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

For the UK the Scottish national library has a similar map finder.

Wendell over at level one techs seems to think that AMD cards are more popular in pro applications.

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.

Doh! missed the date.

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

Also https://www.rmcretro.com which is very hands on.

It is missing commandment 0 - Check the RIFA caps, because they make big stink..

Although arguably commandment 2 is the most important.

Interesting mention of Sidekick Plus, there was a complete SDK for it which I don't think ever got released anywhere (I had a copy as I was working for Borland at the time). It allowed multiple documents to be open at the same time.

It ran on top of several things. I remember the company I worked for (Alfa Systems) uploading IPX drivers to Novell for testing over a modem using IPX as a protocol.

Alfa designed Sage Mainlan originally a z8530 + RS485(?) PC card followed by a 10Mbps Ethernet with our own chip design (Enzo) fabbed as an ASIC by Toshiba. We wrote IPX drivers for both versions.

Interestingly we could hang systems with the 3COM cards in our test systems if we ran at full speed and at somepoint we had the full 500 metres of thick ethernet in the office.

The IPX version that came with Netware 3 was rather nice, I seem to recall it had a buffer of segments and these got filled by the different layers of the network stack as needed along with some fancy protocol filtering so your code only saw just the data packets it was interested in.

Might be worth having a look under Settings / System / Notifications and the check boxes at the bottom of the screen which are:

Show me the Windows welcome experience

Offer suggestions on how I can setup my device

Get Tips and suggestions when I use Windows

(I've posted this in the past, but it does seem to help)

As did Microsoft with ASP (your choice was VBScript or JScript for a scripting language)

I thought the PSReadline module had some of that but then it might be a "nearly" compatible experience which can be really jarring when you hit the edge cases.

Hmm as always Raymond Chen explains

There is some code that controls the speed when there is a single alien left it moves faster right to left see the code at 00C2 in http://computerarcheology.com/Arcade/SpaceInvaders/Code.html

But basically one alien moves every video frame.

On my Lexus that doesn't disable keyless entry, just puts the key fob into sleep mode. There is an option somewhere to disable keyless entirely, but when enabled it means you need to hold the key near (I think less than 10mm from meory) to the push button start.

I can say that Toyota Insurance in the UK takes it seriously, they installed an immobilizer (the key fob for which is branded with a Lexus L) for free on my 2020 Lexus RX to combat this issue. I'm probably going to buy a steering wheel lock, more to advertise that the car will be a pain to steal than for any additional protection.

I first heard of the CAN bus hacking late last year (in an owners forum) but it does seem to have become more wide spread this year.

Interesting, any reason for not discussing AAD yet? (oh and great series BTW)

Partially this is because the Joint Academic NETwork (JANET) in the uk used addresses in the form of [email protected] according to wikipedia the JANET NRS had uk as the top level prior to dns adopting ISO codes in 1984 https://en.wikipedia.org/wiki/JANET_NRS

Since I turned those off I don't think I've had the browser preferences get reset (I suspect this means the next update will be very annoying and reset my settings).

I'm sure multiple variants have been implemented, Borland C++ V2.0 from 1991 (version chosen as it's on bitsavers.org) has a bcd type which IIRC uses the 80 bit 8087 packed decimal type but it's been a long time since I looked at this deeply.

The 7950X3D looks interesting, but I think the cache is on one CCD so it might only boost to 5GHz and the other CCD boosts to 5.7 as it doesn't have the cache.

Going to need to wait for bench marks.
