I first met these "guys" in the mid-1980s at the monthly computer shows in the convention center in Marlborough, MA (on right side of rte 20 about a mile to the west of I-495.
It's a small group but they really know their stuff. On 12/23/21 my windows 10 box committed "suicide". I'm unsure of its cause but it may have been an electrical issue (dumb, general response). The following day (12/24) I took it to the store and asked if it were possible to get the machine on Saturday (12/26). No such luck it was Xmas weekend! Anyway, the store called me the following Monday afternoon. I picked up the box on Tuesday noon, 12/28. I needed a new motherboard, "C" drive, CPU; what the heck, they "gave" me a new box as some of the other parts in the old box (except two other dislk drives) were no longer available. I was very happy with their work as I have usually been. HOWEVER, it is almost RELIABLY impossible to restore all the software as it was before the crash. So, if you're reading Mr Softy, it took me about three weeks to restore everything.
I've referred the store to several friends and to a business where I worked about 15 yrs ago. All thought CTS did great work!
