Re: Mess Emulator für diverse Schachcomputer ist fertig!

And more surprises are coming! I will be tomorrow Friday, and all weekend, working on the computers and cartridges that Achim has sent me.

Best,

Re: AW: Mess Emulator für diverse Schachcomputer ist fertig!

If someone sends me any cartridge, I can do the romdump. Although maybe now is not the right time to make shipments!

Re: Counterfeit ICs

Hallo,

These microprocessors, sold by a UK retailer via eBay, are also counterfeit.

Indeed, it also has a /2 divider. The Starndard module has a 4 MHz quartz crystal, and its system clock is 2MHz

Hello,

I perfectly understand why you have chosen that name, and I think we should leave it that way. Don't change anything, please. Thank you.

Hi Franz,

You're right: From an operational point of view, this is true, these are similar programs. But in my opinion Mephisto 1X deserves a place of honour. :)

It was released as a Mephisto...

Re: Counterfeit ICs

Hello,

This case is even more stupid, as UMC did not manufacture any 6502 with the W65C02S8P-10 reference.
