PDP 11 floppy disk question.

by jim＠g1jbg.co.uk

A simple question, I hope! Can I use a normal 51/4" dsdd floppy drive with an RQDX3, in place of the twin drive RX50 unit? If so, do I need a special cable? Thanks Jim. Please see our website the " Vintage Communication Pages" at WWW.G1JBG.CO.UK

Hi, I picked up an ELL (RS 28-280) at the outlet store. It was cheap because all of the loose parts were missing. I have the base and the books. The PDF file on the RS web site doesn't list things in enough detail to be able to build a list of missing parts. I'm going through the books and trying to tally the required parts, but it's taking hours and I'm likely to make mistakes. Does anyone have one of these and might they have enough time to make a physical inventory? Even a digital picture of the parts spread out on a tabletop would be really helpful.

Xilinx Fans

by aw288＠osfn.org

I know there are a few on the list. I have a card set (mystery custom job) that contains a bunch of FPGAs. Rather than pluck out the Xilinxs and offer them, I am just going to offer the whole shootin match and let YOU pluck the Xilinxs out. (1) 2018-70PC84C (2) 2018-100PC84C (2) 3030-100PC68C (1) 3030-100PC84C (7) 3042-100PC84C All socketted! Unknown condition. The boards also have lots of other oddball parts (soldered in mostly). I will pluck out the three i960 microprocessors, unless someone needs them, as well. Offers plus shipping? Contact me off list. William Donzelli aw288 at osfn.org

RML380Z ROM images

by leeedavison＠yahoo.co.uk

> ps. are 2716's known for failure in this way? Yes, especially if they've been flash photographed. (Ididot photographer killed three of eight EPROMs on a control system card after being told not to use the flash in the equipment room.) Some EPROMS that fail can be reprogrammed, some fail permanently often in blocks. If it was a school machine, or anywhere where it was mostly on, then problems will begin to show after 10 years or so.

I have a vax and a 11/73 using that combo. Allison

Programming 2708's

by rcini＠optonline.net

All: OK, I'm ready to burn a modified copy of the Altair Turnkey Monitor into a 2708 to use in my 8800b as a test program. Lo and behold, my programmer won't do a 2708 -- it'll only go down to 2716. Naturally I don't have any 2716s around and the VG ROM board accepts only the 2704 or 2708 (without modification). So I browsed around eBay and elsewhere to see if any other programmers support the 2708 and it seems that none do. They all start at the 2716. What programmer can I look for that has the ability to program a 2708? Thanks.

My classiccmp non-retirement :-)

by Billy.Pettit＠wdc.com

Jerome Fine wrote: Almost everyone seems to expect that neither a CD-R nor a DVD-R (i.e. the backup media we make for ourselves in single digit numbers) will last less than 20 years and probably less than 10 years. I can't think of any media that might be more reliable. Count me as one does expect CD media, R or stamped, to last longer than 20 years. There will be outlying quality problems from many vendors and for a variety of reasons. But the basic technology yields media that should be good for multiples of 20 years. I've been in the labs in Eindhoven where they can still read some of the original CD prototypes from the mid-70's. As to your second point, about more reliable media: My CDC 160-A still reads some paper tapes that I made in 1963. And I have no trouble playing some of my grandfather's old 78's from the early '30's. A friend in Atlanta has been copying over old wire recordings from the 30-40s time frame. And of course, movies go back into the teens. The point is it is not the media that is always the problem. Sometimes the application sucks. Sometimes the industry use sucks. Everyone has horror stories. Let me add another. Most of the weather data collected from the early satellites has been lost by simple carelessness in storing. Data that would help immensely in building weather models was slowly and very expensively gathered for decades. Then stored in such lousy environments that many of the tapes exist only in a powder form. Decades of data useless because of mickey mouse budget cuts. Millions to gather the data, but pennies to store it. Sellam had the only answer I know: Constantly update your data to the latest media. You normally gain performance, smaller physical size, and greater reliability. And it is faster each iteration. Of course it is expensive and time consuming. But think about the path that many on this list have already taken: paper tape to cards to magnetic tape to hard disks (several generations) to CDs to DVDs to Blu Ray? All of my 160-A software would easily fit on a digital camera memory stick. Billy
