After just a couple days of using this thing it "flies" alright! Stupid fast! It is 1 heavy "mofu" though! I ended up getting 1 of those large trays with the padding cushion on the bottom for when I use it when I'm not sat at my desk. I know there's a lot more stuff inside it compared to my last laptop but "gee whizz"!
Happy with it so far but i'll let you know if I find anything that bugs me other that it's fat azz! 

Yeah, they're a beast of a machine in weight. We were seeing around 3.2 GB/S from the SSD, be interesting to see how yours compares as I think it's slightly newer...

Cool, how would i find that out? I can work and use these things for general day to day things but i'm no "whizz kid" LOL

In fact mine may not be quicker as I don't have the high spec machine. I think mine is quite lower end compared to some of the others. I didn't go for the topped out model.

You can use a freeware benchmarker such as AS SSD Benchmark to find out how the drive performs: https://www.techspot.com/downloads/6014-as-ssd-benchmark.html (there are also many other progs like this)

Today AliExpress sent me a small pile of wrong parts. (After about 300 orders I'm pretty happy.)

I have asked for the correct parts but I have no idea what these are. They look kind'a cool. They are marked:

SI
6K
4X

The "6K" is molded onto a circle in the center which might or might not be a window.

Any ideas?  Thanks.

[Alex Eisenhut]

Don't know why either. It's pretty cool though.

Some sort of optocoupler or photosensor?  Have you tried doing diode or resistance checks with a DMM across the various lead combinations?

Because it IS cool. Any interesting ROMs in the rear port? Mine came from Las Vegas and had a program ROM inside to program the slot machines

Today I bought these (2x TEA1611T) to fix my Panasonic Viera that doesn't want to switch on anymore.

I downloaded that program and it reports that my Crucial 512Gb is a 1Tb so I'm wondering just how accurate that program really is if it gets the starting information wrong to start off with?

[McBryce]

Oooo, that's not good. Maybe try one of the other programs. I definitely wouldn't let that one write to my drive when it can't even tell what size it is.

Does it have full RAM ? I still have a spare RAM chip for the 200 should be also for this one I guess.

[McBryce]

Can't remember if the RAMs are like the ROMs, but the ROMs are definitely strange, with folded back pins with a strange outer plastic frame.

Arrived in the post yesterday, this fine Data Precision 3500 multimeter! It has a 5½ digit Panaplex display. Seems to work OK. There's an edge connector on the back to connect to a the DMM's internal signals, allowing for external control and readout. Date codes show that is was built in 1974 or so.

[Specmaster]

Very nice, I was tempted by that as well, but I already have 5 5.5 digit meters so I thought enough is enough 
I like the display on it.

Agree 100%! I got a Tandy 102 plus several other goodies a few weeks ago. No ROM programs, though (only cassetes).

Interesting; I haven't opened my 102 yet, but this looks quite similar to the RAM modules of my original TRS 80 Model 100.

My 102 seems to be fully equipped with RAM (it says 29xxx Bytes free), but the original Model 100 has only three out of four memory slots.

I have the 17” nvidia 1070, 7700hq CPU, 1tb ssd, 16gb ram, 4K gsync display with the big battery. Really nice for working anywhere even though it’s about two years old now. If you didn’t get both HD filled but it was an option you can buy the cable and bracket and install another yourself. It is pretty handy having a few TB HD space sometimes. Also if it goes on sale soon you can usually get them to give you the difference too. Nice laptops though and they seem to hold up well over time.

These were indeed more for the Model200 which could hold 72kRAM, I believe it used bankswitching.
I gave mine away 8 years ago, sometimes I still regret that, it was a very nice piece of hardware.

The Model 100 and the Tandy 102 go up to 32kB and the 8080 has 16 address lines - certainly some memory bank switching would be needed to get the full 72kB.

Searched the store products and found it. They are IS471F, "OPIC Light Detector with Built-in Signal Processing Circuit for Light Modulation System" for demodulating IR signals.

Turns out it's the tiny dot on the flat face that is the aperature.

Haven't received it yet. It is "as is, for parts", no goodies shown in the eBay pictures. It's mostly because I'll finally get to take one apart myself, and hopefully fix it. Dave already took one apart.

Good luck. My 102 has been working flawlessly, but my Model 100 (I got a few years ago) has a very intermittent issue where, from time to time, it refuses to turn on for many retries, only to magically turn on again with absolutely no apparent reason. Any memory contents are completely wiped when this happens.

I have tried many things to make it reliable again, to no avail. I need to bring it back to my desk and try different approaches.
