1200z question
6 messages in this thread
Is there any chanve that a 1200z memory expansion could stuff up the
A1200s 40meg Internal drive if the jumpers weren't set correctly??
I've just bought the A1200 and installed the 1200z board straight
away. It doesn't have any RAM on it so I left all the jumpers. Now,
the A1200 has errors on the drive. I was wondering if that is just
coz it is rubbish or the accelerator (68881) stuffed it up??
Check your jumpers against the documentation. Make sure they are set correctly.
Also make sure that your maxtransfer on the drive is not greater than 64k minus
512 bytes.
MaxTransfer?? I didn't change a thing out of the box, should I have. Sorry to
sound dumb, I had the A500 for 5 years so am a pretty experienced Amiga user
but I don't quite follow you.
BTW In the documentation when it says that a jumper should be 'ON' does that
mean it should totally cover both pins or should be one on one off?? I take it
is on both = 'ON'.
PS> Where do I change the maxtransfer value?

Andre: Maxtransfer is a Rigid Disk Block setting on your harddisk.
You can use HDToolbox or our own RDPrep to change it. If the drive
was dealer installed rather than CBM installed, they might not have
set up the Mt value correctly: IDE drives don't like MT's bigger than
64k (minus 512 bytes).
A jumper is on when both pins are connected.
Hi!
Just thought you'd like to know that it seems the Harddrive problem is from
Commodore so the 1200z is cleared of any wrong doing 😎
I'd like to let you know that I think your boards are excellent. Made in the US
too, and they look REAL SEXY. Pity they are so expensive, but if you want
quality I guess you gotta pay for it.
Thanks again for all the help

Thanks for following up on that, Andre. And thanks for the
compliments. We could lower our prices if volumes in the Amiga market
were anything near what they are in the Mac or PC market. O' well.
And, yes, we make everything right in Texas, USA. Some of the chips
are fabbed offshore –but we have no control over that of course.
These days, Americans are actually pretty competitive when it comes
to building electronics. Regards, –Redmond
