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 http://bitsavers.org/pdf/ibm/3174/SY27-2572-4_3174_1L_1R_2R_3R_11L_11R_12R_1 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....
