IBM's Federal Systems Division demonstrated a working model of a
preciously unannounced version of the company's best-selling PC -- an
RFI/EMI-resistant model reconfigured to meet TEMPEST specifications --
at this year's Association of Old Crows annual meeting in Virginia
Beach, Va.  The new machine is identical to the low-end consumer model
PC exvept it meets NACSIM specification 5100A.  Although the machine
had not been formally announced, IBM booth personnel at AOC said they
are ready to take orders.  Price is at least $6,975, twice that of a
conventional PC; delivery is quoted at 30 days after receipt of order.

The 16-bit computer is produced by IBM Entry Systems Division, Boca
Raton, Fl., and shipped intact to Federal Systems Decision's facility
in Gaithersburg, Md., where a special RFI/EMI enclosure and shielded
cables are attached.  Fiber optic cabling was considered, but
rejected.  Marketing is limited to government agencies through FSD's
natinal federal marketing managers in Gaithersburg or through IBM FSD
representatives.  Booth personnel said evaluation units had been sent
to unnamed government agencies (probably including NSA), but no orders
had been received.  The TEMPEST model PC is not on the GSA catalog at
IBM's request, they added, but officials said they expected it to be
on NSA's next preferred product list.

The heart of the computer is five cards: two for asynchronous data
transmission (including one for a serial printer, although IBM is not
offering such a printer), one for system network
architecture/synchronous data line control (SNA/SDLC), one for the
monochromatic-only display, and one to control the floppy disk drives.
The computer contains 192K bytes of RAM expandable to 256K bytes, and
runs on all IBM PC software, according to booth personnel.  This PC is
smaller than the enhanced versions of the IBM PC announced in October,
and is likely aimed at applications in local area networks (LANs) tied
in to large mainframe computers to handel highly classified data.
