Entry 20th July 2018: Post 01: Amiga 1200 - PC525

Amiga 1200 - PC 525 Issue 1A Part I

Hi.. Looks like the crap summer weather is here to stay. I get up
each day praying for rain and all I get is the shite sunshine. It
really does make the upstairs in the house unbearable. Like now.
never mind. I am also still struggling with this crap LUMIX. It
really has no idea how to take pictures. If I do anything other than
the auto function I get yellow on the pictures, even under my white
lighting. If I increase the lighting the image goes darker. Reduce
the lighting and the image goes blurred. Macro ' ALWAYS ' brings in
the yellow on the image. And I have to take a gazillion pictures
off a monitor screen to get a good one.

So with the crappy heat and the camera issues I'm frazzled. Tragic
really when you enjoy what you do so much and are prevented from
having fun because of the shite weather and a shite camera.

Moan over.. let's get busy. I don't give up... trust me.. EVER !!

I installed a new 2.5" in another A1200 today. I had resisted ever
using large drives in the 1200 for fear of them falling over. Given
that the last 40GB worked a charm I am ready to install another in
Amiga 1200 No 06 Bryoni from Bristol of all places. I did acquire
an amazing amount of my kit from Bristol. No idea why.

Bryoni is fitted with a little known card. I say that cus I wasn't
able to find anything about it on the web. I am starting to go
through the magazines to see what I can find. The card in question
is a RAM card made by Power Computing Ref: PC 525 Issue 1A. Has
no accelerator as such but with the PSU appears to go twice as fast
as the stock 020. Though this may be fooling Sys Info and processes
may be faster in only certain circumstances.

And so I do the do again and as ever record everything I do. So
let's head on down to the Amiga hanger and see what we have for today.

Amiga 1200 No 06 Bryoni

Got up early to avoid the burning heat
and headed off down to the Amiga hanger.

Dust covers off to reveal my freshly cleaned
Amiga 1200 No 06 Bryoni and the newly acquired
2.5" hard drive and ribbon cables.

Exact same model that I used on TuMoon.

The quite rare Power Computing PC 525.

4MB RAM card with the FPU and Clock.

View on the card from the inside.

Original 3.0 ROMS

The shielding was touching the card.

Also lifted the corner to ease any
shielding issues with the card.

I acquired some quite small ribbons
as the ones I had were a little long.

This cradle was a little stiff.

The 40GB Seagate laptop drive.

The cradle was causing a problem so
I swapped it out. Now seats better.

Camera alert. Pictures not the best. I will
need to experiment a little more or simply
get another camera. So sorry for that...

OK I boot on the floppy and no hard drive
visible, though the drive light did flicker.

Just checking the ROM for the install
disks that I need to use. 3.0 ROM.

Whilst in Workbench I flipped in the
INSTALL disk to check the drive though
when actually partitioning the drive
I booted with the INSTALL disk.

You must use the INSTALL disk to partition
the drive as the Workbench disk does not
have the FastFileSystem on it.

Opening the HDToolBox shows the drive as unknown.

Click the Change Drive Type and Define New.

And then read the configuration.

The drive needed is the one on the top
of the list. Each time I do this the
software saves to the disk. So those
others are from other sessions with
other hard drives.

OK we now have the drive listed.

Time to partition the disk. I do not format
from here. And NEVER Low Level Format.. Ever.

Simply move the slider to a partition size
that suits your needs. Start with DH0: and
make that bootable. It really is the only
partition that needs to be bootable.

Click in the rectangle of you partition
and click New Partition. It may say that
its not empty. Just do it again until you get
a white shaded box. Change the name of the
volume to DH0. I tend to keep the Workbench or
DH0: which is bootable to under 1 GB. This is
where the system install will put the OS.

Name your other Volumes sequentially DH1: DH2 etc.

Next click in the adjacent area which will go
black and slide to a convenient size and then
do the same but no need to make bootable. Other
partitions I make 2GB max.

The OS only can handle 4GB drives so a 40GB will
make so sense to it. To fool the computer I just
leave a very small blank area at the end to stop
drive looping round. Works for me.

OK and save changes and reboot with the Workbench disk.
There is no OS on the system hard drive as yet
but you should now see the volumes or partitions.

Format each drive from the drop down
menu and maybe avoid putting in the trashcan.

This could take an hour or so.. be patient.

It is very likely that in rebooting
after a format you can still lose the
drives. What I do is simply do a
Quick Format.. and that does the trick.
