The solo mining instructions say you must use an address starting with a 1?

The wallet can only generate addresses starting with bc or 3?

How can anyone use the solo mining instructions correctly if the wallet will not generate a correct address?

From index_STRATUM_MINING.js :

Modify the above code to add YOUR BitcoinV address:
"address": "1GPLaBLsczMDDNSueiwbxouGDfLaoxhopq"
change to
"address": "your address here"
****Make sure your address starts with a '1', not a '3' or 'bc'

This miner only supports GCN cards. Older VLIW cards like HD6XXX series and some HD7XXX cards are not supported.
Check the AMD GPU list on wikipedia and you can find which models are GCN.
