I dug up a HP 7580A and hooked it up, it seems to work fine. But the question is now, how do I make it do anything, WITHOUT a system ? Pressin pen down doesn't do much, and although I can move left and right I cant make it move the paper forward and backward. Anyone ?

Emulex DM01 information

by gordon＠gjcp.net

Hi there, I need to find out about the ST506 cables for an Emulex DM01 QBUS card. I've just got one with no cables. I understand that it's similar to other Emulex MSCP cards (makes sense really) but it has a 50-pin cable to connect the drives up. Anyone know how to make up a cable for this? Or even, got a spare cable? Gordon.

VCF Midwest update?

When it first started it was one of the most interesting shows I've ever been to. They had a really nice mix of large vendors and small companies. Some even just had exhibits without any specific sales ( they did advertise ). Over the years, it did evolve and then died. First I think it was that the fellow that originally ran it sold it out. This meant that it was intended to be a solid profit operation. No more loss leaders ( ask a successful retailer what a loss leader is ). Another thing happened at about the same time. Strong union forces in San Francisco force the shows to only use union riggers to move material from docks to displays. There was no way the little interesting exhibits could afford this. What the owners of the show didn't realize then was that they should have subsidized the smaller exhibits. It quickly because another trade show that one couldn't get their company to pay one to go to. No one would want to go there just for hobby sake any more. Let the Vintage Computer Fair evolve but remember that it is intended to be a hobby related show. It should be enjoyable for all that go there. From my past experience, there are several changes I'd make. First, I'd restrict the size of exhibits to not much more than equipment size. I'm not much into museum exhibits for these kinds of shows. If people are interested in something, they should stop and talk to the exhibitor. The display should not distract from the machines and information ( despite trends I've seen at the recent festivals ). If I was expecting such empty presentations, I'd go to the Tech Museum in San Jose or the Intel Museum ( I've only been to each once and see no reason to return ). Exhibitors should have a place to sit that is not in the aisles that the public use. There should be a place for the public to stop, sit and chat with the exhibitors. This was really clumsy at the last VCF. I realize that it is a space issue. I also realize that some like the "crowd pleaser exhibits" that use several tables to display a few items. I have no problem with large exhibits like the analytical engine or the Dec machine. I just feel that space should be used more to create interaction between exhibitors and visitors and not so much to create the one pass Tech Museum type exhibits. As for collecting from exhibitors, I have no issue other than making it clearer to the exhibitors that they'll have to pay such fees. The first time it was a surprise to me as well. The fee amount wasn't an issue. Just my thoughts Dwight

Interex closing down.

by MGemeny＠pgcps.org

I was just looking at Interex and found some stuff left at the following: ftp://ftp.interex.org <ftp://ftp.interex.org/> I am not sure what it is, but it looks like RTE stuff. I just thought someone might want to archive it. Mike Gemeny

computing nostalgia

by jwest＠classiccmp.org

Just got back from another out of town jaunt, and am trying to catch up on email. This one was sent to another list I am on, and I thought people here would appreciate it. See below. Jay --- >From http://www.ypsidixit.com/blog/archives/2005/08/remember_punch.html August 01, 2005 "Remember 80-column punch cards? "Just think of the concept--the data is made up out of thin air! The card is just there to organize the holes" How many cards would it take to encode a 3-minute mp3? Answer: "Assuming a non-Hollerith encoding with eight bits per column, and an MP3 file encoded at 128kbps CBR, there would be 36,864 cards in that deck, and the card reader would need a throughput of 205 cards per second. It might be wise to include an 8-column sequence number, however, so that a misordered deck can be repaired by a card sorter; with 72 data columns per card, the total is precisely 40,960 cards (40K cards), requiring a 228 card/second throughput." The 21 boxes of cards needed would by 5 feet 9 inches tall. That such a huge leap in technology is well within living memory is astonishing.

PC<>PC File transfer (was classiccmp knowledgebase)

Hey, that's why I think it would be a useful and interesting FAQ. I thought the other guy's CTRL/Z preservation method was quite cute, too. I'm intrigued by solutions that would require a minimum of prep or magic tools on the sending PC. - John ----------------Reply: Assuming the server is also running DOS, it seems to me the least prep or magic would be to use Interlnk/Intersvr, included in MS-DOS since around version 5. It can use serial or parallel ports, redirect remote drives and printers, and can do a remote install if the receiving computer doesn't have a copy of Interlnk. Needs a null modem serial cable of course, or a LapLink type of Parallel cable or adapter. Same as LapLink; not as fancy, but free. Check out the help files for Interlnk & Intersvr. Didn't we just have a lengthy discussion about this a while ago? mike
