Re: [emax] Re: another emax 1 + CF reader problem

2011-12-16 by Ted Summers

The ATA compatibility of the CF card could be messing things up.... what does it say is the max transfer rate- the page doesn't indicate?
If this is PIO / DMA capable then that may make it a higher speed card and the response times may be too fast for Emax.

Keep in mind (as I have posted many times), Emax use a 5380 SCSI 1 controller with max transfer of 1.5M/s

ATA is 33/66/100 or even 133 M/s

So you can see how the data volume and potentially the timing might overwhelm the bus.

As to the HD- maybe someone else can comment on the compatibility of the drive.
I have never put bigger than a 40MB in my Emax 1.

Verify that you actually have the TERM resistors in place.
My drives had resistors that were removable and the TERM jumper.

I had to buy the TERM resistors as they were missing from the drive....
They were cheap (like 50 cents each), but without them you aren't terminated.
Just because a jumper is there and on doesn't mean the resistor networks are there.

In that case- if you have an internal terminated cable, you would remove the TERM jumper and use the cable.
