Hello,
In what ways is the 4145B an upgrade from the 4145A? The B seems to sell
for quite a bit more money. But, a quick look at the manual
specifications seems to indicate they have similar capabilities. I
understand the floppy drive was changed? Anything else? Are there
digital upgrades to the B unit?
The "A" version uses a 5.25" diskette drive. The boot diskette is hard sector
with a weird format that I've not been able to copy.
The "B" version uses a standard 3.5" soft sector diskette. It has a weird
format - but it's capable of being copied or created from a file by Dunfield's
"Imagedisk".
Other than the FDD, the "A" and "B" 4145's are virtually identical.
Is the contents of the boot diskette different on the B vs the A? I've
been able to find copies of the B version, but nothing for the A yet.
The contents (files), other than versioning, are nearly identical.
Cheers,
Lyle
