Some month ago I could lay my hands on a MonJana ROM plus a German Manual. I disassembled the ROM and translated the manual into English.
Please visit my site, get my email address, email me and I will send you all the stuff.

IIRC the 3008s had only one row of DRAMs and in the second row Commodore drilled holes to make it unusable. Either the holes in your machines were missing or somebody used a trick. Could you have a look and tell us what happened inside your machine, please?
