So I have an MSV11-QC (the 4gb Q Bus memory board) that has a failed bit. On an 11/73 it throws the following error: Expected data = 125252 (1010 1010 1010 1010 Bad data = 121252 (1010 0010 1010 1010) Address = 10015140 Which puts the error in the top 2mb (1mw), bit 4000. No biggie, consulting the matrix at: https://gunkies.org/wiki/MSV11-Q_QBUS_memory Shows this to be bank 4, bit 4000 or E85. Cut out E85, popped the board in (to double check before replacing) and I see this: Expected data = 125252 Bad data = 121252 Address = 02015140 Ooops. That would be decimal 531,040 which puts it in bank 1? Which should be E88, where did I go wrong here? Or is the table for the MSV11-Q only valid for the 64k ones and not the 256k ones? If so the bits may be right, but the banks are different. Anyone want to cross-check this or my maths? Thanks! CZ PS: Sorry if duplicates are getting sent to the list. I'm retiring cz(a)alembic.crystel.com and replacing it with cz(a)beaker.crystel.com. If the list manager could update my email I would appreciate!

Re: How to print old files.

by Martin Bishop

Ben I think you have the essence of a solution, using the Unix filter paradigm at user or driver level. Your desire to retain the original file format(s) is very sensible, it is always best to record "raw" data - for the greatest fidelity. The ISO 7-layer model provides a paradigm for data transport/storage formats and derived (presentation) formats.

With the rise of emulators for old machines,I can see text being written with terminal emulation of the orginal i/o devices, but that leaves printing or tranfering text files a problem. JOE could have a REAL - big iron 67, SAM runs windows 2000, TOM has a micro VAX. Every thing gets dumped to the cloud. One must keep data as files, none of this crappy mess that this modern 'buy a app' to print,or read. How does one share binary and paper tape/cards as files? Ben. PS: Back to inventing big iron 67. tag line: Cloud computing delayed to to bad weather, server is under 3 feet of snow.

Debugging possible RAM faults on OCC1

by Steve Platz

I recently got an Osborne 1a, which needed a lot of cleaning and had probably been stored in a barn for some time. After getting the drive parts to move freely again and removing a blown cap on the power supply, the machine will start up and the screen is green, although it's just showing some random characters. I understand from someone's advice that some RAM may have gone bad. At this point I'm not sure if I should continue to try to get this going, or just resign it to someone with better resources for diagnosing the issues. If anyone has some advice for moving forward with this, I'd be interested to listen. Some context: this is my first such restoration endeavor.

The programmer believes he has a copy of the source code for PDP-11 and VAX on a CDROM that is in a storage unit.

Saturn-Calc

by Nigel Johnson Ham

Hi all, My 11/73 restoration has got to the point that I am loading stuff from RT11 backups, and I have a lot of Saturn-calc and wp data that I would like to see again. My licensed copy and the manual are long gone! I downloaded some RX02 images posted by Mark Matlock, but the disks appear to be all zeroes where I expect the directory to be. Does anybody know of a source? cheers, Nigel -- Nigel Johnson, MSc., MIEEE, MCSE VE3ID/G4AJQ/VA3MCU Amateur Radio, the origin of the open-source concept! Skype: TILBURY2591

Manual for MDB MLSI-LP11

by Nigel Johnson Ham

My re-build of a BA23 11/73 system continues. I have one of these MDB printer controllers but cannot make it do anything more that home page on the laser using RT-11 Does anybody have a manual or know where I can download one. An extensive search using google just brings up a data sheet. Happy New Year to all, Nigel -- Nigel Johnson, MSc., MIEEE, MCSE VE3ID/G4AJQ/VA3MCU Amateur Radio, the origin of the open-source concept!

SGI vs. Mac

by skogkatt007＠yahoo.com

An Indy for instance, is it much faster then a similarly clocked PowerMac? What about an Indigo 2 IMPACT 10000. Does that blow most PMs away? Anyone using an I2 or Indy with regularity? I have a purple box somewhere. I foumd the teal boxes much more visually appealing.

I had a licensed copy many years ago for RSX11M but it no longer works. I do have a working copy of Saturn-Calc and Graph (but not WP) for VMS on my MV3100-80 but not the VMS distribution. I have managed to contact the lead programmer that developed Saturn’s software through a former president of the company. The programmer believes he has a copy of the source code for PDP-11 and VAX on a CDROM that is in a storage unit. He has retired overseas and come back home where the storage unit is a couple times a year and I’m hoping he can find the CDROM on his next trip back. I can keep you posted on our progress in trying to recover this software. It helps that the programmer is interested in making the Saturn products available as it may need to be recompiled or at least relinked to be compatible with the newest versions of PDP-11 operating systems with Y2K etc. We thought we had it recovered a couple years ago when nine RX50 floppies were found in Australia that were from a distributor that could be used to generate new customer distributions, but there was no documentation and some info was missing. Also, manuals for the Saturn products have not been scanned so we are looking for them as well. If you had some specific Saturn Calc spreadsheets that you wanted data extracted from, I might be able to help you with my working VMS version of Calc. Saturn Calc was a great product that we used a great deal back in the day. The Saturn Graph product supported VT340s with the mouse and could generate plots a wide variety of HP and other plotters, printers, etc. Best Regards, Mark
