Odd problems with a QL and Trump Card (Rich Mellor) -- Message: 1 Date: Sat, 27 Mar 2010 13:24:29 + From: Rich Mellor r...@rwapservices.co.uk To: ql-us...@q-v-d.com Cc: Howard howard.thom...@ntlworld.com Subject: [Ql-Users] Odd problems with a QL and Trump Card Message-ID: 4bae070d.7060...@rwapservices.co.uk Content-Type: text/plain; charset=ISO-8859-1; format=flowed I have a customer who purchased a second hand QL off ebay and a Trump Card from me. The QL was in a poor state and would not start - but he fetched all the chips out and reseated them, so it starts fine. However, as soon as he plugged the Trump Card into the machine - it gets through the chequer-board memory test - then comes up with a grey screen. The PSU seemed under powered, so he has replaced the PSU and the Trump Card + QL then started fine a couple of times. However, having left the computer and Trump Card for a few days - he is back to the same problem on start-up Does anyone have any suggestions as to what this may be - I wonder if it could be the 68008 chip?? back in the days of yore, we used to 'cure' QL's with marginal power problems by replacing the 2 ROM's with a CMOS EPROM, really dropped the milliamp draw of the QL's power supply bits. Somewhere in the back of my mind it seems that it reduced the total draw by up to 30% Actually, replacing the JS ROMs by a Minerva allowed the QL with trump card to start up but it only reported 640K in the end (after displaying the huge numbers on screen) so I guess there is a memory fault on the Trump Card. Odd that it started fine on my QL... Minerva with just the standard QL did not report any errors, so we know it is the Trump Card. Is there a way of interpreting the numbers displayed by Minerva to ascertain which chip is faulty? Possibly not as the numbers seem to be different every time! -- Rich Mellor RWAP Services http://www.rwapsoftware.co.uk http://www.rwapservices.co.uk -- Try out our new site: http://sellmyretro.com ___ QL-Users Mailing List http://www.q-v-d.demon.co.uk/smsqe.htm

Download the utilities disk ( http://tfs.firshman.co.uk/ql/fminerva.htm) and lrun memory_bas - I think that is the one. but that is for the standard QL. I forget whether it gives any info about expansions. It is so long since I thought about such things. I will RTFM when I get home.
