 machine by now

- * Tape driver ALWAYS uses "Alternate Boot Device", which is assumed to ALWAYS
- * be the boot device in pagezero (meaning we booted from it).
- *
- * NOTE about skipping file, below:  It's assumed that a read gets 2k (a page).
- * This is done because, even though the cartridge tape has record sizes of 1k,
- * and an EOF takes one record, reads through the IODC must be in 2k chunks,
- * and must start on a 2k-byte boundary.  This means that ANY TAPE FILE TO BE
- * SKIPPED OVER IS GOING TO HAVE TO BE AN ODD NUMBER OF 1 KBYTE RECORDS so the
- * read of the subsequent file can start on a 2k boundary.  If a real error
- * occurs, the record count is reset below, so this isn't a problem.
