HP LogicDart CPU?
I've slowly been fixing inaccuracies and other problems in the Wikipedia HP Saturn article before I completely overhaul it ( although I haven't had much free time as of late to dedicate to HP calculator related activities ). In this regard, I wanted to add a reference to a reliable source that the HP ( and later Agilent ) "LogicDart" hand-held logic analyzer used a Saturn CPU/SoC. But, after some in-depth googling, I came across this forum post, which I'll post, Google machine translated from French, below :

Quote:Coming from the calculators part, we find a screen derived from that of the HP 48 but with more contrast (same definition: 131 x 64-pixel, but without the line of indicators and therefore with 10% higher pixels). There is also the possibility of infrared printing on a portable HP 82240B printer.

On the other hand it does not use the Saturn processor of the HP-48, nor the RPL for the software. The LogicDart processor is an Intel 80L188EB controller, integrating a low power x86 core, two UARTs, 2 I / O ports, 3 timers and other peripherals… The software was developed with the C Executive real time system from JMI Software.

The above seems to indicate that the LogicDart did *not* use a Saturn CPU/SoC, but instead an Intel x86-based microcontroller.

I always thought that the LogicDart used a Saturn CPU/SoC and ran an RPL OS due to its menu system being similar to the HP48 and the LCD display also being very similar with the same resolution IIRC.

I don't suppose that anyone has a LogicDart lying around somewhere which they could open up and confirm that the main CPU/SoC is Intel-based and not Saturn-based by reading the silk-screened chip package ID code(s)? Smile

Jonathan
