Hi, all

I thank you all for your interest to my 100TPI problem. I've read with a great interest Herb's site and found lot of interesting stuff on this subject. Certainly, the worst thing that I've discovered is that this kind of drives has only an interest for our small 8050 & 8250 users community and (don't know how numerous now) S100/VG systems users. During last 30 years, those devices have certainly been dropped away in a much more important proportion than other "obsolete" stuffs as completely unusable in other systems (or falsely found as defective if plugged on any PC-like system).

Well, all that to say that we're not helped with this luxuous at the time but now fully exotic disk format. I've found on eBay a "Micropolis part number 1115-VI" that seems really a familly parent with the 1006 (locking mecanisn is different from 8050's one but main motor seems to be identical) ... I'm just asking me if it would be a great oportunity to get at least a "100TPI compatible" electronic board or just a good idea to "drop money by the window" ... it's quite cheap but shippment cost is quite huge.

If anyone had technical details on the 1115 to help me in my decision to take it or to let it ...

Thanks a lot - Regards



I *think* that the 1115-VI is a 96TPI unit; both the electronics
_and_ the mechanical assembly are quite different from the
1006 used in the 8050, but AFAIK the stepper/screw/head
assembly is compatible.

Personally, I'd wait for a 100TPI Micropolis or Tandon drive to 
show up on eBay or elsewhere; as Bill points out, even on a 
good 100TPI Micropolis drive you might have problems reading
your 8050 diskettes. 

Would it not be easier to read the disks on a real 8050?
