From what I hear, the system I used was not one of the TSB series. I'm still interested in trying it out. I don't see binaries online anywhere. Can someone point me to them? I never did any admin on the systems as a student. I only had access using BASIC. I have booted up SIMH with the hp basic stand alone, and it's similar but lacks some features our system had like string variables. http://oscar.taurus.com/~jeff/2100/hpbasic/basic1.abs I see on jeffs site the source tapes for 22255 "Four user BASIC". Perhaps this is the system we were running? 2 CRTs, one ASR-33 and a card reader would mean 4 users, correct? http://oscar.taurus.com/~jeff/2100/hpbasic/index.html Anyone willing to give be instructions on how to get the files assembled? I would think I'd load something like the "extended assember" via PTR: http://oscar.taurus.com/~jeff/2100/siotapes/extasmb.abs jump someplace? and then feed in each of the basic tapes on the same PTR? My experience has been with Linux on all kinds of hardware, from x86 servers and desktops to alpha, sparc, ia64, mips, ppc, sh3, and many arm systems. Most recent work is with ARM boxes. I was deeply involved with the SHarp Zaurus release while working at Lineo (or Embedix, or Metroworks, or whatever they call themselves now). I have simh up and running. Not the same without the blinking lights. Perhaps Jay's emulator will have blinking lights? We did a version of VNC for the Zaurus that had a "skin" which was a scanned image of the device. I envision the same interface on an emulator. click the buttons with the mouse, turn the key to lock/unlock, Would be nice to have a tape reader with audio and perhaps a mag tape too. ;-) There used to be some internet accessable simh access systems running. Are they still? I notice that simh just loops like the actual machine would. This means it eats up 100% cpu all the time. Seems to me that should get hacked somehow to detect "idle" states, and select() someplace for a short ammount of time instead of looping all the time. If I ran the simulator on my Zaurus it would suck the battery dry in no time. We can't have that can we? ;-) Well, thanx in advance for the help. I look forward to trying out the 4 user basic environment and see if it's what I recall. -- Tim Riker - http://rikers.org/ - TimR at Debian.org Embedded Linux Technologist BZFlag maintainer - http://BZFlag.org/ - for fun!
