The simh (and other common formats) use 32bit values to indicate tape record sizes and other info about a record or file mark. They don’t actually contain offset information. As such, the limit on size is the limit on space to contain the tape image.
From: Tim Shoppa Sent: Wednesday, January 24, 2018 3:54 PM Many common tape image tools as of two decades use 32-bit integers to carry offsets around and will be limited to 4Gigabyte tape image sizes. I don't think this is a fundamental limit to the tape image formats used by SIMH, just a common limitation of the tape image tools you might find from 20 years ago. Tim.

I was looking through the doc’s and it wasn’t obvious to me. Is there a size limit?
