PC/II+d
L    Single-board PC/104 Computer


for Low Power Applications



Megatel’s PC/II+dL is a low-power PC/104 compliant single board computer with all of the features that made us famous. This board is available with a broad set of options that can be mixed in any combination to maximize price and performance. 

On-board options include: Intel DX4 processor, Super VGA & LCD panel output, Ethernet, up to 8MB of on-board flash, up to 32MB of Memory, up to 4 Serial ports and Parallel port, IDE and SCSI – all of which are packed into a small rugged package which you will find perfect for your low power applications which require RISC-core DX4 performance.

The PC/II+dL utilizes a local bus architecture for its peripherals, which maximizes the processing power of the 486 central processor without the normal speed limitations of the ISA Bus. This local bus design is provided for the VGA/LCD controller to ensure maximum speed and a price that can't be matched.
