That looks like a compressed .ASM source file. All you
should need to do is to uncompress the file.

I don't know if this has been answered or not, but at
the sake of being redundant I'll throw in my two
cents.
Kodak had a line of CDs called "InfoGuard", which have
a gold colored reflective surface. The ones I have
are for data (computers).
They are reputed to be indestructible compared to
cheapie media. The protective layer on them is so
strong/thick/opaque (choose the correct one) that my
Yamaha 4416S can't write them reliably over 2x speed.
The Yamaha wasn't a cheapie, so I contacted both
Yamaha and Kodak tech support. They knew of the
problem, and advised be to write at 2x even though the
drive and media are rated for 4x.
The discs I've written at 2x are readable. I treat my
discs well, so I can't tell you if they really are indestructible.

Yes, this is the case. I would guess that the LSI multiplexes the
digits without any other drivers. The DOW labels are probably treated as
segments of a 7th digit by the LSI

That makes sense, given how that style of case goes.

I've never tried to hack right to a VFD. I've only ever played with
ones that have controllers.

That's more or less what I'm leaning towards. I have a Matrix Orbital 20x4
VFD from Linux Central that is currently mounted behind a disk drive bay
bracket. It is easily movable.

Can we define "junk" for the purposes
of this discussion?
Is it junk because:
(a) you make more coasters than you would
believe is reasonable
(b) you find a higher failure rate when trying
to read them two years later than you
think is reasonable
(c) you don't believe that it will last the
twenty years (or whatever they claim)
?
Given a CD-R (blank or already written),
what tool(s) do you use to determine the
characteristics on which you are
judging it and what are "good" and
"bad" things to look out for?
Personally, I have only had one read-failure
in several hundred burns. That's not counting
a few coasters along the way - this was a
partial read-failure some six months to
a year later when I came to use the CD.
I have no idea whether the data was ever written
correctly (since EasyCD Creator - which
came with the drive - does not seem to have
a read-after-write check). Since then
I have performed a comparison-against-source
step after burning any CD. Fingers crossed, no
further failures so far.

Hi:
I have one of these clocks, but haven't opened it in a while. I
believe that it's an extruded Al case that would prevent you from expanding
the case vertically. If it weren't for the display, the PCB could fit in the
Hayes 300 case.
As I recall, there's a single 40-pin LSI chip with some support
chips and various passives. IIRC, the LSI is a General Instruments chip.
There's also a 2xAA battery backup.
As far as the display, it looks to be a Futaba clock display.
Problem is is that no one carries them. Jameco has one, but it's only
4-digits.
If I were retrofitting/rebuilding the clock, and $$$ wasn't an
issue, I'd use a Noritake serial VFD display with a custom font and a PIC
for the clock.

I noticed from the picture from the cover of the manual that it is the same
style as a 1200-baud modem, but taller (to accomodate the display). It
looks about the same size as my Tecmar T-Disk case. I'd have to go look,
but it depends on which style of extruded aluminum case they used if it
could be expanded vertically. The width would be fixed by the size of the
top and bottom plates, but it might be possible to fit side risers.
In any case, I'm not sure where I'd get a compatible display. I also play
with LCD (and VFD) displays with the LCDproc project
(lcdproc.omnipotent.net)
I have one 20x4 VFD and a couple 20x2 displays (so-called "Pole Displays"
for cash registers - RS-232 and 6VAC to drive them). It wouldn't look like
a Chronograph, but I could fit an IR emitter to the top of the Pole Display
(under a red lens) and set up receivers to pick up the time that way. I
presume if I used a carrier other than the one used by IrDA, I could still
use the link between my laptop and desktop. I suppose I would have to write
a PalmOS app to read the time.
This would be easy to prototype with a Pole display and a Linux box
with a few serial ports. I could at least do a proof-of-concept
prototype. I've also thought about turning an iOpener into a wall clock.
Then there is this wall-mount 486 I have with a 10" screen, two PCMCIA
slots, an ISA slot, internal HD, etc. I was just contemplating getting
a set of Diamond HomeFree cards (cheap) but didn't know if there were
Linux drivers for it or not.
> ...or maybe you can turn the status lights into a binary clock output?
I'm an old hand with Binary Clocks (I've built several and even have
an interrupt driven software one for the PET that fits in the cassette
buffer and "draws" the clock face in the upper-left corner of the screen
that I wrote when I was 13 ;-) I'm even looking at one now on top of
my monitor at work (you should hear some of the comments I get).
So... while it's a nice idea in theory, unless you rotated the time through
a modem faceplate digit by digit, I don't see how you could fit it into
the case for a 1200-baud modem.

It would be all of that. Now if only I could get some time off when one
of the VCFs is running. :-(
Lots of ideas, plenty of ways to roll it. No time.

FWIW it aired on Sunday (IIRC)
in the UK on Channel 4 (IIRC).
I missed the beginning but I did get to
see the Altair, the Apple, the IBM PC,
Cap'n Crunch, Woz and Mitnik.
I assumed that I'd missed the
point because I missed the start
but now I realise that I was not
supposed to actually learn
anything.
("Space" on BBC1 was a bit of a
disappointment too)

That's what I am trying to clarify.
I'd rather not wait the ten or twenty years.
I've already learnt my lesson ... all my floppies
will eventually make it onto CD in some image
format or other. Within ten years I expect all my CDs
(and DVDs) to have made it onto C3D.
I don't yet know where I'll be headed twenty
years after that :-)

Not sure, but I think the real thing has an early PIC inside.
If Eric Smith's reading maybe he can tell us, I think I got this
bit by being present when he opened one up to see what made it
tick (ha ha).

That makes sense, as a few of the IIIs that I took had no floppies. Also, I
found a couple of disks last night (not original) that were labeled "Network
Scripsit". There were also directions on how to start the host computer,
then start up the slaves...
