Hello, Please add to the HECnet nodelist: 7.79 BITXT0 TOPS-20(PANDA) - KLH10 - Raspbery Pi I am running this simulator in the same Pi which currently holds 5 more VMs. I will see if it keeps stable, and if it does I will run it permanently. Issues to solve - KLH10 does not idle in the Pi. I'll check the idler device code to see if I can guess what is happening. - I tried to give KLH10 its own bridge device, plugged into the rest of my network via VDE switches and plugs, but it does not work. I have lots of IPBLP bugchecks and IP networking is unusable (weird enough, DECNET and LAT seem to work). It works fine if I use the main host interface in non-exclusive mode (but then I don't get LAT). - KLH10 frontend can't load *.EXE files. - TOPS-10 does not run well. I used a x86 KLH to dump the load code in SAV format and then I can boot TOPS-10, but it hungs after a while. On the other hand, I'm thinking about building a blinkenlights device using the GPIO pins of the Rasp-pi basing it on the actual parallel port blinkenlights panel driven by the "lites" device... :) It could be another nice hobby project...

Anyone running KLH10 in the Raspberry Pi?

by tim＠sneddon.id.au

Hi Jordi, Have you tried running the DEC-10 diagnostics? I'm not a -10 guy's as such, so I might be wrong here, but I think they are called the KLAD pack. Search for KLAD on http://pdp-10.trailing-edge.com/. It should be much easier to pin point which part of the microcode is causing the problems. Regards, Tim.

For some reason it does not set up the initial address (but probably the problem is beyond that). I have been able to dump from a KLH10 running in a amd64 linux to a *.sav file and it seems to work... but then it does not recognize the TOPS-10 structures. I will work on both the LOAD problem and the disk problem a little bit. - TOPS-20 (PANDA) does boot, but the networking code does some weird things. Basically, lots of "***BUGCHK IPIBLP*** IPNI input buffer list problem" messages whenever I try to do something with IP networking. I have googled for that bugcheck, and it is related to the system being able to get IP buffers when it needs them. It could be a race condition, or some weird thing related to default word sizes. I'll keep trying... :) Jordi Guillaumes i Pons jg at jordi.guillaumes.name HECnet: BITXOV::JGUILLAUMES

Largest PATA drive that a DS10 can use?

by Alastair.Boyanich＠au.fujitsu.com

Yep. 40 vs 48bit addressing. Need it on the controller. Your right. Al. -----Original Message----- From: owner-hecnet at Update.UU.SE [mailto:owner-hecnet at Update.UU.SE] On Behalf Of Marc Chametzky Sent: Friday, 30 November 2012 4:44 AM To: hecnet at Update.UU.SE Cc: sampsa at mac.com Subject: Re: [HECnet] Largest PATA drive that a DS10 can use? So it's basically maxed out as far as IDE goes? Isn't there a 137 GB limit to older IDE controllers? I don't remember much about the various IDE restrictions, but that number pops out in my head and it's likely that the older DS10 might not have the necessary support for larger drives. --Marc

I've got a pair of u320 300gb SCA's on a converters in a TS10. Works fine thus far and I've filled and tested it. Don't know about the PATA .. it's stinky ALI afair.

DS10 and the Alpha/PC family for sure but IIRC, most, if not all them. The original satellite DB stunt was done by folks in our team that were on site at MSFT. They did the work with SQLserver on a Turbolaser - so at least that had to work somehow. At the time, MSFT was trying to show that it could scale up to big systems. I have no idea if DEC ever sold any of these or what the NT/Alpha SPD officially stated.

Speaking of NT on Alpha, does HECnet have any Alphas running NT? If not, which alphas did NT support? I might try to bring up NT/alpha in a VM. Furthuremore, it's not in any SPD that I know of, but Tru64 will recognize and boot from an Adaptec controller -- the DS10 in my office MRO did just that. IIRC: VMS will work with an Adaptec but can not boot off it.

Uhh..."supported" and "will work" are often two very different things in DECland. I wouldn't consider a documentation quote very authoritative here at all. That said, the DS10 is a fairly late-model Alpha, introduced in 1999. I'd expect it to at least support 28-bit LBA, topping out at ~137GB, but it may support 48-bit LBA (BIG). I don't recall ever having used a drive larger than 120GB on a DS10. Of course for SCSI, the real limit may be much higher. There are lots of ways to get big storage on a PCI-based Alpha. -Dave -- Dave McGuire, AK4HZ New Kensington, PA
