The [https://www.advantech.com/products/todatasheet/D506B81F-3573-48AF-8F8A-DA57B0B22EBA PCM-9375 A3 specifications] shows these points that interest me: | |||
* AMD Geode LX800 500 MHz CPU (see the [https://www.amd.com/system/files/TechDocs/33234H_LX_databook.pdf AMD Geode LX Processors Data Book] for more information) | |||
* AMD Geode CS5536 chipset (see the [https://www.amd.com/system/files/TechDocs/33238G_cs5536_db.pdf AMD Geode CS5536 Companion Device Data Book] for more information) | |||
* Dual RTL8139 10/100 Mbps Fast Ethernet (second requires breakout board that I have) | |||
* 5V power supply (12V needed for optional LCD) | |||
* CompactFlash storage | |||
* 3 RS-232 serial interfaces (only the main serial interface is given a port) | |||
* 8 GPIO pins | |||
This at minimum would let me run by Internet-connected DOS bot and talk to DOS over a serial port. | |||
I've also not had an x86 board with GPIO before, so that seems like something fun to play with. | |||
Note that the IDE connector on the board is 2.0mm pitch, not the standard 2.54mm pitch most IDE cables use. | |||
TODO: Look at board again and validate and clarify these specifications. | |||

At least, until I saw an offer on eBay: a used [https://buy.advantech.net.au/Boards-Cards/Embedded-Single-Board-Computers-3-5-Single-Board-Computers-By-Processor-AMD-G-Series-Processor/model-PCM-9375F-J0A3.htm?country=Australia&token=637787139068984110&f=AUS Advantech PCM-9375F] for only $50 AUD, which is over $400 less than new. | At least, until I saw an offer on eBay: a used [https://buy.advantech.net.au/Boards-Cards/Embedded-Single-Board-Computers-3-5-Single-Board-Computers-By-Processor-AMD-G-Series-Processor/model-PCM-9375F-J0A3.htm?country=Australia&token=637787139068984110&f=AUS Advantech PCM-9375F] for only $50 AUD, which is over $400 less than new. | ||
Why such a huge discount? Video output is broken. Which means you can't really do much with this machine | Why such a huge discount? Video output is broken. Which means you can't really do much with this machine. | ||
