ACU-SIGN Cardex by Acu-Bytes Inc. was another great DOS based database from the 90’s.
I have helped develop modern replacement applications as running ACU-SIGN on modern PCs have proven to be problematic and have successfully migrated my clients’ existing data so they can simply take off from where they left.

So if, you are looking to modernize you old Cardex database, give me a call and it will be my pleasure to help.
