Oddly, the issue only happens with the 7.5 installer...Guess I have to go back to the drawing board with that one.

It's 7.5.3 (the one freely-distributed on Apple's site). Guess I should have been more specific. :I

Yes, but it has been since I've gotten it, and like I said, I've reinstalled the system many times.

After experiencing some weird occurrences (menu bar disappearing) on my Performa 6200, I decided to format and start fresh. I zeroed the drive, and attempted to install OS 7.5. I b…

IBM PC's, even with an 8088 (wow!) used a DMA controller for floppy disk because of the data rates. You could j…
IWM in the Macintosh is similar but not identical to the Apple ][ controller. There's a / device out there that emulates a physical floppy drive and works with the Apple ][ / calle…
A few years ago I attached 7 DuoDisks to a IIe for fun... that's almost 2 megs of online storage! I think I used ProSel as a program launcher. It really worked quite well.
Incidentally, you can make your own view new posts URL that excludes other parts of the forum (or, more properly speaking, only includes certain parts of the forum) by mucking arou…
That can be simplified a bit by enabling the sub-forum search option (&sc=1) since phpBB doesn't distinguish between forums and categories – so the forums listed on the ind…
This seems to work, the major drawback being that changes to the forum may break it.

This is probably a "doable" project, but it's going to involve at least some hardware. (IE, I don't think you'll be able to get away with just a cable linking bare pins on the para…
You could do a really crude approach where you actually format the "disk" using the Macintosh and simply record the output signal at a suitable resolution, it's still a digital sig…
Perhaps a combination of a parallel port and a soundcard for the analogue waveform. Sounds horrendous, but it would be a good stepping stone on the way to a microcontroller based …
A floppy port is expecting to talk to spinning media with sectors and tracks and critical signalling and timing.
It's expecting to receive a waveform taken directly from the read …
Try looking up information on the Apple II disk controller, then find out what the differences between that and a Mac are. If I recall correctly, they are quite similar.
The idea was that I could write a program to run on my box that takes a mac disk image, and serves it to a real mac via the parallel port through the mac's floppy port. This would…

Great score, the AppleVision 1710AV is a fine display, I've had one for about 6 years, and its probably my favourite CRT, though mine only works properly at high resolutions (1024x…
It's not a dumb question, because an answer requires a basic understanding of how drives are setup on the Apple II. (I'm going to ignore the Apple III, because I know nothing abou…
