Building an Amiga 500 Relocator with Flash ROM
When using an accelerator that replaces the 68000 CPU in an Amiga 500 you often need to use something called a relocator. This is because the card gets in the way of things like the keyboard in the Amiga, so the relocator moves the socket somewhere else. The two common ones are straight relocators which Read more
Trying Out Even More Amiga 500 Plus Upgrades
My journey through trying out Amiga upgrades has been continuing recently with some minor changes to my Amiga 500 Plus. These ones are a little more minor but still useful. Read more
Building a Terrible Fire 536 Accelerator
I already have a Terrible Fire 534 accelerator, but Terrible Fire created an improved 68030 based accelerator for Amiga 500, Atari ST and similar machines called the TF536. This accelerator uses a 100MHz crystal which clocks the CPU at 50MHz. Whilst it does not have an FPU like the TF534, it does have 64MB of Read more
Converting a PC Floppy Drive to Amiga
I recently purchased an external floppy drive the for the Amiga which was sold as “untested”. Unfortunately “untested” in this case meant “doesn’t work and someone did a bad attempt at repairing it”. There were parts of the drive physically broken and it was beyond repair. I lucked out because unlike the Rotec drive I Read more
Programming Xilinx JTAG from a Raspberry Pi
Many modern Amiga cards use Xilinx chips for everything from a basic CPLD for auto configuration to full blown CPU replacements. My Terrible Fire 534 accelerator has two of these chips and they are field programmable using JTAG. It turns out a Raspberry Pi can be turned into a programmer for these, so this is Read more
Mounting the Amiga SD Card HDD Outside the Case
Now that my Amiga 500 Plus uses an SD card for a hard drive the most annoying thing is having to open up the case every time I want to change the contents of the SD card or switch the card. So, I figured out a way of mounting the SD card outside the case. Read more
