We have several AT&T 6386E (Olivetti M380) floor-stand computers. Two questions: 1) Is it possible to access the front display to use it for our own status messages? If so, how? 2) The card that drives this display plugs into the front-most slot. I asked the hotline if that slot can be used for regular cards instead (we can always use extra slots). He said that the slot is listed as a "modified 16-bit slot" but he did not know what that meant. Does anyone know if this slot can be used for normal boards? Thank you...

To do this, you'd need to write a unix or MSDOS device driver for the approprate environment. The pertinent hardware information you'd need to write the driver is in the "6386E WGS TECHNICAL REFERENCE MANUAL." This document is orderable from CIC (Customer Information Center) at 1-800-432-6600. Cost is about $150, and they take plastic. One of my cohorts says though that once you dig through the info, that you find out that it can only display 16 canned messages (ie, there's no way to send it an arbitrary string). Basically it involves putting a byte into an I/O register (the pointer to the message) and it displays that particular message that's been burned into the ROM. Also, writing device drivers is not a good place to learn C. You should be pretty C and Unix knowledgeable before you attempt to write one. >2) The card that drives this display plugs into the front-most > slot.

My guess (and this is strictly a guess) is that it looks like an AT slot with a few extra fingers. I just tried our disk controller in it, and it was atleast able to boot Unix. Keep in mind that when you remove the console card though you lose all the front panel features except for the power switch. The reset switch, speaker, speaker volume control, and key lock all run through the console card.
