Amiga 1200 MaxTransfer
OK meet Jermaine
She has an external 3.5" Seagate IDE.
The hard drive was originally in my
Colossus Windows95 Pentium 120 from 1995.
The ribbon feeds out from the Amiga's
internal pin connector and out through a
small slot cut into the casing.
Power is provided from the floppy drive
port. The PSU is the A500 heavy brick.
A standard A1200 PSU wont generally work.
The ribbon has to be modified to work
with the different number of pins
between the IDE and the Amiga pins.
I have another one of these 1GB drives.
And various cables of differing lengths.
Note that the last four pins are vacant.
Difficult to fit the shielding so it
is missing from this computer.
And so she is ready to rock and roll.
The hard drive simply sits out the back.
I do have a Power Computing external casing
but seems hardly worth the effort.
All was working fine until I tried to
to use software copied from a whole disk.
DOpus just wouldn't work from an ASSIGN.
I decided to check with the other drive.
This time mounted inside.
Clean installation and yet same problem.
I could run DOpus from the floppy.
And also if I copied the files over
one at a time. But not if I simply
copied the whole disk.
Also the ART 1 and ART 2 pictures from
DPAINT plus DPAINT itself refused to work
when I copied the whole disk.
Yet when I copied the files over one at
a time they worked without fault.
This all pointed to an issue with MaxTransfer.
Problem was that I couldn't get HDToolBox to
enter in either a rate of 0x1FE00 or 0xFE00
until someone pointed out you have to press
the RETURN key after entering the number and
not just hitting the OK button.
Note that you get to MaxTransfer from clicking
CHANGE when you call up the Advanced Options
when formatting. You can change the MaxTransfer
at any time. It does not affect the data
on the drive.
I decided to download HDInstTools from Aminet
to better check those MaxTransfer settings.
Some don't like the tool. I had no problem.
And there we go. Worked like a charm and
I was able to access DOpus and DPiant
from a copied disk.
And the drive worked just like she should.
So I set IDE MaxTransfer to 0x1FE00.
As you do !
[ Update 4th September 2018 ]
I have been using this computer to create
a series of animations using VidiAmiga. I
have a SONY DVD player connected to the
VidiAmiga digitiser and a Toshiba TV and
also a Parnet connection to my wonderful
A1200 in the 2000 case for back up.
I have to swap out the Parnet cus the Vidi
use the same Parallel port.
I have a 4MB PCMCIA card cus in truth that's
enough to support the necessary file sizes.
I keep animations to around 2MB in size. They
tend to grow when I save in Anim8 on MainActor.
The VidiAmiga saves in Anim5 but the frame rate
is very slow. MainActor cures all that. I also
have the key for MainActor so I don't get
the annoying pop-up.
Sadly I hit a snag with the 3.1 ROM as it refused
to show the LowRes interface in DPaint and also
point blank refused to show part files from
edited animations in VidiAmiga. Added to the
fact it wouldn't run Arcade Snooker from a
How do I know its the 3.1 ROM well in the end
I pulled the 3.1 ROM and replaced with 3.0
and then installed 3.0 over the top of the
3.1 Workbench and it solved all my problems.
So I'm good
Jermaine works just fine. And I have been
able to make use of busted drives from 1995.
Just needed the 3.0 ROM, WB 3.0 and MaxTransfer
set in HDToolBox to 0x1FE00... Not hard, or is it.
That's retro for you
