I’ve been using this device https://www.amazon.com.au/gp/product/B01GHKL7HQ/ref=ppxyodtbasintitleo01_s00?ie=UTF8&psc=1 to scan & save Dad’s slide collection, or at least those of which I don’t already have copies. It’s really effective with the thicker plastic-framed transparencies because one of the feed-in attachments is a quick change magazine that can take up to 12 slides in its hopper. That attachment is useless with the thin cardboard-framed slides, they get jammed in the mechanism. For those there is a hinged frame that holds four slides at a time and you manually insert that into the slot in the side. There are indentations to enable accurate placement of the images to be copied. You can select between 5 MP & 10 MP jpgs which are stored on an SD card.
Very fast & effective with slides.

And of course, the late Qld Premier Sir Johannes Bjelke-Petersen referred to news conferences as “feeding the chooks.”

“Palachook.” I like that.

An Apple TV is compact enough to do the TV connection. Just use AirPlay to connect to it.
One of the larger sub-groups of the Mac User Group used to have a bag of various dongles for presenters to connect to a laser/LED projector. About six years ago they started using an Apple TV 3rd gen connected to the projector via HDMI cable. The audio section is covered by a battery-powered PA system connected to microphones or a 3.5mm audio plug.
This way you don’t have to worry about the limited port selection (Thunderbolt3/USB 4.0) on the current M1 MacBook Air/MacBook Pro.
In truth, I doubt you’d even meed a MacBook Pro: a MacBook Air with 512 GB storage, 16 GB Unified Memory & the 8 graphics cores that comes with that combination should be plenty powerful for you.
I’m basing this recommendation on my base model M1 MacBook Air - that has 256 GB storage, 8 GB Unified Memory & 7 graphics cores. All M1 Macs (except the M1 Pro & Max models) have 8 processor cores.

Neighbours at the other end of the block of units who have set up a snooker table in their garage are playing something weird that’s possibly distantly related to a cross between (c)rap “music” & a demented race-call.

Folk often ask “how long will my Mac last & still be relevant?” Well, I bought my 2017 4k iMac (quad-core 3.0 GHz i5) with a dedicated graphics card & 16 GB RAM just six weeks after that model update was released, July 2017. That’s 5 months shy of five years. It’s still going strong, meeting most of my computing needs & has the newest available OS variant installed. One major change made was exchanging the 1.03 TB Fusion drive with a 1 TB SSD.
If I need more capability or speed, I also have an M1 MacBook Air.

WolframAlpha says I have 23,094 days accumulated…

I was getting that way about the middle of 2018, almost collapsed while interstate at my aunt’s funeral. I was diagnosed as anaemic & needed an iron transfusion 3 weeks later.

It's been a bit of a strange day!
First I found a hat full of money.
Then I was chased by an angry man with a guitar…
