Hi. I recently acquired a 1950's vintage Gibson GA-30 guitar amp. Never
having owned a tube-based amp before, I'm clueless about the proper way to
use this amp without abusing it (and it sounds great, so I want it to last
a long time! :v) .
For example, should I allow the tubes to warm up for a few minutes before
playing, and are there any special precautions I should follow after
playing (i.e. do I need a cool-down period before powering down?). Any
advice would be much appreciated. A quick Web-
search didn't reveal much except prices on used equipment.
Thanks!
Mark.
Hi,
Just a few possibilities.
Some hard drives will cause the above message if the 0 track has been altered (written over) linux is well know for this and the only way I know to resolve this is to low level format the drive. A lot of 386 and early 486 Award BIOS machines have an option of hard drive utility. If you do you're all set. I chose a 3 for the interleave value.
Try and boot the computer from the floppy, then run fdisk to see if you can reset the hd.
Check to see if any of the jumpers are missing from the pcboard part of the drive. Try typing the drive manufacture and model in Alta-Vista and see if the specs come up. That usually works for me.
If you have no set-up disk..... try the following on boot to get to the setup up Menu.
1) Hit CTRL+ALT+S or
2) Hit CTRL+ESCP or
3) Hit DEL

Try setting the scanner on either grayscale or monochrome, 150-200dpi. This
is what I use when scanning any tyoe of documnentation. I have an Artec

Sorry about that. Wasn't paying much attention and rather assumed
that the advertiser had set the response address to itself. Glad I
also neglected to attach the images. (If you want to see them,
they're on my home page and no, I didn't create them).
OBclassic: anybody got a copy of TRS-edit (a vi clone) for the Radio
Shack Color Computer that they're not using? The current GNU
equivalents seem to crash my system during the compile, I think that
they're too big for a 512k OS-9 system, or else I've got a hardware
memory problem -- and the CoCo 3 memory kits are rather hard to find
these days.

Hi Russ ("alice"),
Well, once again I high bid on the thing -- this time it closed at $51.01 --
hey, if this keeps up, maybe after three more auctions, he'll give up and
let me (as high bidder) get it for $17.38... :-)

let's just hope you can login as root.
what the message you're seeing says is that you may have forgotten to
activate the partition, which you must do in all cases where you don't use
the "entire drive" in your primary partition.
try that, and see if it doesn't fix your problem.

ISTR that the IBM PC had it at decimal 156. I have seen it replace $, #, \

The 8bit IDE looks like the 1002WA ISA 8bit controller. The 1002HDO host
interface however does not. In the 8bit worlds there seems to be three
different schemes.

It's not easy. The host interface only allows for a few address lines and
8bit IDE is both scarce ands strange. For practical use and the difficulty
of interface doing a 16bit IDE converter is more practical. The real
problem is you no matter what will be writing a bios for the kaypro.
People with the correct controller and MFM disk are already faced with
things like the drive needs replacing and there is no formatter or partition
utility if the drive is greater than 8mb.
Check out TCJ #80, a 1002WXA or similar is easy as pie to interface to
a 8bit bus (like the host adaptor port). and they are common enough as
they were about the best thing for the XT class. It means using a MFM
drive but, st225s and st251s are common and there are old 3.5" mfms that
work good with those too. The bios problem remains though.
Oh, 40mb would have to be sliced (partitioned) into 5 8Mb logical drives
under cpm. I know as my SB180 and AmproLB both have 20 and 45mb drives.
Under CPM even 5mb is a lot of space and a 1.44mb floppy is very roomy.
The 781k format allows me to have all of my most common utilities and
programming tools on one drive and work space on another. That good
enough.

Seems the bidders are losing interest, not to mention he's changed the
title of it where it doesn't reflect the word Osborne (so a search
doesn't show it). There's less than 8 hrs on it and the high bid is
$12....
The guy that did the high bid last time (Imsai) bought my Kaypro 2X and
I asked him if the seller made a deal with him since it came below the
"reserve" and believe it or not the dummy seller let a $400 bid slide.
It's listed on e-pay right now as

I am having a little trouble with my TRS Model IV . When I boot off of the
TRSDOS system disk, the system prompts for the time and won't go any
farther. When I enter the time, it clears the field and prompts again.
The computer works just fine with all my other software so, I suspect the
disk is corrupt. If anyone has an extra copy of TRSDOS 6.x laying around,
I'd really appreciate it.

Consider:
Sony Mavica: $660
Take picture, size, and upload.
Scanner (Cheap) $50
Cheap 35mm Camera $50
Film - dollar or two per roll
Developing (Cheap) $4 per roll
ScanTime (I got it down to 4 minutes per pic)
So, for 24 pics:
Sony Scan
$660 $105 Equip/Supplies
$ 0 $ 96 Scan time (at $60/hr)
$ x $ x Size/Upload (same for both)
---- ----
$660 $201
Now for multiple rolls (say 5):
Sony Scan
$660 $125 Equip/Supplies
$ 0 $480 Scan Time
---- ----
$660 $605
The more you take, the more cost effective it becomes. (Mind you, I don't
know how you value your time, but waiting for a scanner hardly seems a good
use of my time).
I know I've taken a lot more than 5 rolls worth of digpics -- Take a look
at <http://www.sinasohn.com/urbadv/phalbum.htm> for example. And I've got
a lot of classic computers to take too.
The Mavica is not the cheapest DigCamera either. If you go for one of the
less expensive models, your costs go way down.

Anyways the Europeans got it right you are the one writting the date

Hmm. I'm just flipping through some issues of the First Basis Users
Group newsletter, and it looks like Basis in Scotts Valley was out of
business by October 1983 (with its inventory being bought by an
"investor" and re-sold through a couple of other companies on west and
east coasts), and other attempts at establishing a distributorship
through other US-based companies met with varying degrees of failure,

And it looks like there was some sort of Basis in Germany into at
least 1987 when I run out of newsletters.
But yeah, I have one, a friend has one, he had another one when he
lived back east, I've seen others go by, and they were very nice
machines, superior to Apple ][s in several ways. So I don't think the
108s are that uncommon in the US. A 208, now....

> so don't get the idea that you can

My parents have 3-phase electricity at home, but I don't (yet). But I
think it's more common in the UK than in the US. (BTW my parents have a
16th century farmhouse which they heat electrically during the winter.
Maximum load we've measured, 36kW.)
I am told (I think it was Toy Duell first pointed it out to me) you can get
reasonable 3-phase using a largeish induction motor (say a mechanical
rating 2 or 3 times the electrical load you want to connect), without a
mechanical load: wiring one phase to ground, a second to line, and the
third to line through a capacitor for an approximate 60 degree phase shift.
The induction motor will also act as a generator, and produce enough emf to
tidy up the phase relationships and voltage imbalance. But be warned - you
will not have the right voltage, and one of the phases (rather than the
star point) will be at ground potential. A bank of three single-phase
isolating transformers should do the trick if either of these is critical
(a single autotransformer, upstream of the converter, will also work if
only voltage is critical.)
Also be warned. I am confident that this works _in theory_ but I have
never tried it.

I don't have any ISA cards to give away, so I offer you $10 per card.
>What's a slave card?
A Slave S-100 card usually have some memory, a CPU and at least a RS-232
connector. What would happend is that when your system started up. Your
master CPU on the S-100 bus would load the memory of the slave cards with
something, like the slaves own version of CP/M. You could have as many of
these things as you box could fit. There were a number of way I/O to the the
users of the system could be accumplished. One was route all the slaves I/O
to the user throught the the s-100 bus to a I/O card connected to the users
terminal. The other and more tipical way what to have each user have their
termianl connected to the slaves RS-232 port. The drawback to this method
was there had to be a bus master handling all bus traffic to an from I/O
devices such as disk drives for each of these slaves since the slaves could
not do it themselves.
Compupro made a Z80 slave card that supported between 64K and 256K or RAM
that had a RS-232 port. If I recall correctly you could only put 8 of these
on you bus. But you could hack them to put as many as your bus supported.
This is the type of board I am looking for.
There was another method of placing multiple CPU on your bus. That basical
ment building a Single Board Computer (SBC) that could use the S-100
Temporary Master Access (TMA) hand shaking. The S-100 supported up to 16 of
these TMA on a bus. The advantages is the TMA's tended to use the bus more
efficiently comparied to slaves boards with requried a bus master present
servicing them. I don't know who use to make SBC that fully IEEE 696
standard for TMA access but do know that they were out there.

It's difficult to give you information about wirewrapped boards. What,
exactly, did you want to know. You're probably right in that the backplane
is S-100, since that's what the Wunderbuss was. It's clear what the 8"
floppy drives are. I certainly can't tell you what the punch/reader is if
you can't tell. Mounting a motherboard on plywood was an easy way to do
things if you knew well in advance that you needed to "get at" the boards
with 'scope probes, etc. It saved extender boards and the associated
problems.

I'm specifically looking for a power supply for a Commodore 64, but I'd
also like to pick up some old documentation, too.
In particular, I used to have the "Programmer`s Reference Manual" and a
book that mapped all of the memory locations and described the kernel
routines in detail.
Any info would be appreciated. I'm in the Pittsburgh, Pa area.

Actually, I meant to say "Date" not "Time".
Can't blame this on the europeans. "02/04/99" should work either way.
Actually, I assumed that it was operator error but the other apps work OK.
Since the other software works properly (IE: Profile III), I "think" we can
eliminate hardware problems. And... since the dummy behind the keyboard
(Me) is functioning correctly, that only leaves the software.
Another question: There are several sites on the net that have Model III
and IV software on-line. How do I get the software from a modern Pentium
(surfing machine) on to a diskette that is readable by the Model IV?
I also have a TRS-80 TL2 with 5-1/4 and 3-1/2 inch drives. Can I download
the software on to a 720K disk and then transfer it 360K using the TL2?
Thanks...

Try entering a 1998 date. The year '99' to TRSDOS may be "special" in the
sense that they code it to mean "date not initialized". If this fixes it
then you've just entered the Y2K Zone ...

The problem is that TRSDOS 6 will not accept _any_ date after 1987.
That applies to 6.0, 6.1 and 6.2. Try giving it a 1986 date and see
if it takes it.
Supposedly, it is still possible to get the update to TRSDOS to fix
this from Tandy, however it is not necessary. Go to Tim Mann's web
page, where he has available for download the final release of
LS-DOS, which has the fix.

Oh, and while you're there, and if you run Linux or any other

Well, FWIW, I'm just posting this from the Heath reflector if anybody's
interested.
Apparently, the fellow feels his work is worth something as I think the
prices are a bit high. He doesn't actually realize the value of these
things, so go easy on him. (I do not know him. I'm just a silly engineer
myself and probably can do as good of work ;)
Don't know exactly what he means by "detached keyboard" in the H89/H8

keyboard end of the H89 case, place nice looking covers over the openings
and run a suitable ribbon cable between.

I also understand a one time some use to make S-100 SBC that met all the

enabling someone to put up to 16 of them on the same S-100 bus.

Okay, it's not quite a classic since it's only 7 years old, but does anyone
know whether the simms inside a declaser 1152 are standard 30 pin mac simms
or if they're something wierd? I desperately need to upgrade my old declaser
- it keeps running out of ram printing things and Kinkos wants $.49 US per

does anyone out there happen to have the 2 meg expansion (part number LN07X-UF)
for the thing?

And the NeXT Cubes. I've never had a problem with the machine hanging when

Tandy may have *made* the m100; Kyocera *designed* it. I think Tandy
redesigned it (tweaked it) into the 102; they probably did the design
(based on the original Kyocera design) of the 200.
FYI, there are 9 versions of Kyocera's design:
Kyocera KC-85
TRS-80 Model 100
TRS-80 Model 102 (mostly the same as the 100, only lighter and cheaper)
TRS-80 Model 200 (clamshell, with larger screen)
NEC PC-8201 (Japanese version, with Katakana? charset in ROM)
NEC PC-8201A (American version)
NEC PC-8300
Olivetti M10 (American version)
Olivetti M10 (Euro version)
Not related, but possibly mistaken as such:
TRS-80 Model 600
NEC PC-8401A "Starlet"
NEC PC-8500
Olivetti M15
I don't know if Kyocera ever came out with anything after the KC85.

like many of them came from Telex's office in North Carolina. Many of them
look like reports of test on different models of equipment, equipment

Don't confuse sampling noise with quantisation noise. Quantisation noise
is due to the replacement of an analogue value by a digital representation
not exactly the same; it is reduced simply by having more bits of precision
(there are other tricks, including things involving oversampling, but they
only cloud the issue).
Sampling noise is present in a sampled waveform whether it is a sequence of
digital numbers or of analogue values. It arises from the deviation
between the original waveform and the sampler output (with no filtration at
all this is a series of steps) at the intermediate points between samples.
Oversampling interpolates intermediate samples, and uses a filter to reduce
the sampling noise due to not having known what those intermediate values
should have been.
While I admit that the linear interpolation I described is a rotten
oversampling filter - it was only mentioned by way of an example - the
mathematics are the same whether you use a digital computer to generate the
digital numbers at your oversampled points or a switched analogue circuit
such as I described to generate analogue values at the intermediate points.
This analogue circuit can also (theoretically) reduce quantisation noise
even compared with digital oversampling, since the intermediate values are
not limited to the precision of the DAC. In practice, quantisation noise
probably is probably slightly higher, since the intermediate values are
limited to the precision of the resistor networks that derive them.
So why does this sort of analogue filter not reduce the sampling noise at
Fs/2? If it introduces noise at higher frequencies (which I agree it
does), this is because the noise arises from conversion of samples to a
continuous function, not from conversion of digital to analogue.

I have met delta-sigma encoding, but I never managed to work out how you
get the sampling rate down to a manageable value. Since we're getting a
bit off topic here, could you post not an explanation but a reference to
somewhere I can look up this particular aspect of the problem.

Kevin, isn't there a way to completely hide this archive from any search
engine? I'm no web weenie so others here who are should jump in and answer.
Links that ClassicCmp folks put on their pages to the archive do, of
course, blow the cover. What if we just have an unannounced or "secret" URL
for the archive? List members could be given it and a note placed
prominently on each archive page stating this is priviledged information
and not to be publicly released because of unprotected email addresses or
something. List members will just have to write the "secret" URL on a
Post-it note and place it on their computer or tack board. Passing of it to
new members or those of us who have lost the addr. would be given it only
by private email.
Well, it's just an idea.
This list is, in my opinion, a very significant source of technical and
anecdotal infomation about our old machines the likes of which probably
could never be found elsewhere. I've learned so _very, very_ much from many
of you since 10 December, 1997 when I joined. Witness the recent IBM 1130
thread. We found more info relating to them and a working system in
Germany! I've got DEC gear in my collection which several have been helping
me on it. I really hope I helped a few of you too.
It's been discussed here before, and again I'll state that it's a pet
peeve, that some really important tidbits of info on our classics is not
found by any search engine that I know of. So there seems to be some way
the pages are hidden. In this case of securing our ClassicCmp archive's
privacy, the pet peeve is hereby released :-)
I can always use the 170MB (and now growing at a rate of about

I'll send you a vote privately but I do want to say the archive is a very

I think nearly all of us feel access to it is needed no matter where it is

New stuff: I went scrounging yesterday. I bought stack of new Televideo
manuals. I got:
(book 1) Televideo TS 802H Computer System Installation and User's Guide
with the quick reference guide, packing list, Digital Reserce lincense for
CPM, errata sheets, customer quality survey, F1-40 print sample, a brochure
>from TRW about maintenance service and several addendum booklets.
Looks pretty cool. Has anyone got one of these that they don't need?
(book 2) Operator's Manual Model 950 (new in sealed package).
(book 3) Televideo TS 800A, TS 802 and TS 802H Maintenance Manual. This
is THE best maintenance manual I've ever seen! It not only includes the
maintenance information and schematics but also spares kits inventory
listings, complete parts lists and prices, parts specifications, board
drawings, circuit descriptions and theory of operations, timing diagrams,
etc.
(book4) Televideo Model 925 CRT Terminal Installation and User's Guide.
(book 5) Model 925 Maintenance Manual. If anything, this one is even more
complete than the one for the 802! It even includes the original Rockwell
Data sheets for the 6522 VIA, 6545-1 CRT controller, and a prelimiminary
data sheet for the Intel 8048H/8048-1/8035HL/8035HL-1 8 bit microcomputer
ICs. It also includes another copy of the CRT Terminal Installation and
User's Guide, a Terminal Troubleshooting Guide and additional service
bulletins and sales literature for the Televideo terminals.
I also got several boxs of CPM disk but I haven't sorted them all out yet.
I haven't found the Dapple computer that I spotted several weeks ago but
I found another one!!! (At least this one is clean!) I'll give details when
I've had a chance to look it over.
I also bought an Apple IIc in a 19" rack mount! It operates a gas
analyzer sytem and was put together in the UK. I haven't picked it up yet
so details will have to wait.

Dual tarriff (?sp) is quite common. The most usual scheme is called
"economy 7" which charges about 14c US per kWh during the day and somewhat
less (I think it's less than 5c - sorry, I am not in the UK this week so I
can't check) for a seven-hour period starting at midnight +/- one hour
(exactly midnight on older installations). Some circuits - mainly heating
- are controlled by the same timeswitch (older installations) or radio
receiver (newer ones) as the tarriff selector on the meter.
It is said that many night clubs use economy 7 tarriff despite no heating
load...
Other schemes exist. One called "heatwise" also gives you a couple of
short periods of cheap power during the day...

It does sound like what I thought it was...
But remember, the disk may not be a total loss... many, if not most, of
the files are most likely still there (I'm expecting that sysgen simply
overwrote the beginning of the disk with each of the .OBJs... so the
amount of corruption would be no more than the largest .OBJ produced.
So, later directory segments would be okay, and there would be sufficient
info in them to recover those files. Earlier files would still exist,
following the directory... remember, they are contiguous files, so if
you find the start of one, you can get the whole file back.
There used to be a utility someone wrote, ndump, which looked at the
first n bytes of each block and reported on them... that way you could
figure out at least where your ascii text/source files were... and RT
provides commands which would allow you to grab just the blocks of the
disk needed to get a file...
It is possible, just procedural and time consuming... but if there is
information which is important enough, it is worth it...

If you can find the beginning and end of the file... you can probably
restore it from the corrupted disk in its entirety...

Any retrocomputing facilities in Hannover or Berlin?

There is the Nixdorf Museums-Forum at Paderborn, which is not too far from

Russian machines; mechanical calculators and telephone exchanges;

Look at http://www.hnf.de for more details.
I also recommend strongly the "Deutsches Technik-Museum" in Berlin.
They have a small, but significant set of exhibits:
- Replica of Zuse Z1 (1936), built by Zuse himself, mechanical computer,
operational;
- Zuse Z23, first transistorized computer by Zuse, I believe also operational.
- several other less prominent computer exhibits
- quite a selection on history of the electron tube and telecom
Normally the machines are not operated. I understand that upon special
request an appointment could be made, and a knowledgeable person
would come in and operate the Z1 and/or Z23.
Contact person is Hadwig Dorsch, details see http://www.dtmb.de
A pity that Munich is too far out of your travels - the Deutsche Museum here
also has quite a selection, but nothing live.
Hope you will enjoy your trip

A few weeks ago we were talking about the Sanyo 550 series and someone
mentioned one of the alternates operating systems that supported 80 track
drives in the 550. I said that was DS-DOS by Michtron.
Today I found an old Sanyo disk package with four disks for the 550. One
of them is DS DOS 2.11, one is InfoStar, one is MailMerge/SpellStar and the
other is a disk of misc utilities. The first three are original disks. In
additon, the InfoStar, MailMerge/SpellStar are Sanyo labeled disks that
came with the 550. If anyone wants them, trade me something I can use and
they're all your's.

You must have changed voltage long before we did then - we went from
415/240 V to 400/230 only about 5 years ago. Like with you, people still
talk about the old voltages, and my voltmeter still reads 248V...
(BTW it used to be 240V +/- 6%. It is now 230V +10% -6%, so electricity
companies haven't had to change anything.)
A few rural installations are only given 2 phases of the 11kV distribution,
rather than all 3. This means that a single phase transformer is used,
rather than a 3-phase transformer (Yes, I know, in the US you often get
poles with three single phase transformers hung off them). Usually this is
240V, but sometimes 480V centre earthed is used, the two sides supplying
different houses. Apparently some farm machinery operates on 480V single
phase, but I don't think much else does.

Hello Frank, Eric, Sam, Stan, and the rest of the list,
Thanks much for your interest. I replied to the responses (there were six
counting yours -- I'm impressed!) in the order that I received them. All
the manuals I referenced are now spoken for.
FWIW, the HP Customer Support manual went to Jay West, and the 9825 books
to Anthony Eros (he actually has a 9825 he needs docs on).
Thanks again to you all for your interest. I will continue to keep an eye
out for other 'classic' docs and goodies.

If you interested in a PET please let me know.
Anybody in Toronto that could check the units out for me?
Any idea on the best/cheapest way to ship to Boston, Mass?
I'll post more detail when I get them.

Sounds like the Andromeda ESDC I have in my machine, with an ESDI

another partitioned as one large disk (still identified as an
RD54, but at 680 MB)
Anyway, its hard to diagnose directory problems from a distance...
I'd need to see a dump of the first 68 blocks (0-67).

Hi. I have some ADAM software, but very few of the dreaded high-speed tape
cassettes to duplicate it onto. If you can send me an ADAM cassette, I can
dupe what I have - email me off-list if you're interested and I'll dredge
through the storage closet and see what I've got.
I frequently see the ADAM joysticks at the local thrifts; I can pick some
up for you if you want - again, email me off-list.
If you called Coleco, I'm sure their response would be either:
"Sure, we've still got 20,000 unsold units in the warehouse" or "Send your
computer, in it's original packing materials, to one of our convenient
repair depots ... "
Cheers,
Mark.

I agree with Tony. From an audio point of view, chips vs. valves (tubes,
for those colonies who've forgotten how to speak English) should make no
difference except in the analogue sections. On the digital side they have
no more than old computer technology hack value.
That said, oversampling and filtering is _not_ hard. People nowadays think
only in terms of digital, discrete working and analogue, continuous
working. IMHO the place to do oversampling is in between - in the
Analogue, Discrete domain.
How: Make several A-to-Ds (or one and some sample and hold circuits if
you're a cheapskate). The simplest case is linear interpolation which uses
only two. I would envisage precision ladder networks or something similar
for these. Call them A and B (and C, D, etc.)
Have some analogue circuits which use analogue summation techniques to
derive (say) A, 0.75A+0.25B, 0.5A+0.5B and 0.25A +0.75B. Switch between
them. You now have 4* oversampling, with simple linear interpolation.
(After those four valuse, B becomes the new A and the next value from the
digital side becomes B...)
More complex filters can be implemented with more A-to-Ds (or a series of
sample/holds or a bucket brigade etc) and more complex maths in the
combinations.
IIR filters can be implemented with a sample and hold that remembers the
last _output_
And so on. (but dion't forget the conventional analogue filter on the
output)
No DSP required.
Fun,eh?
I have the following available, both from HP:

Hi gang. Well, my father is safely transitioned to his iMac, so as soon as I
get done sorting stuff out, I'll have an apple2GS with 4 megs of ram and a
printer card, along with a monitor, 2 3.5 inch drives, and a 5.25 inch drive to
sell. In a related note, I got my 2e running with a hard disk. It boots
to Prodos so fast it doesn't bear mentioning... but it's been a long time since
I used an 8 bit apple2, how do you transition from one .SYS image to another?
I have a launcher that does the job on my GS in 2e mode, but my e doesn't appear
to have enough ram to run it.

Then I would say that it may depend on what you specified for the
output files for the sysgen.
You see, it is possible for just about any command issued under RT
to specify a disk without a filename... in which case the output of
whatever command you have issued will be to the *disk*, beginning
with block 0... this means that depending on how many blocks are
written, you may wipe out the boot block (0), home block (1),
secondary boot blocks (2-5), directory (6-67) and files (beginning
with block 68).

Hmmm... then sysgen and what it was doing may not be the problem. What
is the disk you are using? If an MSCP disk (like an RD series disk),
one or more blocks may have the 'forced error' bit set... which results
in errors when you attempt to read it. The way to clear this error is
to write the block (which I believe results in a revectoring process for
the bad block). The data for that block may be lost, however...
I seem to remember the option '/K' for DUP... I'll have to check the
documentation.
One thing which may be a problem is that if the bad block is in the
'system area', blocks 0-68, then RT pretty much refuses to allow you
to do anything with the disk... the idea being that there are times
when not enough of a device driver is in memory to do bad-block
revectoring...

Well, and of course there's Minix (where Linux started)...
Any Unix clones for 8080/Z80 systems? It ought to be doable, given that the
original Unix was done on a 64KB address space machine...

Displaywriter system generally consisted of the following boxes:
System unit. PC-sized, half the case == power supply, other half == card
cage. Card cage contains system board with 8088 and other cards.
Keyboard. The thing you've got
Monitor. Very similar to IBM original (mono) PC monitor, I think
Printer. Daisywheel, EBCDIC, current loop.
Disk drives. Usually a dual 8" unit. Could be SSSD or DSDD iirc.

Hi Kevan. I hope you do not kill your archive.It is a thankless task and you
deserve kudos for undertaking it. I for one appreciate your efforts greatly,
and the alternative would result in increased mail as questions answered in
earlier threads were reposted. I also would have to get a bigger hard drive for
keepable posts which are numerous on this list. I don't think I have
ever received spam related to this mail-list. I did get some mined from the
CoCo list and classicmac list I believe but I unsubscribed to those a whle ago
for other reasons. Spam is a fact of life for anyone using the net. I use an
altered address for newsgroups however, which cut down considerably on the
spam I was receiving, but I still get some via other activities. I suspect even
Yahoo or Delphi lists etc., are not secure. Surely those who object to
archiving could use an altered address. Aren't there also means such as deja
news' "no archive" to achieve this ?

Hi there.
I finally scored a piece of disk-based software for Atari 8-bits, so I
decided today to test out my atari disk drives to see if any of them
actually worked.
One 1050 did.
The other 1050 doesn't run the seek test when you turn it on, and is
invisible to the computer. I removed the actual disk drive from the
cabinet and verified that it does in fact work in the other 1050 chassis.
While doing this I noticed that the non-working 1050 seemed to have had a
modification done (rather sloppily, I might add; I suspect this has
something to do with why it doesn't work properly).
There is a hand-written silver sticker over what I'm assuming is an EPROM
that reads, "Doubler". There is a second Motorola 6810 piggybacked onto
the normal 6810, and a couple of jumper wires leading off into the PCB.
What was this, and how was it done properly (so I can verify that it's
ok)?
I have a Percom branded full height disk with Atari SIO connects on that
also seems to not work. I think this is because I need to decipher the
4-position DIP switch at the back panel. Any hints? As it is now, the
access light repeatedly switches on and goes off again, each accompanied
by a moderately loud click. The light is on for a second and then off for
maybe two. It doesn't ever stop doing this, and the drive is invisble to
the computer. The drive inside is full height, and made by Tandon I
believe.
ok

Yeah, there's been a rash of disappearences, some have reported suspicious

Why yes, now that I look it is. Kudo's to you BTW - it's a very nice clean
mod. I will do it if I have to, but wanted to check around for the "real
thing". There's just something heartsinking about taking a dremmel tool to
the front of my PC05 :)
One question though - why is the switch needed anyway (I never used the real
thing before)? It would seem to me that the PC05 arrangement where power is
turned on when data is sent works fine - why put a switch on it? If the
switch isn't needed for easy access, it could always be put on the rear or
out of site.

Yup - the previous owner didn't have that either. I'm still hunting for the
module, but quite determined.

True. I'll keep looking for a bit still... THANKS!
PS - I hope you didn't mind but someone on the list asked me for a copy of
the PC05/4 mod, so I passed on your email address. I apologize in advance if
youd've preferred me not to.

What was the last thing you did (exact command, if you can remember it)
before you noticed the disk directory was bad - this will help in
determining how bad off you are.
If it was something trivial, and the directory (blocks 6 to 68) is
intact, it probably is something wrong with the home block (block 1).
If it wasn't something trivial, then the files may still be there, but
it will take some work finding the beginning of them (and it will
take your knowledge of what was on the disk).
Remember, RT-11 files are contiguous -- once you've found the beginning
of one, the whole file will be there (unless it was partially
overwritten).

As I mentioned, it depends on what you might have done... then again, the
controller might have, in a fit of brilliance, written whatever it pleased
on the disk...

The headquarters and factory were in the Sorrento Valley, although their
mailing address may have been San Diego. I visited their offices once. I
supported a DSC Meta-4 for several years, about 1973 to 1976. It replaced
an IBM 1130 which it emulated exactly, but was 10 times faster when running
IBM 1130 FORTRAN IV programs. It was an elegantly simple machine. The
micro controller was truly a RISC machine, I think it had a 3 bit op code, 8
instructions.
>>Valley area) around 1970. IIRC it was called an 1130 clone, but

Yes it had the set/clear memory protection bits. The memory arrays in IBM
1130/1800's were 18 bits ... 16 data bits and 2 parity bits for an 1130 and
16 bits, one parity bit and one memory protect bit for the 1800.

The 1130/1800 addressed 32K words, but the DSC Meta-4 had a feature so that
you could load 64K or RAM, then context switch between two 32K banks. In
this manner they developed a multi user 1130 timesharing system. The
timesharing control system was in the upper 32K and it swapped out 1130
users. If you had a fixed head disk attached, a feature available only on
the DSC Meta-4, not the 1130, you could swap out the whole 32K in some
ridiculously short time, like 50 ms., then swap in another 32K user in 50
ms. and pick up where they left off. It really worked, we attached 8 dumb
terminals to it and had 8 simultaneous 1130's running for less than the
price of a single IBM 1130, and since it was 10 times faster than an 1130,
each user could be running at about the same speed as an 1130, if they were
compute bound ... not usually because most of the users were pounding the
keyboard editing FORTRAN code and compiling. It worked well until we
replaced it with a DEC SYSTEM-20 which was 10 to 100 times faster still ...
at about the same price.
I still have the manuals for the Meta-4, even though I was dumb enough to
get rid of all of my 1130 manuals.
As an aside, DSC developed the line of National Semiconductor IBM Mainframe
clones that are now one of the Japanese lines ... and disappeared.

Thanks, Hans, for pointing this out. None of my web searches had found

Does anyone know of any other IBM 1130's in North America? I'd go a fair
