They're called "false cognates." My favorite one in Spanish is "embarazada,"
which would make you very embarrassed if you use it to mean "embarrassed"
(as it means "pregnant.")
There's the story of a female exchange student who told her host family
"Tengo hombre" ("I have a man") when she meant to say "Tengo hambre" ("I'm
hungry"). When informed of her error, she blushed and said "Estoy
embarasada!", which only compounded her chagrin. (She said "I'm pregnant"
instead of "I'm embarrassed.") :-)

OK, I've been watching the thread for a couple of days about battery
damage. I just realized what's confusing me. I'm also fully aware that
I'm about to expose the true depth of my electronic ignorance.
"Never recharge a lithium battery?" (Yes, I've also been watching the
grammar thread.)
My laptop has lithium-ion batteries. That Apple camera came with
"Energizer Hi-Energy Lithium" AA cells that I was planning to stick in
the wall-wart battery charger. I'm fairly certain they're _meant_ to be
rechargeable.
I think I'm missing a crucial concept here. As they say in West
Texas, "Could somebody please 'splain this wonderment to me?"

I heard the advantage to Lithium batteries over Alkaline is that Lithium
provides steady voltage right up until it is dead, where an Alkaline
looses voltage as it dies.
Any truth to that? Or is it simply Lithium provides more amperage at a
given voltage?

Rick,
You are correct!
This command set remains one of my all time favorites. I just wonder who was the engineer who developed that command. We had a drum storage device on our 2000 and it spun a bearing one day and made a very loud squealing sound that scared the bejesus out of us. Before it died, I did have the opportunity to sanctify and desicrate several files. If you have any other 2000 tidbits like this one, please post them.
Thanks!

I recharge primary alkalines all the time; roughly doubles their life, although
useful time before they need recharging drops substantially. Can't let them

Incidentally, another statement often made which is also incorrect is
'Do not recharge alkaline batteries'. It's intended to apply to the
primary alkaline batteries like Duracells. But, of course, the NiCd (and
other) batteries use an alkaline electrolyte and those are designed to be
recharged.

I certainly don't mean to question your word, but can you provide specific
references?
Material published by William S. Burroughs (references available upon
request) indicate that the problem was that *exactly* the proper amount of
pressure had to be applied to the actuator lever in order to produce a
correct result, which was nearly impossible. The hydraulic piston ensured
that the same force was delivered to the machine no matter how much
pressure was applied (as long as it was enough to depress the lever). This
gave the Burroughs machine a huge advantage over competing products
(several of which existed at the time and all had the same problem), and
allowed it to capture the market.

I just did that and came up with this site

which contradicts Mr. Lawson's "destructive jam" theory (no offense to John

QNX is a perfect solution for this since it's real-time and has great

Or, maybe you'd prefer to cook up an OS from scratch.

The smaller switch, S1, controls the vector. S1-1 to S1-8 correspond to
bits 9 to 2 of the vector, respectively. ON sets a '1' in the
corresponding bit position. Default is OFF, OFF, OFF, ON, OFF, ON, OFF, ON
= 00010101 which gives a vector of 000124.
The larger switch, S2, controls the base address. The DRV11-B has 5
registers, with factory-standard addresses as follows:
WCR Word Count Register 772410
BAR Bus Address Register 772412
CSR Control and Status Register 772414
IDBR Input Data Buffer Register 772416
ODBR Output Data Buffer Register 772420
Note that the CSR is not the first address.
S2-1 to S2-10 correspond to bits 12 to 3 in the base address. ON sets a
'1' in the corresponding bit position. Bits 15-13 are fixed at '1'.
Default is ON, OFF, ON, OFF, ON, OFF, OFF, OFF, OFF, ON = 1010100001,
which gives 172410 (corresponds to 772410 with 18-bit addressing).

It might work. It might not. The DEC diagnostics make use of specific
facilities in the RLV (QBus) controllers that aren't in the RL (Unibus)
controllers, and may or may not be in a 3rd party device. The early
diagnostics only cover RL01s and RL11/RLV11:
ZRLA?? Controller Test Part 1
ZRLB?? Controller Test Part 2
ZRLC?? Drive Test Part 1
ZRLD?? Drive Test Part 2
ZRLE?? Performance Exerciser
ZRLF?? Compatibility Test
where ?? means any revision (a single letter) and any patch level (single
digit), as usual for XXDP.
The Performance Exerciser would probably work *once the disk is formatted*,
as it just does a lot of read/write/seek tests. The compatibility test is
pointless for a DQ614 as it tests moving packs between drives.
The later diagnostics are for RLO1s or RL02s and RL11/RLV11/RLV12. There's
an extra program to allow you to read and write the Bad Sector Table which
exists on a real RL02:
ZRLG?? Controller Test Part 1
ZRLH?? Controller Test Part 2
ZRLI?? Drive Test Part 1
ZRLJ?? Drive Test Part 2
ZRLK?? Performance Exerciser
ZRLL?? Compatibility Test
ZRLM?? Bad Sector Utility
Finally, there's a pair of diskless tests written specifically to cope with
differences between Unibus and QBus controllers:
VRLA?? Diskless Test 1
VRLB?? Diskless Test 2

I gave the filename to both Jay West and Hans B Pufal

achh died because of the huge number of posts from people who had bought a
motherboard, case, and video card and wanted help to make it work. We
referred to them as those who belonged on "alt.fix.my.peecee" or similar.
There were some amazing arguments between newcomers, who thought such
lamers should get a polite answer including a solution, and veterans who
argued that doing so reduced the S/N ratio and encouraged even more OT
crap, and that people should read the guidelines. Doubtless some members
of classiccmp will remember Leon Heller. And, yes, that is exactly why the
'bot was employed (it had been tried on achh, but since that wasn't
moderated, it had to be a retro-active cancelbot, rather than an
approvalbot).
As for active, well, yes, I saw the post. And all the others; there must

Luckily the HD is OK. The floppy drive occasionally throws up seek errors
and I haven't been able to clean all of the crud off the head stepper motor.
I've found a source of replacement drives in the UK and at very reasonable
prices.
Cleaned up the mother board with warm water, detergent and a stiff brush,
then let it bake in the oven at 70C for an hour. Had to use a small grinder
and a wire brush on some of the metal work. Installed DOS and I now have
a happy computer :-)

OK. From what you've written there, and a few other places, I assume you

That makes sense. On an M9312, it simulates a power-down and then

Are they M8728-AA or M8728-CA? The latter is only 16KW. The easy way to
tell the difference, if there's no -A or -C beside the number, is that on
etch revision B and higher, the 64KW board is fully populated with 64K
DRAM, while the 16KW is only partly populated. I suspect there might once
have been a fully-populated 16KW version that used 4K DRAMs, though.
I was, no surprise to anyone, wrong about their having switches -- showing
my ignorance about the specifics of 11/70's. Most of the things I've
written are gleaned from the meagre information in one or two of the
processor handbooks, or from my (incomplete) collection of microfiche.
Anyway, the memory box has switches on the front (and I assume you've
checked those?) but as far as I can see from the 'fiche, the memory card
base addresses depend only on their position in the box. So the two cards
have to be adjacent, and nearest the other cards, I think. Do you agree?
It looks as though the box might be set to the wrong address -- 400000 is
131072 decimal, or 128K -- and is only showing 16KW (32KB) of memory. I
don't know how you set the address of the box, though.

> It is the 23-233F1 diag rom.
OK, I've found some data (actually the listing) for that ROM. It's
assembled at 165000 (but it looks like position-independant code, so that's
possibly not its real address). It ends at 165776, ie 1000 bytes (octal)
later. It is indeed an 11/70 diagnostic ROM for the M9312, probably just a
later version than the 23-616F1 my other docs refer to.
The docs say there's no way to enter the diagnostics directly, only by
entering a bootstrap at the "run with diagnostics" address. They suggest
that would be 173006/173206/173406/173606 depending on whether you're
booting from a bootstrap ROM in socket 1, 2, 3 or 4.
The docs also say that when the 11/70 powers up (or you press a boot switch
attached to TP1 and TP2 on the M9312), it loads the PC from address 773024,
and PSW from 773026. And indeed every boot ROM has a reserved word at that
address for the PC, followed by 000340, which is the usual interrupt mask
to set in the PSW for booting. Every ROM has code (opcode SEC) starting at
173x04 leading to a BCC BDIAG at 173020. In every boot ROM, that branch
goes to an absolute jump, JMP @#DIAG, which in turn leads to a PC-relative
jump at absolute address 165564, which goes to 165000 (the actual code is
165564 000167 177210 DIAG: JMP START).
Why do you think address 777644 is the diagnostics ROM start address?
All the 11/70 tests halt on error (unlike the CPU diagnostics for the 11/34
and other processors, which loop on error). The first section tests
assorted instructions that needn't to use memory, the secondary CPU tests
use the stack (R6 set to 000776). However, the very first instructions in
the diagnostics code store registers at 000700...000704, and use 000706 to
hold a flag which tells the code whether it's running on an 11/60 or an
11/70. If the memory isn't working, this will cause problems later in the
diagnostics.
Address 165344 is one of the error halts partway through the secondary CPU
tests (assuming the diag ROM starts at 165000). What it does is set
SP=776, then does a PC-relative JSR to the address 2 ahead of where it is.
The code there checks to see if the top of the stack contains the correct
return address, and should halt at 165326 if it doesn't (it should halt at
165320 if the JSR didn't execute). If it does see the correect return
address, it adjusts the stack contents, does an RTS, ending up at 165342.
At 165342, it pushes a zero and an address on the stack and then tests
RTI. 165344 is the address of the push instruction, and 165350 is the RTI.
That's folowed by a jump to the next test, which is the memory-sizing
routine.
So having it loop until you stop it, and then halt at some address ending
in 344 doesn't make much sense to me. Either you're not starting at a
sensible address, or there's something wrong that is sending it into a
loop. That could be a CPU fault, or maybe (I've not read all the cache
test code) something to do with not having memory between 000700 and
001000.

You probably remember that the rapidly-increasing number of off-topic posts
led to a variety of attempted solutions. That culminated in the creation
of a moderated group, comp.arch.hobbyist. The moderation is done by a
'bot, with human backup, but the group traffic level is very low. I
suspect that's because the 'bot is too good, and it's actually hard to post
as a newcomer, so interest has dropped off. The last few times I tried to
post, my posts bounced, and attempts to contact the human moderators
failed. Maybe I was just unlucky. Anyway, you'll find the FAQ and charter

it's seriously out of date and a lot of the links are broken.

The actual idea was to create or assist with the creation of a completely
"free" (GNU?) implementation of VMS that "looks and feels" just like the
original.
The next step was to port this version of FreeVMS to i386, VAX, and AXP.
I've seen a few projects that have started or have stopped that attempt to
achieve similar goals.

Hello. About the probes with the DILOG DQ614 over one PDP-11/23 PLUS
with one MFM hard disk using the diagnostics program for these board,
I have some matters to speak about:
* Somebody spoke about a possible modification of the U55 chip.
I have the reference of the chip mounted. It's the 55U-91358.
In fact, the order number of some chips of the board is:
25U-91353
69U-91354A
64U-91355
21U-91356
22U-91357
55U-91358
The question is: Could be used some XXDP diagnostic to determine
the possible problem of the board that I told in my previous message
about it ?
* I want to use another hard disk, one IBM MFM full height of 44 Mb.
Is one Type 31 (for the IBM PC) disk. Somebody has the complete
geometry of it ? I don't have it actually available in the BIOS of my PCs,
but I suppose that one 486 or 386 could have it.
Thanks and Greetings

Hmm.. Lots of DEC CPU backplanes have dedicated slots for various things,
and the position/order of the boards is very important. I don't know if
the 11/70 is like that, but I'd not be at all surprised if it were. Have
you checked that everything is in exactly the right place? If you've
removed any optional boards, have you checked in case any jumpers need
replaced?

Do you mean that someone swapped the wires from their normal places, or
that someone added a switch that wouldn't normally be there?

That's an unusual address, and it's only 32K bytes (16KW). You said you
had two 64KW boards. What type are they? They probably have switches to
set their base addresses. Are these set correctly? It would be worth
trying just one, set to address zero, and see if that improves things.
Start with the minimum in the system, and build it up as you get things
working.

It's an odd sort of address. I'd expect it to stop at an address in the
ROM. If you had to halt it manually, it must have been running in a loop.
Why that address, I have no idea, because according to the M9312 manual,
it only runs code from ROM until it has booted some device. According to
the M9312 manual, it runs various CPU instruction tests, then tests memory
>from 1000 to as high as it can go (up to 28KW), then tests the cache. It
will halt if it gets an error in any of the memory or cache tests, but you
can press CONTINUE to ignore the fault and carry on.

All DEC ROM numbers begin 23-<something>. All DEC diagnostic PROM numbers
end in F1. The correct bootstrap for a M9312 in an 11/70 is 23-616F1. If
that's not what you've got, it's unlikely to work correctly.

Well, you ought to set it to the correct value, obviously, but I've no idea
what would happen if you set it too high or too low. Yes, it's the high
limit.

I think the bus init is supposed to set them to zeros. Of course, the map
may be faulty. Normally each memory board has a switch pack to set its
starting address. What type of board(s) do you have?

i think you and i are saying the same thing.
except i am putting more emphasis on the bot being self controlled
with outside help. you are putting more emphasis on remote control
with eventual self-control.
the thing is; the brain is the easiest part. the brain of the bot will
be self learning so each bot will learn as it goes as opposed to me
having to do a lot of designing.
Follow nature for ideas
for example a little child has just enough knowledge to ask about what
he or she doesnt know about.
so each bot will know just enough to refer to the master os on whatever it
doesnt
know until it learns.
it will be set up to sort , retain, recall various information.

Yes, U is the ground for V...Z (K is the ground for L...P). X-U (with all
other bank pins disconnected) gives a start address of 00100000 (32K,
decimal).

If you have any devices in the lower 2KW of the I/O page, you should
disable memory access to that area. If you don't, you'll get a conflict
when both the I/O device and the memory try to respond to the same address.
However, not many small QBus systems have I/O devices in that address
range (160000-167777). It's normal to leave the whole I/O page for I/O
devices, and disable memory in that area, though.

I don't know; try it and see :-) I suspect if you set it to 18-bit mode
and use it in a 22-bit system, it will respond to multiple addresses. If
you set it to 22-bit mode and use it in an 18-bit system with no
termination on the upper 4 lines, it may respond to noise on those lines
and not turn on when it should. The bus signals are active low, so if
there's no signal they should float high and read as zeros -- but life and
bus systems are not always so predictable.
OTOH, if you have a 22-bit processor, it's easy to upgrade the backplane by
soldering four pieces of wire-wrap wire to bus the extra 4 address bits
(and upgrade the BDV11 if necessaary).

Faulkner was an amateur. Try picking up "The Ticket That Exploded," "The

Congratulations for your advance. I have one PDP/11-23 PLUS
with 128 Kwords of memory. I don't tried to boot it because
I need to take my own RL02 from Germany where it's actually.
But I use to startup this V6 distribution under Bob Supnik's
SIMH v2.8-5. I've detected the panic problem in multiuser mode
some months ago in my private hackings. I should agree to know
all your advances and hacks in this aspect, please.

Well, I've only been on this list since October, but I think I've gotten a
pretty good feel for the style and flavour in that short time, and all in all
it's a great resource, informative (although, like you, I spend a lot of time
scrolling through the DEC stuff :), and often a lot of fun to read.
Actually Sellam is one of my favourite posters; his comments are usually
quite appropriate and I really appreciate his often acerbic, no BS style; he
apparently values his time (and mine, as the reader), whereas a number
of people on this list apparently have a great deal more time available
than I do (and that's not a criticism; in fact I envy them).
No problem with the 'A' word either, especially when used self-deprecatingly
or as a warning to me that if I say something foolish I might not be treated
with gentle understanding and kindness; I am surprised though, that people as
intelligent as everyone on this list seems to be would not find a more
sophisticated way to show their contempt for someone else's opinions than
to just call them names (and seriously mean it as far as I can tell).
Just my C$.02 worth; as a newbie here I've got no business judging anybody.
But as a newbie, I do want to add something FWIW:
The original replies to Joee made the point that his way of expressing himself
might backfire, in that someone who might have something useful (to Joee) to
contribute might either just skip over his posts or judge that he wasn't 'worthy'
of their help. Then the replies to those replies suggested that if we alienate
Joee we might lose out on something _he_ might have to contribute.
Well, speaking for myself, although I too was mildly annoyed by Joee's style
and _apparent_ attitude, I wasted more time on and was more annoyed by
the subsequent squabbling, although the _serious_ discussions of language
were interesting for the most part. Joee himself must be rolling on the floor
laughing over what he stirred up; reminds me of the story of the person who
was incorrectly diagnosed as retarded for 2 years ("And they called ME retarded!")
I do love the irony that while there's lengthy discussion over whether it's
appropriate to type without caps, there's little interest in whether it's
appropriate to call someone an asshole - style over content, sign of the times...
My point (at last!) is this:
When I first started looking around for a place to find takers for the 30 year
accumulation of hardware, software and documentation I am getting rid of,
this list stood out among the many others as an intelligent and fairly (but
not too) serious and intelligent place; if I'd run across it a few days ago, I would
have passed it by as just another list where people spend more time yakking
and flaming each other than discussing computers and helping each other,
because the people who have relevant things to contribute either remain quiet and
invisible, or their posts are buried among the other stuff.
Maybe, just maybe, there are other people who could make substantial
contributions to this list and vintage computer collecting in general who'd feel
the same way, despair of finding a suitable place to post, and move on or just
toss out their stuff and whatever resources or expertise they may have.
I like your idea of separate lists, in fact I am on a list that does just that;
one list for the actual purpose of the list, and another for OT threads, rambling,
ranting and raving. Works very well for me; I have a choice whether to just
quickly read the important stuff in case there's something urgent to reply
to, or grab a cuppa and 'socialize' for a while.
Oops, this rant's getting longer than even Richard's recent ones; just wanted
to say that while we're certainly going to yak among old friends and ramble OT
occasionally, maybe we should try to stand out among all the other lists and stop
short of the point where someone new with something to contribute will pass
us by and write us off as just another bunch of assholes...

Re the HD: when mine failed a few years back, I heard
lots of info that it was an ST-512 drive with a special
connector. Apparently not; installed a standard 80Mb
(MB? mb? mB? :) IDE drive, Disk Manager to get around
the fixed drive type, and Bob's your uncle.
Good luck with the cleanup.
