>> Ah thanks for that!! I have had a dig around in the box of bits I got with my boardmaster and HAVE discovered I have the 4116 adaptor!! It generates the +12v and -5v well from the 5v supply using a 556 some caps and diodes! But when the boardmaster is set to 75188 there is only 2v at the supply to the adapter, so wondered how the supply's were generated in the 75188 board, when I can get round to it I will have to document the 4116 board as it appears to work fine generating the voltages but don't have any 4116 ran to test it on

>>> Hey,The 4116 adaptor is covered here (near the bottom) http://www.ukvac.com/forum/abi-b4k-test-basic_topic339944.html I've tried to gather as much info / files as I could since picking up my boardmaster but I've never come across any adaptor info for the 75188. There doesn't seem to be that many people that own / use the bm4k these days though which doesn't really help. Judging by the serial numbers I've seen I don't think abi sold more than 200-300 units and how many of them have survived... so that probably explains it.
>>> I recently got a message from a german repairer / abi4k owner that passed up the long lost masterlink software at some computer fair / flea market as he didn't know what it was at the time and so far hasn't been able to track down the seller. :/
