Re: Introduction

Good luck :) shouldnt be too hard, i have to do the same for my 80A tape drive and replace the belt, works fine with tapes it records but very temperamental with existing tapes. What amazes me is how well this stuff still works!

Re: Introduction

Hi and welcome. I just sold 2 MZ-1F11 as I was having a clear out (under orders!!). The problem with them (at least the 2 I had) is the drive belt, it ages and stretches and thus the disk doesn't spin at the right RPM. I never got to change the belts but I did strip down the drives to clean them aft...

The 80K version should run but the disk format is different and not readable with the 8866 disk controller in the 80A and if you look at the disk images in a hex editor ...

Even tried PCPM80 from an MZ800....

Re: Introduction

Hello All, Just an introduction and to be honest I was quite shocked at the number of people still using the Sharp machines! Regarding myself, too old to mention but still 15+ years from retirement!!!, my first Sharp was the MZ80A which my older brother bought and it ended up being given to me, then...
