Hitachi HD-200 PABX Telephone

NEVER:

• Never pull the MEMORY or CENTRAL PROCESSOR cards (the two cards on the lower left part of rack) out of the system. This wipes the memory. If you do be prepared to spend hours reprogramming.
• Never let the memory battery pack be discharged and turn off the system. If you do, be prepared to spend more long hours of reprogramming. Change the battery while under power only.
• Never give up. The HD-200 is a good system. It is always good practice to get a program print out before a failure.

The HD-200 was Hitachi's effort to produce a small, economy, non blocking PBX / PABX telephone system. The program resided in RAM and had to be manually programmed. Several thousand were produced in Japan and imported to the U.S. and sold nationally. This was during the tense Japanese/American trade relations of the Reagan Era. The system was discontinued due to political pressure, legal issues, and not to any technical flaw. I was there, and know the whole story. The system is now over 15 years old but with proper maintenance and a few spare circuit cards should last another 20+ years. The only real natural enemy is a bad thunderstorm.

The only cards that seem to be rare are the IOCNTA(SMDR) and MWUA(message waiting power supply). If you have any of these cards in stock we are always searching for them.
