Subject: Re: AS/400 Public Auction and IBM Model 3745 (was
S/390 thread)
It will be ground up for gold scrap by 99.99% of the buyers.
Sad ending
to a nice system. I think they are some sort of modified 370
architecture internally. This is the beast that did all the
comms in /
out of mainframes before they started to use the RT type technology,
then later the P390's.
Its later than a P390, but similar in concept. You can have two CPUs in an
MP3000. You can have real disks and tapes or emulated disks and tapes. In
addition it has a built in SAN that looks like real disks to the s/390
cpu's. When we had one at work this was the most unreliable part. The
technical intro is here:-

Ours from work went for gold scrap. The cost of transferring the OS licence
is usually expensive, and the only free OS it will run is zLinux.
I know that oversimplifies the progression, but is basically the
story. I'd love to have one to play with, but the size
makes it pretty
prohibitive to think about (not to mention power, etc.)
F it has disks in the only bit you need is the CPU. It's a CPU and i/o in a
box.
I would think I could run it on an R390 with the right
OS as
well, not
sure. I know the P/390 and R/390 channels will run tape and 3174
channel attached, but not sure about whether the channels would run a
3745 or not.
The channels are real bus and tag channels and will run a 3745. However they
can have built in LAN cards so you don't normally need a 3745.
