Will it Fit? HM7000 21-pin TXS Bluetooth Sound Chip in all my locomotives! 

Exactly. The DOS analogy was wrong

I will be testing some in the Dapol O gauge. However the 26 needs a high power decoder so that rules these out.

@@JenniferEKirk I did wonder. I am keen to try one in my smaller engines in O gauge! Particularly if I use battery power in the garden

Many thanks! I’ve seen so many people online making claims the HM7000 decoders don’t fit most locos, and this proves those claiming this haven’t actually tried.

20% failure rate isn't ideal. What happened with the fried decoder? I bought three and ok so far.

@@modelrailwaynoob The faulty decoder was working fine then next day it just made a high pitch noise coming out of the speaker and no motor control luckily I bought it from Amazon so sent it back and got a replacement next day no issues so far all working fine.

@@stephenbromley2302 Out of interest, was it with a DC controller or DCC when it failed?

@@modelrailwaynoob it was a dcc controller digitrax dcs 210+

@@stephenbromley2302 OK thx

The 8pin versions can be carefully hard wired in as long as there is space.

It is due soon I believe.

Correct. In fact there aren't many at all.

@@JenniferEKirk like the android app 12th of never

@@modelrailwaynoob is it still not out???

@@MistaMatthews As of today, no

I did - It works fine

@@JenniferEKirk Ace thanks - looks like they have really come up trumps this time

I’ve used TTS chips in Bachmann locos. No problems and no need to change CV settings for me

@@modelrailwaynoob thank you

Where are the myths? I haven’t seen them

DOS was a major problem for the average person. There’s a reason computers only start becoming ubiquitous in the late Nineties.

@@GameHammerCG It was never a problem - to average or not. As I said, it is still used to this day and the analogy used regarding DOC in this context was a poor one. GUI-based operating systems were popular in the late 80s - so again that is incorrect. The use as a home machine and utilised in smaller businesses started to become all the more the case with the demise of the popular home micros with the death of Atari and Commodore in those markets and Amstrad just producing rehashed 8-bit Spectrums in nice cases - but again, they went down the route of building PCs and thus increased the PC into more and more markets and uses. You still used alot of DOS even in the last years of the 20th century, and it would be more DirectX that was the change than setting the IRQs and pins on the hardware that made them easier.

@@johnpapworth433 We are going to have to disagree. GUI OSes in the 80’s were incredibly limited. Hell, even Windows 3.11 was limited and I’m absolutely correct that full Windows-only systems from 95 onward heralded easier-to-use computers, with the resulting massive increase in sales. There is a noticeable increase in domestic computer use as a direct result of Windows. Like it or not, average people (not average computer users) got a computer *because* Windows made them easy to understand.

@@GameHammerCG YOu can disagree as much as you want, it doesn't mean you are right. The differences of GUI in the day were the Apple ones, you had GEM and of course you had Amiga Workbench - along with early Windows, OS/2 etc. GEM was very limited because that is all it was, Apple - I don't care about - but was still flexible, but the others Workbench and Windows were front-ends for their CLI, which meant that you still had a lot to do in CLI than just with a GUI. People STILL use DOS and Powershell to this day. Linux GUIs are developed by developers and are cumbersome, but the whole OS is not popular outside of its fanbase - I too use that, and in some cases - well many cases, it is easier to use the CLI than GUI. Home computer use grew from the 80s, some of us were there for that and saw the rise and fall of the Home Computer whilst seeing them being replaced with the IBM PC and Clones. Even Windows 95 still was a front-end for DOS. People used PCs at work, so they bought what they used as they knew how to drive them at work. One of the jobs I did was convert Instructor Led Training for a certain Govt Body from Amiga to PC - because the Amiga, despite being much more proficient at the job and much faster - was converted because it was mandated to use the PC. Windows being a front-end for DOS, that didn't really change until they went to using the Windows 2000 core for both professional and home-based versions of Windows - and if you used that it became truly stable. So, I think you mistake computer buying increasing with the coincidental change in Windows versions and all the other factors that surround it. You also ignore the fact hardware was cheaper and also became easier to implement which made people of a variety of skill levels have the ability to update their PC, that attributed to DirectX to manage hardware configuration which put off a lot of people using a PC. Then of course True 3D with the old Orchid cards. Cost - cheaper to buy IDE or SATA that SCSi-devices. Intel/Cyrix/IBM/AMD et al were cheaper processors to buy than the Power PC ones and of course the motherboards created to one standard rather than bespoke. I am not a hater of Windows, I do like it and have used every version of it including ME (lol) and seen how much more stable and robust it is compared to how using development tools would crash all the time in Windows 95 and 97 - and long for Windows 2000. Windows was there during the increase of PC use, it is not the main factor for PC sales increasing - if it was all about usability, people would have gone the Mac route for that reason alone.

@@johnpapworth433 tl;dr

The 8 pin and 21 pin have fitted for me so far. I tried them weeks ago.

It is due this quarter.
