General question for PDP-8 fans: I've seen references to someone having created an RF08/RS08 replacement. Does anyone on the list know details of such a project?

COBOL quote in the news

When anyone with a tech company says "We can't find anyone to do X" what they really mean is "We can't find any new graduates to do X" because heaven forbid they should hire an older (like over 35) worker. There are plenty of older tech experienced folks working at hardware stores, who would jump at an entry level tech salary, but for some reason, human resource drones in tech companies are universally convinced that they would be too expensive or otherwise a poor choice. Sigh. <happy I have a good job finally> It's the same story as a few months back when B. Gates went before congress and asked for more H1Bs claiming he couldn't find any programmers. Jeff Walther

segmented memory models

by segin2005＠gmail.com

Note: This was written at a eariler date than mailed. This is due to the fact I personally do not have a net connection and read email whenever and however I find a unsecure IEEE 802.11g "Wi-fi" access point. As of such, I ask that would someone please be so kind as to compile all relevant replies to this email into a digest and email that to me, as at the last time I checked my email, I had over thirty thousand unread email messages (30,069 to be exact) from over the last 20 months or more and I am simply too lazy to junk them all -- it's a GMail account and the ratio of incoming daily mail to storage growth is low enough that accumulating email appears to be a non-issue, even with 3 very high volume mailing lists subscribed; wine-dev, cctalk, and I think LKML. (Normally, I sort this all out using a rather ad-hoc set of regexp filters in Thunderbird) My question is rather perplexing. When most people refer to segmented memory, AFAIK, they mean banked memory systems, where each segment is like a piece of paper, that is, seperate from each other. On the contrary, the Intel 8086's segmented memory model is like lessing some source code and using the terminal arrow keys or K/L to move the display one line; given segment X, segment X+1 contains almost all of the memory of segment x, except for a new line of 16 bytes (which the metaphor between a new line in 'less' and the segment differential is rather ironic; most hex editors I have seen display exactly 16 bytes of data per line) The question is, is the Intel 8086's memory model brain-damaged? IMHO, extremely much so.

question aaout ISP's

> I'm based in Philadelphia. My current provided is disabling > telnet capability at the beginning of September. I would like > to know if anyone knows of a service that will permit me that > capability? > bs Don't use standard ports. My provider (Comcast) blocks port 25 (mail) inbound and outbound, and doesn't allow relaying through its mail servers. Instead I use port 2525 and an external mail relay service. With telnet, you won't need a relay service if anyone accessing your system knows that it's on a non-standard port. Do you really need telnet though? SSH preferable if your host can run it.

AT&T 3B1 Unix PC

by mikelee＠tdh.com

Anyone collect and/or need parts to the AT&T Unix PC? I've got a pile of systems I dismantled over a decade ago, and don't really want or know how to put back together. I bought them "new" as surplus by the pallet at the time, and about half of them were defective with only displaying horizontal lines when turned on. The monitors are perfect, I also have the 20Mb MFM drives and 5.25" drives, as well as the mainboards, plastics etc. I'm not sure exactly how many and what I have yet, but checking for interest here. Please reply if these are of interest at all. Any suggestions on the line problem? Mike Lee

my mac SE problems

by jlobocki＠gmail.com

ok, so i got a mac SE off ebay, for a decent deal. now a logic board, floppy drive, CRT tube (I let the magic gas out of the first one) later, im back where i started. i write a boot disk with my powerbook 1400cs, pop it in. it boots up to the system software. i go to hd sc setup like i did when i used my external floppy to boot, and it shows nothing. the first time, i got to boot with an external floppy and the old logic board, and it showed the drive until i attempted to format it, which it wouldnt. after that, i couldnt see the drive again, and my boot disk kept getting wiped each use, and id have to reload it. so then, i replaced the board, the CRT, and the floppy, and now its still doing the same damn thing as it was before. is it possible i need new or replacement SCSI and floppy cables? its just being really weird.....

AIX 3.2 Weird Networking Problem

by devonstopps＠gmail.com

Thanks to all who helped out, I've got the problem sorted out. AIX 3.2 does not have a rmtcpip command, but, doing an rmdev on en0, then issuing the mktcpip command has solved the problem - guess it was something left over from the last site. T.H.x. Devon

Double-Sided disk drives reading Single-Sided disks (HP 9122 vs 9121)

by jplist2007＠kiwigeek.com

Hey guys; This may, or may not, be a silly question, but in all my years of fiddling, I realised I had never tried this, so I'm unsure of what the results will be. My HP Logic Analyser (1630G) can talk to a HP 9121 via HP-IB. I have found a 9122, which is a double-sided version of the same device, as far as I can tell. I'm fairly confident the 1630G won't care - but the diskettes that I have (inverse assembler pack, thanks Gavin - you rock) are single-sided. Is there any reason that the 9122 DS drive won't read a SS diskette for the 9121? Thank you for your help! - JP

BASIC-Plus decompiler

by tony.eros＠machm.org

> What I'm remembering is a BASIC decompiler, written in BASIC, > that was running on RSTS/e circa 1983. So that was BP, not BP2, > right? Circa 1983? Chances are it's BP2. When I was a high school senior in 1978, I wrote a BP2 decompiler for an Independent Study project, so BASIC-PLUS-2 had been around for quite some time by 1983. I got some of my first exposure to computers through Project DELTA (hi, Rich!!), and was fascinated by PPCODE. I still have a source listing at home on a VERY faded length of Teletype paper. -- Tony

IBM Model M keyboard spares

The Model M came out *waay* after the PC. The 84-key is the one for the PC. I don't think the Model M is even compatible with the PC. Peace... Sridhar ------------Reply: People reverently talk about the Model M as though there was only one; in fact there were probably almost 50 different versions, including at least one for the late model XT (no indicator lights) and I *think* that at least one version was dual-mode as well. See: http://en.wikipedia.org/wiki/Model_M_Keyboard To the OP: I have a few different ones in the scrap pile somewhere, if you can send me a picture of yours; does it have the removable keycaps? I understand that replacing the spacebar on one of the older Model Ms is a bit of a challenge BTW. m
