#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?

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.
