It was down all weekend. They came in this morning and decided to give it a try. Pulled out the PCMCIA card and gave it a shot of canned air and put the card back in. They plugged it back in and it booted right up this morning. Hopefully it will stay running. The unit looks Just like a Call Pilot 150 for a Norstar. The Nortel part number is NNTMN1006HVC NTAB9825. I don't have a picture of the PCMCIA card or the part number for it.
