[Techtoolslist] ABI Boardmaster 4000 chip adaptors

[Andrew Finn]

Hi

Does anyone have any info / circuits on the 75188 adaptor ( also known as the mc1488 rs232 transceiver) so these can be tested in the ABI boardmaster 4000? There is also a 4116 ram adaptor too so the boardmaster tells me!! 

Google on this occasion is not my friend as it comes up with nothing out of the whole of the Internet!!!

Many thanks
Andrew
