Sorry it took so long to get around to this.

So I booted OS65D3.2 (NMHz), and checked $267B and it was indeed $62, so it looks like my C4 is running at 2mhz.

As always, thanks for the info.

Hi Dave, Thanks for the reply. I always assumed the C4 was running at 2mhz, but now that I think of it, maybe it was the C2 that was at 2mhz, and the C4 was at 1mhz. Is there anyway to tell without pulling the machine apart? I only ask because every time I pull it apart, it usually doesn't work afte...

Hi,
Been wondering how to change the 505 board from 2mhz to 1mhz operation.
My best guess is to re-jumper the 4mhz clock entering pin 12 of the UGD Counter (7493N) to pin 9...but yes, that's just a guess.

Cheers

Hi Dave,
If you email me some examples, I maybe able to match the font.

Great news about WP-2
Not so great about WP-3

Thanks for your efforts.

Phil

Great!

Don't forget the 30+ OSI docs I scanned.
These are sitting in our shared dropbox folder.

Cheers

This is fantastic news.
I was planning to download it last weekend, but work became all consuming. This weekend I'll give it a spin.

Thanks for all the hard work.
Having tools like this makes osi life much more enjoyable and easier.

Philip

Fantastic!!!!

Good to hear the return of Erik's disk went smoothly.
I got confirmation he received them safely.

We're now well underway with our OSI library!

Phil

Were you able to get the some high res images of the boards before you built them up?
if so, is there a place where they can be downloaded?

Cheers

P.S. your machine is a work of art!
