The Jupiter uses a Analog Devices 16 bit processor. The following is from
AD's site:

16-bit, 40 MIPS, 5v, 2 Serial Ports, Host Port, 80 KB RAM
General Description
The ADSP-2181 is a single-chip microcomputer optimized for digital signal
processing (DSP) and other high speed numeric processing applications. ADI
recently disclosed plans for a new ADSP-219x series. With speeds beyond
300MIPS, this new series is ADSP-218x code-compatible.
The ADSP-2181 combines the ADSP-2100 family base architecture (three
computational units, data address generators and a program sequencer) with
two serial ports, a 16-bit internal DMA port, a byte DMA port, a
programmable timer, Flag I/O, extensive interrupt capabilities, and on-chip
program and data memory.
The ADSP-2181 integrates 80K bytes of on-chip memory configured as 16K
words (24-bit) of program RAM, and 16K words (16-bit) of data RAM.
Power-down circuitry is also provided to meet the low power needs of
battery operated portable equipment. The ADSP-2181 is available in 128-pin
TQFP and 128- pin PQFP packages

I hope the answer to this question isn't too obvious: I've been looking
at the specs and write-ups about the Orion and Jupiter. I see a lot about
the Orion's dual 32 bit DSP processors but have not been able to find
anything about what the Jupiter's DSP processor is. Can anyone with a
Jupiter/Peg out there answer this?
Tnx & 73,
