Doh!

How did I miss that? It's right there in the character pane of the hex editor!

Thanks Danny, that's what I needed.

Hi Jeff,

Is your website down?

According to the OS-65D users manual tracks beyond 0 are identified by $43, $57, <Track number>, $58. However, this is not what I see when I edit C1P-OS65D-3.1.65D. After track 0, then next track seems to start $24, $00, $51, $85. So, I am not seeing what I expect to see and cannot determine what is...

Nama, did you ever build or test one of these?

Life has been interesting in the house in the woods recently. However, I have been getting moments here and there to work on this project. The drives I'm using, old Radio Shack external drives initially designed for the TRS-80 model 1, 3, 4 and COCO, require the motor control line to be brought low ...

I guess it really depends what type of drives are being used, for 2 sided 8 inch you would need to jump from 18 to pin 14 of 50 pin connector , the cut would be fine where it is. i think being set up for 2 sided drives would be the most practical, the way it is the side select is used like a drive ...

Hi Grant

Maybe I'm mistaken, but won't this mod kind of break things for 8" drives?

Would it not be better to make that cut after the via that takes the drive select to the 50 pin connector (from PIN 18 of the controller)?

Thanks for posting this Jeff.

I agree, nice ends, but do they justify the means?

Ah, okay. I see there is a jumper to the right of where it says 'FT232BM' that connects the USB power. As long as that is not closed you will be fine.

Sorry for the alarm Jeff.

Jeff, Isn't that device powered from the USB?

The ones I use are:http://www.ebay.ca/itm/201332938880?_tr ... EBIDX%3AIT

If that is the case, it might not be a good idea to connect the 5V from it to your computer's Vcc.
