In Geos the whole OS was coded in 6502 assembler. Couldn't make an 8bit gui work with slowpokes like C.
GEM and TOS (as I understand) were partly host assembler (8088 or 68000) and part c. No commonality
under the hood at all.

Burning under windows is probably
not an issue - use something like
CDR-Win to make an exact copy
to an image file, and then burn that.

I don't know the specifics of RT-11s requirements
for the CD. I expect that RT-11 sees it as though
it were a hard disk of exactly that many blocks
(well 4 times the number of CD blocks because
of the 2048<->512 byte thing).
Many (many) years ago when I used an
LSI-11/23 under RT-11, we had a 40MB
drive that emulated 4 RL02 drives (or
some such). I don't recall if this
was done in software or hardware -
quite possibly it was a software driver
that came with the disk.
Why is 212992 magic? What do you do
to make this CD visible as 7 (or whatever)
disks under RT-11?
Essentially your CD is a stream of N
2048 blocks and is presumably seen by
RT-11 as such (at a sufficiently low level)
and then given meaning by some
software layer.
A typical method for generating
a layout with both ISO and
"other stuff" in logically separate
areas of the CD would be to start
by generating a binary ISO-format
file with just the ISO data in. The
first 64 2048-byte blocks (or is it
32?) are ignored by the ISO9660
standard - they are deliberately
not used.
Now create an empty image file,
the size of your CD. Overlay the
ISO image file onto this.
Now you slip the PDP-11
boot block in there and add whatever
else you need at the end in whatever
format you want. The ISO file structure
will be unaffected (so long as you tack
things on after its logical end).
What you need to find out is
RT-11s requirements in this area.
Actually doing this under W98
may not be that easy. Typically,
when I've done CDs that have
both ISO9660 and ODS-2 on
them, I've generated the image on
OpenVMS and burned the image
to CD using a PC.

Well, assuming you really mean DA15 (not DB15 :-)) then, yes, all you need
is a transceiver. The miniature type that fits straight onto the AUI
connector is best, and usually cheap and easy to find. After that, it's
just a question of having TCP/IP software.

At one point the RSX, TOPS and RT11 CDs
were all available as binary images. I know
I downloaded all of them and burned them to
CD with no problems. (Well, maybe a slight
issue with the RT11 one IIRC - I used W98
and whatever burning software I used
was not too happy verifying it ... seemed
usable though).
Tim does not seem to have any problems
with people downloading large amounts
of data so rather than ask for a CD, just
burn one.

You are probably thinking of "ex". But "ed" is a proper subset of "ex".
The classic answer to the question "point me to a guide" is
$ man ed
executed on any Unix or Unix-like system. If you don't have one of
those running, you can try, with your favorite web browser, a Google
search with the key words: unix man ed

Yes.
Boot to non-timesharing then use ED (sorry no other choice usually)
to edit passwd file. set the Root user password to NULL (no characters).
boot to timeshare level and then log in as root with no password.
My ultrix manuals are burried or I'd give more detail.

FWIW, I think a central bug listing is a good idea.
Caveat on my opinion: I do not currently have any PDP-11s operational,
although I have several that could, conceivably, be put into working
condition on short order. I.e., I'm not currently running RT-11, although
it's on my List of Things to Do.

I found a TI data book dated 1971 and it doesn't even mention 12xx ICs. It appears that by 1971 TI had switched entirely to the 54/74xx series. I have a couple of even older TI books if I can find them.

Hi,
this weekend, we have been unsuccessful trying to get one of the ancient Unix
versions (V6 or V7) to run on a PDP-11/34. The plan is to have an ancient
PDP-11 on the VCFe in Munich running a proper version of Unix.
THe machine has two RK05 drives, RX01 floppy and a TS03 tape drive. Our first
problem is that we have been unable to find or make up a TS03 bootstrap.
We considered using RT-11 to transfer disk images to RK05 drives, but we could
not figure out how to get the image straight to the disk without having to
store it in an intermediate file and writing a RT-11 program to access the
disk sector-by-sector.
We have a lot of hardware at our disposal, so we took a Emulex TC12 Pertec
tape controller from a 11/44 (the 11/44 would also be nice as demonstration
CPU, but it has a SMD disk controller for which we have no drives). Not
having any documentation on the TC12 we just put it into the 11/34, but it did
not work (bus error LED lit).
So we're kind of stuck. Any ideas, hints or pointers (especially to a TC12
print set) would be greatly appreciated.
Thanks,
Hans

Sellam, why do you insist on labeling people with terms such as "silly" and
"lazy?"
Have you considering taking the easy way and suggesting that they might be
mistaken?
Also, do you still want this Amstrad 3" drive or shall I repost it to the
list? It's been several months . . .

The point is, I can't see a real difference between a ROM chip
and a decoder + gates. Electronically they're much the same
thing. Physically, to change the program, I have to use a
soldering iron. It is _not_ clear to me why one is called firmware
and the other called hardware.
How about .. Hardware is the physical part(s) of a design that can be
seen, touched, crushed, thrown, weighed etc. Firmware is the idea
statically implemented in that hardware.

You get one that has the interface you need, but I think you
can swap interfaces; e.g. I've swapped a single-ended SCSI
interface board into one that I got with a differential SCSI
interface. Note that the interface board is screwed to the
back plate which has the cutout for the connector, so if
you get a different interface board you may also want to get
the appropriate back plate for it.

I haven't looked inside one with a Pertec interface, but the SCSI
interfaces expect to plug into a flat cable that is in the base of the
drive and I expect the Pertec interface would too.
There's also a four-slot card cage in the right side of the drive,
accessible by removing a top cover. The boards installed in this cage
make a difference too. Later drives have only three cards installed
(the read/write/PLL boards and formatter board were replaced by a
single board).
7980A and 7980XC are HP-IB-interface drives sold into the HP
minicomputer markets. The XC suffix means the drive was sold with a
variant board that supports data compression (meaning you can write
tapes that are only readable by other 7980XCs).
7980S is the same drive with a SCSI (single-ended I think) interface,
sold into the HP minicomputer market. At one point HP offered a
field upgrade kit to change your HP-IB drive to a SCSI drive.
There is also a variant board that supports 800 BPI (in addition to
1600 and 6250). I believe that 800 BPI and XC compression are
mutually exclusive (you can't have one drive that does both).
7979A is an HP-IB-interface flavor of the drive that supports neither
6250 BPI nor data compression. I'm not sure but this may simply be a
different-variant board as well.
88780 are drives sold outside the HP minicomputer markets, including
OEMs like IBM, Sun, and Tandem. Of course the OEMs came up with their
own model numbers.
I have some notes that say data compression was option 400 and 800 BPI
was option 800, but I'm not sure whether this applied to a 7980 or
88780.

That depends on what he meant by "make ISO images of cd roms."
I read that to mean "I want to make a raw copy of the disk, and
I'm just saying ISO out of habit." You obviously read it to mean
"I want to make an ISO image out of some files I've got so that
I can burn it onto a CD."
So which was it?

No; assuming you've got files on a Linux filesystem, you use
mkisofs
to create the ISO9660 image file (with Rockbridge extensions).
Then you use
cdrecord
to burn the image onto the CD.
To capture an existing CD-ROM into an image file, most
likely, Chris is correct, but I haven't gone that direction
yet.

Hi all.
I need some advise.
In 3 weeks time Edward and I drive to Italy (some 1100 km)
to pick up several PDP-11/70 parts.
I have the oppertunity to drag 2 RM03 massbus drives and
some packs back home. Now I know already that these drives
weigh about 200 kilo, have a disk capacity of 67 Mb and
are really power-hungry: at 240 V/50 Hz. stand-by is 3.5 A.
running they consume 11.5 A. and rush-in current is 22 A.
My experience is that DEC tend to give high numbers for the
power consumption, but do these drives eat that much current?
Are they worth preserving? Or should I leave them where they are?
Next to the 11/70 is looks great (IMHO) but I would love to hear
some opinions from other collectors.
- Henk.
I see lots of references to these drives...
Do they possess multiple interfaces, or do you get
one that has the interface you need?
I've seen one with an HP-GPIB interface connector
on the back, and was wondering if I pull that rear
cover off, will I find a set of Pertect interface
connectors hiding there? Or is that simply a different
model?
Thanks,
