Will you get? buy the chip, its available now. Do you get?... read on.

The CG16 or NS32CG16V-10, -15 is a 68 pin plcc device that contains the
32C201 (TCU) and 32C016 (CPU) functionality on one chip. It is a CMOS device.
The instruction set is 100% (+/-) compatible with the rest of the 32000
series of CPUs. It does NOT have the MMU instructions, eg MOVUS etc and does
NOT connect to an MMU. It does HAVE extra instructions to assist in its
intended application, ie graphics. It has BITBLT instructions and some RLL
primitives. Think of the NS32CG16 as an embedded controller, ie its cheap,
around US$20 - 30 and requires the addition of a crystal, or module...  It
DOES interface to the 32081 or 32381 FPU, with the 32381 it DOES support the
new transcendental primitives.

I have built a simple CG16 board that runs at 15 Mhz, uses 4 256k x 4 bit
120 ns drams, a NS32CG821 (new version of DP8421), DUART, couple of gates,
buffers and latches and 2 256k bit eproms, and an e2rom. The total chip
count is 27 devices. It interfaces to one of National's demo ethernet
boards. It is basically a printer buffer, ie it takes either of the serial
uart channels, and or the ethernet channel, gives 512k bytes of buffer
and talks via it's the centronics port, to a laserjet II. Its getting
cold and miserable (silcon valley) now, so one has to do something in
the winter to keep busy.
