I provided a :SOO UDC that runs one of the several variants on the system from various CSL releases (that actually works on this MPE version).


And even better, the system has OPT, which is just an amazing piece of software as the last version from MPE/V still works great on our V/R (which is really MPE IV even). OPT quite happily displays the 8MB worth of memory banks, 4,000+ I/Os per second etc. It will also show you system table usage graphically or numerically.


You'll need an actual HP terminal emulator connected via telnet to run it, however.


A working copy of IDAT[4] from telesup could be nice to have, though the one incompatibility from running with >2MB of memory is that the memory dump format written by the Series III stuffs the current DB, S, and P bank numbers into a single 16-bit word so there's no way to fit 18-bits worth in there, which may well limit your ability to successfully analyze a dump produced on the system if it's using memory beyond the first two MB at the time of the crash. It would probably be possible to change things to use the Series 64 dump format, but then that might confuse some analysis tools.


I had forgotten about PEEKABOO also. I looked around and don't see it anywhere. IIRC, it may have only worked on ATC ports on a Series II/III or at least wasn't commonly available on the HP-IB systems so it may be pretty rare as collectibles go.


MPE V/R only has the original Image, not even TurboImage, so I'm not sure there's an easy path backwards from a modern TI database, which is to say you would need to UNLOAD it on a (more) modern system and then rebuild it under MPE V/R, assuming it would fit within the older config limits. Most of the databases that are included on the system from CSL contributions are not usable as a result.


Ultimately, people would like to be able to emulate newer HP-IB hardware and run true MPE V/E, but we currently lack the low-level of hardware documentation that would be required to do it without a lot of work. The same thing applies to networking, where the details of things like the INP and HP-IB Lanic have never been available (they also came from a different division and their source code was much harder to come by). So, for now, the dreams of having a DS network of Series III systems remains just that.


I'm on the lookout for copies of Business Report Writer and Business Basic, which I want to see if I can get to run under MPE V/R even though that was never officially supported.

Cool stuff, thanks Gavin.

Does anyone have a copy of the TELESUP account?


Remember SOO?   Son Of Overlord.

What did we used to look at system tables?  

Also I found the source for DSWHO, anyone remember John Rutdledge?

I notice I keep on forgetting to type the RUN command.
