Was CP/M in ROM on the VT180? Nope, booted from 5.25" floppy from an RX180 disk subsystem.

RSTS/E + DECNET 4.1

Whoops, I remembered last night that the technique of generating a PAKGEN license wouldn't work with the Macro-32 file I sent you. That was a different licensing hack. I think I had patched LMF.EXE to generate my own licenses once upon a time. But, that was ages ago. --Marc

embedded libraries for PDP-11, was Re: [HECnet] DECUS RSX C compiler

El 22/10/2012, a les 21:32, Dave McGuire <mcguire at neurotica.com> va escriure: The 2.11BSD lib looks leaner, and I am using it in my pet OS project (I pick the pieces I need "on the run", I have not done a complete port... yet). If the above suggestion doesn't get you anywhere, perhaps avrlibc could be hacked into a PDP-11 library. All of the hardware support will have to be ripped out of course, but there are nice tight implementations of generic library functions in there Doing an unrelated search, I've found this: http://pdclib.e43.eu I have to take a closer look, but it seems promising.

Dump them all in a format we'll all be able to read in a few years and store it on say, amazon glacier. Who would want anything less than advertised eleven nines for storing email? I dunno, I'd want something more than storing it on someone else's hardware. Especially when that someone else is a huge corporation, subject to corporate whims. Your data could go away at any time. Well, We are running a network of computers... It would seem to me it would make way more sense to have such an archive available on our computers... Johnny

I expected this mailing list to be less helpful with regards to my noob questions, I was pleasantly surprised. I've learned quite a bit from this mailing list in a short while. ;) On that note, we really should be archiving this stuff. I think I've got most mails going back a few years in my inbox still (I don't believe in folders, that's why search was invented). I probably have everything, but it's mixed with personal messages to me related to HECnet as well, so it would take a little work to clean it up for access. Johnny

I found a bit of a "guide" but couldn't get it working in simh, could prove challenging to get the files to real disks though. -Dave -- Dave McGuire, AK4HZ New Kensington, PA Hello! Don't laugh folks. At one point I actually wanted an LSI-11 here to work with. Then I ran out of space.... Now I'm interested in this thing: Models without standard bus PDT-11/150 PDT-11/110 PDT-11/130 PDT-11/150 The PDT series were desktop systems marketed as "smart terminals". The /110 and /130 were housed in a VT100 terminal enclosure. The /150 was housed in a table-top unit which included two 8 inch floppy drives, three asynchronous serial ports, one printer port, one modem port and one synchronous serial port and required an external terminal. All three employed the same chipset as used on the LSI-11/03 and LSI-11/2 in four "microm"s. There was an option which combined two of the microms into one dual carrier, freeing one socket for an EIS/FIS chip. The /150 in combination with a VT105 terminal was also sold as MiniMINC, a budget version of the MINC-11. I abstracted the text from this Wikipedia page http://en.wikipedia.org/wiki/PDP-11 . I figured that of all of the machines we know that one is least well known. I'm not sure what I can do with any of them, but I certainly hope I could manage something appropriate to what we are discussing. Incidentally Dave I'm still waiting. Outside your place are a van of frustrated yetis and related individuals in a brown van who're waiting and watching. You can alternatively look for a VT103 as well, since that is pretty much the same thing as a PDT-11/130. If you do some wiring on the Qbus backplane, you can do 22-bit. Throw in an 11/93 CPU, SCSI and what else, and you'll have an awesome system in a VT100 body. Johnny

Oh, c'mon. There is plenty of real hardware on HECnet... Including some really big iron. :-) Johnny On 2012-10-30 04:24, Sampsa Laine wrote: Is this a node on HECnet BTW?

I have a feeling you'd want something more valuable than an iPad 2 + bluetooth keyboardcase. ;) Perhaps not...are you looking to unload the iPad? I'd hook you up with a sweet system for that. Yeah, I'll part with the iPad. Don't have much use for it now save for as a musical instrument. I can include 2 keyboards, one docked and one Bluetooth. 2 cases as well, keyboard is built in to one of them. Wall charger and sync cable included. Hell, I still have the box... Hmmm. Ok. Let's take this off-list. (tomorrow...about to crash here) Yeah, okay. Tomorrow. Have any interest in a USB/eSATA SATA drive dock? Nope. Unfortunately, all that remains is the keyboard and processor. And 6G of laptop DDR3. It was a fairly broken laptop. I /might/ still have the display, too. That's, umm, not terribly useful. ;) What happened to it?? It had several issues. The power system was touchy...it would be fine for months, then it would sometimes endlessly turn itself on and off (for a better description I'd need to consult logs...it's been awhile), graphics would glitch, disc drive loved oftentimes not working, it couldn't boot from USB CDROM. It couldn't do hardware-assisted virt, the NIC might not have been GigE, short battery life. It wasn't very old either... Even more amusing? It was a product model that did not exist. The model did not appear on the manufacturer's website. So I scrapped it for useful parts. -Dave -- Dave McGuire, AK4HZ New Kensington, PA
