More Amiga Adventures

I’ve been spending a fair amount of time messing around with the Amiga 1200 that I recovered from the loft a few weeks ago.  It has been a little frustrating, I’d forgotten a lot about the Amiga and its idiosyncrasies and progress has been slow for several reasons that I’ll get in to below.

One of the main challenges I’ve found with retrocomputing is transferring files to and from your retro systems.  With the Amiga 1200 this isn’t really an issue due to its PCMCIA slot which will happily read and write to standard compact flash cards with the appropriate adapter.  A PCMCIA to CF adapter was therefore my first purchase (I later discovered I already had one grrrr.)

My next purchases were an IDE to CF adapter and some Kickstart 3.1 roms.  Installing the latter was pretty easy although it’s important to note the manner in which the original chips are installed as there are more sockets than there are pins on the chips.

I then pulled out the original Seagate IDE hard disk, plugged in the IDE to CF adapter and added a SanDisk Extreme III 4GB CF card.  I booted the system with my Workbench 3.1 floppy and set up the newly installed CF card.

I divided the card into a 200MB partition for Workbench and the rest as one large partition for games and data.  After formatting the partitions (some considerable time) I made a fresh install of Workbench 3.1 and booted the system from the new CF drive. This whole process was a little tortuous as the Amiga kept crashing at various stages.  At first I assumed the CF card was incompatible but I soon realised the 128MB SIM I’d installed was causing the problems.  I swapped it out for a 4MB stick and the machine become much more stable.

The next challenge was installing AmigaOS 3.9 which is supplied on CD and at the time I didn’t have a compatible drive for the Amiga.  Using a Mac I copied the contents of the CD onto a compact flash card in a drawer name AmigaOS3.9 and inserted it into the Amiga.  I then fired up shell and entered the following command – ASSIGN AmigaOS3.9: cf0:AmigaOS3.9 and was then able to run the installer with the CF card mimicking the CD.  However I ran into a number of problems with the installation and have since learnt that using a non-Amiga system to copy files or open archives destined for the Amiga can mess up the file permissions when you then try to use those files.  After much fiddling I finally got a semi working installation of Amiga OS3.9.

I seem to have stopped using my Amiga just at the point that CD rom drives became quite widely used with the system, I personally never had one but wanted to add one now so I could install the OS properly.  I ordered a buffered IDE interface and dug out an old Plextor external USB drive.

I opened up the back of the drive and disconnected the USB interface from the IDE connector on the drive and ran an IDE cable out of the box and into the Amiga.  I had to make some changes to the Tooltypes of the CD driver that had been installed by OS3.9 to get it working:-

 

DEVICE=atapi.device
UNIT=2
ACTIVATE=1
TAB=8
LASTCHANGE=5

I now had a working CD ROM drive and was able to successfully install OS3.9 without problems and also install the Boing Bag 2 update.  My next ambitions are to replace the external drive with an internal one, I already have a slim drive from an old Cubit box, whether I have the courage to cut a slot out of my 1200’s case is another matter, and Internet access.  For now some Frontier Elite II.

  1. Hi, thanks for your comments. I remember being very proud of the A1200 and wrapping it in an old pillowcase whenever I’d finished using it, it certainly paid dividends. As you say, it looks almost brand new still.

    That’s why I can’t bring myself to take a Dremmel to it for a CD slot!

  2. With such a nice unit, I can understand that you’ve got second thoughts when it comes to making a CD slot. 🙂 Anyway, it’s great to see people that truly takes care of their old machines. That warms my heart. 🙂

    I’ve preserved mine as good as I could as well. You can find a picture and all the specs on my blog:

    I’m now going to shine up an old Amiga 500. It’s time to do a total makeover! 😉
