╟─────────────────────────┐ Additional Info ┌───────────────────────────╢
║ ║
║ Due to Engineering Changes in the 7000, additional jumpers were ║
║ added (W98,99,100,200,201) increasing the board's flexibility. These ║
║ are marked with a (+). Newer models also added an LED and fuse for ║
║ term. power. ║
║ Software for the 7000 comes from Columbia Data Products, called ║
║ SST. The OEM version of the board is the 7000-ASC, and the consumer ║
║ version, with the SST software, is called 7000-FASST, or 7000-FASST2. ║
║ The Hardware design was sold to Future Domain Corp. in 1991. ║
