STE: Thanks for the memory?

[Steve]

@LeakyBatz there isn't an STe specific PSU upgrade kit. They're PSU specific. So you would need to check what PSU you have, and order the corresponding kit.

Cheers, have placed an order!

Thanks @exxos I'll have a look at them.

Regarding the memory, errr.....I guess I need to pull out my 386 & check them. They are from a bag of previously tested sticks, though.

Would this be the kit for recapping the Atari STE PSU?

Your 386 may well have parity RAM installed so be sure to check. If it has 8 RAM IC's it should be OK, however if it only has 3 IC's you'll need to check the chips against their data sheets as I have run into 3 chip SIMMs with 2 x 4 bit ICs and a 1 bit parity IC.

I do have 1mb over 4 256kb sticks which are for Atari's. I get the same results with them. I'll check through my 1mb to see if there are any that non parity

No worries let us know how it goes.

Thanks @exxos , the diag cartridge arrived earlier this week. I decided to just use 2 256kb sticks until it's running properly.

I set up the cartridge for STE

I'm getting this with a continuous tone...

TeraTerm just shows this "16 Checking exception handling..." message.

Anyone else seen this before? Google AI suggested it might be the MFP chip?

This is the service manual, try section 3 starting at page 25.

BTW did you swap to non parity RAM? If not you should do so.

[LeakyBatz]

Thanks RJ,

I'm using these sticks, I've got 4 of them.

Can you get a sharper picture at all, I can't read the numbers on the ICs. Either that or write the numbers in a post.

Hopefully this is better
