Mindblown: a blog about philosophy.

A friend came over with his beloved Amiga 500 and wanted me to help him get Kickstart v 3.1 installed. It turned out to be a rev.5 motherboard. The kickstart is basically a part of the Amigas OS, and the software is stored on ROM chips. The Amiga 500 has only one ROM, but other…

The Final Cartridge III Plus is a remake of the original Final Cartridge III, but it has several awesome new upgrades. The best one is that it can also speed up modern SD-Card solutions like SD2IEC and PI1541. This cartridge is fun to assemble, and many people think that the fact that there is no…

I decided to make my own Pi1541. Notice how I made a IEC output for cable in the middle there. I did it because the 6PIN DIN cables are hard to find, and expensive too. With this, soldering your own would be easy. I put the IEC connectors on the same side as all the…

I decided to make a fresh batch of my old Retro4fun PCBs. This time in RED color. Its basically just an adaptor that plugs into the Parallel Printer port of any Amiga and gives you 2 extra joystick ports, for a total of 4 joystick ports. Some of the Amiga games compatible with 4 player:…

I really love my MiniPRO TL866 programmer. It has so many supported chips. I save a lot of money not having to buy several programmers for my hobby. But unfortunately it does not support 27c400/800/160 eeproms. When restoring Arcade games, I some times come across those ROMS. A common fault for old ROMS is that the…

Its always fun to make your own things. This time I decided to make some memorycards for me and a couple of friends. I now have 2 A500 without trapdoor memorycards, because they had battery damage. So instead of buying another old more or less battery acid damaged unstable card, why not make brand new…

This project was initially made for the purpose of using an internal Amiga floppy as a secondary drive for copying disks. But later, I added jumpers so that PC floppies can be used too, since these are easy to find. I later also found it useful to have a jumper selector for selecting DF1:, DF2:…

I really wanted a PS/2 to Amiga adapter, so I ended up making this PCB in Eagle CAD based on information freely available on the Internet. I ended up making one that can use both USB and PS/2 connector, and the option to change between Amiga and Atari ST mode with jumpers. It also works…

After finally getting hold of a Commodore CDTV, first thing I noticed was that it did not have the usual DB-9 connectors that the other Commodore models have. The machine did have a mouse port, but it turns out it is not a standard one, and I did not get one with the machine, so…

Have you ever wanted to use a Gotek on your Amiga without having to make changes to the Amiga itself? I think too many Amigas are being “mutilated” to fit a Gotek these days. Instead you could use the internals of an external floppy, and change out the floppy with the Gotek. problem is, many…
