Thanks! Just checked the DELQA printset which gives the following for the 20-pin BERG: 1 Power 2 (key, pin blocked) 4 Power Return 6 Receive + 7 Receive - 10 Transmit + 11 Transmit - 12 Shield 14 Collision + 15 Collision - 18 Control out circuit A 19 Control out circuit B 20 Fuse OK which seems to agree entirely with the DEUNA information you have.

That would be great! I don't think there is any particular urgency, now that I have the BERG pinouts, but I'm sure the community at large (and me) would appreciate having that online somewhere in the future. Many thanks! - Jared

Yes, I've got a few AUI-to-TP transcievers and I plan to use one of them to make the connection to the LAN. Do you know what the extra two lines are for on the DELQA?. Do they also exist on the DEUNA? Better yet, can you point me to the printset for a DEUNA? > You can also use the DELQA / DEQNA cab-kits interchangeably, > for basic ethernet operations on the PDP-11. . . Yes, thanks for confirming this. I do have a handful of DEQNA setups and last year picked up a DELQA. Indeed, I successfully used a DEQNA cab-kit on the DELQA when I tested it out. Thanks for the good info! - Jared

Nuclear Data ND-812 info...

by derschjo＠msu.edu

Hey all -- Got my hands on a pair of Nuclear Data ND-812's (thanks, Mike!) and I'm looking for any info/software for them. I've got the stuff off of Bitsavers already :). 12-bit machine from ~1971, toggle switches and blinky lights. Actually, these are BR2412s -- evidently military versions of the ND-812. They're green :). The other major differences (from glancing through the maintainance docs on Bitsavers and comparing to mine) are that the ND-812 used core memory, and the machines I have use DRAM (Looks like 24kw of Intel 1103's!). And as a result the BR2412 has a completely different power supply, which I'd love to have information for so I can test it out before powering these things on. And I assume the color scheme was different :). Anyone know the history of this machine (or even the company itself? Did they make any other computers?) I can't find too much information on the 'net... Josh

Using WatCom WASM.EXE - How to obtain a listing file?

by jhfinedp3k＠compsys.to

This must be a really dumb question, but I don't seem to be able to figure out how to obtain a listing file. I just downloaded open-watcom-c-win32-1.7a.exe and installed it without any difficulty. It assembles my source file and I can link with wlink. It all works perfectly. After more than 2 years, I am able to duplicate the DLL file that I am using and which I want to modify. But wasm /h command does not even mention anything about a listing file! Is there any way that I can obtain a listing file of the assembled source code? Thus far, WatCom has the only assembler / linker pair that I have found which can duplicate the DLL that I am using. So shifting to a different assembler may not be useful. Does WatCom have another EXE file that I am missing that is used to produce a listing of the assembled source code? Also, it would be helpful to have a link map, although right now I probably would not know what to do with one. Sincerely yours, Jerome Fine

Computer Automation library floppy images

by hamren＠sdu.se

> There are now about 400 disks from Computer Automation's program > library up at http://bitsavers.org/bits/ComputerAutomation/8_imd. > They are in imagedisk format, and are all single sided, single density. Excellent. Thank yoy, Al! I will download and extract them where I can. I have written a program that can decode LSI-[24] file systems and file storage format. I'll inform the list when it's done. Al: You post was also addressed directly to me, but I did not receive it. As far as I can see it never reached my mail server. /Lars Hamr?n

OT - Simple Read / Write Detection on Individual SATA II Drives

by jhfinedp3k＠compsys.to

I realize that they don't qualify for the 10 year rule, however, since I will be using them to run Ersatz-11 to run RT-11 software from 1985 which does qualify, I hope that this question is not too OT. Up until 10 year ago, even drives for a PC had individual LED circuits which provided a status when a read or a write request was being processed. Now, I can't find any drives which have such an LED. Tony (any anyone else who may know the details), perhaps you have the hardware knowledge as to what might be required to add a circuit with an LED (or anything else that would do the job) which would provide a status when a SATA II drive is being accessed. Separate read and write would obviously be even better, but a single LED would be more than adequate. My concept would be to modify the existing cable between the motherboard (or the controller) and the drive so that an LED could be wired in with the appropriate hardware. The wires on the LEDs should be long enough to allow them to place the LEDs outside of the case so that the user can watch then as needed. Even better might be really long wires that would allow the LEDs to be attached to the monitor. From what I know of LEDs, the current that they draw would not be a problem with wires that are many feet long. Can anyone suggest if this is a feasible project? I realize that the motherboard which has a display LED status capability for all hard drives is available, but then I don't see the status for an individual drive (I have 3 SATA II drives), let alone if the request is a read or write - assuming that it is possible to show read and write separately. Plus if the LEDs were attached to the monitor, that would be much more convenient. I actually have such a software display on my monitor right now for each of my UDMA 100 drives which is really helpful, but I don't know of any software which is set up to do that with current systems Sincerely yours, Jerome Fine
