Grant,

Okay. More progress. Got to A*. Typed INI. Sure: Y.

I immediately get ERR#3. "Track zero write protected against that operation." I tried different diskettes and got the same result.

I'm now going to clean the sensors to see if that clears the error.

Ok, The adventure continues. With immense help from Grant and Dave and others, I've reached a point where I'm cross loading code from my Mac to my C1PMF in an effort to build\write Disk #5 of OS-65D. My floppy drive is behaving oddly at a critical point in the process and I'm working to diagnose tha...

Mike,

I just got the replacement IC for U58 and will install it this weekend. Tom

BillO,

4800 without jumpers and cutting traces ??

Hello,

I'm looking to purchase (or commission building) a data separator compatible with the 610 board and its pinouts for floppy drive connectivity. Inviting offers....

Dave, Once again, thanks for all the guidance. I'm going to implement the mod to get the baud to 9600. But before doing so, would appreciate your read (or anyone's) about a few modifications made by the previous owner of the c1p I'm working on. First, U67 and U68 have IC's installed both accompanied...

Is there a POT on the 600 board that I can adjust to get better horizontal centering of video out? I'm using an upconverter to connect the composite out to the HDMI port of a LTD TV. Looks greater but the first character on the left side of the screen is truncated. So characters 2 through 24 display...

Hi All, I'm posting here the code for a single-user game I wrote for the C1P: Lunar Lander (in the spirit of the great Atari video-arcade game). This was probably the most efficient program I ever wrote (in BASIC). I can't find the .wav file which I have somewhere -- am still looking for it. Please ...

Hello,

I'm trying to restore\reconnect a bi-directional RS-232 port to my C1P. It has all the necessary electronic components but wiring between the 600 Board and the port is messed up. Can anyone point me in the direction of a clear explanation (and schematics) for that mod?

Thanks, Tom

So, if I want to load programs through that port, I may be stuck. The other board I have has the same RS-232 components installed with a DB25 that has all the normal wiring -- but the wiring on board (and the trace cuts) for the cassette\serial port switch are very different than those on the workin...
