Stuart Posted May 2, 2019 Share Posted May 2, 2019 (edited) I've been given some chips to pass on to someone who can make use of them: -- V9958 VDP -- 5 off 41464 RAMs -- CXA1645P RGB to composite encoder -- some 74HC154 -- some GAL16V8D -- some 74HC138 -- some 74HC139 'Free' - but £2 + cost of postage from me in the UK to wherever you are. Payment required by PayPal once posted and I know the actual postage cost. If you're interested, let me know.

Seems to be a reasonable source. 1 Quote Link to comment Share on other sites More sharing options...

I ordered 4 from him, 1 the first time and my Swan was good. I went ahead and ordered 3 more, received them today, got home from work at 11:30pm, and plugged them into my Geneve. 1 of these gives me a swan, the 2nd would not activate the screen, no signal, and the 3rd had the swan chopped up into squares. I will try to do a more detailed test Monday morning before work, but I have got a lot to do before my vacation starts Friday. I'll take pics then. 1 Quote Link to comment Share on other sites More sharing options...
RickyDean Posted September 19, 2022 Share Posted September 19, 2022 We'll this is what I get when I plug in two of my recently received v9938's. 1. First chip, just a no signal on my monitor. 2. 2nd chip, The one I bought two weeks ago and received last week, mid week, gives a good swan, and one of these received yesterday, shows a good swan. I will need to contact the seller. Quote Link to comment Share on other sites More sharing options...
RickyDean Posted September 20, 2022 Share Posted September 20, 2022 @KsarulI reported my findings with the seller, with pictures. He asked me to clean the pins, which I hadn't done. After doing so, each chip worked, producing a beautiful swan at start up. The words were not corrupt either. I probably should have done this first, but considering that he said they were tested, I "ass-umed" they should have worked right off the bat. Which I an relieved to see, considering the rarity of the chips. 3 Quote Link to comment Share on other sites More sharing options...

Thanks for the update on your purchase! 1 Quote Link to comment Share on other sites More sharing options...
+FarmerPotato Posted September 21, 2022 Share Posted September 21, 2022 What do you do to clean the pins? I have isopropyl 99% and TechSpray, but I haven’t tried it on old metal. 1 Quote Link to comment Share on other sites More sharing options...

I have isopropyl 99% and TechSpray, but I haven’t tried it on old metal. I used 91 % isopropyl and a pencil eraser. Took a q-tip and washed the pins first, front and back, then after drying gently rubbed the eraser on the pins, front and back, the used a clean q-tip end and alcohol, wiped them clean again. Then dried them, good to go. Quote Link to comment Share on other sites More sharing options...
