Been to the UK first time after Brexit, and it was easier than I expected – especially with the special gear I carried with me, you’ll see on the photos underneath 😉 !
Reason for this visit was Spectrum40 at Walsall, on Saturday 30 April 2022.
So, Friday morning, up we go, and… down again, after only short of an hour.
Jumped in and out Stansted Airports WH Smith, for this warm welcome I got:
Nothing serious with luggage and ID checks, so off we go with the train to London, then a subway just to get to another train to Birmingham:
Once I finally were done with public transport after over 3 hours, I got out of the train station at Walsall.
Bigger WH Smith here, and yes! All ur ZX Spectrum and retro computer mag – great work Chris Wilkins!
So, took a walk to my hotel, about 3 miles from the train station.
Then did some work on the special thingy I brought with me, to make it… shine! 😉
After an hour or two, got to a pub to meet up with some great guys.
After that we had dinner at the other side of the street (which is a good thing after some beers..).
I made one mistake after that: I walked back to the hotel, though my feet already started aching because I brought the wrong shoes, and had quite a heavy backpack with me.
Anyway, next day, of we go to the venue!
Yes, walked again, bad stuff…
Decided on my way over, to install Uber when I got there.
Steve White talking about Ant Attack and more!
Some of the photos I made with insanely awesome people:
Chris Wilkins, who has some great ideas for hands-on retro events!
Peter Smith with his stall:
Brendan Alford, master genius coder!
I also made photos with Andrew Owen, Mark Smith, and many others, but for some reason I can’t find them on my phone!
Had a great long talk with Andrew about the Chloe computer which we’re going to actually bring to the market.
Talked with Mark about loads of things, and the cherry on the pie: I’VE SEEN IT, TOUCHED IT, MY LIFE IS COMPLETE NOW!

Pfew, that’s heavy stuff… Back on my feet…
Wayne good mate!
And Jason Railton, who made himself famous in one day, with this insane setup:
*ONE* ZX Spectrum, FOUR players, and…. TWO monitors!
I’ll get into this more this year, with interviews with Jason, Mark Smith, Brendan Alford, and many more!
Jessie really liked my portable backpack ZX Spectrum 40 with programmable ARGB keyboard!
She explained to me how Choas worked, which I really enjoyed!!
Unfortunately the battery died just after making this photo – I’m so sorry Jessie!
The battery, a simple Mi 10.000mAh powerbank, did hold up quite some time, about 6 hours!
Tim Gilberts made this photo of me. Well… more or less of me:
I did a ‘let’s do a short 3 minute live stream’-live stream of about 50 minutes:
I was exhausted after this day…
So I did install Uber, and got my first ever Uber ride! The guy didn’t say much..
Next morning I got up as early as I could, to be able to visit London to do some distanted photo challenge with my kids.
Here are some shots – I think I did everything they dictated me, but these are just a couple of them:
I’m bigger than the Ben:
After a really lightning fast visit to London, I got to the airport, to.. relax 😉
So I got myself some coffee.
Then back up and… ‘immediately’ down again.
One of the souvenirs I took back with me:
Yeah so, subway, train, plane, venue, really don’t know where or when I picked it up…
Anyway, I’ll live.
This was great!
See you all in November!

Page about the TVM802A pick and place machine
I just created this page, dedicated to the TVM802A machine (a lot applies to the TVM802B as well).
I answer questions that I’m asked from time to time.
USING A AM29F040(B) FLASH ROM ON A HARLEQUIN 128K REV 2D
Just created this page explaining how to use this chip:
Dear ZX Spectrum enthusiast,
To be able to finally process all open orders, repairs and other custom requests, I made the decision yesterday to put stock levels to 0 – stock levels will raise when new products are completely ready and on the shelves.
I’ve promised too many times to process all remaining repairs and other orders, but so far I haven’t been able to keep that promise – I am very sorry for that!
This, and another big reason for this change, is explained in this video: https://www.youtube.com/watch?v=OKUEor_KwXI

AY-3-891x or YM2149 detection utility for ZX Spectrum
We recently discovered that many AY-3-8910 soundchips that currently can be obtained, are actually YM2149 soundchips, but ‘blacktopped’ and ‘remarked’ as AY-3-8910, most probably because of a demand for the AY-3-8910.
YM2149’s are indeed pincompatible and do work just fine instead of a AY-3-8910, but sound a little different (check out this video).
If you want to check that the soundchip on e.g. your sound system is an ‘original’* AY-3-891x (-8910 / -8912 / -8913) or remarked YM2149 chip, you can use this free detection tool: https://velesoft.speccy.cz/other/aydete.zip
Big thanks to George Velesoft for this tool, and Peter Smith for the testing.
* The currently obtainable chips, mostly from China, are often blacktopped and remarked, but under the new layers of paint it might still or may not be be an original chip.
So IT CAN STILL BE SOME CLONE! We can’t tell for sure for all the chips on the market.
This applies to:
- ZX Spectrum 128K models with integrated AY-3-8912
- Harlequin / Nuvo / Omni with either AY-3-8912 or AY-3-8910 (later models) or ‘File’-brand clone
- ZX-AY or other external sound add-on with e.g. AY-3-8912 or AY-3-8910
Some more background info based on our experience and the people we discussed this with:
- AY-3-8912’s often seem to be legit, and working (we had about 2% defective ones, for which we claim a refund since these chips now cost about €7 each).
- AY-3-8913’s seem to be fake or semi-defective since the noise generator doesn’t work with *ALL* that we tested, but these might also be some other sound chip that is pin compatible but not sound-equal, costing about €1 only.
- AY-3-8910’s seem to be remarked YM2149’s mostly: pincompatible, fully working, but sound slightly different. Many people prefer the YM over the AY chips because of improved features, costing about €1 only.
