I have a board with an AMD Geode CPU for some light retrocomputing development. This page details it and whatever I get up to with it. | I have a board with an AMD Geode CPU for some light retrocomputing development. This page details it and whatever I get up to with it. | ||
== Board specifications == | |||
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 (you don't see x86 boards with GPIO often) | |||
*No [[nopl]] instruction support | |||
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. | |||
