1) If it has a token ring card then it does not matter that it also has
Bus+Tag channel card. It will still talk TCP/IP and other machines.
2) https://www.argecy.com/2389 have microcode. Al says he got some from them
recently. I can copy the latest version but I am short of 2.4MB disks
(and in th uk)
3) Boot up the diagnostics and utility disk. It will show the memory. There
is a list of card numbers in the Maintenance Manual

4) You need 2 x 2.4 or 1 x 2.4 and a hard disk for config C6.
The smaller 3174's have a movable link for the PSU. No idea about the model
11....

Subject: IBM 3174 C 6.4 Microcode Disks?
Classic Computer Fans,
I posted this to the IBM-Legacy-Hercules mailing list. I just realized it
probably wouldn't hurt to post it here too.
I'm finally in possession of a box that hopefully is capable or can be
made
capable of connecting a real terminal to Hercules.
It's a 3174 11L. It
was
retired last year where I work. I finally got the
okay to save it from
being sent
to a scrapper. I love the build quality of older IBM
gear, except when
I'm
trying to move such gear. Between the 3174 and a
9406-520 I also
acquired, I
pulled or strained something in my left arm moving
them into place.
It's currently wired to run on 220v. I think I've seen mentioned
somewhere
that it can be changed to run on 110v. If that's
the case, does anyone
have a
pointer to documentation on what's involved?
It has dual floppy drives. At least one drive is a 2.4MB drive. But, all
the
microcode disks I have are at level B 4.6. Does
anyone know where I can
get
a set of C 6.4 control and control extension disks.
From what I've heard
those
are what's needed to enable an attached terminal
to connect to other
systems via telnet.
It has a token ring card. I will probably be able to get the MAU it was
connected to, and possibly the router that acted as a token ring to
Ethernet
bridge.
I'm not sure how much memory it has. Does anyone have any tips on
determining the amount of memory it has, and/or identifying its boards?
These are the numbers on its boards:
9210
9351
9052 z2
9053
9501
Plus the boards for coax connections.
