I was reading through the technical data for the V20 when I noticed the following under the section on the Queue Status signals: The CPU uses these signals to allow external devices, such as the floating-point arithmetic processor chip, (uPD72091) to monitor the status of the internal CPU instruction queue. I assume the uPD72091 is to a V20/V30 what an 8087 is to an 8088/8086, but I had never heard it mentioned in any discussion of the V20. Is this chip as compatable with an 8087 as the V20 is with the 8088 (i.e. a direct replacement)? If so, does it offer any advantages over the Intel chip? If both of the above are true, does anybody know of a supplier/cost? Thanks in advance... -- Name: John Ruschmeyer US Mail: Monmouth College, W.
