2k, starting tomorrow I will be working with some old school 64k ram and the arduino on a non related project, to see how easy/bad it is If the mac is generating the pwm on the ea…

The PWM signal is well documented in Inside Macintosh and Apple Macintosh Family Hardware Reference. A PAL reads the disk-speed buffer in RAM and generates a PWM. However, the 800K…

If you are going to emulate the 400K drive itself, it is completely dumb. What it receives is encoded RLL data which goes thru an amplifier straight to the write head. To read, the…

Have you come across the Catweazel? Catweasel Disk Controller ISA Catweasel is a universal floppy disk controller that uses unmodified PC diskdrives. The Catweasel can read …

without having to vary the data rate. Click to expand... That's a good thing, right? In terms of building an emulated peripheral.

or a Ham license and packet radio hehe

You should AT LEAST get dial-up. 8-o

...but its better than my old dialup so im not complaining Click to expand... It's better than what I've got: I have to leave my home and drive 25 miles into town when I want t…

Oh and i forgot to mention that it's very unreliable... pingtest gives me an F and 5-10% of the time the connections down I cant wait till Insight, Sigicom, SBC, Comcast, Insight …

I wouldn't be able to turn it into anything server-y as my isp has 1 ip for _everyone_ on each tower, so no incoming connections. Click to expand... Tower? You mean on each wir…

Looking at the Mac drive pinouts I just Googled there's a pin labeled "PWM" which says "Motor speed control". If you can find documentation as exactly what sort of signal is presen…

Floppy disks are like record players Click to expand... No they aren't. Floppy diskettes are like records. Floppy diskette drives are like record players. Also they aren'…

For those interested my notes so far. I think I am going to go buy a printer, because I hate reading on the computer. Can't scribble notes on the pages that way. :-D Click to e…

good selection of notes! and I use arduino quite a bit, the programing of it is pretty easy, you should have little issue picking it up (ps if you have any questions and the ardui…

I've done some embedded systems work before. In college my senor project was a 4'x2' display that showed the internal data flow of the pipe line of a MIPS process. I designed the …

Aww. That's a bit of a bummer. Hm.. What else? Can't really think of anything other than putting old games and stuff on it and trying to find a place for it.

do you have an oscilloscope? Click to expand... Yes I do, but is one of those cheap Radio Shack Scope Pens. I think it only goes to 2MHz, but that should work for this. I thin…

Really the thing is that I don't have a bloody clue how you make a floppy disk drive work. So I think I need to expand my search to floppy disks in general and then focus on the Ma…
