We seem to have had a prototype interface which was evidently designed by someone with no access to DEC's documentation of their memories, it did not work correctly at all. FPS was at least helpful about fixing it, but it took a LONG time. On the Twenty, also, you dont gain that much performance without VERY careful coding of programs to run in the AP (their fortran wasn't nearly good enuf at reducing loading/unloading programs and data from the AP). On the other hand, one of the people here has an AP-120 on an 11 and he seems pretty satisfied. Mark -------
