This was taken at a local Bob’s Stores when the day after the New England Patriots won their fifth Super Bowl. (Roger That! Heh, heh, heh.) For this chain, ROLM is alive and well, to use the cliche. Because ROLM predates the Internet and modern day documentation, I have no idea what type of PBX or KSU it lives on. The set themselves is the 1990s generation, before they became German looking (possibly mid 1990s.) When ROLM was fully sold to Siemens, a few years later, they stopped selling their systems to America and incorporated ROLM features and their modernest designs. I’m not the expert in ROLM so forgive me.
