Have you observed the movement of the drive belt to ensure that it is working correctly? Sometimes replacing the belt isn't always the final answer to belt issues.

Just my 2 cents, but one thing about the organization of things I've always found confusing is the specific company forums (Tandy/Radio Shack, etc...) vs. Handhelds/Portables. If one has a Tandy laptop, where is the better place to post, the company forum, or the general portables forum? It...

I can't imagine that ever being true...

Oh, that is strange. I've never seen one like that. You can repair them with some effort. If you want some info on repair them, I can look up the info. If I remember it takes a few unusual tools.

Yep, you can tell if it is a C2 or the slightly revised C1LA if the touchpad area is one piece and is completely capacitive. If it seems more like 3 distinct area with the middle piece being capacitive and the two areas next to it being resistive, it's the first revision C2. Someone has made...

Do you know which model and revision it is?

Good update. Given the dimensions of the 1660 and 1680, I thought they wouldn't fit. My mistake.

Success. I was able to boot a 3800HD from the GoTek floppy emulator running FlashFloppy using a generic 34 pin to 26 conductor FFC/FPC adapter, a secondary adapter board, one FFC cable, and one FPC cable. As a result of the way the floppy interface is oriented in the Tandy laptops one needs to...

I have been able to determine the "pinout" of the 26 connector interface for the Matsushita EME-26x series of floppy drives, which is also the corresponding pinout for the 1800HD, 2810HD, 2820HD, 3800HD, 3810HD, 3820HD floppy interface. It is the following: 1 +5 Vdc 14 Step 2...

What's the best way to clean 5 1/4" external disk drive heads without taking the drive apart? I would get a "cleaning kit" but $40-50 is just absurd. Is there a way to make a homemade 5 1/4" "cleaning" disk using the housing of a typical 5 1/4" disk and replacing the internal disk media with...

RAM chips from that era are known to go bad due to the limited quality of the manufacturing technology at that time. You might need to test the chips in order to ensure they are all good (and you might as well socket them at the same time).

To follow up on this, the 34 pin to 26 conductor FFC adapters have the 26 pin interface upside down compared to the Matsushita (Panasonic) drives in the Tandy laptops, as a result the pinout is reversed. As such, you need to use a "reverse" FFC cable to interface between the adapter and the...

I thought I'd share some information on various GRiD bags so other people could make sure if they come across one they will know if it fits their system. This is one of them: This type of bag will perfectly fit a GRiD 1720, 1750, 1755, or 1755 486/SLC and possibly the 1810 but none of the...

Well, I ordered one, so I'll report back with my experience once it gets here.

I thought with the "Best Offer" button maybe he was open to reasonable offers and was just putting stuff up with high prices just to see what people would offer. Unfortunately I may be wrong about that.

Not my store, I am not affiliated with the store in any way, I have no idea who the person is that runs the store nor whose stuff they are selling. I thought I'd mention it here since it seems like some of the stuff is unusual enough to warrant a mention. Also, if anyone buys anything, and...

Nope, help yourself. The more places it exists, the better the chance it will persist into the future for other GRiD users.

Does anyone know if the 26 connector FPC floppy drive ribbon cable pinout for the Tandy 1500HD/2810/3810HD laptops is known? Or if it is a common standard? I've come across a number of 34-pin + floppy power connector to 26 connector FPC floppy drive cable adapters and want to find out if that...

Okay, I resorted and organized all the files so it should be much easier to find things. Any questions or concerns, let me know. As always, feel free to copy, rehost, archive, etc... anything in there. None of it is mine, I just asked to keep a copy of it online so it wouldn't get lost to time.

Looking over the CMOS utility for the 1755, it makes me think there really wasn't a 1755 486SLC-25, or possibly they planned to do a single final run with that processor but it never happened. All the known versions of the 1755 CMOS Utility have an entry for selecting CPU speed and the only...
