Tinkering for some more fresh air for the PFM Geneve.

Schmitzi, do you have the 384k PFM+ mod? If so can you possibly get a sharper shot of the backside of the Geneve, it may help me to repair mine, as I'd had a wire or two, in the past break loose and when I tried to locate the positions that they were in, may have soldered them to the wrong points. my PFM Geneve just hangs at the initial screen. If any other fellow PFM+ owners could,maybe you would share your Geneve backside, may have been more than one way it wad done. thanks.

Understood, this is just misplaced wires and I do fix my stuff, as I can. Repairing a Corcomp Ramdisk and almost have my 2 Horizon 4000b's done. Just need wire routes.Not easy to find as there are no schematics out there for the PFM mods.

Ooh. Sound like an update to a doc that doesn't exist needs to happen... :)

 

 

Well Schmitzi's card from his photos look the same as mine on the front, so is he has the same pfm on his Geneve, if I can get a closet look at his wires on the back, may help me to repair mine.

Mine is still in the recovery room, but I should have it next week.

Just a good view of the back, of the card as it is shown in post #25. I just need a closer, sharper, more focused image of the backside to see where the wires are routed and soldered. Thanks for your help and time.

@RickyDean  and on @fabrice montupet´s homepage you can find detailed informations about all mods:

 

http://www.ti99.com/geneve/index.php

 

 

Thanks Schmitzi. I guess the next question would be for the InsaneOne.  @InsaneMultitasker

Would the wiring for each specific mod 384k PFM, 512K PFM, have been performed the same way. All wires soldered for the 384k PFM, for example, the same. There would be no variation of connection points would there?

No.  There are multiple variations of both the memory upgrade and PFM upgrade.  While the two were often installed together, the owner determined whether to do so.  Wire management wasn't considered all that important at the time; @fabrice montupet would have been a great influence back then.

There is the BOOT ROM upgrade (deprecated, rarely seen), the PFM, PFM+, and PFM512.  The 384K upgrade was performed using 3x128K chips and later the 512K chip that Fabrice documented. 

Throw some pictures front/back of your card and the flying wires over in the Myarc repair topic.

One more cooler for the HFDC.

 

( And I found a RSIC-1, so maybe this will be a complete Myarc system 😍 )

I find it very interesting to see your modifications, folks. However, I would find it even better if you would write a few lines about it.

 

What exactly do we see for hardware?

What is the purpose of the modification?

How does the system look in operation?

 

For example, I ask myself that right from the first post. Where is the keyboard left?

 

So a little more detailed reports gentlemen. ;-)

 

Cheers
