Jamie,

 

Just wanted to check and see if you were successful in getting some new zebra 
strips made.

Subject: [M100] New zebra strips for M100 display — any interest?

 

Hey All,

I do consumer product R as my day job.  I’ve admired the M100 as a brilliant 
product for the past decade or so, and just picked up a really sad example that 
I’m trying to resuscitate.

A couple of weeks ago I had a some fine-pitch prototype zebra strips made up to 
fit the M100 LCD (see pic).  The first prototypes are about 0.3mm too tall.  
I’ll likely have another set of prototypes run with an adjusted height.

I have two questions:

Is there enough interest here on the list to justify an order of 1000 pieces or 
so?  (Likely price is a few dollars each strip — more to come on price.)

Do any of you have dead LCDs that you would be wiling to sacrifice to the 
testing gods?  I would like to see ten or so LCDs improved by an upgrade to the 
new strips before placing a bigger order.

Hey guys,

New (final?!) zebra strip prototypes have arrived.  I should have time to 
assemble displays around them in the next week.

More to come. . .

Hey guys,

Quick update.  I have four displays on hand (thanks Josh!).  Measurements 
suggest a zebra strip height between 3.3mm and 3.4 mm will work best.   I’ve

Re: [M100] New zebra strips for M100 display ? any interest?

[Jamie Nichol]

Stephen,

I/we would have to test with other displays to know how broadly these might 
apply.   For now, the M100 is the first target.

If you have displays for other machines and are willing to take measurements or 
send dead examples, that would be super helpful.

Take care,

[Kevin Becker]

I have one M100 that could potentially use new zebra strips.  I’d be down for 4 
pairs as well just to have some on hand and help chip away at the order.

Re: [M100] New zebra strips for M100 display ? any interest?

[Stephen Adolph]

you can count me in for some quantity.  Are these strips usable for T102
and M100?  Assume 8201, M10, 8300, KC85 also.
What about T200?

I will also pick some up to have on hand, just in case. If I can help test let 
me know.

Hey All,

I do consumer product R as my day job.??I?ve admired the M100 as a brilliant 
product for the past decade or so, and just picked up a really sad example that 
I?m trying to resuscitate.

A couple of weeks ago I had a some fine-pitch prototype zebra strips made up to

tall.??I?ll likely have another set of prototypes run with an adjusted height.

I have two questions:

Is there enough interest here on the list to justify an order of 1000 pieces or 
so???(Likely price is a few dollars each strip ? more to come on price.)

Do any of you have dead LCDs that you would be wiling to sacrifice to the 
testing gods???I would like to see ten or so LCDs improved by an upgrade to the 
new strips before placing a bigger order.

Re: [M100] New zebra strips for M100 display ? any interest?

[Jamie Nichol]

Peter,

Looks like a pair of new zebra strips will cost $6 with usps shipping to 
contiguous USA.

Manufacturer is fujipoly.  Better quality supplier.

I’d love to sign you up for a dozen, once testing looks good.

Anyone else interested at this price?

I would absolutely buy a small stock of new zebras for the M100! I've
been contemplating such a project myself for years. Over the last 30
years, the zebras have deformed to where they seem to take permanent
deformation from the copper tracks on the PCB and I've never been able
to get them back together again after cleaning. Having new parts
available would be terrific.

Let me see how many problematic LCDs I have in my "parts machines"
right now and I'll get back to you.

Re: [M100] New zebra strips for M100 display — any interest?

[Jeffrey Birt]

That is quite the initiative. I’m not sure how many LCD problems are related to 
zebra strips. Of the ones I have had with problem with or helped diagnose

 

a.  Corroded contact pad and bad LCD glass, one row was bad, you can turn 
glass 180 to verify.
b.  Bad driver chip

 

Not a big sample size. No doubt some others are zebra strip related. I have 
only heard a few rumblings about zebra strips on the various forums and such 
too. If I were to try swapping an M100 LCD glass into a T102 for example I 
might go ahead and install new zebra strips to be safe, so I don’t have to pull 
it back apart multiple times to mess with the original one. 

It might take 3-5 years to find enough folks who need to be zebra strips for 
M100s to go through 1,000 which is something to consider when you are tying up 
your money upfront to purchase them. I have commissioned a few reproduction 
parts for old computers now and just want to pass along what I have learned.

Hey All,

I do consumer product R as my day job.  I’ve admired the M100 as a brilliant 
product for the past decade or so, and just picked up a really sad example that 
I’m trying to resuscitate.

A couple of weeks ago I had a some fine-pitch prototype zebra strips made up to 
fit the M100 LCD (see pic).  The first prototypes are about 0.3mm too tall.  
I’ll likely have another set of prototypes run with an adjusted height.

I have two questions:

Is there enough interest here on the list to justify an order of 1000 pieces or 
so?  (Likely price is a few dollars each strip — more to come on price.)

Do any of you have dead LCDs that you would be wiling to sacrifice to the 
testing gods?  I would like to see ten or so LCDs improved by an upgrade to the 
new strips before placing a bigger order.

On one the M100s I repaired earlier this year, it was not so much the zebra 
strips, but that they seemed to have shrunk. I had to apply thick tape inside 
of the metal LCD frame  to increase the pressure on the strip. I think new 
zebra strips of the correct height would save quite a few M100s. I am 
interested in buying 4 of them.

I do not think it will help with missing horizontal lines. I am pretty sure 
that would be broken traces or lifted pins on an IC. I only have experience 
with the one that I repaired, so take that with a grain of salt.

Steve,

Thanks for sharing your experience.  Depends on the display, I guess?

New zebra strips were the answer for the display I have on hand — worked better 
than adding tape between the glass and bezel.

For me it has usually been a pcb problem.
