Freeware CDs Available for RSX-11 and RT-11

by jhfinepw4z＠compsys.to

In regard to the Freeware CDs for RSX-11 and RT-11 that Tim Shoppa originally produced: I am in the middle of making up a second (very small) batch of CDs and could easily add a few additional copies. I will be making all copies of the CD images from: ftp://ftp.trailing-edge.com/pub/cd-images/ http://www.classiccmp.org/PDP-11/RT-11/ http://www.classiccmp.org/PDP-11/RSX-11/ Since not everyone has both a high speed internet connection and a CD burner, I thought it would be helpful to make them available. If you have both requirements and are using Windows 98 SE / Nero Burning, I can help with the details if you don't know how to burn a CD from an "Image File". I have even been able to produce a label for each CD that is close to the original label from Tim Shoppa, although since they were scanned (THANK YOU FOR THE HELP), they are not perfect. They are available at $ 5 / $ 9 / $ 12 for 1 / 2 / 3 CDs. In addition, I understand that Memorex Black CD-Rs have a longer shelf life and are available at Business Depot. If anyone wants those instead, add $ 1 for each CD that you are requesting. Thus those amounts are $ 6 / $ 11 / $ 15 I will be picking up some Memorx CD-R blanks in a few days and starting on the copies for those who have already requested that a Black CD-R be used. Please include your mailing address!!!!!!!!!!!!!!!!!!! In general, I will regard any funds you send as a gift so that if anyone really can't afford the CDs, please state why that is so. Outside of the US, probably about $ 2 should be sufficient for extra postage. All amounts are in US dollars. Please ask if you are not in the US. No point in converting twice. Sincerely yours, Jerome Fine -- If you attempted to send a reply and the original e-mail address has been discontinued due a high volume of junk e-mail, then the semi-permanent e-mail address can be obtained by replacing the four characters preceding the 'at' with the four digits of the current year.

PCjr and SCSI - ?

by nampcjr＠yahoo.com

I recently made a good purchase on some PCjr stuff that includes a SCSI sidecar made by PC Enterprises....This was neat not only for the fact that you could hook a HDD up to the Pcjr, but it was bootable as well! I have heard of other ways to hook the PCjr up to SCSI devices other than through the PCE sidecar (TMC 850jr) and have even heard roumors.....they were bootable as well...This would have taken some clever programming and the addition of EPROM's...etc...Im wondering if anyone out here ever had such a project going, completed and would like to share the knowledge of the "How-to" Brian

J-11/PDP-11 - Litton Industrial Automation Systems MPC-II Microcontroller

by ken＠seefried.com

I've found what might (or might not) be a real treasure, a pair of Litton Industrial Automation Systems MPC-II Microcontrollers. These are J-11 based industrial controllers, that include among other things video from a Motorols 6845 CRTC. I'm looking for any information I can collect about this thing. More info at http://seefried.com/kjs3/nerd/whatisit/mpcii.htm. Thanks... Ken

Troubleshooting lockup problems

by d_cymbal＠hotmail.com

Hello All, I'm looking for pointers on how to troubleshoot an apparent hardware problem with an Atari 400. The machine runs fine for about 5-10 minutes and then will lock up solid. Turn it off, leave it off for a bit, and get another 5-10 minutes so I'm assuming that there is some sort of heat/temperature issue that is causing it, but I'd appreciate any tips on how I can drill down further to determine the exact cause. Thanks much. dc

Free, if you want 'em

by avickers＠solutionengineers.com

Just had a bit of a clear-out of one of my cupboards, and came across some elderly Intel type stuff which someone may find useful. All untested, as I have nothing to test them on (no, that's the truth!). All items are free if you send me a padded SAE, or £1.50 (UK) if I have to provide the envelope & postage. Items available are: 1x 386DX20 CPU 1x 387DX20 to match above 1x Cyrix 6x86 P150 CPU 4x 30-pin SIMMs, 1 pair & 2 singles, IIRC 1MB each. All items were working when I pulled them, but have sat in a box for so long now that I couldn't honestly say whether or not they still do. The next stop for these is the bin, so grab 'em now if you want 'em. -- Cheers, Ade. Be where it's at, B-Racing! http://b-racing.com

STAR TREK: THE SEARCH FOR POWER

by marvin＠rain.org

I just received this in email, and thought this might be interesting to the listmembers! ********** "Sulu, set XR4 to CPM, and install the ExtRAM. We're taking her out." "Aye, sir." "Scotty, how long until we can shift into Linux?" "Captain, if you can install the bubble memory, we might have room for Linux and a couple of system utilities. Possibly an application. I think we can do it, but there are too many unknowns. We'll need to do a proper shakedown." "Spock?" "Linux is a massive system, Captain. It may be more than we can handle." "Sulu, compile the Linux kernel, and load it from the cassette drive." "Cassette drive? ......Aye, Captain." "Scotty, I want full power to the internal modem and to the PDD2." "Captain, yer overloadin' her as it is. The power supply just isn't built to run the external LEDs." "Power, Scotty! I want more power! Chekov, attach the mouse to the BCR. Spock, any results on the clock speed?" "Fascinating, Captain. It seems as if the modem interrupt is overwriting the background task timing, which is slowing down system performance." "Yes, Bones? What do you want?" "Jim, you just have a little spreadsheet work, mailing labels, and some word processing. Don't you think you're overdoing it a bit?" "Scotty, where is that power!?" "Captain, I'm givin' ye all she's got. It's that miserable printer with the low impedance causing a backward leak through the low-power indicator. You'll have to install a diode to fix the bias if you want to see the true power level." "Chekov, install the half-wave rectifier." "Yes, sir." "Uhura, any word from Club 100?" "Well, Captain, we've received several interrupts from the ring-detect circuit, but, because we're not multitasking, the data is just sitting there." "Sulu?" "Captain, she's shifting into 600 baud Captain, I'm losing control at the helm. It looks like we've encountered a bad sector." "Put it on visual, Sulu." "Captain, the monitor is not responding, sir. Shifting display to LCD mode." "Spock? What's the problem?" "Unknown, Captain. Linux seems to be rerouting all input to a null device." Trying 'grep'", now muttering, "whatever that is." "Scotty, what's happening with those '/dev' subdirectories?" "Captain, she canna take much morrre.... Another fifteen seconds and the NICAD'll burrrn up for surrre...." "Scotty, we're not using the NICAD." "Sorry, Captain, but I haven't been able to say that for twenty minutes." "Uhura, notify Club 100." "Captain, the display cannot keep up with input data past 300 baud." "Spock, install the SWEEP scroll disable." "Yes, sir." "Captain! I'm getting a message from Club 100...... Apparently, sir, they're going to time-warp previously forgotten modes of data handling; it looks like binary data is being received in the input buffer port now." "Scotty, quick, shift TELCOM to Kermit. This could be a trick to get us back to the standard ROM." "Chekov, we need hardcopy! Fire HP LaserJet!" "Aye, sir." "Bones, how do I see which tasks are active?" "I'm a doctor, Jim, not a command shell!" "Scotty! Why can't I get a directory on this thing!!?" "Captain, ye just canna have the X Window System running in 32K of RAM. It's like matter and antimatter, the system's too bogged down. Yer drainin me quartz crystals." "Chekov, report." "Captain, the little arrow is responding, but the status bar shows we're back to 1980." "Spock? What's happening to our multitasking?" "It appears as if the needs of the one are outweighing the needs of the many." "Captain, she's not even runnin on reserve now. We'll have to do a cold boot for surrre." "Bones?" "It's dead, Jim."

IBM 4331 in MA

Worth saving whole. I count about 7 Pickups full but it would be much better to rent a Penske or another full size truck with a Railgate. A standard liftgate might not handle the 1403, IIRC that is 1600 pounds on a wide wheelbase. If you go from Whse loading dock to another loading dock you do not need a liftgate, same if you have a forklift at each end. Having moved something like that I would rent a 26 footer. My quick calculation is 25 1/2 feet. Take packing blankets because the small stuff has to go on top, and rope along with some IBM wire wheel stops to secure the stuff so that it doesn't roll around. In Oregon, USA, you do not need a CDL if you are moving under 26,000 pounds. Here I rented from Ryder for full size trucks or Budget for lighter trucks, never used Penske. Heavy stuff goes in first and up front. The keypunches at the back. I can suggest a loading plan if you get the system. A big problem with IBM is it is heavy and hard to get out of a pickup without a crane and or crushing yourself. The larger truck is priceless. When you use the proper equipment it is easy. Make sure everything is tied down well, that is what the rope is for. Paxton Astoria, OR USA
