1.5-m Telescope Drive Interface Upgraded (1Dec95) (from CTIO, NOAO Newsletter No. 44, December 1995) The definitive version of the electronics that interface the drives at the 1.5-m telescope to its control computer were successfully installed during an engineering run in August. This new PCB based version replaces the handwired prototype that has been in service for two years. This change is invisible to the user but it was greeted with a big sigh of relief from those who must keep the telescope running. Although the prototype has given trouble free service, we have, until now, been completely without spares for this vital piece of the 1.5-m control system. Those responsible for the successful completion of this project were Rolando Rogers, Ramon Galvez, Javier Rojas and David Rojas. Steve Heathcote
