Quote We're starting the year with a bang! Today we're announcing two new versions of BlueSCSI: Ultra and Ultra Wide. These new models support faster Ultra SCSI connections to better support more high-end workstations and SCSI cards. These are more than iterative updates and continue our 100% original hardware designs and GPL firmware. Source: https://bluescsi.com/ultra Anybody looking for more BlueSCSI power?

I, for one, am very impressed by these new BlueSCSI's. I have a v2 BlueSCSI mounted internally in the Q700 I am using and I continue to be amazed by what it can do. I'm really, really tempted to get one. Props for them also supporting the v2 in parallel. One thing I did not find any information on: will there be a version for 25-pin external SCSI? It kind of defeats all the increases in speed but it is mighty practical.

That's awesome news, @Bolkonskij Thanks for sharing. I will look into it and get one (or two :-)

This is great news. Glad to see such a vital project for retro-computing continue to improve and evolve. It's time for me to get an internal BlueSCSI for my PowerCenter Pro.

I'm currently trying to eliminate the freezes that occur with the Wi-Fi version and always happen when the Mac is no longer connected to the network. This has already cost me several instances of data loss. Currently, I can reproduce or "disable" the crash, but only manually by modifying code in RAM. A test using an INIT failed because it loads too early. Is there somebody out there with Crashes?

As you know, I'm affected on my IIci as well. Though I don't get any freezes while running, it only happens that the Finder will lock up when I hit the shut down command. I need to force quit Finder for 2-3 times before it'll actually proceed with a clean shut down. I know it's BlueSCSI / drivers related because I don't get these problems if I take it out and run it with a SCSI2SD or an original HDD. It feels like the active network connection keeps it from shutting down. I can't believe it is only the two of us suffering from this problem. Since you're investigating, would you please share some of your findings with us as to what could be the culprit? Talk tech to us, pleeeaaassee :-)

The problem is: The system runs fine as long as you’re not on the Internet. Once you’re online, it works too, as long as you stay online. The problems start when you stop generating network traffic. For me, the Mac eventually stopped responding to mouse clicks or completely ignored 'Shutdown' or 'Reboot.' Well, because of that (somehow I have to reboot), I lost two entire partitions—they got totally wrecked. That’s why I installed MacsBug—basically just so I can restart with 'RB.' The SCSI parameters for BlueSCSI (to be entered in the INI) that I gave you did improve things slightly, but the computer still crashes on Reboot/Shutdown. So I’ve now spent three whole days tracking down the culprit. I have to say, this is one reason I don’t want to develop anything on the Mac—you need 100 tools, 100 different things... But back to the problem. I noticed that OpenTransport was always involved during the freeze. So I first neutralized the DaynaPort driver so that it would simply acknowledge the close request with "Ok." That didn’t help. So I kept searching and found out that OpenTransport apparently crashes directly—without the "help" of the SCSI network driver. So I put together a small assembly routine that scans the entire RAM for a specific OT signature and "disables" the code there (CLR.L D0, RTS). In my first test runs, the 475 would still run for 1-2 hours idle after using HotStuff and the browser and could then shut down properly with ShutDown. So I packed the 68K code into an INIT. Unfortunately, the INIT doesn’t take effect because at that moment there’s no OT in RAM yet. If you start the patcher manually, the patch runs through. My question to the pros: In which RAM address (low memory globals) is a)the start of the system zone (here I'm taking the content from 02A6) and where is the end of the memory (right now I'm taking the content from 0114)? Does anyone know when OT is loaded during the boot process? Probably after my INIT - because of course it won't find the signature then. Alternatively: you could probably also push the patcher (not the INIT) into the startup items. I still need a few test runs to be 100% sure the bug is fixed.

I've now moved the patch into the Startup Items folder and completely shut down the computer. Then I did a clean reboot and checked with MacsBug – the patch has already taken effect. Now I'm going to do the stress test using HotStuff, ICab, and then I'll quit the programs, let the Mac run for a bit, and go chop some wood. When I come back, I'll check if it still responds to clicks and then I'll say 'Shut Down.' Let's see.

...looking to the idle 475. Still reacts to Mouse Clicks. Good Sign. Lets wait a little longer, chopping more wood. Then trying ShutDown. We will see, if this Workaround doing its job :-)

Ok,here is the result: Choosing "Shutdown" and.... "Sie können Ihren Computer jetzt ausschalten." (You can switch off your computer now). It seems, there is no lock/freeze anymore.

I just did the counter-test. Started Hotstuff without the patch, closed it - the Mac freezes after about a minute. With the patch (you can also load it while already surfing the web), the computer keeps running. It also restarts or shuts down without any problems. I need volunteers ;-) The patch can also be run multiple times by accident - it doesn’t matter. It doesn’t patch any files on the hard drive, only the RAM.

That sounds very promising! And you know, you've got a volunteer here :-) So the problem really is OT related? Are we talking about OT 1.3 or OT 1.3.1 ?

I am using 1.3, but I think it doesn't matter. In worst case, the Patch cannot find the Module or it will be patched - and this would be ok. I am still writing the docs, the Patch will come with a short Read me, a little hypercard info Stack and some Infos in Form of a word document. And yes, it seems OT related. With a Nubus Ethernet Card, this Problem doesnt exist. Maybe it is also wirh an original SCSI/Link.

I've seen that exact problem. When it happened to me, the system was waiting for something to stop running, and it wouldn't. It only happened to me when I was using an app that used OT.
