Random Ram Test failure #3

Open Boothies opened 2 years ago

Boothies commented 2 years ago

Dear Sir,

first of all thank you very much for developing the REUPlusC2. I never pulled a request before and I hope I´m doing right. After many different tests, the REU seems to work. However, one program (REU-checker) randomly shows errors. After 7 Tests, 5 where "good" and two had different errors

Other Programs / Demos or Games using a REU run fine however. Greetings, Boothies

Boothies, I am not sure what the problem here may be. The timing of my hardware was never intended to be the same as the original REU and there may be some subtle difference causing the problem that I did not find with other programs.

My C64 is back in storage so it may take a little time for me to break everything back out and test with the test program you are using. I will try to get to this in a week or so.

Dear Sir,

I made a 3D Drawing for the REU housing. Of course, I would also like to label it adequately. I stumbled across two Jumpers (P5 & P6). What is it good for? I plan to use two switches on the left site of the cartridge. Can you give it a name?

Sincerely

Boothies

Booties, Please call me Jeff.

P5 is connected to RESET P6 is connected to NMI

Dear Jeff,thank you for the fast response.You told me exactly what I asked, but it did not help me. ;-)I'm a bit confused.Reset and NMI for operation from user side, eg. User Reset BUTTON and NMI SWITCH - lets say for system halt, orSWITCHES to enable the REU ( give the ability) to reset the system or trigger an NMI ?By the way, you see I'm a nope. So please call me Stefan. I'm afraid, I'll ask some more questions ...I'm making 3 housings for your hardware.3D print will take a while. In the meantimeI drew a (lets say) label for the REU. ( it will be printed directly on the surface ).May I send you the draft, to have a look at?Greetings Stefan Von meinem/meiner Galaxy gesendet -------- Ursprüngliche Nachricht --------Von: jburrell7 @.> Datum: 21.04.22 23:42 (GMT+01:00) An: jburrell7/REUPlusC2 @.> Cc: Boothies @.>, Author @.> Betreff: Re: [jburrell7/REUPlusC2] Random Ram Test failure (Issue #3)

Stefan, These are user controls that directly assert signals to the C64.

The RESET switch is tied directly to the C64 reset on the edge connector. Bridging those pins will cause the C64 (and the REU and anything else connected to the RESET line) to do a hard reset as when the C64 is turned on. The intent is to connect these pins to a momentary push button so that the C64 can be reset without cycling the power.

The NMI switch can probably ignored. It is connected to the C64 NMI pin on the edge connector and was put there in case anyone wanted to use it.

This is an example of a switch that would work. Switches like this should be readily available from European electronics distributors.

Stefan, Thank you for your kind offer but I do not require an enclosure for my device. I prefer to keep it open to enable me to probe it for debugging.

Thanks

Jeff
