DriveWire4 using an HD63C09EP cpu  on a Tandy Color Computer 3. Below is a text file sent to Discord today, modified again of course. Notes on how it got done. PTB/2020/05/26 I started with: Nitros9-6309L2-3.3.0-dw-30M.dsk (I forget which one that was used here). The files that were needed were obtained from BarryN's .dsk (Discord) I listed on paper with a pencil, the modules  that were missing but were inside of  NITROS9/6309L2/MODULES, rbf & scf. I added llide.dr and i0-ide.dd ( my already setup IDE-hdrive)  to have some permanent storage while I collected those  above modules to one location: /i0/DW6309  for ease of finding them while using kwikgen. At first i missed the module 'dwio' but made  sure that it got installed. All modules are loaded at boot and not added with LOAD. I will try and include the "MDIR" list.  First was a "mdir >/rd0/foo" (ramdisk)  Then "list /rd0/foo > /C1"  then finally found

A 16550 serial port. Here begins another project PCB. This one has a UART 16550, a Lattice 2032 CPLD for addressing selection,  and a header for a FTDI-232-5V USB cable. Plus a small patch area Two jumpers for address selection. Several jumpers for wiring connections to the FTDI header. LED for power, LED showing USB has power coming in. LED showing the "FAST" cpu mode. Update: 2020/05/08: It's working at 406800 8N1 baud using a "KTS14,3G2" crystal and xmode bau=6. There was a "challenge" in getting the original crystal to run at each power-up. Addresses: $FF60-FF67 $FF68-FF6F and one custom: $FF28-FF2F. (this one seems broken) With one jumper left, another two selection range could be added. Measurements in mm. As sent in for fab. Here it is plugged into a buffered Y-cable while running NitrOS-9 EOU5. Two of the yellow LED's are lit, one is USB power and the other is PCB power. The third L
