svhovater Posted March 5, 2021 Share Posted March 5, 2021 Trying to track an issue. Diagnostics for U1MB, anyone? thanks Steve Quote Link to comment Share on other sites More sharing options...
flashjazzcat Posted March 5, 2021 Share Posted March 5, 2021 If you want to test the extended RAM, XRAM will do. Or is something else acting up? Quote Link to comment Share on other sites More sharing options...
svhovater Posted March 6, 2021 Author Share Posted March 6, 2021 Hi Jon Xram ? Where? as to the problem - I put the U1MB in my 65XE, and that and the Side2 were magnificent. Unfortunately, the power LED doesn't work on that machine, and I neglected to power the machine down before I removed the Side2. Now, the Side2 mostly works - but the real problem comes in when I operate spartados X - from the U1MB. I have the settings to use the 1024 Rambo handler for the ram disk, but after awhile I type "DIR", and get a ton of "symbol undefined" errors. I noticed that when I use a different handler for the U1MB ram - say, the 256 or 320k handlers, I don't see the problem. Or haven't since. My working theory is that the side2 insertion/removal with power on did something to the memory that spartados is bankswitching. But I could just be totally full of beans, too. So - my first step is to "formally" test the extended ram. I'll hunt around for XRAM. Thanks for the tip. Quote Link to comment Share on other sites More sharing options...

_The Doctor__ Posted March 6, 2021 Share Posted March 6, 2021 (edited) really shouldn't damage anything by having a cart come out... unless the cart card edge doesn't have the fingers with differing length to prevent power issues on hot insert/pull of the cart. if the data were damaged you'd think it would fail immediately.. if it's happening after time passes... well then there may be something going thermal. You could get lucky though, a little carbon built up on the cart port or the sides fingers... give it a good cleaning and see if that helps. only other thing would be to put it in another computer and flash/reprogram them while cold or on an exernal programmer... Can't hurt to try them on another machine to make sure where the damage is for the individual parts of this equation...

svhovater Posted March 13, 2021 Author Share Posted March 13, 2021 Finally got back to this - I ran the xram test, and I didn't see any errors. Just for fun, I reflashed the U1MB to 3.10, and haven't seen the problem recur yet. Seems like a Schroedinger thing. When I am *trying* to reproduce the problem, it's rock solid. Sigh.

_The Doctor__ Posted March 13, 2021 Share Posted March 13, 2021 (edited) This is a slight pattern as a handful have re-flashed it and it starts to work again... Edited March 13, 2021 by _The Doctor__ Quote Link to comment Share on other sites More sharing options...
