IO_CH_RDY on an A4000 - does it go anywhere?
« on: May 01, 2013, 10:28:55 AM »
Hi people,
Still trying to work out why this 4000 just doesn't grok ATAPI devices at all.

I've noticed that pin 27 (IO_CH_RDY) on the IDE bus seems to go nowhere on the schematics - is this an error? Is it supposed to connect somewhere? Seems a bit daft to have a signaled pin on the schematic that goes nowhere at all... and may be (possibly) related to my problem.

Anyone know?
Thanks!

Yes, that's what I thought. The same pin on the A1200 is called "/WAIT".

But it doesn't seem to connect to anything?!
