I'm confused. I thought they were the same.
What do you mean by Beehive? If this is related to the Beehive section of
the Walnut Creek CDRom, then I see the file \beehive\text\member.txt has an
Australian address in it.
"Australian" Microbees are quite common here (because I'm in Sydney !) but
not in going condition. The consoles are easy but the power supply, disk
drives and software are difficult, probably because many were in schools
where they were networked. All I've seen were CP/M. I've never seen one with
basic but that doesn't mean they don't exist.

Actually, all SA390/400-type drives I've seen (which are nominally limited
to 35 tracks) can step to a 36th track without any difficulties, and
most can go to the 37th. The "36th track" trick was very common on
Apple ]['s, both for copy protection and for general use.
I've noticed that most decent data forensics tools (Anadisk, etc.) will
go the the 81st track on a 80-track drive, though I've never seen a
floppy that actually had data out there.

That's jibes with my hypothesis.

Yes, but it's been years since I've ODTed.

I know they are available for enough money. I was lamenting the fact that I
could have picked up a bootload for nothing and never had to buy another disk
again. I have a case of formatted disks and several cases of used disks with
data files from schools and at least one university lab that I can reformat
and test.
Mostly, I want to be able to extract the data *from* the floppies, not put
more data *on* them. I hope to stuff an 8" drive from my DataRam Q22 box
on an old 486 for data recovery, then back up my crate of PDP-8 and PDP-11
floppies.

Please, please, don't grab the CPU and let the disk drives rot. There
are way too many folks on this list who've made that mistake in the past
and now have a pretty box that they can't run an operating system
on.
The pictures are obviously very low-res, but here's my guess at what's
there:
The rack on the left looks to have an 11/04 or 11/34 on the top,
an 8/E or 8/F below it, and it appears that there's another 11/04
or 11/34 below that. (I could be wrong about the 11/04 or /34 identification -
they might be generic rack-mount boxes.)
The rack on the right has 4 RL01's or RL02's in it. (The one on the
top is a RL01, can't see any labels on the three below it.)

Hi again, I've been unable to send e-mail reliably for a while due to system
problems....so anyone waiting for email (Sellam in particular) you'll be
receiving something during the next 24 hours or so.
Anyway, I'm after a couple of items which I was hoping someone in the UK could
help me with.
First of all I've gotten the Apple bug again and want to get my Apple ///
going. It seems to work, but without a set of boot discs it's just so much
scrap....so can anyone point me at a source of said discs please?
Also, I have an HP-150 which I'm after a hard drive for. I did have a couple
of offers from the US last year, but due to system problems I lost touch with
the person concerned....that said shipping would've made the cost prohibitive.
So, does anyone in the UK have a unit that's up for grabs?
Thanks.
TTFN - Pete.

Hi Peter:
Thanks for taking a good whack at the spam. I have been trying do some spam
whacking myself and have lately been using the free service part of
http://spamcop.net .
I used spamcop on that same spam message and the spamcop results are found
here:
http://spamcop.net/sc?id=1116253&crc=178709
I would be interested on your thoughts of this SpamCop.net? Is it worth my
effort to parse and report the spam with it? How did it do on this example
of spam?
Just wondering if you have the time to comment.
Thanks for you time,

I don't think Alison means 11/23 and 11/23plus; the 11/23 uses a
dual-height M8186 (KDF11-A) board. But the M8189 was used in both
11/23plus (BA11-N box, IIRC) and microPDP11/23 (BA23 box). The difference
was just the boot ROMs, as she said.

While most of Y'all were at the VCF, I decided to spend my time in similar
activities and dusted off two projects I've been tripping over for weeks:
my two ASR-33's (more on them in another posting) and a Heathkit H-11 that
I rescued from a former employer a few years ago.
The H-11 was pretty goobered up from the previous owner. He soldered wires
right on the DLV11-J connectors, for example. He also cobbled up his own
CD slots for an RLV11 by extending the case out another 4 inches and wrapping
two pairs of Heathkit Q-bus sockets together. It was gross. I have the case
back together (except for the top, which he lost) and have been working on
the cards.
I discovered in my piles of CPUs that I have two M8189 "PDP-11/23plus" boards
with different ROM revisions. One has the numbers "SG8335 339E2" and
"SG8335 340E2" on them and behaves like the description in the handbook. The
other board is populated with "LM8451 183E4" and "LM8451 184E4" and comes up
with a much more interesting banner. It claims to be Rev 0.9 of a ROM set
for the 11/23plus, and after verbosely testing memory, tries to boot DU3.
You have the option of retesting memory, dumping a memory and I/O map or of
booting from several devices including tape, network and several flavors of
disk. This brings me to my next problem...
The Heathkit floppy controller is labelled "H27" on the white handle with a
silk-screened part number of 85-2183-1. If I put it next in the grant chain,
the 11/23plus hangs. If I put it at the end of the bus, the 11/23plus tests
and lets me try to boot from it. I have the cover off the floppy case and I
can see the heads load and boot. They drop to track 0, move around, read in
a few tracks, then unload and the CPU never prints out another thing. I
suspect that something to do with DMA or interrupts is hanging the CPU once
RT-11 loads into memory. I did pull all the chips (100% socketed) and test
them one at a time. Some failed on the first go, but passed after wiggling,
telling me that there is some oxidation on the leads. I pulled and reseated
everything and will try this thing again when I get back out to where the
H-11 is.
In the meantime, I am wondering if the H-11 floppy box is pin compatible with
an RXV11. I happen to have one here, but I don't want to fry something if
they are not compatible. BTW, there are three jumpers on the H27 - E1, E2
and E3. The card passed into my hands with E1 and E2 strapped, but not E3.
Finally, eventually, I want to get original stuff back into this box. I have
the DLV11 console board that came with this, I'm just not using it. In
addition
to the H27 floppy card, I have a Heathkit lineprinter card (unassembled) and
a wad of Q-bus CPUs from the LSI-11 up to the 11/23plus (nothing newer,
unfortunately). So the question is, what "belongs" in this box. Did it come
with an 11/03 "LSI-11" CPU? An 11/23 F-11 board? What did the H-11 use
for boot roms? A BDV-11? An MXV-11? A Heathkit board?
Thanks,
-ethan

The RXV11 doesn't do DMA, and while booting it may not need
interrupts. But after the OS is bootstrapped and is "going" it'll
probably start looking for interrupts.
The fact that the machine hangs solid when the card is where it's
supposed to be may be a clue that the it's permanently stuck interrupting.
Does the Heath machine at least have a "halt" button so you can
get down to console ODT ("@" prompt) and do further debugging from there?
