AAEON PCM-5894 5.25" CPU Board | Single-board Computer (SBC) | Supports Intel Pentium MMX/AMD K6-2/Cyrix/IBM/6X86MX-PR/IDT WinchipC6 with SSD, LAN, VGA/CRT, 4xCOM, 2xUSB, PC/104, L2 Cache, EIDE Simple Type: CPU Board

The PCM-5894 is a Pentium single board computer with one onboard PCI SVGA controller, one PCI Ethernet interface and one PCI expansion slot. Equipped with a 64-bits local bus architecture, the PCM-5894 releases Pentium's full potential and provides unprecedented performance compared to current 32-bit processor boards. The PCM-5894 offers all the functions of an industrial computer on a single board, but fits in the space of a 5¼" floppy drive (only 5.75" x 8"). For maximum performance, the PCM-5894 also supports a 512 KB. L2 cache onboard. An SSD interface supports one 32-pin DIP socket for the M-Systems DiskOnChip 2000 series, memory capacity from 2MB to 72MB. Onboard features include four serial ports (three RS-232 and one RS-232/422/485), one multi-mode parallel (ECP/EPP/SPP) port, one floppy drive controller and one keyboard/PS-2 mouse interface. The built-in high speed PCI IDE controller supports both PIO and bus master modes. Up to two IDE devices can be connected, including large hard disks, CD-ROM drives, tape backup drives, and other IDE devices. The PCM-5894 also features power management to minimize power consumption. It complies with the “Green Function” standard and supports three types of power saving features: Doze mode, Standby mode, and Suspend mode. In addition, the board’s watchdog timer can automatically reset the system or generate an interrupt in case the system stops due to a program bug or EMI. The PCM-5894 is a highly integrated, all-in-one single board computer. All onboard peripherals (including PCI flat panel/VGA interface, PCI Ethernet, and PCI IDE) adopt PCI technology and operate through an internal PCI bus. Integrating a Pentium board with a PCI architecture has unleashed a revolutionary level of performance. The PCM-5894 is one of the smallest and most powerful all-in-one Pentium boards available.
