Pico Systems was making analog servo, stepper and digital servo products starting in 2002 for the original EMC program. Our products are organized a little differently that Mesa's, we have a board for each basic system type rather than reprogramming the board for what type of I/O you want.
Mesa's scheme is to sell the FPGA board at a VERY low price, but then you need a number of add-ons. We try to sell one unit that is as complete a controller as we can, at the best price we can still make a few dollars on. While we are not coming out with a new product every month, we tried to make a complete controller, and then provide a stable product. When computers got faster, it caused some issues with the connectivity between the PC and the controller board, and we had to make changes to keep that working. But, we've tried to make everything backward compatible. I know (due to occasional repairs and questions) that some of the controller boards we sold as far back as 2004 are still in use.
