Ultralite is the portable that put subnotebook into the lexicon. Like
Radio Shack's TRS-80 Model 100, the UltraLite was a 4-pounder ahead of its time.
Unlike the Model 100, it was expensive (starting price, $2999), but it could run MS-
DOS. (The burden of running Windows wasn't yet thrust upon its shoulders.)
       Fans liked the 4.4-pound UltraLite for its trim size and portability, but it really
needed one of today's tiny hard drives. It used battery-backed DRAM (1 MB,
expandable to 2 MB) for storage, with ROM-based Traveling Software's LapLink to
move stored data to a desk top PC.
       Foreshadowing PCMCIA, the UltraLite had a socket that accepted credit-card-
size ROM cards holding popular applications like WordPerfect or Lotus 1-2-3, or a
battery-backed 256-KB RAM card.



      •Sun SparcStation 1
      It wasn't the first RISC workstation, nor even the first Sun system to use Sun's
new SPARC chip. But the SparcStation 1 set a new standard for price/performance,
churning out 12.5 MIPS at a starting price of only $8995 - about what you might
spend for a fully configured Macintosh. Sun sold lots of systems and made the words
SparcStation and workstation synonymous in many peoples minds.
      The SparcStation 1 also introduced S-Bus, Sun's proprietary 32-bit
synchronous bus, which ran at the same 20-MHz speed as the CPU.

       • IBMRS/6000
       Sometimes, when IBM decides to do something, it does it right. (Other times...
Well, remember the PC jr.?)The RS/6000 allowed IBM to enter the workstation
market. The RS/6000's RISK processor chip set (RIOS) racked up speed records and
introduced many to term suprscalar. But its price was more than competitive. IBM
pushed third-party software support, and as a result, many desktop publishing, CAD,
and scientific applications ported to the RS/6000, running under AIX, IBM's UNIX.
       A shrunken version of the multichip RS/6000 architecture serves as the basis
for the single-chip PowerPC, the non-x86-compatible processor with the best chance
of competing with Intel.

      •Apple Power Macintosh
          Not many companies have made the transition from CISC to RISK
    this well. The Power Macintosh represents Apple's well-planned and
