+InsaneMultitasker Posted May 27, 2018 Share Posted May 27, 2018 I have five non-functional Geneve 9640 cards. For some time I've considered what to do with them. I am not interested in investing my time to fix them and have decided to offer them to the community. I obtained the cards during the late 1990s when I temporarily assumed Myarc responsibility from Cecure Electronics. The cards came from Myarc and were never sold due to their inoperable condition. Rest assured these cards are not customer cards. You can read about the repair efforts in Micropendium articles from the period. The cost per card is $50.00USD + shipping. This covers my investment. If you buy a card, you will need to source any missing parts yourself. Schematics are available on WHT. The cards will come with whatever chips are currently installed, untested with no warranty or guarantee of any kind. Last but not least, Richard and I have discussed the future disposition of these cards. We will not accept them for repair. This is primarily an opportunity for those of you who want to own a card that you can learn from and/or repair yourself. 7 Quote Link to comment Share on other sites More sharing options...
Opry99er Posted May 27, 2018 Share Posted May 27, 2018 Damned tempting. Thanks for offering these up. 1 Quote Link to comment Share on other sites More sharing options...
fabrice montupet Posted May 27, 2018 Share Posted May 27, 2018 Thank you Tim for this proposition, I'm tempted the come one of these lovely Geneve to life . And repairing is a fun challenge :-)Do you have a picture of these boards? Can you tell me the shipping price to France? 2 Quote Link to comment Share on other sites More sharing options...
+Ksarul Posted May 27, 2018 Share Posted May 27, 2018 I'd actually be interested in one of these. . . 2 Quote Link to comment Share on other sites More sharing options...
jwild Posted May 27, 2018 Share Posted May 27, 2018 I am inspired by many of you to learn more about the Geneve. I would be interested in one of these cards as well. Sent from my iPhone using Tapatalk 1 Quote Link to comment Share on other sites More sharing options...
+mizapf Posted May 27, 2018 Share Posted May 27, 2018 I know that real iron means a lot more than "just emulation" to many of you, but don't forget that you can easily get some experience with the Geneve on MAME (and then possibly consider to buy a real one). 2 Quote Link to comment Share on other sites More sharing options...
+InsaneMultitasker Posted May 27, 2018 Author Share Posted May 27, 2018 Not to dissuade anyone, just bear in mind these cards will require work and attention. Geneve cards have an internal layer which may require you to check continuity between points,among other things. For those truly interested, please send me a PM to start the process. 1 Quote Link to comment Share on other sites More sharing options...
fabrice montupet Posted May 27, 2018 Share Posted May 27, 2018 Tim, I appreciate your cautions. I am well aware that Genny has a 4 layers PCB, thin traces and proprietary components. But I like this challenge :-)I send you a PM to confirm my interest. 2 Quote Link to comment Share on other sites More sharing options...
TI998owner Posted May 27, 2018 Share Posted May 27, 2018 Hi Tim, I am interested in Non-Working card as well. I also sent you a PM to start the process Thank you for the causion note as well TI998owner Lee 1 Quote Link to comment Share on other sites More sharing options...
+InsaneMultitasker Posted May 27, 2018 Author Share Posted May 27, 2018 4 of the 5 are spoken for at this time. Quote Link to comment Share on other sites More sharing options...
ti99iuc Posted May 27, 2018 Share Posted May 27, 2018 (edited) I would be interested in one in true but i am afraid if important components are missing, i understand good? Edited May 27, 2018 by ti99iuc Quote Link to comment Share on other sites More sharing options...
+InsaneMultitasker Posted May 28, 2018 Author Share Posted May 28, 2018 You understand good. I am looking through my parts for untested components to incude with the card. It will NOT have all components. Here is a picture of the last available Geneve board. 3 Quote Link to comment Share on other sites More sharing options...
Swim Posted May 28, 2018 Share Posted May 28, 2018 I would just like to add to what the insane one has posted we really hope those that take on a broken Geneve have experience soldering/desoldering and tracing circuits point to point. For those that get a board and you find the PAL and/or gate array are fried please contact the insane one or preferably myself since I have the gate arrays and we'll make these limited parts available to you. I would make a suggestion and a tip to you all to just automatically refresh the power supply circuits with new regulators, electrolytics and don't forget the heat sinks. Standard practice is to replace the 16v electrolytics with 35v max. Take care when placing heat sinks that you don't contact a pad that may be close to the area of the heat sink. I have attached a pic of what a refreshed Geneve with the 64k fast RAM and video upgrade looks like to wet your appetites. 3 Quote Link to comment Share on other sites More sharing options...
+InsaneMultitasker Posted May 28, 2018 Author Share Posted May 28, 2018 Swim makes excellent points above in his post. It reminded me to again mention that a case will be important to keep the Geneve from 'rocking' in the PEB. With that a few words of caution for any Myarc card: If a Myarc card is placed into a hard shell case from TI, it is imperative that you remove or file down some of the nubs protruding from the inside of the rear case panel. It is very likely you will short out the card if this is not done properly. Also as Shift838 discovered, be careful with the heat sinks as they can rotate when tightening the screws, which can in turn short the regulator leads and fry the card. You all know that the smoke must remain inside the card. 4 Quote Link to comment Share on other sites More sharing options...
+InsaneMultitasker Posted May 28, 2018 Author Share Posted May 28, 2018 (edited) I was asked privately about the chips included with the other four cards so I am going to share a portion of my response here for everyone: The other sold Geneves are populated with a gate array, 9901, and 9995. The Video RAM was present. Beyond that, common missing chips are v9938, buffer logic chips, SRAM, and/or EPROM. Regulators and capacitors should be replaced. You'll need a 2032 battery/holder. I say this respectfully: if you are not familiar with a Geneve and lack experience repairing boards of this type, my advice is to steer clear. If on the other hand you wish to use this opportunity to learn and can deal with the challenges, then go for it.

+InsaneMultitasker Posted May 29, 2018 Author Share Posted May 29, 2018 All available cards have been spoken for at this time. If one does come available, I will go to the next person on the list and inquire. Thank you all for your interest. 2 Quote Link to comment Share on other sites More sharing options...

+InsaneMultitasker Posted June 14, 2018 Author Share Posted June 14, 2018 All cards have been shipped and/or received. I have started looking through my other equipment: I may have one or two functional Geneve cards and various peripherals to sell at a later date. 3 Quote Link to comment Share on other sites More sharing options...
Opry99er Posted June 14, 2018 Share Posted June 14, 2018 I might be interested in a functional Geneve (with keyboard?). Keep me in mind please, sir. 1 Quote Link to comment Share on other sites More sharing options...

fabrice montupet Posted June 27, 2018 Share Posted June 27, 2018 ... I have received the Geneve 9640 today ! So happy :-) I will have some time soon to begin the restoration, I can't wait! 7 Quote Link to comment Share on other sites More sharing options...
+InsaneMultitasker Posted June 27, 2018 Author Share Posted June 27, 2018 A reminder to everyone - do not take anything for granted. Inspect the solder traces, the solder work, the sockets, etc. Sometimes two memory traces are accidentally connected by stray solder. Sometimes a socket is installed wrong.
