You should be able to use the Amiga hard drive directly on your Linux computer (provided it still has IDE support). Linux also understands AFFS (Amiga Fast File systems), at least once AFFS support is compiled into the kernel (from your "self customized" wording I would assume you know how to do that). Apparently, some Linux tools don't seem to understand ...

As far as I know, there's no authoritative source, and the information out there is probably not really accurate. I will answer this from an electrical engineering perspective, and because I have implemented some of these fixes myself. First a little note about timing fixes: The expression timing fixes is not really accurate, but comes from the observation ...

I believe it is to clean the weak CCK clock signal coming from Alice to Budgie. PCB rev 1.d4 and 2b should have this. It is on the R2 schematic (http://www.amigawiki.de/dnl/schematics/A1200_R2.pdf) - search for "BUDGIE BLUES" and check pin 36 (CCK). I think U37 ("TI 231 JFA HC08" in your photo) is a quad positive-or (74F32 / SN74S32) which is serving as ...

An hypotesis can be made by reading Gayle's original datasheet (you can find it linked here). Hardware 3.0 FLASH ROM There is provision for an optional flash ROM device. The intent is that this is a possible replacement for a floppy disk drive in an extremely low end variant of the A300. The enable for the flash rom is called -FLASH-CE, and is ...

Most likely, the two RTC devices would conflict, since they will probably rely on the same chip select line and base address $D80000. Technically, the A1200 clock port and the A1200 expansion "trap-door" slot can support 2 separate clock port devices, since there are two chip selects. These are called the "RTC" CS, which uses $D80000-$D8FFFF, and the "SPARE"...

!! EDITED to reflect settings that I have tried on my Amiga to verify. You need the following jumper settings to have HxC correctly emulate two drives This is a picture of my actual drive - it's the SD version in shape of regular floppy drive. You can clearly see that ID0A and ID1B are set to ON. Nothing else. You also need to configure the SD card ...

I can reproduce the same behavior on my A2500 with Workbench 2.1 and using the built-in AmigaDOS "Ed" command v2.00. The critical bit is the Delete ("d") protection flag. Ed's internal functionality is to delete the file then rewrite it with the modified contents. This operation fails if the "d" bit is cleared. The Execute ("e") protection bit does not ...

Each partition on an Amiga hard drive has settings that determine whether it is bootable and whether it should be auto-mounted. It sounds like your DH3 partition is not set for auto-mounting, and the other 3 partitions are set for auto-mounting. Furthermore, you have a "Mount" command within your boot drive's S/Startup-Sequence that is causing DH3 to be ...

The Indivision AGA doesn't attach to the trapdoor slot, but it also doesn't need a tower case because it attaches to the Lisa chip. (In a way, this is better than a trapdoor video card because it leaves the trapdoor available for accelerators.) It gives you video modes up to 1280x1024x256 colors, but for me it glitches at that resolution so I use 1024x768 or ...

Expanding on the comment made by @pipe: Most if not all batteries originally used on the various Amigas and contemporary peripherals are rechargable NiCd (Nickel Cadmium) cells which are prone to leak. If the battery is a common type, there is likely a drop-in replacement NiMH (Nickel Metal Hydride) battery which is rechargable and far less likely to leak, ...

The manufacturer's wiki shows that the ACA1221 provides a port to supply power to the RapidRoad USB accessory through a simple jumper cable. From the end of the third paragraph in the Clock Ports section of the ACA1221 wiki page: For passing power to RapidRoad, the white power output of the ACA1221 can be used. The RapidRoad's power connector is wired to ...

This is most likely indicating a problem with the RAM added by your expansion card. You can usually diagnose these problems better by booting with a diagnostics floppy. I would recommend trying the Amiga Test Kit v1.4. It includes a boot floppy that runs a suite of tests, including a memory test that will probably recognize your additional RAM and can ...

I had a leaky battery on my Apollo 1240 card (it is the same PCB as the 1260) and desoldered it and replaced it with a Panasonic VL1220-1HFE rechargeable coin battery. Now the original battery had three pins, and the panasonic has two but I think the positive and negative terminals are marked on the card so just make sure you solder onto the right holes. The ...
