Page "ARCNET" Paragraph 6

ARCNET was eventually standardized as ANSI ARCNET 878. 1.

It appears this was when the name changed from ARCnet to ARCNET.

Other companies entered the market, notably Standard Microsystems who produced systems based on a single VLSI chip, originally developed as custom LSI for Datapoint, but later made available by Standard Microsystems to other customers.

Datapoint eventually found itself in financial trouble and eventually moved into video conferencing and ( later ) custom programming in the embedded market.
