Wow guys lots of great information here. This exactly what I hoped would happen. Development work has stalled as I expected because of the Thanksgiving holiday here in the US. I …

Larry Pina has a very clear procedure for doing this in his book Mac Classic & SE Repair and Upgrade Secrets. It was a very common upgrade at the time. Books can be found r…

It may be best to see if you can find somewhere to mount a standard computer fan and find one to suit. Click to expand... Larry Pina has a very clear procedure for doing this i…

Jameco, mouser, digikey would probably have them

That's called a squirrel cage fan. It's more common in industrial and automotive applications, and, as you have surmised, is not a common or readily available computer part. It m…

get a metric ruler, go from there, its one of 3-5 sizes Click to expand... It is approx. 70mm tall with a power lead running nearly the length of the analog board. From your p…

presumably the later drives change speed depending on which track they're on, so one should be able to do the same thing with an emulated version and not bother counting pulses. …

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…
