I propose starting with a minimig and a VGA-LVDS converter off of ebay. Add battery charger and adapters for keyboard/trackpad and replace any motherboard connectors which stick up too much with cables to the outer shell.

Exactly what I'm doing here..., but with a SAM440.

Can you give everyone your user name and password at http://kes-stratford.org.uk, so we can log in and see the picture you're linking to

Or maybe you should upload the image to www.amigaworld.net or use dropbox shared folder instead, or use imageshack or something.

Since I'm too busy to log in anywhere today, are you doing it IN a laptop shell or are you doing a suitcase mod?

It's currently sitting inside a hinged desktop case. Once I finalise the VDU and the height (need a half height wifi card or angled connector) it will go into a custom shell that I hope my mate will help me machine.

The wife threw away the briefcase last year as I never used it. Apparently.

In that case it's not EXCACTLY what I proposed, as I propose actually getting it into an existing laptop shell, it just needs to be big enough to accomodate it.

It is possible, I'm 99% certain of it. A 460 would be ideal.

Maybe it look better if you can make your own case design.

OK, but be realistic: do you think that Apple will sell some of his technology (and maybe intellectual properties), even if he doesn't need it anymore?

There are already existing solutions where to start from for this project: QEmu, PeerPC, and SheepShaver.

I think that a good execution speed can be reachable with a proper JIT (better using x64) and middle-level machine, and an acceptable speed (e.g. like low-end PowerPCs) for low-end PCs.

@cdimauro

does my ms surface with uae and aros68k count as amiga laptop? at least i can code hollywood when- and wherever i need, right?

@wawa

Maybe if it booted straight into Amiga OS/AROS from power up. I suppose ultimately it's down to whether you gat that feeling of using an Amiga from it.

@Rob

likely it could be set up to boot stright into uae, but win8 is far too useful to skip it. what concerns the feeling, nah i dont have nor care muvh such feeling, except when looking at aros68k screen when working on it. its just a tool to have mobile amiga (substitute) underway and be able to work on it.

on the other hand, would rebranded limepc provide anymore "amiga" feeling? i doubt. and it would be likely significantly slower. whatever, as it stands up till now genuine amiga 68k is the only "amiga os" running on mobile devices
;)

os4 needs to catch up!

There's nothing after the Commodore bankrupt that can be called "Amiga". The Amiga was a wonderful, unrepeated and may be unrepeatable combination of custom hardware and (mostly) ad hoc o.s..

As coder, it was a pleasure to program thanks to it's 68K (CISC rulez!), custom chipset with ad hoc coprocessors, and the possibility to directly hit the hardware.

So there's also no Amiga "classic" neither AmigaNG (or Amiga NG; whatever): there was only and simply the Amiga. All the staff that came later is either post-Amiga or AmigaOne, and is a PC with just the CPU (a RISC!) replaced...

@wawa

I'm glad the Limebook didn't happen for OS4 since such slow hardware would have sucked.

@Rob

+1 on that!

" is a PC with just the CPU (a RISC!) replaced..."

RISC means more work in assembly level, but native AOS4 can execute 68k code as well (almost as native).

Times when Amiga SW+HW combination could do a lot of unique things is over for now. (and we could do a lot same+new stuff in SW now, with 1Ghz+CPUs, but we lack manpower)
My most enjoyable CBM Amiga was/is Amiga4000, already it had parts like chunky pixel GPU that had nothing to do with "AmigaHW", etc... I learned that the OS is more important than A4k HW.

So, for me, "Amiga" is where the current OS is.
And AmigaLike can also be as nice to use (or nicer) than the real thing.


btw. I would not mind being able to do some special things on NG AmigaHW ... if it had things like DTV OUT (broadcast quality), it would enable some cool stuff...

I'd just like my AmigaOne "Back For The Future". Used to do this with even an A500:
Net and printer. Too much to whine about;) Now we need offcourse the camera usb.
I know it works but how do You get these pictures out aside from the Amiga's screen?

On paper without all the fuss. (Not Net)

At my child times we took three pictures with a video camera rolling RGB screens with Digiview Gold to get a colour picture. The A500 did the Job. Also B/W animation in a single disk, running from boot.

With all the new technology I can not understand the situation.

I'd buy a laptop with these abilities or before more happily upgrade the OS4 again with $$$ or £££ or €..

In all other operating system you put hardware specific stuff in a driver, so you can replace the driver, when you get better hardware.

if you want to hit hardware on a modern computer, you will need to scan the PCI bus, find the product and manufacture id, then ask for access to the hardware, then you get a memory IO, and port IO address of PCI bus, now that you have this you can poke the hardware.

As for writing 68k assembler I agree it's easy because of naming of the instructions, they are easier to memorize then for example powerpc assembler, where you have to memorize more names, 680x0 assembler uses its syntax to differentiate between operation code, powerpc does not, the name of instruction is the only thing that decides what operation code to be used (1 to 1).

a "Word" is also not the same for powerpc as 680x0, a word is 32bit on powerpc, on 680x0 its 16bit, a half word is 16bit on powerpc.

Almost all of PowerPC instructions have 3 registers as parameters where 1 of registers are optional (or the 2en parameter).

An example:

680x0: move.b
PowerPC: lbz and stz

680x0: move.w
PowerPC: lhz and sth

680x0: move.l
PowerPC: lwz and stw

I think once you memorize how the names are logically organized it can be as easy to program as 680x0 assembler.

Also, using the ETLAs CISC and RISC is not very meaningful, I prefer load/store architecture to describe ARM and POWER (the PC was dropped in 2006 .

Basically, in 68k you could modify memory mapped addresses directly, in a load/store arch the only two instructions (where an instruction is a group of assembly mnemonics rather than a single one) are load and store.

And if you wanted to I bet you could write a layer that translates between load.w and lwz, or even move.l address,register to lwz and register,address to stw

move from register to register is of course no different, while a move from address1 to address two would take a load AND a store. With a spare temp-reg.

@thread

Unless there are two companies with the same name, I saw Tsinghua Tongfang (THTF, China) Co. Ltd. (Limebook) monitors at Walmart yesterday.

At Walmart the branding name is "Tong Fang Global", but a quick search shows
Quote:

Tong Fang Global is a leading Chinese Electrical Manufacturer. It forms part of the Tsinghua Tong Fang Co Ltd.

Wow, were we almost competing with Walmart for product? Heh.
