Title: Do It Yourself buffered IDE for A600/1200?
Post by: gizmomelb on August 20, 2006, 02:11:39 PM

Hi all,

just curious if anyone's ever made a buffered IDE board for use with an A600 or A1200?

I found some unbuffered boards/circuits on Aminet, so obvious question time - what's the buffering actually do and how would it be accomplished?  Is it really needed?

T.I.A.

I made the unbuffered one from one long cable, 5 connectors, one resistor and two diodes.

I used it for 4-5 years (until the A1200 retired, it didn't break), without any problems. In my opinion the buffering is not needed. YMMV.

the 1200 only uses one of the most basic and slow ide modes pio 0 or 1 iirc. so buffering is not really neccissary. if it used one of the more advanced modes like some accelerators and all pcs do it would need buffering. also if you have several devices using different data standards buffering is needed. like if you have 2 hard drives and a cd and a burner.

I had 3 HDDs and a CD-RW drive for ages. I had no problems.
