I gather that some one has the Dave Gershwin board working with a 3174.
Was that
you.
You also need 2.88 format for the 3174 floppies.
Any one modified any
of the floppy emulators To work at this density.
Yes, that?s me but I have had issues with the emulator starting up reliably so
that the 3174 boots.
So still not fixed?
Nope. Lots of other projects (including work and a major kitchen remodel). ;-)
Actually, the format is 2.4MB (2x 1.2MB). It?s a
5-1/4? format instead of a 3-
1/2? format.
Sorry been working on my PC Server 500, I assume the data rate is double, so the existing
devices are not easily modified?
I don?t know.
One of my other distractions is trying to get OS/2 (any version) installed on my xSeries
232 so that I can run it as a P/390 and everything is fighting me on that (bad RAID
controller, to it not wanting to boot off of a floppy). I finally gave up and purchased a
copy of eComStation but that kernel panic?d somewhere during installation. I haven?t even
had time to put in a support call. :-(
Oh and did I mention that I?ve acquired (just need to move it) an IBM 4331 mainframe
including *all* of the peripherals (3340 disk drives + lots of packs, 1403 printer, IBM
tape drives, card reader/punch, 029 keypunch, manuals, terminals, etc, etc)?
