ATT 6310

Hello all, I have found a AT&T 6310 PC box. Can anyone tell me anything about it? Is it 10 years old, yet? It is heavy enough I'd thought it had a large linear supply in it, but only a switcher ps! It was made in Italy by Olivetti, as mentioned on the 6300 thread. Opening the top reveals a AT type passive motherboard- the CPU, etc. is apparently on another one in another compartment below it, which I haven't gotten to yet. All the cards are 8 bits, except a Mouse Systems serial card which extends about 1/3 way into the "16 bit extension". There is another 2 port serial card and also a MIcrosoft Inport card with a mini-DIN connector. There is also a serial and printer port on the "hidden" CPU card, both DB-25, and a DB-9 connector for the keyboard. There is a volume control on the front, but haven't found the speaker, either. -Dave
