Andy, of course, that board design is about 25 to 30 years old. I have several of them since Olim's time, i.e., DOS 3.3 ages. The SMC 800 (as well as the naked SMC1500) can be run with the drivers that EMIS delivered with the board. At those times, every user had to write his own stepper software, and a ready made driver including trajectory planning was highly welcome. The C and PASCAL drivers include the features of ramping and drive the 3 axes simultaneously, also on the SMC 800! The piggy back board on the SMC 1500 is only needed when you are not using these drivers and write your own software. The drivers can still be downloaded from EMIS as well as MS-Windows software.
As the boards are apparently undestroyable, they still are in use around the country and they still sell them today although the design is not quite up to date. I once killed a transistor array by thermics and had to replace it, that was all.
