As part of the migration I'll also be setting up an email server associated with the website.

If anyone wants an @commodore-128.org email address let me know :)

Later on this month the forums will move directly to https://www.commodore-128.org and away from the this temporary site.

Once I have the exact date I'll give a few days notice - the changeover should be seamless; all of my testing has been good so far with only a couple of small issues that had to be worked out.

The swap should take an hour or two at most.

Today was the first day of the Amiwest Show 2024 in Sacramento, California.  Morning and early afternoon had seminars, and the late afternoon had a swap meet.  Go to

P.S. There was a C128DCR, a C64, a 1541, and a 1701/2 monitor at the swap meet!

Sweet!  Which reminds me that I should have Ray Carlsen install a modern power supply in my C128DCR.

Truly,

Here are photos I posted way back when of the fan mod to my C-128D.  I tried to reattach them to my original post but that didn't work.

The second photo is somewhat out of focus because the camera I had at the time didn't do good closeups.  I have a much better camera now, so at some point, I may take a fresh set of photos that will be in focus.  Also, I will remove the power supply assembly from the computer so I can get a shot of the discharge side of the fan.

It's not a dual-drive assembly in the same vein as, say, an 8250.  In a real dual drive, both mechanisms have the same device number (8, 9, etc.) and a specific mechanism is selected in the command string by specifying 0: or 1:, e.g., RUN "1:MY_PROG",8.

In this dual 1581 unit, the two mechanisms have different device numbers, so the CBM DOS commands that could copy from one disk to another in a real dual-drive unit won't work.  Any copy program would be working through the serial bus to read from the source disk and write to the destination disk.  It could be made to run pretty fast by using the burst mode routines published by Commodore with the Dev-Pak assembler, along with an algorithm that understands the physical disk layout well enough to minimize the effects of rotational latency and track-to-track seeks.

With all that said, the copying speed will be limited to whatever the serial bus can deliver, which won't be nearly as fast as what even the old MSD dual drive could achieve when internally copying from disk to disk.

Yes, I thought I saw the software on-line somewhere so that you could copy from one drive to another in the dual 1581.

Ready for the Bay Area Maker Faire tomorrow,
