IBM 3174 C 6.4 Microcode Disks?

[Dave Wade]

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

3R_Maintenance_May89.pdf

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....
