The program descriptions and source code can be found in Methods in Enzymology (1988) 157, 378-417. The programs were originally written for the IBM-PC class of machines and require a 80x87 math co-processor. Dr. Fabiato will send the source and compiled programs on request, but there may be some delay. Perhaps they could be posted to an ftp-able site.
