Side note.. I found some CT-1024 documentation online and it suggested 110 baud. So I set it at that.. it generates nothing but the occasional 8 now. I'm interested to see how much of my issue is RAM... I've suspected RAM from the start with a lot of this and have some NOS MM2102N chips coming to try out. I'm assuming I can piggyback those and see if we get anywhere. -----Original Message----- From: cctalk [mailto:cctalk-bounces at classiccmp.org] On Behalf Of Brad Sent: Friday, October 16, 2015 1:49 PM To: 'General Discussion: On-Topic and Off-Topic Posts' <cctalk at classiccmp.org> Subject: SWTPC CT1024 While I was fooling around with my ASCI I decided to test the serial connection to my PC. The only thing I had available was my CT-1024 terminal with the optional serial board. This unit never worked when I got it. Thought it was its ancient and probably non functional PSU, but after hooking it up to a bench PSU same issues: 1) Unstable video display with large whitish band in the middle. 2) No response to keypresses. 3) Field of blinking ? marks if cursor is switched off, garbled one line of random characters up top if switched on. When I connected it to my PC running PUTTY via serial cable, I fully expected it to do nothing. But to my surprise, it generates a continuous stream of Js (punctuated by the odd H) on the PUTTY screen if the RECV switch is off. If I hit Break, it generates a whole bunch of Bs. If I switch the RECV switch ON, the Js stop but I can still generate Bs with the Break key. One thing I'm wondering now that I've switched power supplies and the video situation isn't cleared up.. I'm wondering if this thing was set up to connect to a composite monitor at all? I've seen pictures of the CT1024 with a Sanyo monitor just like mine.. but on the Sanyo it does the same thing it does on all the others. Anyway, thoughts/ideas welcome. Would love to get this thing running again. ----- No virus found in this message. Checked by AVG - www.avg.com Version: 2015.0.6172 / Virus Database: 4447/10805 - Release Date: 10/12/15

Could there be a bad smoothing or decoupling capacitor on a power line derived somewhere within the unit itself, maybe a one to two hundred or so volt supply to the video output stage coming from the horizontal output stage? (I've no experince of this terminal so this is just a shot in the dark.) Regards, Peter Coghlan.
