 TRS80 Model 4/4P
 (or right now more accurately sdltrs/xtrs)
 
-Emulator Bugs:
-       The emulator is horribly insecure, it's default is to allow all
-       sorts of direct access to things. Even if you turn this off I've
-       had it segfault with FUZIX bugs which suggests its not too secure.
+Requres:
+       Patched xtrs from Fuzix git tree
 
+Emulator Bugs:
        Repeating instructions like LDIR appear to be misemulated. LDIR
        is performed an emulated block copy, not as an iterated LDI. The
        real processor actually implements LDIR as  "LDI, if not done
        PC -= 2". FUZIX doesn't do any overlapped LDIR tricks so shouldn't
        be affected.
 
-       The interrupt flags are misemulated. A patch for this is in the
-       Fuzix tree and is needed to run Fuzix on xtrs/sdltrs
+       Other bugs in RETI, IFF handling etc have been fixed in my xtrs
+       tree.
