Re: PiStorm

There doesn't appear to be any schematic, but according to the sources it's a simple 16-bit GPIO interface. Probably wrong, according to a post on English Amiga board" http://eab.abime.net/showthread.php?t=104462 PiStorm at least uses the SMI bus. The sources do not agree with that assessment....

Is it done by RPi GPIO oder did they at least use the SMI bus? There doesn't appear to be any schematic, but according to the sources it's a simple 16-bit GPIO interface. Probably wrong, according to a post on English Amiga board" http://eab.abime.net/showthread.php?t=104462 PiStorm at least u...

Re: PiStorm

JLPCB gets its parts form LCSC, they are sister companies. They have a fairly good reputation. Okay so Chinese. That explains it. I never purchase ICs from such sources. Out of curiosity, I looked up some of those PLD in stock at an authorized distributor. For stunning 41.08 € - more than the whole...

Re: PiStorm

From what I've seen the bootup is relatively fast (they seem to use a very lite installation for the Pi) Not very light, it is the standard distro without GUI. I use that also. and powering down is just shutting the machine off. Which can cause data loss, and seems criticised in the Amiga scene. I ...

Re: PiStorm

Don't have the time to watch the full video, but two things seem odd at first glance: 1. They mention "prices as low as about 13 €" while the PLD alone (no PCB, no assembly, no small stuff) costs 21 € and has delivery time January 2022. China fakes? No fake, they use JLCPCB for assembly a...

Re: PiStorm

Hopefully there could be a QL option in the future. I would think twice before putting any work into that. ⋅ Do you really want to boot a full Linux first, before the QL comes to life? Taste varies, but for me the answer is definitely no. ⋅ Do you want to run a shutdown before p...

Re: SGC problem with QL ROM emulation

Yes. But then it's the question if a QL with just some sort of RAM expansion makes sense at all.
Looks like Tetroid GoldCard costs only little more than anything providing the necessary RAM for SD card.

Re: SGC problem with QL ROM emulation

A hardware design with RAM at $0 is probably less work than debugging a fundamental OS change. Some sort of RAM expansion is needed for SMSQ/E anyway, and also for QL-SD.

Re: SGC problem with QL ROM emulation

It will be difficult if not impossible to include a SD-card boot loader in a QL ROM and still have it accepted by the SGC since you cannot just leave obsolete parts like the MDV driver out. Many thanks for your assessment, I suspected something like that. :( On AH/JM ROMs there is about 4.5KB unuse...
