SBCs
Single Board Computers
Para aplicaciones embebidas se pueden usar placas con procesadores que soportan Linux, y tienen todo incluido (usan flash como HDD).
Debería haber incluso alguna que se alimente del PCI y parezca una tarjeta de red, pero todavía no la he visto... :-/
- SBC82610 Via C3 Half-Size SBC Low Power (4W)
- Portwell PEB-9330l Samsumg ARM7 SBC con un consumo infoerior a 3W (16MB RAM, 2MB Flash).
- Arbor's PISA SBCs EDEN (PCI/ISA, unos 315EUR), ZFx86 (PCI/ISA, sólo 4.5W), Ali386SX (es ISA, lo pongo como referencia ya que consume sólo 3W), P III, K6, ...
Update 20200226: Hemos empezado a usar una arbor con AMD Geode LX800 (específicamente la Arbor Em104-a5362). Hay unformación sobre ese chip aquí:
Very unlikely you can overclock that at all. The Geode LX was an improved version of the old Cyrix MediaGX processor, first introduced in the mid-1990s. National Semiconductor rebranded the chip when it bought Cyrix, and later sold it to AMD, who sold the MediaGX as the Geode-GX, then later grafted on a DDR controller to the design and created the Geode-LX.
None of these chips was easy to overclock or particularly able to do so. They were also very slow, because they are based on 1995 CPU and graphics technology integrated into one package; the MediaGX was essentially the world's first "APU" ever made. The CPU section is based on the old Cyrix 5x86, and the graphics were just typical 1995 fare, 2D only.
Some motherboards that used these chips could be adjusted via DIP switches on the board for overclocking, but they're still really slow. I have an old Compaq laptop that runs on MediaGX-233, and it's so slow it can't even run Puppy Linux decently. Anything newer than Win98 crawls on it.
- Portwell PEB-6530VL Geode586-on-PCI
- Global American 3301141 PISA VIA EDEN
- JUKI-C3-1G/JUKI-EDEN-400 tarjetas combinadas PCI/ISA VIA con C3@1.Ghz y EDEN respectivamente (más)
- Tornado PCI/Standalone DSP en PCI que puede funcionar de manera autónoma. No parece tener S.O.
- JK microsystems's LogicFlex 386 en sbc, con DOS "preinstalado" (o al menos compatible con él; incluye web server)
