Hi These usually are not very complicated. I have one of these from AMD. You might hunt around by using the search engine on the Intel site. I found quite a bit of information for mine by doing that with the AMD site. Mine has some flash and RAM with a few I/O's. I've put a simple Forth on mine that was adapted thing about these is the resetting of the special registers. These you can understand by looking at the data books for the C186/C188 version you have. These registers are slightly differnt for each letter version so make sure you are looking at the same one. The AMD had a special monitor on board to upgrade the flash. I'd suspect that the Intel board might be the same. If you should fiddle with the flash, make sure and save a copy. I found some information on an upgrade for the monitor but it required having the previous monitor loaded. Mine was an even earlier version. I did some fiddle faddle by loading the monitor at another location, as an application program and then using that to upgrade to the current version. It was tricky but it did work :) It now still has the monitor and the Forth as one of the applications. Dwight
