I'd be surprised if you find a PowerPC build for a Fortinet VPN that'd be compatible/have the right ciphers to connect to something modern.

If you have the .img, that's a floppy disk image, so you should be able to write it to a floppy disk. Not sure if Macdisk Tool supports writing floppy images to disks, but give the steps on this page a try to use WinImage https://www.classic-computers.org.nz/blog/2011-12-29-disk-from-images-mac.htm From my experience, copying the executables directly between Windows and Mac, not using .img files, doesn't seem to go well because of resource fork stuff.

They're available on Digikey, but at $15 instead of 10

Hi all, I have a manual inject drive(MF355F-592MA) that's not accepting disks. It was in a Performa 410, I went to put a disk in, it gave the couldn't read disk, need to format it, error. I hit eject, it struggled and spat out the disk, so I popped it open to take a look, and while I'm fairly familiar with the mechanics of the auto inject drives thanks to the various videos/tutorials out there, there seems to be a lack of info about any sort of cleaning/lubrication of the manual inject ones from my online searches video of issue - https://www.youtube.com/watch?v=MWL7VrOfqqU

Not sure about writing disks with a Mac, but there's a way to convert a PC floppy drive to plug into the parallel port of a PC, so you can write Amiga floppies http://m1web.de/ADTWin/#Cable

Can you post some more pics(back of the case, and inside)? Would be cool to see Nice find!

I don't have a picture or anything handy, but there's a 2nd set of holes in the same area of the logic board that will fit a PRAM battery holder. https://store.retrofixes.com/products/macintosh-se-pram-holder is one place to buy the battery holder, there may be a better/cheaper place to buy it

Can you re-upload the pictures as a jpeg or something? They're a .heic which PCs don't get along with

You know, I've seen the name DiskDoubler several times, but I always figured it was some kind of disk compression software for hard drives, so I ignored it thinking "I have plenty of space on all my machines, why bother!" Now I wish I had looked into it in the past, that would have come in handy so many times!

I'd be interested in like, 8 full sets. Over the years, many of mine have walked away

http://www.pacificcable.com/Picture_Page.asp?DataName=SC38 According to this site, it's a non standard connector created by Apple, so not sure if you'll find it on Digikey. Not sure where all these 3rd party adapters were getting the connector though Worse case you might be able to measure the pitch of the pins and find another connector with the same pitch thats 6 columns x 5 rows and use that

Yeah, would definitely be a nice option. This one appears to be the correct adapter as well https://www.ebay.com/itm/HDI-30-pin-to-DB25-SCSI-port-adapter-for-legacy-Macintosh-systems-552/253843270894?epid=165012110&hash=item3b1a3cecee:g:xeAAAOxyqUpQ89G4

It looks like you'll also need a HD50 to db25 adapter for that, since the 68net uses db25
