Sometimes, I can't remember when filming this particular time. I can sometimes do it all with what is in the spoon tip, occasionally need to add a tiny bit more to the tip. The board is HASL, so the solder already on the board helps a lot with fine-pitch work.

I have not tried yet, but I would imagine any games that aren't using the Amiga custom chips and run a little slow will likely benefit. Pretty much any Bitmap Brothers games for example.

Hi, 1. Yes, the PiStorm32-Lite lacks support for multiple DMA bus masters. 2. It is because the DMA start signal (BR) is being used to disable the onboard 68020 in the A1200. That is a design flaw in the A1200. It would be possible to do in machines that have the PiStorm replace the CPU (A500 for example), but it hasn't been implemented (yet) on those. There is an upcoming PiStorm which might. It will also be a requirements when we make the A3000 / A4000 version. But on the A600 and A1200, I don't see this ever being possible.

I did get your email about it, replied but my reply bounced. I will reply again using a different account. I will attempt to reproduce your issue over the weekend. I have the exact hardware you have available to do so. It might just be a flashing software bug with that combination.

@@linuxjedivideo Okay, thanks for your swift reply. No need to rush of course, but it's good to test our hardware out in different combinations of course, so that eventual bugs can be eliminated. I remember how e.g. the Pistorm had a hard time initially, but it's definitely come a long way by now. 😀

@@brufnus you have no idea how many odd combinations I've tested against, and still a few strange ones come up. In the last year I had to modify the hardware slightly so that GVP hard drives worked properly :)

@@linuxjedivideo Yeah, I can imagine, haha :-D But that's part of the fun. I had a floppy drive on which so much wasn't working; there was too much slack at the stepper motor, even the heads were misaligned and in the end I had to resort to TrackDiskSync, which worked amazingly well. That floppy drive I used for booting and flashing today, by the way. 😀

Unfortunately, no. They don't make one big enough. For that I recommend the Wera Chip Lifter. Which kinda looks like a bent screwdriver, but is much better at lifting chips.

In the longer version of this talk (which I haven't given officially yet) I do talk about the fact that it was probably possible, but would have required significant investment that wasn't worth it at the time.

Would the motorbike game be Crazee Rider? I enjoyed that a lot, as well as Syncron, which was a crazy-fast game.

@@linuxjedivideo yes you're right. Crazee Rider. That was tough as nails when I was a kid but seems so simple now. I think I had all of these as part of play it again Sam collections.

Unfortunately not. Several Unix systems used it and some arcade boards. I suspect at the time that the cost vs benefit wasn't worth it. As for the CD-i, that was an SCC68070 which was 68010-like but had a bunch of extra things to make it more of a microcontroller.

Fun fact. When the Amiga prototypes were presented to Commodore Miner, Sassenrath and many others prefered the 68010 because it runs faster per clock, but Commodore wanted to use the normal 68000 because it was much cheaper. It's a shame the first versions ended up the way they did. Commodore Braunschweig was the first inhouse development team which took the Amiga seriously and developed the A2000 and ALSO presented a prototype with the 68010. Guess what happened ...

@ oh wow this blows my mind.! also commenteer before who mentioned 68070,, im assuming this was a lie?

@ Nope. The SCC68070 is in fact real. It's a normal 68000 developed by Phillips but with internal extensions like a MMU, DMA and a timer.

I would recommend a 3A+ for Amiga 500/600/1000/CDTV, 3B+ for Amiga 2000 and Pi 4 or CM4 with adaptor for Amiga 1200. Pi 4 is only supported on the PiStorm32-Lite. Pi 3B+ will only fit without modification on the A2000 and A1200. The PiStorm32-Lite supports Pi 3 series and 4.

@@linuxjedivideo awesome thanks for the response. I ended up getting a 3A+ for my A500. Im considering trying the Lazarustorm too, but people have said it could cause issues.

@@TwickenStep I am not keen on Lazarustorm myself. The key reason is the E clock (a clock for the CIAs generated by the CPU) for the internal CPU and PiStorm are sharing a trace. This is bad for a number of reasons and I'm more surprised it works at all. That being said, I've heard of people being able to use it.

Not sure what chip uses that spec, sounds more like QFN territory. I might use hot air / hot plate for that (which is what I do for QFN).

@@linuxjedivideo 👍

Luck, basically. It sometimes works, but is definitely isn't supported for now. It operates at a speed out of spec for the GPIO in a Pi4. In general, as new Pis come out, the GPIO latency increases (Pi5 will always be unusable for PiStorm). We have an idea for new firmware to solve that in the original PiStorm, but it is lower priority than other things.

@@linuxjedivideo Thanks for letting me know. I thought there may be a new version of the CPLD firmware locked behind the Discord wall. As someone who cannot join Discord (I've tried), it is distressing to see more and more open source projects getting locked into megacorp walled gardens.

@@ffsireallydontcare with PiStorm, most discussion happens in Discord, but all firmware/software/hardware is on GitHub. I didn't decide where the community was created, but it is where people have gravitated to.

@@linuxjedivideo I get it, but it's still concerning as I won't have anything to do with Zuckerbot, and Discord bans me just after the application process but right before the account landing page finishes loading. Why? "Trust and Safety" won't tell me. Odd given the longest I've been able to spend on Discord was 2 weeks, and that only involved a brief chat with both Michal and Claude about the possibility of using the PCIe lane instead of the GPIO for the Pi4 to Amiga communications channel. Progress! I have noticed that some of the related Discord servers are bridged with IRC, which is nice. Now to get everyone to move to a newsgroup and/or a public forum. Thanks again.

Not really, no. The entire chipset is still in use, especially for the AGA version. That is no more true than saying that an 030 accelerator with an RTG makes an Amiga a passive spectator.

I used "essentially" here because I was over-simplifying for those who hadn't seen one before. It may not have been the correct word, or I may not have had my words in the correct order, but it was not redundant. It was an unscripted video, I recorded in a small window of spare time, so filtering my use of language was not high on the priority list.

@@linuxjedivideo Precisely. It was unscripted and so your natural word usage was allowed to propagate unfiltered. And your unfiltered use prefixes sentences with "essentially" when it's not needed. Essentially it's a resistive DAC that plugs into your parallel port. Could have been: it's a resistive DAC that plugs into your parallel port. See how you used the word "essentially" to embellish your sentence, trying to sound clever? Guilty as charged!

All EPROMs need a modification (or adapter) for rev 3 and 5. If you load DiagROM into ROMulus, it will "just work".

As of about a month ago, Emu68 added beta WiFi support. The RISC OS Open code would likely not be compatible because the init and driver is entirely on the 68K side talking to the hardware, written using Amiga's libraries.

I guess it mostly depends on your use case. It is rare that I use the battery iron for work that would require more power than this gives. Ideally I'd like a slightly longer working time, and the second revision that has recently been released gives this. The graph can be useful for power usage more than heat, the heat is going to be almost instant and constant on the smaller cartridges anyway. If I wanted small tip, power for large ground planes, etc... I'd probably reach for my TS-80P, but I'm finding it rare that I need to use that. Usually my regular JBC T245 iron/tips cover everything else.

@@linuxjedivideo That's right. In today's electronics industry, which is advancing by leaps and bounds, tools like soldering irons are becoming more and more popular and intelligent. The only regret is that it is not possible to truly get rid of the shackles of wires. Of course, there are many varieties of soldering irons now, but in the final analysis it is just an ordinary heating tool. One aspect depends on how users use them. I agree with this. I am currently using a Bakon BK210 battery (18650, 3200mAh) iron, and also use the C210 soldering iron bit(≈2Ω), and to sleep and wake up at any time to make the battery more durable. Its only disadvantage is that the battery cannot be replaced more conveniently and the maximum power is only 12W[You see, the actual maximum power may be smaller P=U²/R (≈7W)]. It would be even better if it could reach 20W like JBC's B-Iron 210.

Sure, the trapdoor STL can be found here: www.thingiverse.com/thing:5980829 The Pi from the PiStorm32-Lite adds RAM, disk and HDMI (via an RTG driver) for now. A prototype pass-through video device exists right now to put the Amiga AGA graphics into the Pi's camera port to show on the HDMI too. No WiFi or USB yet, but I do know WiFi is being worked on. It also loads any Kickstart ROM file you want from the SD card to boot from. Michal's Patreon feed covers the software/driver development side quite well: www.patreon.com/michal_schulz

@@linuxjedivideo Thank you very much. I like the way you presented. I hope you will do further video for significant updates

I suspect the biggest issues are: 1. It might need an MMU (Amiga Linux does), and neither PiStorm implementation provides this. Although Musashi can have it with some minor code changes is. 2. It likely needs Unix specific SCSI drivers to talk to the SD card.

It's not really that surprising - the 68k series stopped evolving architecturally back in 1984 when Motorola decided to refocus their efforts on PowerPC. If we lived in some alternate universe where the 68k architecture got another 3 decades of development as happened with x86 then by now we would have some incredibly fast 68k parts. I wonder what the 68k 64 bit extensions in this parallel universe would look like?

Then don't 🙂 It is not for everyone, and that is OK.

Unfortunately the way FOSDEM works is that a topic gets a room for either half a day or a full day, they can fit as many or as few talks as they want in it. But to make it fair to everyone, 20-25 minutes is pretty typical for a talk. To be fair, every other talk I saw in the Retrocomputing Devroom was great. Amiga OS is still developed today, which is great. My Amiga 1200 was running the latest 3.2 release.

Thank you. This is actually a cut-down version of a much longer talk I had planned to give at a museum last year (and would be on TH-cam), but things didn't go to plan. Maybe later this year.

I didn't know DOSBox_RTG was a thing, but taking a quick look, it should run extremely well. As for CAMD, I don't think there are plans right now. That isn't to say there is opposition to doing it, but things like WiFi and USB drivers are a higher priority. It is open source, so you are welcome to contribute patches to support this.

That can probably be done using Musashi. We do something similar to access the Pi's Linux CLI from the Amiga.

They were all coded to the lowest common denomination for easy porting. Which made them a bit clunky. I have another video which showed that due to the tight loop memory copy they do with sprites, using a 68010 with Xenon II is much smoother than a 68000.

@@linuxjedivideoInteresting find. As the 68010 is always said to deliver no significant improvement. I actually have an 68010 laying around and planned to put into my A600 using an adapter socket (which I bought for maybe a tiny bit better performance and especially being able to use a quit-key in WHDLoad. I think this adpater would also overclockd to 14MHz IIRC), but could not get around to do so, yet. Looking forward do one day see Xenon II as it should have been :)

@@elmariachi5133 for the most things, the improvement is minimal. There is a tight loop optimisation that is about 50% faster, but it is only in very specific circumstances. Luckily the Bitmap Brothers games hit that state often.

There is a very long answer to that which in summary is "it depends, but that isn't always the case". But, does it really matter? There are very few things the current chip RAM performance impacts. Compatibility has been achieved with pretty much every game and demo that exists now.
