## Processor

Amigas run on [[:m68k|Motorola 68000 Processors]].

## Amiga 1200

### CF card in PCMCIA reader

* What worked
  * Transcend PCMCIA -> CF adapter
  * SanDisk 512MB
* What didn't
  * Verbatim 4GB
* You can't use an Amiga FFS or similar card in the PCMCIA slot. It has
  to be FAT16 or FAT32.

### Networking

#### In a MiSTer

If running in a [[technologies:mister|MiSTer FPGA Emulation System]], you need to set up PPP networking on both the MiSTer and in the network stack config. Follow the PPP networking instructions there, then come back here.

##### MiamiDX

* Have MiamiDX use the PPP IP address and set up everything else so it makes sense for your network.
* If the connection starts acting weird, reset the UART and reconnect in MiamiDX

#### Plipbox

An Arduino-based Ethernet adapter for am Amiga's parallel port. It's not fast but it works.

* https://lallafa.de/blog/amiga-projects/plipbox/

I ended up getting this one: https://amiga68k.com/?product=plipbox-deluxe-commodore

You may need to enable `NOBURST` on certain configurations, like on [[:amiga:hardware:pistorm|PiStorm]].

##### MiamiDX config

#### Wifi

* Cabletron RoamAbout 802.11b card
* prism2.driver
  * Get the prism2v2 so you can get WPA2
  * WirelessManager runs in the background and handles the connection
    to the network, while MiamiDX does the TCP/IP stuff
* MiamiDX

##### WPA2-TKIP

* I needed to set up hostapd on a Raspberry Pi to
  create a slightly downgraded access point that
  bridged to the rest of my network.

  ```
  # hostapd.conf

  wpa=2
  wpa_key_mgmt=WPA-PSK
  wpa_pairwise=TKIP
  rsn_pairwise=CCMP
  ```

## Gotek

* [Floppy writes in FS-UAE are cached via overlays](https://fs-uae.net/docs/floppy-images)
* The USB drive needs to be formatted `fat16` and you need two files
  at the root of it
* My Gotek has two buttons. You use the two buttons to move back and forth between the mounted
  ADFs
  * Some Goteks I think have rotary encoders as well
* You can't put new ADFs into the rotation without a reboot

### If Gotek eats the partition table

It's possible for the Gotek to eat the partition table on a USB drive. It should be recoverable if you use `testdisk`: https://www.tecmint.com/install-testdisk-data-recovery-tool-in-linux/

### LED Display

I have one of these: https://www.waveshare.com/wiki/0.91inch_OLED_Module

It plugs into the LED pins. When I got my Gotek it came with the display in a Gotek cutout box, so I'm assuming `display-type = oled-128x32-narrow` is stored in flash memory. More details:

## Audio

### Retargetable Audio

Use AHI. You're probably using it with Paula anyway.

* http://aminet.net/package/driver/audio/m68k-amigaos-ahiusr
* http://aminet.net/package/driver/audio/AHI-Paula for a better Paula driver.

### Internet Radio

AmigaAMP is what you want.

* http://aminet.net/package/mus/play/AmigaAMP3-68k

Then, load this prefs in AHI config (http://www.amigaamp.de/Binaries/PaulaPrefs/ahi.prefs) and save it. Enjoy your streaming audio.

#### AmigaAMP

* Skins
  * It can use WinAMP skins. Here, use this one: https://skins.webamp.org/skin/99543ffaf75f2e6e99e8541605115d40/Sabrina_Amiga_ForeverAMP.wsz/
  * You can `unzip` a skin into its own folder in `PROGDIR:Skins/` or install a decompressor library to handle `.wsz` files directly.
