I'm interested in the old line numbered basics. Are there any web sites or email
lists regarding programming in the old basic languages?
Stephanie sring(a)uslink.net
The Comprehensive Computer Catalogue at
http://plato.digiweb.com/~hansp/ccc/ccorgs.htm
lists this computer as follows:
----------------------------------------------------------------------------
-----------
"The ECD Corp's MicroMind was a 6502-based computer dating to around the
time of the Apple II. It had memory management (!) and an advanced video
display with downloadable fonts, up to 132 characters per line, and smooth
scrolling.
The prototypes were wire-wrapped, as were the initial (and only, alas)
models that were actually sold. Its smooth-scrolling capability, unique
among micros at the time, made it attractive to hospitals to present the
list of TV stations avilable on hospital channels. The cost of $8K was no
object.
The plan was to go to printed-circuit board, and ads were taken out in Byte
magazine offering the machine for $1500. Orders poured in, but the PC
version never appeared (the orders were all refunded). The 3 founders of ECD
laid off all its employees and held on for awhile, but ECD itself eventually
went bankrupt."
----------------------------------------------------------------------------
------------
I have a number of their ads and was wondering whether anyone has ever seen
one of these machines in person, or knows any one of the developers.

well, any mac II series will need a nubus NIC. If most of the NICs have the
bnc (coax) connector, you'll have to get the same for the mac. Good thing is
that coax NICs (10base2) are easier to find since they are older. I was
lucky to find a combo NIC for my IIsi.

Most electronics suppliers should sell them, though you might have to buy
them in tens or hundreds. they're certainly easy to get here. Another
cheap sopurce is often PC shops that assemble PCs; they get interface cards
and hard drives in them, and tend to throw them away.
The silvered ones are static shielded and static dissipative, the black
conductive ones are static dissipative, the pink ones are not very good at
anything (except perhaps keeping the dust off).

It's plumb gone to Hell in a handbasket! :)
Seriously, the newer compilers/interpreters for the old time languages such
as BASIC, FORTRAN, etc. are benefiting from new ideas introduced in the new
generation of languages. This is of course possible not just because of
new thinking but because cheaper memory and cheaper mass storage allows
code to be added which implement those new fangled ideas. Kinda gotten out
of hand nowadays it seems judging from the amount of code bloat found in
some new compilers.
Back in the early days when every single byte of RAM and disk storage
counted, no matter what new idea came along it was hard to implement as it
had to be supported by hardware resources. And those resources were either
not invented yet or way too expensive for the majority of users.

And of course, let's not forget TimeShare BASIC on the HP2000! <grin>
It ran on 2100, 21MX, and 21MXE systems (all HP). That system brought up a
BASIC environment on each terminal (no access to other languages, etc.). No
editor either, to replace a line you just retyped the line using the same
line number.
According to Jeff Moffat's website, there was also a multiuser BASIC
available on the 2100. It appears to be a stripped down precursor to TSB.
Matter of fact, he has an emuator AND the images for the multiuser BASIC
available on his website. IIRC, it's at http://oscar.taurus.com/~jeff/2100

If memory serves, there are two classes of protective wrap which are
SUPPOSED to be used. One, the "primary" packaging layer, is supposed to be
moderately conductive so that it forms a protective layer around the entire
perpiphery of the card, thereby protecting it (the card) from spot chrges
transferred to it by handling. The other, the "secondary" packaging layer,
is intended to provide mechanical protection for the card and its primary
packaging. Common examples of the primary packaging include the black
conductive bags we commonly see used for this purpose. The pink-poly bags
and bubble wrap, etc, are anti-static but not conductive, and are
consequently qualified as "secondary" packaging, as they create no static
charge on their own, but don't do anything to dissipate it. Aluminum foil,
properly applied will qualify as primary packaging, though it's not ideal
due to its fragility. The fact that it will discharge batteries and other
things likely to be found on a board causes other concerns, but, PROPERLY
applied, it will serve as primary ESD-protective packaging.

The best price I have found recently is from Contact East (800) 743-8181.
http://www.contacteast.com The following is per hundred of each size. 6X10
$7.70 10X12 $13.50 12X18 $24.80. These are the sizes I just recently
bought to cover dual, quad and hex width DEC boards. Granted they are only
1.6 mil but I only use them for end user sales. I have talked one of the
scrappers I work with into saving the ones he gets in for everything else.

I have my office full of some of my favorite toys, and a large

Like I said, I stopped at this point, but you'll notice that once you
read pass the two cycles that make up the sync bit, the rest of the
cycles in that byte consist of one large cycle and one small cycle.
If you compare the cycle lengths IN PAIRS then the different in
small and large cycles becomes more pronounced and you can forget
about the 15 samples definition.(One has to be smaller than the other)
I didn't find the header format reference I mentioned, I do know that
the header is read into the cassette buffer and I believe that make it
about 191 or 192 bytes long.
I also know that when the header is loaded into the cassette buffer in
the C64:
$033D - Low byte of start address
$033E - High byte of start address
$033F - Low byte of ending address
$0340 - High byte of ending address
$0341 - Start of the filename
Looking at the printout I sent, it looks to me that the header starts
with 9 to 1 countdown, then the header ID number. I (again) believe that
01 is the ID for a program header and 04 is the ID for a data file
header. Then you have the start address (01 08 = $0801) and the ending
address (23 08 = $0823). Followed by the filename.

Hi, I came across your address while researching Osborne computers.
My mom is moving, and in packing her things, we came across my late father's
Osborne Model OCC1 computer, printer, and original manuals. The unit was
barely used, as my father passed away shortly after purchasing it.
I was wondering if there is any interest out there for this piece of computer
technology history--either via purchase or donation.
Thank you for your time.

Foil is fine[1], because it's conductive, just like black conductive
plastic bags and black conductive foam, only more so, of course. The
drawback is that it tends to get punctured by the protruding leads and is
easily torn. The point of any static dissipative system is to keep
everything at the same potential.
[1] except for anything that has a backup battery on board, or for a few
CMOS real-time-clock chips (most are OK, though).

Assuming the default settings for the system is the desktop, you can get
back simply by pressing the RETURN key on a line by itself (no spaces,
etc).
You can see the system settings by typing *status. You can set them with
*configure. You can see the environment settings (which mostly also apply
to the desktop) with *show. You can set them with *configure. You can
enter BASIC from the command line with *BASIC. And so on... All of these
commands accept abbreviations, eg *sh. for *show. They're not
case-sensitive, by the way.

I probably should have been more specific about the network card I need.
I'm trying to set up a basic peer-to-peer network between my P200, a P70,
the Mac, and a 5170 in the garage. I have cards for the PC's, but I need
one for the Mac. I'm not sure what kind of card I need (first experience
with a network), so I hope the ones I have for the PC's are the correct type
(they have the BNC connector). Is there any way to tell what type they are
by looking at them?

Thanks to everyone who offered advice; something I was thinking
was to use warm water, and some dishwashing liquid. Does that
seem safe?
I used to use something similar when I worked for FLUKE-- we'd
use water with like a mild detergent. But then, these boards
were specifically manufactured to be cleaned this way.
I'll leave the corestacks alone (well, I'll use a soft brush to
remove the dust from the *outside* of the 'sandwich').
Thanks again, guys.

It's in "BASIC Computer Games", and also on one of the RSTS tapes, I think.
It's one of the classic guess-the-location games; the hurkle hides on a X
by X grid, you guess which square, and for each guess, the computer tells
you roughly which direction you'd have to go in to reach it.
Anyone who can't bear to miss it, can see hurkle and other exciting

(Wednesday). The Computer Science Department has a small exhibit of
historical micros, including a PDP11/23 running 7th Edition UNIX, an Apple
][, a PET 2001-8K (calculator keyboard, and the original PET MOONLANDER
program), Sorcerer, BBC Model B (running Elite and REVS), Apple Mac Plus,
Archimedes A310 (serial no.2, running RISC OS, and acting as the tape drive
for the Sorcerer :-)), SGI Indigo R3000. I'd show more of my collection,
but there's not enough room.

I realize this is totally off topic, but I've really no idea where to go
with a PC question. After months of searching I managed to aquire a brand
new Matrox Millenium II PCI 4Mb Video board, and a 4Mb expansion.
Stupid question, which way does the expansion plug in? I've no doc's for
the expansion and the Matrox web site seems to be useless!
For the curious, yes, there is a reason I've been searching for one of
these boards for months. It's about the best board supported by OPENSTEP,
it is also supported by BeOS, Linux, and some flakey little OS or two out
of Washington.

It should be a 9-pin miniDIN, it's a proprietary mouse. The original one
for a machine of that vintage was a badged Logitech OEM mouse, but any
mouse that outputs raw quadrature signals (fours signals for X0,X1, Y0, Y1)
and three buttons (left, middle, right) will do. CPC
(http://www.cpc.co.uk/home.htm) sell Archimedes-compatible mice, as do
several Acorn dealers.

HENSA have some software packages that allow you to use a serial mouse on
the serial port (http://micros.hensa.ac.uk/platforms/riscos.html). You
can't use a PS/2 mouse directly.

Minimum sensible RAM is 4M, but it will hold up to 256MB, in 72-pin fast
page mode SIMMs (it doesn't need parity, but parity SIMMs will work), 70ns
or faster.
The other memory board is dual-ported VRAM for faster video access. Not
essential.
> Does anyone know what processor it has and how fast it is?
Originally, an Arm 610 on a daughter board. A 710 or 810 or StrongARM will
also work. Many people bought upgrades when they came out, so you often
see 610s or 710s for sale for ten quid or less. Or ask on one of the acorn
newsgroups; they're common enough and cheap enough that people often din't
bother to advertise them, and still have them lying around.
There's a fairly good Acorn FAQ which you can get from the usual sources,
and is posted to the Acorn newsgouops (comp.sys.acorn.*) regularly.
You really don't want this machine. I suggest you parcel it up and send it
to me :-)

If what I've got is for a 9" CRT then I should be able to use it with a
PET!

Careful with that grease! Vaseline is likely to make some plastic alloys
soft, as it contains solvents for some of them. The clear grease most often
used in lubricating plastic gears, bushings, etc, is called "lithium grease"
and is available at most wholesale outlets which sell screws, nuts, bolts,
etc. by the box.
I have, by the way, found that a box of 100 of some of the more common
screws found in electronics is a really worthwhile investment and saves
money in the long run. This is especially true of metric sizes. Here in
Denver, it's the rule rather than the exception that hardware and car parts
stores sell both metric nuts and bolts, yet it's unusual to have bolts and
nuts of the same size as marked on the blister pack actually fit. I don't
know why this is, but it's a real pain in the gluteus maximus! I've never
had this result at Fasteners Inc. I guess that's why I'd rather buy the
small stuff by the box there rather than the handful at the hardware store.

I can keep that in mind. I _won't_ be there Friday; I have to earn the
money to buy the toys.
