Take a look at this directory: https://vintagecomputer.ca/files/Apple/Macintosh/Tecmar/ Look for "Mac Drive content". It's everything on the drive I can see. I think FEdit is required but I'm not sure. This is the info screen: Have fun. Santo

Thanks JDW. I appreciate the advice, As an avid collector, I check eBay usually more than once a day. I also have a long list of saved searches in case I miss something. The Syquest SQ100 and Q-Pak are already on there. Looks like a few sold in the last few years. I'll keep an eye out...

The MFM emulator has an "analyze" command-line parameter that will try to figure out what the drive is. It figured it out by itself. If there was any interesting software on it, I would have used the MFM emulator to emulate the Tandon hard drive and play with the volume structure to see if...

Got my Tecmar Mac Drive running. I had to recap the power supply and replaced a transistor. I also had to replace a shorted tantalum capacitor on the -12v line of the Mac Disk PCB. Thankfully, the 10MB Tandon hard drive was fine. I was able to archive the hard drive with Gesswein's MFM...

Charlie V3.0 U51 = 27128 Emily V4 U93 = 2764

I have not tried to mess with 8748s but it does have 1K of programable ROM and I do have a programmer that will do 8748s. I could see if I have another 8748 for testing and see how/if it works. I'd hate to try it on a MacCharlie 8748 without testing it first.

If I can help, let me know. I did have one of the keyboard extensions open but unfortunately, I don't have any pictures. If there was firmware in it, I didn't save it either. I do have the other ROMs inside the MacCharlie but not the keyboard firmware, if there was a ROM in it.

You're right. The "teeth" on the right of the tray fit tightly into the bottom of the MacCharlie so it almost becomes one piece. The Mac then sits on top of it. If you want dimensions, I could measure it. I also have a second MacCharlie that is missing the tray but it also is not working...

Very nice to see another one running. Do you have the bottom tray that the MacCharlie and Mac sit on? Looks a little low or the keyboard is propped up. Congrats!

Sadly, the first half of that 2716 EPROM is either empty or not read properly. 0x0000-0x3FF is all FFs. 0x400-0x7FF is similar to the second half of 251257-02A but not exactly. Makes it interesting. Hopefully the EPROM is not messed up or the 8250 Mini board will not work. EDIT: Never mind...

Congrats and good luck. If you need an image of the MS-DOS disk that came with the MacCharlie, let me know. EDIT: I posted archives of the diskettes I have here: https://vintagecomputer.ca/files/Apple/Macintosh/Dayna_MacCharlie/

I am in Richmond Hill, just north of Toronto in Ontario. At the moment, we have a postal strike and it's best to ship with USPS. Shipping by courier will incur Border entry fees even if the item has no value. and that adds complexity. Let's hold off for now but I definitely want to try it...

I do have the right drive mechanisms and would be happy to do that but I am in Canada and these days, shipping to me is fine but having something go back to the US is not something I am willing to do until things change. There are more hoops than normal to jump through and I won't do that for...

Did you ever find an answer for this? From what I could find and figure out, the add-on "8250 mini" board adds a second drive to the SFD1001. I have a Commodore 8296D with dual internal floppies using the same drives and the dual floppy controller board doesn't look like this. I also have...

Thank you. This will help tremendously. Much appreciated and I appreciate the time markers too :) Looking at my Mac Drive power supply, I saw some caps are out of spec so I made note of them for replacement. I saw two caps that were the same value but one was taller than the other. As it...
