# PiStorm

Use a Raspberry Pi to emulate a 68040, SCSI for an SD card, and [[amiga:retargetable_graphics|Retargetable Graphics]] for high resolution displays.

## PiStorm32 Lite

I picked one up at https://amigakit.amiga.store/pistorm32-lite-commodore-amiga-1200-p-91306.html

* Software: https://github.com/michalsc/Emu68/releases/tag/nightly

## Partitions

You can have up to 3 hex code `76` partitions. Emu68 doesn't see the others.

## SD Card and Amiga partitions on Linux

I used KDE Partition Editor to create blank partitions, then `fdisk` to set their types to hex code `76`, just like in the official directions: https://michalsc.github.io/Emu68/tutorials/SD_Preparation.html

### Mounting partitions elsewhere

Trying to mount from the SD card the PFS3 partition with FS-UAE fails and causes the emulated Amiga to crash. It works fine with FFS, but the partition needs to be marked as not bootable for it to work.

I would suggest making a 12GB FFS long filename partition on the SD card so you can transfer WHDLoad or TOSEC or whatever over to a larger PFS3 partition on the actual Amiga.

## `cmdline.txt`

* If you have a Slow RAM expansion, `move_slow_to_chip` turns it into Chip RAM if you have a 8372A Agnus or newer
* You can watch the GPIO pins on the Pi for changes. For instance, add a switch to pin 27 that selects which Kickstart version to boot:

```
[gpio27=0]
initramfs kick13.rom

[gpio27=1]
initramfs kick31.rom
```

## P96 config

## Amiga 1200

### HDMI & SD Card access

I bought and printed https://cults3d.com/en/3d-model/game/amiga-1200-back-trapdoor-hdmi

 * It required a little tweaking to the model for the HDMI and SD extender cables I bought to fit, otherwise it fit the backdoor perfectly.

## Issues

* Installed into A1200, booted fine off existing CF IDE card, gave the machine 300MB+ RAM
 * Version  Emu68-pistorm32lite-20230310-f9cd01.zip 
* Plipbox stopped working
* Will swap in ACA1233 and see if that gets Plipbox working again
* Plipbox works with ACA1233, will swap PiStorm once again and see if there's an easy solution
* PiStorm swap, same result

### Network Stack

* MiamiDX is not working, will try Roadshow
* NEVER MIND disable burst mode: https://github.com/cnvogelg/plipbox/issues/3#issuecomment-216959582

```
makedir ENVARC:sana2
echo "NOBURST" > ENVARC:sana2/plipbox.config
```

Reboot, and OMG is this thing fast.
