Help with CPLD Mach/Cypress CyberStorm MK3

[Boot_WB]

4) Is it possible to delock the Mach/Cypress for reading them on my eprom programmator ?

Probably not. Iirc from reading up on these many years ago they have a read-protect circuit which is literally burned out by the manufacture after the cpld is programmed. It can't be un-protected  - this scenario is exactly what the protection is there to prevent.

DCE/Phase5 would have wanted to protect the IP contained in those chips, so it's almost certain they will have protected them.

So, I give these 800 € for the four rev4 Mach/Cypress files .jed by Paypal, IBAN or cash...

Good luck with that.

EDIT: Thomas Dellert has since passed away (RIP) so tracking down the files may now prove impossible anyway.

Nice piece of kit, damned expensive though!

/me rummages through geek drawer and by unlikely chance happens to come up with...

...a set of CPLDs desoldered from (iirc) a DCE Cyberstorm PPC. The PPC was non-working, possibly due to failure of the CPLDs, possibly failure of the PPC - it was undiagnosed.
I'd stripped the board and sourced a complete set of replacement buffer ICs, just never got around to measuring the values of the passive components and rebuilding it.

They've not been very well stored I'm afraid, so there are bent legs, but at least they have been stored in a sealed plastic container so they are clean and have been protected from ESD.

You're welcome to them if you want them, just let me know you're address.
