The serial number is "R 047012 40 83 RC1" and the model number is "PHC004A". You can find a picture of it at this URL: http://staff.motiv.co.uk/~kevan/old_collection/manufacturer-ti.html I have been searching for information about this machine for some time. I would like to know if it was a production version or some sort of custom job. Regards -- Kevan Kevan, If there is a serial number such as this, it was probably a limited-edition production version. I wouldn't envision it as a custom job. In fact it is probably worth lots of money, because it's the only one I've seen in my lifetime! Bryan bnicalek(a)aol.com
