Hi Robert,
Well you have given me some very good info to start and I sort of suspected the H8000 was the newer IC. Many sites report the speed of the processor but I believe it is as you suggest not the true speed and you need to divide by 2 in order to get the true internal clock speed. The ability to over clock is very interesting and I am sure exceeding certain limits are met with "fatal errors" and then you have a pretty wooden box of spare parts...  LOL. Ultimately I was curious to know if "they" are ever going to go back to the drawing board and develop newer desktop chess computers or just continue to repackage the older ones after re-clocking, dressing up and putting them in newer prettier cases. The technology is certainly there but I am sure they have done marketing research and found that the profits would not be worth the time or cost.  Best regards....    Hondo

So my question is the same with reference to the difference between the H8 and the H8000.

maybe you should ask this question in the .info forum?
http://www.schachcomputer.info/forum/forumdisplay.php?f=2

I know, that there are some people, who know more about CPUs than i do.

What i was told: the H8 seems to have a max. speed of 12 MHz (if you try to overclock it with more than that, it will usually drop back to 10 or 12 MHz; nevertheless a .info-member managed to overclock a Mephisto Mystery to 32 MHz; not less and not more )

The newer H8000 can usually be overclocked to 24(.576) MHz without problems.

The reason: the H8 runs already with 20/24 MHz, but that speed is internally divided by 2, which gives a real speed of 10/12 MHz.

In some manuals (e. g. MM VI) you can find 20 MHz as speed, but that's not the whole truth...


best regards,
Robert

Hi.... thanks for your response,
The following information came from the "wiki-elo-liste" and the computer it is refering to is the Saitek Cougar. As you can plainly see the "Prozessor" clearly refers to the IC and the Programmierer is clearly identified as Frans Morsch. So my question is the same with reference to the difference between the H8 and the H8000. With regards to the importance of this IC it would take a whole new topic  and much time to get into why I think this IC is at the very least a significant factor to be considered before purchasing a computer. That doesn't mean I dont give a great deal to who programs it but the computers ability to "think"  is directly related to the speed and the depth /plys the processor allows. Regards......

SAITEK COUGAR
Prozessor:        H8000, 16 MHz, 8 Bit Singlechip           
Speicher:        32 KB ROM, 1 KB RAM                       
Bibliothek:      6000 HalbzĆ¼ge                         
Programmierer:    Frans Morsch

Hi
Can someone please tell me the difference between chess computers that use the H8 chip as a processor and those that use the H8000? Are they essentially the same or are they significantly different? If they are different, how does having one IC over the other effect the game play/potential of the chess computer? Should one base the purchase of a computer on it's having one of the IC"s as opposed to the other if everything else is pretty much the same? Hope I am being clear in my request and thanks....  Regards    Hondo


I haven't heard of H8000 processor, but just H8000 programmer, H8 processor is common on chess unit. 
Which unit you know uses the H8000?
If I am deciding which chess computer to buy, I think the type of processor is almost the last thing I need to worry.  I would look for the operation of the unit, the look, the feel, and the program strenght before I look for the hardware inside.
