MISCELLANEOUS TECHNICAL NOTES.

Note: The LEDs on CPU Card 1 and CPU Card2 are ‘overheat’ indicators. If any of these LEDs come on on either card, turn computer off as soon as possible to prevent damage. Note: If installing CPU card 1 only, insert the terminator card in CPU socket 2. Do not use CPU card 2 only
