Now that I have my 3B2/300 up and running, I'd like to get developer tools installed. Unfortunately, I can't find any of them on the web anywhere. Apparently what I'm looking for are the following packages: * "C Programming Language Utilities" * "Software Generation Utilities" * "Extended Software Generation Utilities" Apparently these three packages are contained on five diskettes. If anyone has these, or can track them down, please let me know! -Seth

Front Panels - PDP-8/e Type A Availablity

by rodsmallwood52＠btinternet.com

Hi Guys I now have a limited quantity of PDP-8/e Type A Front Panels ready to ship. Type A is the early kind where the selector switch runs from the 12 o'clock position anti clockwise to the six o'clock position. If you have a paid order for a Type A then it will ship to-morrow. The others will go in the order that I receive payments via PayPal When they are all gone you go to the top of the list for the next batch. PayPal Payment as follows $150 per panel plus shipping at $20 per panel, You can order more than one but to be fair everybody who orders in time gets one and the rest to follow. Don't worry there will be a new batch of Type A next week. It gets better there will be a Type B release to-morrow. Same rules as above. Same Pricing Even better PDP-8/f and PDP-8/m artwork is complete and panels will be made starting to-morrow. Release 1-2 weeks Rod (Panelman) Smallwood

C & undefined behaviour - was Re: tumble under BSD

It's the latest cretinous-lemming craze in the world of high tech - we _MUST_ hide all our bits in encryption, because otherwise some dastardly, evil government agency will peer at them ... or something like that. Let's all just conveniently ignore the fact that if said government agency/ies _really_ wanted to know what someone was doing online, they'd perhaps infect that machine's bloat-/Swiss-cheese-ware, which passes for contemporary 'best software practices', with a virus that would report every keystroke ... or something like that. Never mind! Everyone turning on mandatory HTTPS on their server, refusing to even deign to talk to you without it, can sleep the oblivious sleep of the morally superior, rigidly secure in the knowledge that they have done their bit in the crucial fight of out time, to protect privacy and human rights. ... Or something like that. Sorry. You pressed one of my hot buttons - one that is connected to several other of my hot buttons. Noel

VR241 Substitute

by robert.jarratt＠ntlworld.com

I could do with getting hold of a VR241, but these seem to be pretty unobtainable. So the alternative is to rig up an adapter of some kind to work with a VGA LCD, which also saves on space. I came across the following: http://www.vcfed.org/forum/showthread.php?38450-VR241-substitute-for-Rainbow -VT240-etc, has anyone else tried this with success? Regards Rob

AT&T 3B2 floppy format

by lists＠loomcom.com

I finally have my own AT&T 3B2/300, and I'm having a heck of a time getting disk images transferred to physical media. I have here a set of AT&T SVR3.2 diskette images, apparently made (not by me) using dd. I would like to transfer them to physical media in such a way that they're usable by the 3B2/300. Here's what I know so far: * 3B2 diskettes are 720KB, Double Sided Quad Density (DSQD) 96tpi * Each side is 80 tracks, 9 sectors per track, 512KB per sector * Sectors use 3:1 interleave * Physical media should be good quality DSDD * The 3B2 fdc is a TMS2797 (WD 2797 compatible) * The 3B2 floppy drive is a CDC 9429 On my PC, I'm using a venerable TEAC FD55-GV with the "I" jumper in place, so at double density it should be spinning at 300RPM. ImageDisk claims that reading and writing at 300kbps is successful. I have been using ImageDisk to translate the BIN files I've downloaded into IMD files with the following commands: D:\> BIN2IMD DISK1.BIN TMP.IMD /2 /U N=80 DM=4 SS=512 SM=1-9 D:\> IMDU TMP.IMD DISK1.IMD IL=3 (The two-step translation is necessary because BIN2IMD cannot directly write 3:1 interleaved data unless it's interleaved in the BIN image, so you have to use IMDU to reshuffle things... it's complicated!) Anyway, after doing this, what I end up with is a disk that is _almost_ usable. I can boot off of it, but it fails shortly after loading the UNIX kernel. I can run the 3B2's "dgmon" floppy diagnostics on it, and they almost pass, but fail to reliably read and write during the R/W test. Now, here's the thing: If I use the exact same media and low level format it _on the 3B2 itself_, the disks are 100% readable on the 3B2 and pass all floppy diagnostics with flying colors. So I'm trying to pin down what about my setup is not right. My pet theory right now is that the R/W gap and Format gap are wrong. The default values for the gaps when calculated by ImageDisk are 24/64. I've played with 22/32, 34/62, and 42/80, all based on reading the datasheet and/or old Linux "fdprm" settings, but nothing seems to make the disks 100% reliable on the 3B2 when written on the PC. Does anyone have any insight into the gap lengths used by the 3B2? Or, have you successfully written 3B2 floppies from disk image before? -Seth -- Seth Morabito

Now that tumble is running in my new workflow, I'll see what I can do.

Original HP 2116A is running again!

by COURYHOUSE＠aol.com

That is really neat to have an "A" We have a few manuals in the library and a few paper tapes. BUT! we recently were shipped crates of paper, some of which I never saw before in my life. There are some HP manuals in there Similar to what Al is mentioning. I will have to look again to see if we have anything out of the ordinary aside from the basic manual set. We have a 2116"B" here which was the Phx Union HS HP-2000 2000A main processor than became the I/O processor for their HP-2000F when Computer Exchange Inc. bought it. Unfortunately when I retired in the early 90's I did not save all the paper tape. I have the stuff in the drawer in the 2000 ACCESS cabinet ( yea was a neat addition to add a pull out drawer in the cabinet to keep taps, pens and etc in!) A few white boxes showed up in the garage at home I noticed recently when cleaning... always grateful to find neat stuff that got misplaced over 20 years ago.... We will wait to see what Al comes up with and see if a fill is needed from our sloooowwwwwwwww scanner..... Ed
