Yes. I later did try a copy from high-level VMS. The same issue was present there...but it actually got somewhere almost. ;) If I'm understanding you right then it sounds as if the controller may indeed be storing its own stuff in the first block(s) and the partition for DU1: isn't supposed to start until a few blocks into the drive. I would experiment with that by zeroing the disk, and then partitioning it on the PDP-11 (I assume this is done with the SCSI controller's firmware), move it to the PC and pull off the first few blocks, then repeat the process with different partitioning (assuming that's possible -- or do you mean the firmware is hard-coded to split drives into chunks .LE. 512 MB?), and see what changes in those first few blocks. It might be very obvious... It seems to split the drive in to 2 or 4 partitions. I can't manually define partition size...I am also having the controller identify the drive to the OS as an RA82. That could also be my problem. It's ~2.1G unpartitioned. Another thing to do is generate a bunch of different boot blocks that look like this: .word 240 ;NOP (required by some boot PROMs) .word 0 ;HALT (unless the PROM also requires a BR ...) .word blkno ;block # you'll be writing this one to .blkw 253. ;(junk for the rest of the block) ... and copy them to the first N blocks of the SCSI disk. Then when you move it to the PDP-11 and boot from it, it'll halt, and if you examine the word at 000004, you'll know which actual block was read in as block 0. Then next time write your image starting at that block instead of 0, and it might work. That would be a good debug routine. It boots RT-11 and RSX-11 fine, though. If you wanted to get *really* fancy, maybe you could set up a Linux (etc.) box as a SCSI target, and log the actual block #s accessed by the PDP-11? Seems kind of ridiculous... Yup. Just a bit. ;) John Wilson D Bit -- Cory Smelosky http://gewt.net Personal stuff http://gimme-sympathy.org Projects

I guess that s true, but it doesn t seem to cause trouble. I do a lot of my personal Unix development on Mac OS with few issues, other than having to put up with Clang. For example, SIMH works just fine. paul

RSTS/E is really picky

From: Cory Smelosky <b4 at gewt.net> The disk is 1048778 blocks. I created a 512M image and copied it bit-for-bit to the disk. So you're saying the image *did* work under emulation and only broke when you copied it to the first 512 MB of a disk that you then moved to a controller with an unknown private partitioning scheme?

I was the operator of nodes 10.1 (SHARK) and 10.2 (SNAKE) until I had to reorganize (== shrink) my server facility and flip the HECNET switch off on July 2010. SHARK and SNAKE have resurrected from 4 years in limbo, thanks to VirtualBox. They are PDP's running 11M+. I even discovered a forgotten 10.3 (SQUID), with sysgened PC11 to spool data from/to Unix pipes. That was the opportunity to check HECNET community health, and I am pleased to see it is in great form. This list is one of the more active I subscribe to. I was surprised to see 10.1 and 10.2 in MADAME's nodes table. Is this for real? I thought they had been purged or reassigned for long. Virtualization had the side effect to move simh from Mac OS X to Linux, and things are much more simpler and up-to-date (Apple don't care BSD besides its own needs). I am now trying to install DECNET for Linux. This will allow to move large sound files from the ancient world to the present. -- Jean-Yves Bernier

The item shown is just the interface box. The Pro 300 series Technical Manual describes the whole system it consists of three parts, the one shown in the Ebay entry is one of the three the Voice unit , which is basically a speakerphone box with some extra buttons on it that the software can see. Not clear if the other two parts, which are the important ones, are included in the offer. paul On May 20, 2014, at 1:04 PM, lee.gleason at comcast.net wrote: If anyone out there is hankering to have one, a DEC PRO telephone Voice Unit is on Ebay right now. http://www.ebay.com/itm/NASA-Digital-DEC-DTC11-B-Voice-Unit-Professional-30…

Of course... :-( Anyway, I just realized/remembered that I'm not sure if the PRO was ever mentioned in the context of PDP-11 with graphics and sound. The PRO obviously always have grahpics. But there was also a sound option to it, which could interface with telephone systems. Not sure exactly how capable it was, but I have some blurb in a handbook somewhere. Johnny
