Network cards and Win98SE

by charlesmorris800＠centurytel.net

I have tried for two days to get wireless networking running on my old PC under Win 98SE, so I can use PUTR without a separate partition or boot. XP is on an 8.4 GB drive. 98SE is on an older 540 MB drive. There are two network cards (a Netgear WPN311 with Atheros chipset, and an Encore ENWLI-G2 with Realtek 8185 chip) and neither will work with Win98SE. I have tried the manufacturer's drivers, Atheros drivers, Realtek drivers... none of it works. The Realtek driver installs but gives a fault in RUNDLL32. Netgear's website claims that the WPN311 can run under 98SE and later. Some sources for that driver package say it starts with XP. Although I would tend to believe the manufacturer... The same Netgear card in the same motherboard was working correctly with the XP drive. I even did a fresh install of 98SE. Then installed the WPN311 software, then the card. Windows says the card is installed and working properly. But the Netgear utility won't run (hangs, Task Manager showing wlancfg5 not responding). That's usually because it can't see the card. Searching the net including various forums from years ago hasn't helped. So I'm about to give up. Wasted enough hours on this. Back to XP with a DOS partition for running PUTR. Unless someone has a better idea :) thanks Charles

Possible PUTR bug?

by charlesmorris800＠centurytel.net

Just an update... I spent an entire long afternoon wrestling with that old PC, trying to find some combination of HDD jumpers and BIOS settings that would allow the XP hard drive to boot with another drive attached (either on the slave connector or the secondary channel with the CD-ROM removed). No dice. So I had the bright idea to use Minitool's Partition Wizard, and shrink my Windows partition so there'd be room for a newDOS partition. But it won't even run (probably because I have only 64 MB RAM on that box). Grrr. It's unbelievably slow anyhow, so more SDRAM on order, which is really cheap these days. I'd get a newer PC for the workbench, but need to keep the old motherboard because there are a couple of devices (including a PB-10 PROM programmer) which are ISA slots. So, this has become a Windows/PC (ugh) project instead of just being able to play with my PDP-11...

What is this?

http://www.myimagecollection.com/webpics/unknownmachine.jpg The model number looks like 9603. Can't tell for sure. The box in back has the 14xx flavor.

Extra copy of "LSI-11, PDP-11/03 User's Manual"

by jnc＠mercury.lcs.mit.edu

As a result of an inventory error on my part, I wound up with an extra copy of "LSI-11, PDP-11/03 User's Manual" (EK-LSI11-TM-003). I'd like to pass it along to someone, provided I'm reimbursed _most_ of my eBait expenditure on it (it was not, alas, cheap). Anyone interested? Noel

PDP-11/40 available, Arizona

by athornton＠gmail.com

I have been invited out to the site tomorrow morning to take an inventory of what?s there (I live near the machines). I imagine that I may well have a lot of photos that I bring to the list and say ?what is this?? The owner has assured me the machines will not be sent to the scrapper and that there are multiple interested parties, which is good, because I really don?t have a good place to put 8 cabinets of PDP-11. Not that having an 11/40 running Sixth Edition Unix wouldn?t be cool. I?ll report back once I have an inventory. Adam

HP 1000 A900 ("Magic") Questions

by pbirkel＠gmail.com

Aficionados; I'm interested in acquiring an HP1000 A900, in any form-factor. (http://www.hpmuseum.net/display_item.php?hw=594) Basic need would be a chassis/backplane/PS and minimal set of CPU/memory/HPIB-controller/terminal-IO PCA, however I'd be interested in simply acquiring a PCA-set and I'll work the chassis/backplane/PS separately. Even single PCAs would give me a helpful push forwards. And I need to stick to my hobby (beer") budget. I'm located in Maryland, USA, and pretty sure that the cost of overseas shipping would be ghastly for a chassis. But maybe not as bad for the tower configuration as for the rack-mount. If I understand correctly, the CPU consists of: 12201A A900 Sequencer Card 12202A A900 Data Path Card 12203A A900 Cache Controller 12204A A900 Memory Controller 12220A 768KB RAM (Or I presume 12103D 1MB, 12221A 3 MB, or 12221B 8 MB.) I imagine that I'll need to synthesize my own OTT "frontplane" for the memory. 12009A HP-IB Controller 12040D Asynchronous Multiplexer interface board Thank you for your insights, and opportunities (I hope), paul (offlist at pbirkel at gmail.com)

Possible PUTR bug?

by charlesmorris800＠centurytel.net

John Wilson confirmed that his program was designed to work with one floppy and an HDD. He says strange things happen if one tries to use two floppy drives instead... just as I found ;) I removed the second floppy drive, dug out an old 540 MB hard drive (with Win 95 on it) and hooked it up to the PC. Started Win95, then "Restart the computer in MS-DOS mode", copied PUTR to the C: drive and started it. PUTR now works perfectly, transferring files in both directions to an the emulated RX33 (3.5" floppy). The PDP-11 can read and write those disks on its generic 3.5" floppy "RX33", too. :) Now I just have to figure out the PC partitions/hard drives to make using PUTR as simple as possible.

Bug in PUTR?

by charlesmorris800＠centurytel.net

I'm having trouble copying files from my PDP-11 (RT-11 format) into an old Windows box using the last version of PUTR. It appears that WinXP does strange things with the hardware (3.5" 1.44 MB drives aren't actually RX33's although my RQDX3 controller believes they are). So I made an MS-DOS boot disk and run PUTR directly on MS-DOS (instead of the WinXP DOS window). Unfortunately MS-DOS 6.22 can't recognize my hard drive since it's NTFS-formatted, so it all has to be done in floppies. Both WinXP and MS-DOS know that A: and B: are two separate drives. Likewise the BIOS settings. I can copy files in DOS and Windows back and forth between the two drives. And I can MOUNT B: as a logical device DU0: (or without a logical device name, as B: /RX33 /RT11), and read its directory. But when I try to copy a file from A: to DU0:, the B: drive light flashes briefly, and then PUTR tries to write over the A: drive (blocked by the write- protect tab once I wised up)! So how on earth can the BIOS, MS-DOS and WinXP all know that A: and B: are two separate drives, but PUTR tries to write to A: even though the command is to write B: ?? I also tried switching the PUTR disk into B: and the RT-11 formatted disk to drive A:. Same problem (tries to write over the source disk which is now B: even though the output filespec is clearly A). I had a look at the code but nothing's leaping out at me. Although it's been many years since I wrote any 8086 code...
