HECnet bridge and tun/tap problems on Ubuntu 12.04 ...

by bqt＠softjar.se

Mark, I don't think Bob suggested he used some special program to connect simh to a tap device. What he did was use my bridge to connect his machines to HECnet, which is a step on the other side of the tap device. By the way, Bob, I know that I've seen a patch to simh in the past, to connect to HECnet directly from simh, without the addition of the bridge program. Maybe something to use?

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!

Ersatz-11 PDP-11 emulator V7.0

On Nov 2, 2013, at 2:44 PM, Sampsa Laine <sampsa at mac.com> wrote: Yuk. I would think that a OS interface library might help here. 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
