After soldering the Kickstart-adapter I could install the TF534. On the adapter I have KS 3.1.4 and KS1.3 with SCSI extension from Aminet.
The KS3.1.4 works 100%. I could get the WB1.3 to autoboot but with hickups. I could not yet identify the problem but the boot process is halted frequently. I can get it to proceed by pressing a key on the keyboard! Weird. But with the Workbench loaded the machine will freeze after a while.
With AutoAddRAM from Aminet I can add the 4MB of the TF534 at 40000000 to 40400000. Under WB3.1.4 it is added automatically.
So far I am satisfied with this cheap accelerator.
I now have received the TF534 and a relocator/kickstart adapter. So I opened up the Amiga. Last time I did that was 15 years ago. Still there was a big surprise. This machine is not a orginal PAL computer, but a to PAL converted NTSC machine!
There have been a few modifications to enable it as a PAL machine:
There is a small PCB on the right which function is unknown to me but might have to do with the PAL conversion. The same is true for the wiring with quartz and two potmeters on the left. Anyone who can shed light on this is invited to make a comment.
Then there is a RAM modification:
There are several ram-chips stacked on top of each other. I will try to find out later how this probable ram-expansion is achieved.
I am now trying to clean up the cabling of the NTSC modification and make it disconnectable.
Stay tuned for the next part.
I wanted an internal harddisk solution for my Amiga 1000. I have used a ACA500Plus on the side connector of this machine. Although that works very well, the pcb, that sticks out of the computer's side without housing is not very convenient. i the searched the internet and came across this blog of EzdineG. He has made a CPU relocator for the Amiga 1000 that also has an option for a physical kickstart rom so you don't need the kickstart floppy anymore. He even made a revised version that can hold 2 kickstart roms. There are some minor modifications needed of the mainboard of the A1000.
So what about the harddisk? EdzineG's relocator makes it possible to put a Terrible Fire 534 accelerator in an A1000. This board comes with a 44-pin IDE interface. You can use an IDE to CF- or SD-adapter as a harddisk. The TF534 is cheap these days because now there is a new TF accelerator that has 64MB RAM while the TF534 only has 4MB. With the TF534 and EdzineG's relocator you have a perfect combination.
As I do not have EdzineG's relocator yet, I tested the TF534 in an Amiga 500. That works very nice. The Amiga 1000 was orginally supplied with Kickstart/Workbench V1.x. So I thought it would be nice to have that version on the harddisk. But Kickstart version 1.x does not have a provision for a harddisk. Integrated harddisk interfaces were introduced on the Amiga 3000 and 600 with Kickstart version 2.x. So I looked at the kick1.3_scsi_patch from Aminet to patch a KS1.3 and add a scsi.device from an Amiga 1200. I couldn't get that to work.
My Amiga 500 has Kickstart version 3.1 installed. I discovered that with this Kickstart version you can install Workbench versions 1.3 and 3.1 on seperate harddisk partitions and select in the early startup (two mouse buttons pressed at boot) which partition to boot from. Not even a Kickstart switch needed.
