A lot of documentation about the ULA for the ZX81 and ZX Spectrum has been bought from ebay.
There is a link to the files in the video description.

I dunno they were flexible with the Piranha art work displaying it in the guildhall temporarily.

There are additional traffic lights on the blackwall tunnel further in and a slip road out that can be used for overheight vehicles. I do remember having a 10-15 minute wait once while they sorted things out when a lorry driver got caught.
I'd have a feeling there are automated signs prior to the tunnel (or at least used to be) but I've not been through the tunnel for a year or so and things will have changed with the Silvertown tunnel opening.
I have seen someone not paying attention at the Rotherhithe tunnel and the roof of their van was a mess (and they're going to pick up a fine probably due to restrictions, the 2 tonnes gross weight limit is lower than a lot of van drivers expect)
Edit there were: https://maps.app.goo.gl/MP7fkhS394DJPQaZ9 If you zoom in you can see the overheight vehicle warning.

Copper was already on the bottom of the ships by then to stop ship worm (terodo Navalis), it also had the advantage of stopping weed growth.
A quick browse through Wikipedia suggests that entire Royal Navy had copper by the late 1790s.

As far as I'm aware they do need an act of parliment to close it down. The one to create the market on the current site is an Act of Parliament (The Metropolitan Meat and Poultry Market Act of 1860) which should protect the site from becoming anything but a place to provide Meat & Poultry

DOS 3.3 was mostly Shepardson Microsystems Paul Laughton and Randy Wigginton from Apple. Woz supplied the RWTS routines for reading / writing sectors.

There is a detailed description of the circuit with the PAL colour card (it's on the euro //e motherboard) in Understanding the Apple //e by Sather (see archive.org for a copy) on pages 8-16 -> 8-19.
You do get the green/purple fringes on text, the euro //e has a switch on the motherboard that turns off the TCA650 and forces mono mode which is handy for 80 column work.
I _suspect_ you don't get all of the NTSC artifacts since PAL will be a bit better, but I really need to get my TV plugged in on my //e running one of the games (adventures typically) that use artifiacts to check.
The other alternative is the apple authorised ITT2020 which added an extra bit to the display so shows "jail bars" on screen when running ][ software. Again I should drag mine out to do some testing.

It's a different model. Microsoft did work on green threads a while ago and decided against continuing.

The time to send over a 1Gbps network looks very wrong. Each bit takes 1ns (by definition) so sending 1K byte must take at least 8192ns
In past lives I've written embedded software, network protocols, accounting software, designed Ethernet chips, designed and built 68000 and 80286 hardware for embedded use.
Currently writing C# in the city of London.
Can write JavaScript but it's not really my thing...
