Please send me the address of the supplier. I'm in desparate need of one. I tried replying by Email, but we had some trouble with the net recently and my reply won't go through. Thanks a million!!!! Second : To all you people at Commodore (and any others that can help). I learned ML on a Z80 and was thrilled to hear of one in the 128, now I'm wondering if there is any way you can switch in a bank of RAM and I/O and then turn on the Z80 so that all ML can be Z80 code. I see no reason why this couldn't be but I haven't seen any meantion of it in the reference guide. I know the Z80 can be activated with a bit in the MMU, but I haven't tried it because once I activate the Z80 I have no idea where to put my Z80 code so that it can find it!! I much prefer the Z80 to the 8502 and I'd love to use it extensively (with the VIC, SID, and MMU of course). By the way, why did you guys do the CP/M BIOS in 8502? I'm still struggling with that one, too. Thanks for any help... Devon E Bowen University of Buffalo
