Is anyone interested in directions how to make an amiga high density drive from a normal
pc high density drive. I have worked out a scheme to do it and it works !!
The drive works exactly the same as an amiga high density (1.66 Mb or 1.44 Mb for Crossdos)

If you like it i will post the information and an iff of the thing.

This is a short sign off to reduce delay on the internet !

That would be great! Is it very difficult to do?

Post the hack up so we all can see it! It would be great to use a High
Density Floppy on our amigas with a cheap PC drive. Thanks!!

Oh, I think there might just be a bit of interest in something like
that...

YES! PLEASE POST!! CAN'T WAIT TO SEE IT!!!

Me too, I'm interested in this. Any chance of sending it to Aminet as well?

I would also be very interested in this hack.
please send me the docs.

my email addres is may...@en.ecn.purdue.edu.

also if anyone knows how to hook a a500 up to a vga monitor I would appreciate
it.

Please post or please send uuencoded to dark...@ncw.net or
dark...@golden.ncw.net. If it seems reasonable, I may be willing to
assemble these kits for others. Tried to email you, but was no dice.

Yes, upload the file to Aminet. And if the file is not too big, post it
on this newsgroup.

YES, post it! Perhaps you should put it on Aminet as well. What's your trick for
making this possible? How much hardware?

Yes please do... I have an IBM HD drive sitting here collecting dust and
well um one of my DD drives DIED so I would like to use it.

No I don't think so, it sounds plausible. I too am interested in how it was
done.

As far as I can see in the circuit diagram here a few days ago, he slowed
down the floppy rotation speed by using a divide-by-2 on the floppy motor
clock.

>Tom D Tek

I was working on something similar, but now I have to wait for a new CIA
and a PC floppy drive. My machine crashes when I double click in WB. :(

Hmmm. What about DRV144.lzh ? Its on Aminet, and is supposedly a way
to connect a high density floppy drive to an early Amiga.

Seems like doing it this way (without modifiying the flux density when in
low speed mode) would cause read/write problems due to the lower RPM's.
Can he format a 1.44 on the AMiga and actually read/write to/from
it on a Clone?

BUT you can only format to 880K NOT 1760K. It works. I have seen it. I'm his
friend :-)
