Kuiper/Charon X3.1, Platform: Takara @ 500MHz, MOS Operator Control ???

by mark＠wickensonline.co.uk

So the latest Takara Alpha PICMG Industrial PC picked up from eBay last week has a different firmware image to the last one. Apparently it has something to do with VNswitches, but I'm not sure how it would have fitted in to a bigger picture. It looks like at one point it contained three network cards given the errors. Does anyone have any knowledge of this? It looks like I'm going to have to resort to the technique I performed on the last box when I flashed AlphaBIOS which would then not allow a reflash. I had to set a jumper on the CPU card and create a boot floppy with replacement firmware on. Looks like the 'MOS Operator Control' prompt is a dead sheriff rather than a dead sergeant!

It works and gets the job done for what I have to do with it. wxWidgets also looks pretty useful also. Clem

Linux, Mac OS and *BSD are all pretty much the same for the basic I/O and all three support most of the basic low level OS stuff from open/close/read/write to mmap/semphores etc.. Where they differ is in UI and specifically GUI. I wonder if you considered something like QT for everything but DOS, I would like the amount of OS specific code you had to deal with I would hope would drop substantially. QT would look like ass, frankly, esp on OS X. I'd go for SDL and just make the UI a framebuffer thats a DOS screen with the same inputs as the DOS version. No need to write any manuals either :) Or SDL and a Star Trek interface or whatever, but all the cross-platform GUI stuff looks TERRIBLE on OS X. Maybe Qt does -- I only looked at it briefly and concluded I liked neither the API nor the license. However, wxWidgets works very well. It's very portable, produces native looking applications, and works on lots of operating systems. I've been using it for years. It also comes with a good Python library. paul

I really would like to attack the *BSDs ... I investigate periodically but I just can't decide which I'd regret more: conditionalizing the hell out of 11K lines of Linux-specific support code, or editing a copy into ~11K lines of BSD-specific code that's easy reading but needs to be maintained in parallel. Um, or I could do both? Nah. It would be fun to get working though. John Wilson D Bit

John, When would the demo (available via telnet) be accessible again? What are, besides the duration limit, the differences between the demo and the full version?

What are you talking about? The replacement for Mac OS work started long before Jobs returned. You are right, what they ended up with NextStep/OpenStep etc. But learning to join what we now call the FOSS community began before he returned. Talking to my friends that were there at the time, the tell me that culturally breaking out of the "closed" nature was not something Jobs liked. The engineers inside Apple at the time were what started it. Remember then they were still in the Avis "we try harder" mode to Microsoft and the PC and many of them felt the way to fight redmond was to be part of the unix community etc.. When Jobs returned, they were already participating in the FOSS community. There was a system called MachTen the pre-dated the Next machine ( IIRC that was being used inside of Apple before NextStep also). I ran it on a 68030 based color Mac-II (which I only go rid of about 2 years ago). It was CMU Mach/BSD under the covers and allowed traditional MacOS programs to run. A lot of folks thought it was cool - best of both worlds. Also your comment about App store -- I ask you to please differentiate between the iOS App store and Mac App store, Many Mac developers that I work with do not use the later and I know some are proud of it and display thing on their web sites saying so. If I look at the system in which I am typing this message, very few of the applications come from the Apple store. That said -- I agree with your comment for iOS however and nearly 100% of my iPhone apps come from the store. All do indirectly[the IT shop of my employer loads a program from the store called "apps at work" - and that program some how loads other applications from an Intel specific library]. IMO, with the success of iOS, Apple seems to have gone back to its closed ways and I do find that worrisome. Clem
