Can someone tell me whether or not 80387-16's will work when placed in the inner pin sockets of the Wietek (sp?) math co-processor socket on early Tandy 4000's. I have had a hard time getting straight answers to this question. My dealer says that other similar sockets on other motherboards do that, but my 4000 owner's guide refers only to the 80287 and Wietek 1167 (again, I do not have the manual in front of me so please excuse mispelling or wrong chip number). However, it is my understanding that though they originally intended to support the Wietek chip, its cost was so great, Tandy gave up on that idea. They do list an 80387-16 in the latest catalog, but my dealer seems to think that early 4000's did not work with 80387's. I am very confused. Does anybody know what the story is for placing an 80387 on a Tandy 4000? Were early machines not supporting them, and if so, when and what did they do to start supporting them, and can the earlier machines be made to support them? They may have supported them all along. My dealer suggested I get one and try, but I hate to risk $350 and have it fail and possibly damage the chip. I would really appreciate hearing from anyone who has knowledge of this. Please email replies. Thank you, Mark. -- Mark J. Bailey, N4XHX "Ya'll com bak naw, ya hear!"
