So, the restoration is complete! :D

Image

The caps are almost all shined. Well, at least this thing has been put to good use!

Image

The lighting around my desk likes to make anything that isn't pure white look beige. :P

Image

A battle scar from its many years in office

Image

It seems that the cable with a right-angled connector has the complaint of being too short. This one is almost too long.

It also looks like the Datapoint logo could come off to reveal the Acer logo beneath it, but I think I'm going to keep it on. Honor the history of this one. :)

The ANSI bigshots:

Love 'em :D

The DC-3014 has Dell AT101 PBT caps on it (and my AT101 has DC-3014 caps on it, naturally)

So I just recently got this Acer KB101A rebrand off eBay; it's one of the last keyboards I've needed to complete my blue Alps most-wanted list. I've got them all, for the most part, now!

Does anyone know how to brighten up the indicator film? Retrobright does NOTHING to it.

So, here's the board as it was in the beginning:

Image

These are from the eBay listing. Thanks to restoring keyboards all week and last week too, I was getting a bit sick of photodocumentation by the end of things, haha.

The top image shows the cleaned plate, brightened case, and lubed stabs. I also tightened and cleaned the cable's coils. They were a wee bit stretched as I received it. It surely didn't help that the seller wrapped the cable around the board when he packed it, haha. Can't fault him though as he was clearly not an enthusiast. I love that this board saw so much use in an office. I love keyboards with a past.

Never seen a KB101A rebrand like this before, aside from XMIT's Alps SKCM White Texas Instruments-branded KB101A.

That one is very interesting in and of its own right.

As for the Datapoint: As you can see, it's not so bad. Retrobrighting still took a day though.

Image

Label on the back. Glad I took a picture of this, because cleaning the board washed off the white pigment of this label and trying to shield it from water only made it worse as the adhesive of the tape really removed it. I should've done what I had done with the Xerox boards at first, and created a non-adhesive bit to go over the label and only leave the adhesion on the plastic. Ahh, NBD.

Image

I really should've taken a picture of the plate. It was disgustingly grimy. Not gritty, just caked on grime; sticky. I used a bunch of elbow grease, and old toothbrush, and 99% isopropanol to clean the plate squeaky.

For a while, the clicks on the blues died. Alarmed, I came to realize that it was the alcohol seeping into the housings and wetting the leaves. A hair drier made quick work of that and they're all just peachy again. Non-clicky blues feel a lot like SKCM Orange.

There was a sunflower seed on the plate, what looked like christmas sparkle glitter (it's what looks like an LED in one of the eBay pictures, shining through the gaps in the keys), and small styrofoam pellets. Not much of any of these, but damn did this board see some fun times.

Image

Can't use it just yet.

Image

This little thing seems to have always been this odd beige color.

Retrobrighting:

Image

Love this thing.

Image

Immersion takes a much longer time, but is safer for caps as they are prone to bleaching and streaking.

UV!

Nice log! :) Yeah sometimes you can really tell a lot from a keyboard, I once deduced that a guy owned a ginger cat and liked wine from the hair and the fruity smell coming from the keyboard, which I verified by contacting him on eBay xD .

Very nice. I hope it brightens up!

Interesting to hear how unclicky blue feels like orange :|

Okay, OP updated with final bits to the restoration. :D

Everything came out well, but the right shift key decided to float up over night and this dried out with intense UV showering it. It was horribly bleached, so I found a surrogate shift. :P

All is well in KB101A land. I really don't know what my thoughts are on this one. I like it, but I don't think its style is 100% something I care for.

Shocking even to me, because it always seemed so from videos and pictures. :P

It is a pleasant typing experience though. The Leading Edge DC-3014 was nice but it had chattering issues over Orihalcon's Soarer's Converter because of its NKRO, I guess.

Either way, I am very happy to have restored this one, and the fact it saw a lot of time in an office really makes me admire this one, even if the aesthetics aren't 100% to my liking on the KB101A.

Doesn't that side profile shot remind you of something alien though? It's weeerid, but cool. :P

Very nice work, these boards are certainly worth the effort.

Thanks seebart, I agree! Better to restore them than to scrap them for their switches!

Sure if it's possible and even worth it. I can understand people who slaughter obscure terminal boards that are in trashy condition for the switches. I like the looks of the Datapoint a little better than the Leading Edge BTW. Both are better looking than my NTC KB-6151 though.

Yep, I pretty much totally agree with you there. I've had to scrap my own NTC 6151N because I bricked the controller by being an idiot and poking its circuitry while it was plugged in (it was my very first Alps board, no less).

Yeah, I used to think the Leading Edge was rather unsightly before I actually owned one. I guess I'm just biased. :P

The KB101A has always struck me as a nice board. There's just something about its look that I can't describe though. It's a little quirky. Still a very nice board.

Nice sharing. I have no idea there were 3 colors of Alps SKCM Blue exit!

It seems that the dye they used either did not hold the test of time or was splotchy to begin with. Blues are some of the least consistent in appearance. These are all from the same batch, actually, but as you've noted, the colors vary a ton.

I also wanted to mention that I fixed a non-responsive key switch on the "S" position by opening the switch up and taking the spring leaf on the contact and bending it back into shape.

The great thing about Alps switches is that the contacts are more or less sealed; I don't believe they suffer from fatigue like bare leaf contacts do (IE Simplified Alps or Cherry MX). Complicated Alps use a leaf that clips onto the contact sandwich and is replaceable itself. I just bent it out a wee bit and fine tuned it until I found a great balance between reliable actuation and original feel.

I had originally bent it out a bit further and this did ensure actuation every time, but it also gave the switch a stiffer feel. A little tweaking got it just right.

The way I tested the contacts to make sure they were still functional was simply pressing the two halves together. They still registered a key press, so I knew they were still good, and that it was just the detachable spring leaf that was the issue.
