I have a 300MHz R5200, but I've no idea whether there's a blue wire or not... is this a deal-breaker?
Have a look at it: the voltage regulator is housed in a TO-220 package (See below).
Maybe it works with other PCB versions, but two modules
the blue patch wire I had reworked years ago showed up not to boot into IRIX afterwards though all tests from the PROM monitor ran through error-free. I guess it might have been mere coincidence, but I don´t want to find out that it is the other way and mess up another rare CPU module.
Please look here:
To anyone with
deep (SGI) hardware knowledge and adjacent test equipment:
I´ll gladly send you one of these modules for free to find out what´s the matter
About the time frame: three modules get reworked next week, one of which is sold already, another one i wanted to keep myself.
But I´m as well willing to ship it - on the condition that I get the trade-in RM5271 module later (otherwise the chain gets broken).
Ah, now for the vermouth drop (does one use that phrase in english at all?): Material, Soldering, X-Ray and Shipment still totals to 250 Euro.
It is unlikely that this will change because tere are no hordes of O2-owners who trade in their modules by the dozen.
If still interested please pm me and I´ll gladly tell you my PayPal accredited email address.
