ARGH! How did you get yours to work perfectly? Mine is an aggravating paperweight.

Yours doesn't run? :x

Mine came to me fully working. All I had to do was service the mech and install Jiffy. I also bleached the front plastics. Both of mine are the 16k ROM version of the board, which should be a later revision and might be different from yours in significant ways. The only soldering I did was to replace the ROMs and I didn't have any trouble, but the PCB is thin.

I did have to cobble up a power supply, one was missing.

Let me know if there's anything you want me to check on mine.

I got this drive off eBay and obviously someone already fooled around inside. I didn't expect to have to put in so much effort to repair it.

When you told me you have two it made me quite upset. :)

But that's OK, I have two working 1581s. How you like that? :D

The first time I saw a 1581 at someone's house, as a kid, I exclaimed: "Woah, you got a HARD DRIVE?" Was quickly corrected by the dad.

Nice, 1581 are considered forever unobtainable to me at this point.

Clone kits can be built sometimes, hopefully microcontroller or pi based versions will probably make that less painful soon. Maybe one day I'll get motivated to try that, but generally it's original hardware that makes me happy!

Prices have gone bonkers on some of the nicer C= hardware. The REUs, 1351, 1581, 128D... Nuts!

A Super Snapshot v5 just sold for 392$ CDN. I think I prefer Jiffy DOS.
