Nope.  Lots of other projects (including work and a major kitchen remodel).  ;-)

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)?
