Open and Accessible

For the most part this system is a standard configureation. The big difference is that it includes an SEBHC developed I/O board the provides two serial ports and a USB adapter that makes the computer appear to be a USB device when connected to a PC.

The system is fully operational. I use it to test software utilities designed to facilitate the USB-PC link. For example, there is device driver that lets the H89 use images of 5-1/4" floppy devices stored on the PC as though they are physical floppy disks, only at much, much faster data rates.

The snapshots show this system next to its companion PC (running Linux) and an internal view of the Serial/USB adapter board.
