#retrocomputing question: I'm trying to boot my #macintosh #powerbook 170 from #floppy . So i used a #linux machine with #dd to write a known good #system7 disk image onto a known good #floppydisk .
But dd exits reporting an i/o error while writing. Note that I can create working #msdos floppy with the same drive and same floppy. Also tried other floppies, same error and every time at the same place (44kb from the start).
As expected, the mac won't boot, but for a little while I see the happy mac icon, so it seems the first part of the disk is correct.
Is there any mac-specific parameter to pass to dd? Any other hints?

One of the joys of being an old analogue fuddyduddy is re-reading personnel rosters/ credit notes that you won’t readily get when streaming. I already knew Steve Hillage ( #Gong #System7 #MirrorSystem ) had produced a couple of #SimpleMinds albums….what didn’t register until today when whipping out the 1991 System 7 debut and seeing the name-checks….Mick Macneil….on accordion….shoulder to shoulder with a veritable who’s-who of #EDM #Ambient music at the time

I'll check it out.

You have to understand, when I was getting heavy into computers circa 1990, vector fonts only existed in high-end printers, and via fairly expensive software ("Adobe Type Manager").

Then in mid-1991, Macintosh #System7 came out with its own awesome TrueType system and vector fonts, and I was in hog heaven! I could see fonts at 127 point and see the details of EVERY curve. Absolutely perfect!

Also perfect was the fact that those fonts were being rendered at 72 dpi on monochrome, and used hand-drawn/tweaked bitmapped fonts at low point sizes (24 pt and below, except for odd in-between sizes like 11, 13, etc.)

Nowadays, the screens I use are much higher resolution, but NOT "HIDPI." They're also full color.

So, bitmapped fonts are OUT, even as a backup for small point sizes. Fuzzy antialiasing is in -- neither the really nicely pixel-oriented AA of windoze, nor the "screw the pixels/hinting, full, perfect vector shapes ahead!" AA of MacOS.

So, older eyes, 96ppi screens, AA... it's a fuzzy existence.

I love vector fonts in principle. I still can't get over the crispness of nice bitmapped fonts at low resolutions in practice.

This is a recent revelation to me.

As silly as it is, since I have access to both physical devices capable of running, and locally-run emulator copies of, Mac System 7, this is still wonderful to see.

Someone has managed to embed the Mini vMac emulator into their website and run it using Javascript in the browser.

And yes, Dorothy, you can even run it on your phone (though it looks like the aspect ratio of my phone's screen is a bit different than the native resolution of a Mac Plus)
