I waited for the B+ to arrive with its four USB ports and ethernet port before climbing aboard the Pi adventure. I now find that B's and Zeroe W's are often ideal for the kinds of Application Engines I create so have gravitated towards those for deployment while using more recent Pi's for development use.
You are correct. My human Memory fails me sometimes, and I have not used my original RPi in a few years.W. H. Heydt wrote: ↑Fri Jul 05, 2019 4:42 pmNot at initial launch, you didn't. The early boards were 256MB. It wasn't until after the Rev. 2.0 that the Model B got 512MB.
Both have been mentioned as *possible* products.
Extraordinarily unlikely on anything other than CM boards.eMMC
Heh. Go read the CM forum. The BCM2711 has *one* PCIe lane and it's dedicated to feeding USB 3. What I think you're asking for is one or more directly exposed PCIe lanes.PCIe
Do this over USB 3, or hope for faster PCIe to USB to get USB 3.1.eSATA
A ton of add-on units are available. With multiple I2C busses available, one may no longer be constrained to a single mount location.RTC
Those would take a faster VC6 or follow on VideoCore. And remember faster == more heat. This can be mitigated by using a smaller process node, but I think it's going to be quite a while before Broadcom goes that route.4Kp60 HDMI on both ports
Where are you going to put them?Full-size HDMI sockets
Very minor use case, what with PoE header or powering through GPIO. Space is also an issue.Additional power-in header
Already exist. Go out and buy one.UPS capability
If anything, this would be a PoE HAT function.Wake-On-LAN
Kind of goes with the territory. Just be patient.Make even faster
It is unclear that this would be of more that minimal use. So far, 4 cores is pretty much the sweet spot for price/performance.Have more cores
Some time before 2038, but there is no rush. In the mean time it would be wasteful of resources to maintain two versions of Raspbian, and while B+ (which you appear to like a lot) and Pi0/Pi0W exist, 32-bit Raspbian is required.64-bit Raspbian
If I've read a couple of comments properly, this could--theoretically--be done now. But it would be expensive, it's possible that RAM modules the fit the available space may not be on the market, and it assumes that all the address lines from the MMU are exposed. In theory (again, based on a comment from an engineer), the BCM2711 can address 32GB of RAM, but where are you going to put it? For that matter, how many people could even make use of it?8GB version
Both related. If it's critical, reduce the clock speed. The only alternative would be a die shrink, and as I noted above, that isn't going to happen any time soon. Plus...these are the antithesis of your "asks" of being faster and with more cores. Make up your mind about what you actually want.Reduce heat
Reduce power consumption
Get a CM/CM3/CM3+. They all have two.Additional Camera inputs
Probably expensive to add, for few use cases.HDMI input
Expensive to add and unless multiplexed onto exist pins, no space.Add analogue input capability
Get a CM/CM3/CM3+. They all expose all the GPIO (and other iterfaces) available on the SoC.Additional GPIO pins
yeah... Pretty much none of them are feasible, let alone practical. About the only thing that one could expect from that list is the next Pi will be faster.Not all of those will be possible, feasible, practical, have a business case for them, will fit within current Pi constraints, or fit with RPF/RPT plans or roadmap at the current time.
I'm not asking for anything, just noting what others have said would be desirable to have in their view. And I acknowledged it might not happen, and some things might require a new or upgraded SoC or a change in thinking and plans, which equally might or might not happen.
No such animal as Pi2B+. There is a B+ and there are the Pi2Bv1.1 and Pi2Bv1.2, the later being an underclocked Pi3B without WiFi.

One, actually. The BCM2836 was a revision of the BCM2835 sufficient to give it a new designation. Likewise the BCM2837. The change from BCM2837A0 to BCM2837B0 wasn't even significant enough to get a new part number. The only "from the ground up" redesign that the Pi has seen so far is the BCM2711 used on the Pi4B. That's why the Pi2 followed the Pi1 so quickly and the Pi3 followed rapidly from the Pi2. Neither one used a really new chip design.
I stand corrected and edited my other post.W. H. Heydt wrote: ↑Fri Jul 05, 2019 8:56 pmNo such animal as Pi2B+. There is a B+ and there are the Pi2Bv1.1 and Pi2Bv1.2, the later being an underclocked Pi3B without WiFi.

I'm using Kicad to design PCBs. It seems to work mostly OK. I've had a few glitches. Currently I'm running Kicad 5.1.2 on Raspbian Buster (upgraded from Stretch, as a Buster image wasn't available when I installed it) on a Pi 3B+.
I do not generally use Raspbian or Linux either. Though I do use every model of RPi as a full blown desktop computer, including for development.Gavinmc42 wrote: RPF make a point of keeping Raspbian compatible with the single core Pi's the Zero and B+.
But I don't use Raspbian on those and have not for years now.
Only one box with an old model 256MB A is using it.
Interestingly it is a dual monitor Pi but done with an expensive HDMI switch box.
What software could there be that you would need? As what you list below is availible (ok different CAD's though just as capable).Now I have a Pi4 that can be used to make the code for those older, smaller and still perfectly usable Pi's.
That nearly closes the loop for me, develop on a Pi for all Pi's.
There is some PC apps I use that need Pi versions.
Too many options for CAD. Though have you tried RiscPCB for PCB design and layout software? It will even produce the Gerbers for you. And it runs on the RPi even in the newest RISC OS releases so far.FreeCAD is coming along, just some OpenGL stuff to sort?.
PCB design software is the last on my list of must have software.
The dual screen Pi4 makes that CAD stuff bearable to use now.
I do not have any A models at all. Have thought about getting one, though never did.Still need to find something to do with my A+ and 3A+ versions.
