Summary MESS-specific 08111: dn3500 and clones: Apollo machines cannot load programs from tape
Description All Apollo machines hang forever when trying to load a program from tape, which makes it impossible to install the OS. This seems to be a regression, since versions before 0.234 worked fine.

This also seems to prevent the OS from booting from HDD in newer versions once installed.
Steps To Reproduce - Delete the dn3500 CFG and NVRAM files so the machine is in the default state
- Run "mame dn3500 -ctape domainos" (needs the "domainos" set from the software list)
- When the machine starts, press ENTER a few times until the "MD7C REV 8.00..." message appears
- Run the command DI C
- Run the command EX CONFIG
- Wait approximately 7 minutes for the tape to load (can be fast-forwarded)

On versions 0.233 and older, the configuration program appears (see screenshot for what it should look like)

On versions 0.234 and newer, the machine never finishes loading the program.

That commit I've ID'd as the killer, as near as I can tell, from daily build testing.
