Then again, SIMH supports limiting the emulated tape size.  The SIMH VAX document shows that it uses this feature: the tape units can be set to a specific size limit, or 0 for unlimited.  The same is true for various other emulations; I see the PDP11 has the same sort of thing, and for example its TMSCP controller defaults to 98 MB (TK50 size).
