Here's a possibly stupid question...
I may have mentioned it earlier, but I got a copy of PDPXASM and I'm playing
with it. Just pitching code at the 11/83 to see what I can make it do...
Anyway, I'm playing with telling the RL02 what to do.
Push the head around, write things, etc...
Anyway, Is there a way to, given the the sector number, figure the head/cylinder/sector? Also, is there some mechanism to keep me from screwing up and sending
the heads below track 0 or past 512?
By the figuring CHS question, I mean this: I want to make a single routine
I can call to position the head whereever and dump a sector to disk, but I
don't want to have to know the disk geometry to do it. I pass to it
a unit number, RAM start address, and a sector number. Now how do I divide
the sector number to get the C/H/S? And I don't want to have to use
floating-point to do it...

Some days I can't even think straight... What I meant to convey is that
people should take responsibility for their data. If they care, they
should do something about it (even if it means calling the neighborhood
guru.)
However, not doing that doesn't give anyone the right to turn around and
use that information... If I don't pull my shades, you don't have the
right to make a porno (horror?) movie of it. But, if I care about anyone
seeing my fat carcass, I should pull down my shades.
I do agree with the idea that we, as collectors, should hold ourselves to a
higher standard. If we want folks to continue to pass machines our way, we
need to make sure they feel comfortable about doing it. (Just as I
wouldn't look up what drugs someone is getting from Long's, or what medical
problems someone had when I was working with Aetna Health Plans; I want
them to feel comfortable hiring me again in the future.)

So happens my XT is a Leading Edge model D. It's a good solid and slow
system but it works so well and is small.
I got mine from the first owner who bought it new when it first came out.
Prints for it would be nice.
Hacks (plugins) applied to it over the years:
Used the basics disk controller that is on the mother board to run a
720k 3.5" and 360k floppies.
Installed a 1.44/2.88 floppy adaptor so I can run 1.44 floppies.
Installed 1002 HDC and st251
V20 (to run 8080 software)
My Inboard386pc was in that one for a while.
The machine is useful for many things as its so basic and clean clone.

I might have a DHV11 manual around, I'll have to check. I do have a
board in an old uVAX II. Do you need anything in particular? Like the
CSR and interrupt switch settings? As I recall, the Q-bus DHV isn't
quite the same as a the Unibus DH11, but it does use DMA, much faster
than a DZQ11. The DHV11 uses floating CSRs, do you know how to set
them? (I assume you are going to use VMS)

If anyone has need for Leading Edge parts, software, etc you can obtain
what you need at http://www.primenet.com/~fwagner/le/leading_edge.html
since Leading Edge is out of business and no longer supporting anything.

Did anyone ever get one of those? I guess they were mostly for music, but

I wonder if they exist today.

(reminiscing)
I have the following for those interested:
Two 19mb and a 10 mb Computer Memories hard disks 5.25" full height all
have very bad stiction and and two are bad...
Why would anyone want these? The logics are good and they have a R6522
and MC6803P in sockets. The 6803 is a 6800 with a few enhancements like
internal ram, timer, serial and parallel IO and also bus for external
program rom and ram.
Or maybe someone would want to see the inside of a hard disk.
If interested contact me.

The way I see it, if they want to make sure the data doesn't get out, they
need to delete files.
But, I wouldn't take someone's personal spreadsheet of their monthly
finances and post it on the 'net, either.
What I've done in the past is look at it, and then generally delete it.
Why? Because it's generally boring as hell.
Now, if I came across some Hubble stuff, and I knew how to use it/what it
meant, I'd probably hang on to that. But only for my own personal
use/interest.
As I see it, when someone gives you a computer with data on it, they're
giving you the data as well. However, they're not giving you license to
sell that data to the Weekly World News.
I'm working with Long's Drugs, a chain of pharmacies on the west coast. If
I poked around in the store databases and told you that, say, Grace Hopper
was taking birth control pills, that would definitely be an invasion of
privacy. (and would likely get me thrown in jail.) However, there's
nothing wrong with telling you that there are 13 women who go to the
Serramonte store to get birth control pills.
Same thing with e-mail, word processing documents, spreadsheets and the
like. If your buddy Joe gives you his old computer, you should go poking
around his old e-mail or wp files. If, however, you get a computer from
company x that was used by employee y that you don't know, the data is only
statistical.
I think generally, it's a moot point because it's usually too uninteresting
to keep around.

As one facet of this, we might consider what people would do with
their old systems, if they even got the *impression* that their
private information might be read by a new owner. They might
prefer to totally destroy the machine than to take a risk like
that.
In this respect, the actions of each collector impinges on all of
us; it may take only one publicized breach of privacy to reroute
a lot of old boxes to trash compactors that would have otherwise
gone to collectors. It wouldn't even matter whether it was someone's
personal love letters or a company's records. The impact would be
the same.
With this in mind, I suggest we adopt the common policy of wiping
everything but obvious system software and such. There will always
be the practical matter of determining which is which, but it seems
best for all concerned to religiously respect privacy, irrespective
of whether it is that of an individual or an organization.

A friend I work with donated the following book to my collection today:
VIC-20 Interfacing Blue Book, by V.J. Georgiou
Anyone seen this before? It is an incredibly neat book on hardware
projects for the VIC-20, including such things as Liquid Level Sensor,
ram expansion cards, eprom programmer for micromon, ring detector and
lots more. It is overall a superb text. If you would like more info,
let me know. I'm not interested in getting rid of the book but would be
willing to share via scans or photocopies. ;)

No it didn't have splines in the kit. The only recent product that

I have had some disks for a long time and would like to give them to
someone who has a need, a use, or even a clue as to what they are.
Three have hand-written labels
1: XYLOGICS 450
XENIX DRIVER
503-450-405
tar cvbf 20 /dev/rdvfo
DCM 7/86
2: XYLOGICS 450
XENIX utility
503-450-405
tar cvbf 20 /dev/rdvfo
DCM 7/86
3: XYLOGICS 472
XENIX DRIVER
503-472-405
tar cvbf 20 /dev/rdvfo
DCM 7/86
I can't do anything with them on a PC, Norton won't let me see a
thing. I can see the sectors with my TI-99; #1 might not have valid
data, but 2 and 3 do. The second line of the labels might be 905
instead of 405 and rdvf0 instead of rdvfo. There may be nothing useful
on the disks, but...
The other disks are original (not too fancy) Intel disks:
4: SYP 286/300 DIAGNOSTICS 19 MB, #1A
DS/DD IRMX 86 FORMAT, 48TPI
PART NO. 174133-001
(c) 1982, 1983 INTEL CORP.
May not be copied without a license. Refer to price list for copying
fees.
#5, #6, #7 and #8 are identical except for the disk# and the part#:
5: #1B, PART NO. 174134-001
6: #2A, PART NO. 174135-001
7: #2B, PART NO. 174136-001
8: #2C, PART NO. 174356-001
If you want them, send an address, if they're not notable, I'll
reformat them. All, with the possible exception of #1, all have data
of some kind.

I have aquired many computers with old data on it. My theory is, "I won't see
this guy again so I'll read his stuff anyway." I know it breaks his privacy,
but it is not like I am going to start e-mailing all his friends, that would
just be a waste of time. Any games or programs that I should not own (i.e.
sensative material or beta's of software) I keep only because of the novelty.
Those are my two cents,
-Enrique!
I know this is not on topic, but I thought you guys could help. I
recently installed Red Hat 3.0.3 (release, not kernel version) on my
computer. It runs great and I am satisfied, but some games and programs
can't seem to find certain libraries, though the libraries are there and
in the right place. An example is "Unable to load 'blablabla' ; Exec
Format Error" or "Unable to load 'blablabla' file not found". Keep in
mind that all of this was on the Red Hat cdrom, so I doubt it's the
wrong format. I also tried replacing the libraries with ones that I have
used before and they worked. This did not help either.

This weekend I came into a real pile of stuff I classify as I would ahve
liked to own it if I could have affforded it when new.
2 California Computer systems 2200 boxen both with external 8" floppies
and one with an 8" hard drive (DISCUS). About 50-60 boxes of 8" floppies
33 of which are CPMUG and SIGM archives. Plus Docs, docs, docs. These
seems to be intact and I expect they work buyt haven't powered them yet.
3 Visual 1050s, a pizza box with two floppies, detached keyboard and
monitor on top. Two have hard disk boxes on the side. Also docs out
the ears. Also a mountain of disks. All three work.
Of the document excesses in the pile I must have 5 sets maybe more of DRI
CP/M-80 and some CP/M+ docs plus redundant copies of wordstar, multiplan,
Cbasic, and some DRI graphics tools. It filled the back of my toyota
pickup and the cab. My current task is to inventory what I have.

Much more likely to be Imperial, on American equipment. Some sets go up in
bigger steps than others, though; perhaps the one you need is just "missing".
I have a few sets like that :-)

I have a new, in the box, AST-5251/11 setup that allows a PC to
communicate with an IBM 34/36/38 mainframe (?). It includes a thick
manual, 5.25" and 8" floppies, twinaxial to adapter card cable w/tee,
and the adapter card for an ISA slot. Still with the original overbox
that shows all the features of this beauty.
The box states that the card is an 8 bit, DMA selectable for PC/XT/AT,
selectable interupt channel, on board high speed 8X305 processor,
5251-11/5291 or 5291-1 display terminal emulation, host addressable 5256
printer support on the PC's printer, concurrent host and PC sessions
with hot key assist, bidirectional file transfers, and more. This is the
enhanced version.
I have no use for this and many of you are into connection to mainframes
and minis, so make me an offer, whether it be cash or trade for PC
compatible items.
Also have a big box full of S/36 5.25" disks and manuals. Will post
those as soon as I go through and inventory them.
