<p>UNIX floating point on the /34</p> <p><b>New page</b></p><div>==UNIX floating point on the /34==<br /> <br /> From Doug Gwyn from [https://groups.google.com/g/net.unix/c/-H9x36DMOBQ/m/4mcL76lKbmMJ?pli=1 here] (Jan 13, 1984):<br /> <br /> : ''It was fairly easy to take the 6th Edition UNIX 11/45 floating-point processor (FP11) support and add it into the 11/40 version for a PDP-11/34. One subtle problem with using the 11/40 kernel on an 11/34 is that the faulted-instruction restart code was not entirely correct for the 11/34, although later the 11/23 was again 11/40-compatible in this regard. The 6th Edition UNIX floating-point support also had some bugs that needed to be fixed if one was going to make heavy use of floating-point on an 11/34 or 11/23''<br /> <br /> [[User:Jnc|Jnc]] ([[User talk:Jnc|talk]]) 17:16, 7 March 2023 (CET)</div>
