At least the Vic-20 and C64 can be crashed by a bad tape. I would expect 
the routines to be based on the PET ones, because during SAVE you can 
observe a similar amount of jitter in the signal. The tape routines on 
the 264 series (C16 and plus/4) are substantially different, and so is 
the tape format and even the connector.

My C2N232 might be one more option, if you can find one second-hand.  
However, it relies on RS-232, which nowadays is mostly available via an 
unreliable USB converter. The c2nload utility would load a minimum-size 
loader (192 bytes tape header + 2 bytes payload to jump into the tape 
header) and then use that to load the actual payload at 38,400bps.
