This just came up on Fess Bouc. I did not know that it existed. It's an LLVM-backed modern compiler for BLISS. https://madisongh.github.io/blissc/ -- Liam Proven - Profile: https://about.me/liamproven Email: lproven at cix.co.uk - Google Mail/Hangouts/Plus: lproven at gmail.com Twitter/Facebook/Flickr: lproven - Skype/LinkedIn: liamproven UK: +44 7939-087884 - ?R (+ WhatsApp/Telegram/Signal): +420 702 829 053

Hello, do you know the people who made the video? I think the factory is the Satilai in Saronno. Andrea

M7264 Troubleshooting

by vintagecomputersmn＠gmail.com

I took a look at all the lines you mentioned. BDAL3-13, BDIN, BSYNC, and BBS7 are all active and jump around in some manner. BRPLY is still the only line that does not have any activity on it. None of the BDAL lines seem shorted to ground or to each other. My DLV11-J is configured to essentially factory settings (J3 set as console, 8 bits no parity) except for the fact that J3 is at 9.6k baud instead of 300, the address jumpers are exactly the same as the one you provided.

11/93 Rebuild

by rodsmallwood52＠btinternet.com

Hi ????? Thanks to Glen Slick I now have a old windows xp system running SIMH ???? Its connected to my LAN so web and file access are OK ???? In addition to the normal IDE drive it has an additional SCSI controller and drive ????? Using SIMH? I have created an image (RD54.dsk) containing a RSTS system. ???? I am awaiting the final instructions as to how to copy the image to the SCSI drive in such a way I can connect it to the SCSI controller in the 11/93 and have it boot. Rod Smallwood --

HP/UX 8 and hosts vs DNS

by spectre＠floodgap.com

I've been doing more work on my 9000/350 now that I have actual space to do work on it in. Although the 10b2 is flaky, I can usually coax it to work. However, the damn thing won't query DNS even though I have a populated /etc/resolv.conf. It can ping the name server, and if the name server's name is in /etc/hosts it will resolve it (and even telnet to it), but it won't talk to it for anything else. I'm not as adept at HP/UX before 10.20 (my first experience with the OS), but I understand 8.0 "fails over" to /etc/hosts if it has some issues with DNS. Fine, but how can I get it to switch *back*? There's no /etc/nsswitch.conf and I don't think this version supports it anyway. -- ------------------------------------ personal: http://www.cameronkaiser.com/ -- Cameron Kaiser * Floodgap Systems * www.floodgap.com * ckaiser at floodgap.com -- There is always one more imbecile than you counted on. ---------------------

11/93 rebuild - Project Suspended - PC died

by rodsmallwood52＠btinternet.com

The Acer PC I was using to write the image to the SCSI drive has gone kaput. Clearly PSU (not plugtop? mains fuse). Its a non standard PSU and no schematic available. Fall back is to get one of the SLU's (other than the console) on the KDJ11-E going and TU58 it. Rod --

Abandoned FACOM system in Italy?

by evanlinwood＠hotmail.com

I'm guessing this could be known to others on the list, but I haven't seen it mentioned, so posting just in case. There doesn't seem to be mention of any recovery effort in the comments (that I could see). The most interesting section is from 14:14: https://www.youtube.com/watch?v=rrx1tK5xcAk [https://www.bing.com/th?id=OVP.nmj3ysj3FfGgc8gP7yLUrAEsDh&pid=Api]<https://www.youtube.com/watch?v=rrx1tK5xcAk> Huge Abandoned Clothing Factory - Found Vintage Computers!<https://www.youtube.com/watch?v=rrx1tK5xcAk> Go to https://NordVPN.com/properpeople and or use code PROPERPEOPLE to to get 75% off a 3 year plan.

11/93 rebuild

by rodsmallwood52＠btinternet.com

Hi ??? Whilst I wait to hear from Glen Slick who has got me this far (Thanks Glen) I'll restate the problem. 1. I now have an old XP system with SIMH on it (PDP11.exe) 2.? I have created RD54.dsk containing RSTS/E 3. Attached to the system is a 2.1Gb SCSI drive via an adaptec 2940 controller 4. I need a tried and tested list of step by step instructions to put RD54.dsk on the SCSI drive. 5. The drive will then be moved to a CQD-220A/TM SCSI controller on my KDJ11-E based 11/93 and must boot. 6. Its just an image copy from one drive to another on the same system. 7. Nobody has come up with a tried and tested list of step by step instructions yet. Rod Smallwood --
