PCM-4335 Manual (689KB)
PCM-4335 Drivers (2.91MB)

If your application demands small size, PC compatibility, with 486DX-66 processing power, flat panel VGA/LCD support, and PC/104 connections, then the PCM-4335 single board computer is right for you.

The PCM-4335 features an ISA (PC/104) 16-bit data bus, with 32-bit processing ability. It can accommodate up to 128 MB of RAM, two IDE hard disk drives, and up to 72MB of DiskOnChip®.

The PCM-4335 has one RS-232 serial ports using a 16C550 UART, and accommodates 16 byte FIFO transfer with speeds up to 115Kbps.

The PCM-4335 has an ISA-bus flat panel VGA interface using the C&T 69000 chipset, offering 2MB of on-board DRAM, and supports both CRT and Flat Panel (TFT, DSTN, MONO and EL) displays.
