IBM 3174 screen controllers UK

Folks, I think I now have too many 3174 controllers. I have 1 x Rack Mount - Token Ring Card + MFM Disk Emulator 1 x Large Tabletop - Token Card 1 x Large Tabletop - Ethernet Card <=> I am keeping this. 1 x Small Tabletop - Token Ring card but won't run TCPIP code. If anyone wants one of these I am happy to ship at cost but they are 220/240v and heavy so shipping to USA may be a problem. I have a selection of floppy drives that can be fitted but I recommend using a Gotek with FlashFloppy firmware. I also have the following spares:- 1. working PSU for rack mount 2. non-working PSU for the rackmount systems but I am sure it can be fixed 3. spare motherboard for rackmount 4. spare token ring card (if I can find it) 5. (I may have memory modules but can't remember where I put them 6. I think I have a 3299 multiplexor some where Feel free to e-mail off-list with questions. Dave Wade G4UGM & EA7KAE
