Amiga Indie Hardware Developments

Something like this?: http://lallafa.de/blog/amiga-projects/plipbox/

This guy's project is basically an Arduino-based bridge between the Amiga's parallel port and one such SPI serial Ethernet module. Looks very interesting!

He also do lots of other boards for classic computers (cartridge emulators, test board for Spectrum, among other cool hardware).

Will contact him about the floppy emulator.

Sorry to say this but :

1 - The "Victor Trucco" floppy emulator design is the HxC Floppy Emulator : He took all the HxC materials to make this floppy emulator :

Este emulador foi baseado no projeto original de autoria de Jean François Del Nero HxC Floppy Emulator

This emulator was based on original project from Jean François Del Nero HxC Floppy Emulator

Very interesting to learn that my design was sold by someone else without my agreement...

2- The SD HxC Floppy Emulator is able to write to the SD Card from beginning and have the Amiga Write support since the revision C (2010).

22/08/2010: Firmware SD HxCFloppyEmulator v1.3.0.0
- Amiga Write support added :

Note to the Revision B PCB owners :

To activate this new features you need to add a Microchip 23K256 SPI SRAM chip and 4 resistors.
The connection to do is :

23K256 pin 1 -> 220ohms resistor -> PIC18F4620 pin 22
23K256 pin 5 -> 220ohms resistor -> PIC18F4620 pin 27
23K256 pin 6 -> 220ohms resistor -> PIC18F4620 pin 28
23K256 pin 2 -> 220ohms resistor -> PIC18F4620 pin 29
23K256 pin 8 & 7 -> VCC3.3V (this voltage can be found at the capacitor under the sdcard connector or at the output of the regulator)
23K256 pin 4 -> GND
23K256 pin 3 -> Not connected.

(a 100nF capacitor is also recommended at the pin 8 of the 23K256)

After this modification you should see the message "SRAM OK" at power up.

I remember doing this mod from Rev.B to Rev.C based to your notes Jeff.

Where exactly can one buy the SIMM ZIP RAM Adapter? Is it currently available for purchase from anyone?

Try using the contact page at this site if you want one for A3000D: http://www.amigaworld.de/hardware/simm-zip-ram-adapter/

[toddbailey]

For my A3000, I just purchased 16 mB of 70 ns fpm zip memory from quest components for a reasonable price.

is converting to simm memory better that what I have?

This link seems to be down - is there an other one?

[dalek]

great link - here it is at archive.org: https://web.archive.org/web/20171017....net/Indie.htm

this type of content would be better served on a wiki somewhere - maybe the eab one?

[sigma63]

Thank you Dalek!

[confused2]

EDITED: oops, nevermind somehow missed the last 2 posts. Sweet! thought it was gone!

[Daedalus]

Yeah, it would be nice to have a replacement - archive.org is fine for recovering old stuff but it can't be updated, or have broken images or links fixed. At the moment there are loads and loads of homebrew hardware projects available, right up to replacement motherboards. A Wiki somewhere would be a good option.

I have some sort of "poor mans Wiki" thing going on here:
https://exretro.com/amiga_ihp_wiki/doku.php?id=start

If I set it up right, it should be possible for other to register and add content / create new pages.

Its mostly a listing of tags, so you use the wiki to search,,, say.. "CDTV RAM expansion" or something like that and it returns the links of the pages with those tags. From there you basically get a link to the developer, not a direct link to the product (mostly to reduce administration).

Let me know if I have missed some neat device.

Hope it provides some assistance to our small community.

Website does not seem to work anymore.

Unfortunately, I am too busy with life and Amiga projects I am involved in.

I wish I could have days of 35 hours to be able to continue with this endeavor and other Amiga related stuff. I think the idea I had would still provide a much needed indexing service for this community.

The easiest thing to do would be just to setup a github repo and make a .md list there; people can submit PR's for additions/changes to the list. You can add additional people to manage the repo and so it doesn't rely on any single person to keep alive.

Wikis and pages set up by individuals require maintenance and time and while I'm not saying github will live forever, it's unlikely to go away at least for the foreseeable future - and being git, it's easy to move elsewhere and keep a local copy.
