Hi Folks, long story but short answer. Its the upper memory that is defectiv on my machine. But here the story why i am so shure about it. I red all the comments you all gave me to that particular problem and tried to test everything you told me...the easiest was the test about the bad GTIA...i started Ballblazer from my UltimateCartridge. Because it seams to work without any graficerrors - conclusion is "GTIA Okay"!!! Then i started a lot of different memory testingtools with a lot of different results. Some tell me that memory is defectiv some don't. A lot of memory testing!!! But at the and i decided...to solder the DRAMs out and put them into sockets (fu.... i have a lot of sockets but aspecially not the 18 pin ones)...so i did something that i real DON'T like...i REALY REALY DON't like...something i hate. I "piggybacked" all memory chips with new one... guess what happend....??? Internal memorytest finished without erros! now its time for me to get sockets and than the machine gets new socketed DRAMs tomorrow Thanx a lot for your help!!! Best regards MaG

thanx a lot...i will try that in the comming days....thanx for your help....but RAMs arn't the problem...for a dead XEGS i have some new NEC 41464 RAMs left that work well in the XEGS. Regards MaG

thanx for your help... do i understand right? the 4 bigger blocks showing the extended memory? i never saw that on other 130XE machines before! Regards MaG

Hi Folks, as my start into that forum i cam directly with the problem and questions on a defect of an 130XE that i never saw befor. I hope somebody can halp me or give me a little hint were i can search to solve this kind of problem. okay whats the problem on that special machine. It seams to work fine. it starts, it runs basic, but....the memorytest shows some strange blocks i never seen before on those machines. The short (with Basic loaded) and the long (without Basic loaded) Memorytest show 40/48 blocks of RAM in the first run they all ar white...no red/brown defectiv memoryblocks...but at the and of the first run happens that what i never seen befor in the internal memory test. under the 40/48 RAM blocks were shown 4 bigger brown blocks...see pictures short memorytest (with Basic loaded): long memorytest (Basic not loaded): becaus this problem is special and because some more 130xe mainboards are sleeping in my cellar waiting to be tested i bought the SysCheck Module from tf_hh i started the machine...the MEM Test runs...tells me everything is fine. ROM Checksumm also is fine. in a conversation with tf_hh he told me to boot the machine and try POKE 54017,252. He told me if the machine get stuck it can't be the MMU or the PIA that causes the problem. this happens after typing POKE 54017,252 and hit return. this is the Mainboard of the 130XE with that special problem. does anyone have an idea what the problem can be? can anyone tell me what program i need to test the upper 64KB of RAM of an 130XE? i have two other 130XE that run normal (on both i had to exchange some of the RAM-ICs. but they have an other problem to. at first bootup he boots into Basci normaly but the screen is only black and white and the charakters look a little like a checkerboard. After turning of and on again it mostliy boots up normaly with color screen! Does anyone know what the reason for that problem can be? Thanx a lot!!! MaG

Hi Jürgen, do you allready have one SysCheck left to buy? Hallo Jürgen...hast du noch ein SysCheck Modul übrig? Ich bin interessiert...habe einen 130XE mit merkwürdigem defekt vor mir und ich denke dein Modul könnte mir weiter helfen. Viele Grüße Matthias

is it already possible to get one of this turbofrezer moduls and also this PBI adaptor? Best Regards MaG2k

i contacted him via PM weeks ago...no reaction till now!

@simius: looks realy great the pile of boards. hope to get one to two of them too. but as mytekcontols allready said take all the time you need. and dont stress yourselfe. regards MaG2k
