I'm backing! It's looking good. I doubt i'll ever use it. It'll be nice to have though!

I’m backing. I also bought the board, so got to play with it early. Really impressive what the guys have done. I’ve even managed to code a simple Z80 based game for it using the pasmo Z80 compiler and runs everything flawlessly. Can’t wait for the fully finished machine.

Although this project is very late in delivering, it is still on-track to be released and I'm one of the excited backers.

This year is looking much more promising for Spectrum Next... finally..

ive been kicking their arses about the delays, but they seem determned to act like a charity and release a `perfect` product. utterly insane way to manage the project, but the folkin charge have massive egos, and intend to do it only one way. So basically the muppets just keep everyone waiting.....id much rather see an imperfect product relsease and then updated over time.......they never heard of internet patches!?

The damn computer is modular, things couple be swopped out. Anyway, without going into full on rant mode.

if they manage to not bugger it up anymore, should be released by sep.....Image

I avoided joining this kickstarter as I was still livid by the despicable Vega+ indiegogo fiasco. But now.. well, I'm wishing I'd ordered one.

Any change in any feature of the board results in the admins/mods having to pipe all their PMs to /dev/null for at least 6 months, at least some of which is spent by both users, and admins/mod, rocking in the corner and crying to themselves.

Best plan is to wait IMO. You only need to look at the Elite Spectrum, Vega and the C64 Mini to see the kind of rubbish you can end up lumbered with. Best to wait. If other projects are anything to go by, once the fuss has died down there will be a slew of unopened and unwanted machines hitting Ebay/Cash Converters.

The zx spectrum next is quite cool and very nice case, but i prefer the zx evolution.

Purchased it a few years ago and is a lot of fun, also is not just an fpga have a 14mhz real z80, ide, floppy, expansion slots, serial ,parallel can take ps/2 keyboard an mouse or use a real zx spectrum keyboard, sdcard, 2 Sinclair joystick ports and kempston joystick support, 4 megs of ram etc. Have software support for a lot of the Russian bizarre software.

What's wrong with the c64 mini? I thought it was supposed to be decent?

When I reviewed it I found it laggy (even after the firmware update) and couldn't do anything a Pi could do far better. The included joystick was a total joke as well. Will stick with the real thing or a Pi.

finally showing some sort of integration between the next and the pi....

Hopefully this can be developed over time.

While I don't do Spectrum Retro (Or RetroModern in the case of the Next I suppose), I did own a Spectrum +2 for longer than I owned my Electron (but that was mainly because all my friends had spectrums so I jumped ship). That would have been an amazing feature BITD. Now we just need someone to do it with the Beeb somehow.

(That is, tape images on sdcard fed from a Pi into a micro (by audio? Or by DMA? Could be a role for Dominic's 1MHz Pi))

Not audio as they said it doesn't suffer issue that Tzxdunio suffers. I am sure UART was mentioned.

Edit: Says Loaded directly into PI Memory, decoded and then transferred digitally back to the Next.

The “tape” signals used by some home computers are essentially digital pulses. Hence it is possible to transfer (load/save etc.) without going via analogue audio levels. Of course, not very practical for existing machines, as it would require modifications to their circuitry.

Think of it as a serial bit stream, but with variable pulse lengths.

someone somewhere mentioned running cpm on the next, but i have no idea where that project got to...if very far.

HOWEVER i just found this vid.......https://youtu.be/UZo6REwS9Rg

its tuff to follow lol

However i wondered if his mmu system, could be emulated on the pi ? doesnt the pitube system work off dhared memory space ?

If it makes it to wild I seriously like the look of the Mega65. It would scratch the commadore itch, has the modern ways to get software in to it, hdmi and all the c64 and c65 modes.

If course it also runs its FPGA 4502 core at 48mhz, vic IV graphics capable of 256 colour, loads of ram and other stuff that make it a very modern experience. I guess kinda what the bloke wants for his replacement for the c64 and more but isn’t sticking to must be a real cpu.

Ok maybe I’ll be priced well out when it makes market proper but still think it’s a brilliant idea and a lot of work seems to be going into it to make it a great experience.

It does look interesting. I can see my retro desk getting filled with a Spectrum Next (if/when they do a second run), a Commander X16 and perhaps the Mega65.

am troubled in my waters....

some of the leading devs on the next are rejecting the copro idea, which is a bit disturbing.
think the tube interface makes more sense when the relative processing power of the native 6502 and the co-processor are not too far apart. Then the co-processor is not being io starved and artificially slowed down.
The situation today with the pi is that the pi is much faster than the z80 and the peripheral set plus native os on the pi is much more sophisticated. I think a tube-like interface would actually slow down the pi considerably while it waits for the z80 to respond since the volume of data from much faster processor goes up. Using the existing uart you could still operate this way with message passing using a 2mbps serial link. This is almost 200 KB per second. The original bbc tube was slower than this I think but was also message passing using a parallel 8-bit data bus. The pi peripheral set, though not always well documented, gives opportunity to exchange data at the hardware level which is what we would like to access. This is much higher speed than possible with the cpu at the software or os level. That's kind of where we are looking now.
would anyone involved in the tube project, care to analyse that thinking, my gut tells me there are some hoes in it? No point in me guessing tho...

thoughts plz?

edit, for clarity....
We are not going to follow what was done on the beeb because just leaving the pi as a native arm gets you the best of what is possible. However, that doesn't really get in the way of someone wanting to emulate other processors on the pi and exchange messages. At the moment the next and pi mainly communicate through a uart connected to a pi shell so you have a text terminal interface to the pi. You could run cpu emulators, send basic or other code for execution, etc, and receive output back also via the uart. The uart can run at up to 2mbps.
The beeb tube interface is integrated into bbc basic hooks and that does not exist now in nextzxos. There is a plan, subject to fpga space, for the hardware and the pi to be further integrated to exchange more things without cpu involvement.
