Thanks a lot. My drive is still functional but another
that I've
been communicating with has troubles with his drives. I think
this is just what he needs.
I'm not sure why the designer of this circuit used buffers on 4 of
the signals? I'd think these could be just directly wired. It does
require that the drive be 720KB compatible. Many newer drives
don't support this but it looks like the NEC drive mentioned
is relatively easy to get.
I (me?) also don't know. I have a Philips VG8535 (or 8235? Oh my!) which
had a complete drive failure. I just put a normal 720K drive using the
turbo-r tutorial, no buffers, just wires. It works flawlessly. I just need
to find a broken MSX2 to get a S3527 IC (MSX2 Engine, be dammed!) to make it
work like new. It has one of the joystick buttons permanently pressed, due
to a failure on the S3527. So I can't play games with that.
As soon as I fix that, I'll make it a MSX2+. You can see a photo of it
on www.tabajara-labs.com.br (everything in portuguese, but babblefish is
there to help you, and the photos are great! :D)
