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).
