Hi All;
I have a Tarbell controller, single density. But, I don't know IF I have it wired right. First for 8" floppies, and second for 3.5" floppies... Yes, I know the 8" are a 50 pin, and 3.5 is a 34 pinout... Also I think the Main Chip 1771 is Bad, where do I Get another one ?????....
I also have a double Density controller that came with my Z-80 system, and would like to use it on my Altair (8080).... it is a SBC 880 system...I have the schematics and the software listings, but when I try to match things up to write software for the altair things get mixed up. there are more ports and under different names than the Tarbell...
THANK YOU Marty
