Kuper2001 users will be able to use joystick devices designed for RTMC48 systems without any modification.

IMPORTANT NOTICE ABOUT RTMC48 CARDS!  UPDATE.

We recently posted a warning announcement that certain failure conditions on RTMC48 cards could lead to widespread damage.  More recent events have revealed that the suspected problem is the result of incorrectly made cables at one specific user location.  If you are among the very small number of users who have PGHI chips damaged by external wiring, we no longer recommend that you replace or remove the damaged chips. Please call us (Tel: 310-414-0717) Regarding how to proceed with this matter..
