And now, box for the controller.

The same guy who designed the box for the AmpliBus, has designed a box for the controller and one disk drive. You can see the good work at: http://retrowiki.es/viewtopic.php?f=40& ... p200086115 :shock:

Re: CoCoMEM-512 for CoCo 3.

Hi coco.oric! The CoCo3 is a great computer, I have it and I'm enjoying very much using it.

Re: Convert a byte as hex string (to display on screen)

Indeed it is a nice piece of code! I never manage to make the correct comparisons or use of the decimal mode for these things. :) By the way you can also use a 16-byte table (4 bit value - ascii code) and even save a few more cycles. No need for comparisons nor additions. Not sure about total cycle...

Re: How to install a 3" floppy drive on a modern pc?

I have a Gotek with HxC firmware as drive A, and real 3.5" drive as drive B. Only convert .dsk files to .hfe and copy hfe to USB drive. On real Oric boot on hfe then use command BACKUP A TO B.

Re: Compatible transister ?

Three transistors, TR1 in tape input circuitry (collector connected to pin 18 of VIA 6522), TR2 in keyboard interface (collector connected to pin 13 of VIA 6522) and TR3 to activate tape relay. All them working in commutation mode.
