Commodore CSG == ICS??

I saw a news clip this morning about IDT (a semiconductor company) buying Integrated Circuit Systems. ICS makes analog and mixed signal chips and owns Turtle Beach Sound. The thing that made me curious was that ICS was located in Norristown, PA. I thought to myself what are the chances of there being two semiconductor plants in Norristown PA. The first successor to Commodore CSG, GMT Microelectronics was also into mixed signal ASICs. ICS is located at 2435 Boulevard of the Generals, Norristown, PA 19403. The Commodore CSG was located at 950 Rittenhouse Road. So, I ran a Mapquest on both addresses and it appears they point to the same physical location in the Valley Forge Corporate Center at the corner of Rittenhouse Road and Van Buren. Hmmm... According to the public filings, ICS bought the property in 1992, which was before Commodore failed in 1994. And, it's known that GMT Microelectronics (now defunct; owned by former CSG engineers and managers) bought the old CSG plant in 1996. So, it can't be the same location...maybe there are two semicon plants next door to each other?? Interestingly the president and CEO, Hock Tan, joined ICS in 1994. ICS was incorporated in Pennsylvania in 1976. Prior to joining ICS, Hock Tan was Vice President of Finance of Commodore International, Ltd. So, I emailed a contact at the Company, but I haven't heard back yet. Does anyone on the list live near Norristown, PA? It's about a 3 hour hike from me, so it's not that easy for me to visit. Rich
