Hey there, Yeah, as far as I can understand, any RS232 TTL Controller will do, just make sure it has a TX, RX, 5V and GND. Personally I'm considering going for a USB version that does serial port emulation but that's because motherboard doesn't have a serial port. I think I'll have to buy one soon too, seeing as my friend has given me his broken 7200.11 and I'm running on one right now and expecting it to burst into flames any second! P.S. I'm in the UK too and the cheapest (USB one) I've found so far is around £10ish on eBay, although I don't really fancy waiting 2 weeks for it to ship from China Let me know if you find any cheaper ones
