Like the FD-501 ( Radio-Shack Part Number 26-3131 )???https://www.cocopedia.com/wiki/index.php/FD-501_(26-3131) This is a Floppy Drive Controller for the Tandy Color Computer.. The ROM is MC6809 Code, not Zilog Z80 that the Model 1 uses.. Something could possibly be rigged up, but it might be better to just get the Correct Hardware....

jwse30 Posted March 11, 2023 Share Posted March 11, 2023 I seem to remember the Z-80 (models 1-4) disk drives and the original CoCo disk drives using the same cables. Don't know if the 501 still uses that type of cable though. I hope you find your answer as I'd like to know too. J White Quote Link to comment Share on other sites More sharing options...
KG7PFS Posted March 28, 2023 Share Posted March 28, 2023 Yes, it's compatible. Standard 34 pin edge connector. The FD-501 is SSDD though, so you might have trouble reading Model 1 disks. Quote Link to comment Share on other sites More sharing options...
