Game Console Prototypes

[skaar]

Here's a prototype of one of the SNES CD-ROM addons,
I do not know which of the 3 formats this is...

It looks like someone was beaten to death for/with that one or something - is that blood?

Yes, it is the blood of its now deceased previous owner.

yeah I know, lol

The prototype SNES CD unit (the one with the red stuff) is the Sony version.

okay cool, i wasn't really sure.

People don't often show handheld protos so here are a couple of Sega handheld prototypes I have.

[poloplayr]

BuyAtari, very cool protos... do you have any background info on those?

Also, was almost expecting you to chime in re the SNES CD judging from that semi-controversial thread on assemblergames' forum

I got them from Clint Dyer an old time big handheld collector he used to work at Sega. They were rescued from the trash.

I've said all I have to say about the SNES CD. There are far too many "experts" and in the end people can and will believe what they want to.

the rumored Namco 16-bit console, 1989






Could this be what happened to the Namco console,
was it used as the NA-1 and NA-2 arcade boards?







Don't know for certain, but I suspect this is the case.

PSP, 2003

I find that incredibly hard to believe. Early PSP models looked identical to the final model. PSP development was pushed out the door so fast that the door mechanisms on the first million units still had the little arm to slide open the "floppy-style" cover that was removed from the UMDs.

I particularly like the button on the top left that says "Analog". It's like someone saw a prototype PSP and described it to an artist who interpreted it literally.

not the full image,but what it was gonna look like. (Playstation 3)
I can confirm this image, due to I read in PSM magazine along time ago what it was going to include and this is it.

here's a comparison, lol

Was this suppose to be a joke to me or at sony?

Apparently your pic is wrong for the "new" ps3 due to it has a HDMI input in the back. Well at least my 60Gb does, don't know about the newer ones.

Also that's why my picture is of the prototype sony advertised with; at E3,magazines,etc.

The Konix Multisystem was a pretty neat machine for it's time, although the odd design might have limited it to mostly driving games/flight sims. I can't imagine playing a Defender clone with a steering wheel. Although they did make joysticks too (which makes me wonder if they were going to make the Konix joysticks Atari compatible).

According to info from Retro Gamer, Lucasfilm was interested in buying into the Multisystem console, but the company owner wanted to keep it British. It's a shame that it never came out, although I can't see it doing well against Nintendo here in the US. Especially with it's steering wheel design making it seem like it has limited gameplay control. But who knows how things might have gone if LucasArts had bought the design. Imagine higher quality first person flight/driving games like Ballblazer, Rescue on Fractalus, The Eidolon, and all the Star Wars games they would have put out on the newly christened LucasArts Multisystem. Woo! Brain melt!

The "Lie" is the fact that sony promised the PS3 could push 120 frames per second out of duel HDMI ports. One was cut from the final model.

I'd hardly consider that system a prototype, it was made by the marketing division, not the engineers.

The Jaguar 2 has seven processors, which are contained in three chips.
Two of the chips are proprietary designs, nicknamed "Tom" and "Jerry".
The third chip is a standard Motorola 68EC020 used as a coprocessor.
Tom and Jerry are built using an 0.3 micron silicon process. With
proper programming, all seven processors can run in parallel.

- "Tom"
- 1,250,000 transistors, 292 pins
- Graphics Processing Unit (processor #1)
- 64-bit RISC architecture (64/128 register processor)
- 64 registers of 128 bits wide (shadow-buffering)
- Has access to all 2 x 64 bits of the system bus
- Can read 128 bits of data in one instruction
- Rated at 127.902 MIPS (million instructions per second)
- Runs at 63.951 MHz
- 2 x 32K bytes of zero wait-state internal SRAM (matrix)
- Performs a wide range of high-speed graphic effects
- Programmable
- Object processor (processor #2)

video architectures, such as a sprite engine, a pixel-mapped
display, a character-mapped system, and others.

- 8K read buffer (fifo)
- 8K write buffer (lifo)

- 64 bits
- Programmable risc processor

- capable of doing about 900000 texture-mapped polyons,
without textures there can do 2500000 polyons.

- J/MPEG "COMBI" Chip (processor #5)
- 64 bits
- not programmable!
- 8K own data rom (with sinus) table
- 128K CACHE (fifo)
- realtime J/MPEG decompression via CACHE (fifo)
- DRAM memory controller
- 4 x 64 bits
- Accesses the DRAM directly

- "Jerry"
- 900,000 transistors, 196 pins
- Digital Signal Processor (processor #6)
- 32 bits (32-bit registers)
- Rated at 53,3 MIPS (million instructions per second)
- Runs at 53.3 MHz
- Same RISC core as the Graphics Processing Unit
- Not limited to sound generation
- 96K bytes of zero wait-state internal SRAM
- CD-quality sound (16-bit stereo 50KHz)
- Number of sound channels limited by software (minimum 16!!)
- Two DACs (stereo) convert digital data to analog sound
signals
- Full stereo capabilities

synthesis
- A clock control block, incorporating timers, and a UART

- Motorola 68EC020 (processor #7)
- Runs at 26.590MHz
- perfect 68000 emulation
- General purpose control processor

Communication is performed with a high speed 64-bit data bus, rated
at 2400 megabits/second. The 68000 is only able to access 16 bits
of this bus at a time.

The Jaguar 2 contains eight megabytes (64 megabits) of fast
page-mode DRAM, in eight chips with 1024 K each.
