SIMMs and other memory dongles (was: Common items you passed up that turned rare when you wanted them)

by legalize＠xmission.com

As usual... come up with an idea and someone else has already done it! :-) (Which is good in this case as I don't want to design, test and build these things) <http://www.homestead-products.com/simtree.htm> -- "The Direct3D Graphics Pipeline"-- code samples, sample chapter, FAQ: <http://www.xmission.com/~legalize/book/> Pilgrimage: Utah's annual demoparty <http://pilgrimage.scene.org>

I wonder how hard it would be to transplant a more modern DRAM chip onto an old SIMM? Lee.

RL01 imaging

> Vince Slyngstad just pointed out to me that there's a TU-58 (DECtape) > emulator that runs on a PC and can be used to transfer data in/out of > a PDP-11 to a modern PC. > Supposedly this is just connecting the PC to a serial port. However, > on my PDP-11/03, I only know about the serial ports for the console > and line printer options. Where is the serial port for the TU-58? I've been using Will Kranz's TU-58 emulator to do just this sort of thing, making images of 5 diskpacks that were included in a recent 11/23+ acquisition. Use a null-modem cable between the second serial port on the CPU (LPS port) and connect it to your PC's serial port. You might need a 25pin-to-9pin adapter, but it's just a standard null-modem cable in any case. On my 11/23+ the LPS port is set for 9600 (which I think was pretty standard), but I could go to 19.2K with some jumper changes that I haven't got the nerve to try yet. Your system might already be set to a higher speed. Experiment a little and you'll figure it out, or physically examine the CPU board. In any case, using such a slow speed for transfering 5MB or 10MB images definitely takes a while, but it is also definitely worth doing. You want to preserve that diskpack image! At 9600 a 5MB disk will take just shy of 2 hours. Check out Will's TU-58 emulator page at http://www.fpns.net/willy/pdp11/tu58-emu.htm J.

Id this IC?

by rigdonj＠cfl.rr.com

Does anyone have any idea what this IC is? <http://www.classiccmp.org/hp/Unknown%20IC/Unk%20IC.jpg> This is the second one that I've found but I haven't been able to find any information on it. Not even who made it. It's a standard .3" wide 16-pinDIP and it's marked PX032768 (9003) and it has a small window on one end. Inside the window is what looks like a tiny tuning fork or something. Any ideas? Joe

Road Trips

by brian＠quarterbyte.com

> WOW! 3100 miles... that's like the max that you could do in the > states. Did you get the system in Maine and drive it to San > Diego? Close -- Canton, MA to Oakland, CA. Mapquest calls it 3113 miles, but we took a couple of short side trips in western MA, so our trip may just edge out Vinces's Beaverton, OR to Gloucester, MA roundtrip. Besides, we had a 28' truck, not a poofy little van :) (And, hmm, Key West, FL to Blaine, WA seems to be the longest driving distance in the contiguous 48 states, over 3600 miles. Are any longer shortest-path trips possible entirely within one country? Looks like Canada, Russia and China have longer ones, and maybe Chile). The major geek factor during the drive was maintaining a spreadsheet that calculated our arrival time in Salt Lake City, factoring in waypoint distances, driving speed, rest stops and sleep times, which we used to ensure we'd make it to the Red Iguana restaurant for dinner before it closed. It turned out we were only allowed three hours of sleep in Nebraska, but it worked. Left MA on Thursday evening, and made it to SLC on Sunday night with two hours to spare. (Why? Seven reasons: mole coloradito, mole amarillo, mole negro, mole poblano, mole pipian, mole verde, and mole de almendras -- worth a trip to Utah just to eat there, but this drifting off topic, isn't it.). Made it home to Oakland Monday night. > When do we get to see the pictures?! We should have some pictures of the Sunshine Biscuit Factory remodel and the system up on ibm1130.org or maybe another site (as we have everything but the 1130 there) sometime soon; we'll make an announcement when it happens.

Id this IC?

by dwight.elvey＠amd.com

Hi Joe I think that is a clock chip. It is for low frequency, like 32KHz. I think I've seen these someplace but don't recall where. Why it has a window I don't know but it might be for laser fine tuning.
