RE: Sparc IPX fun

It is also possible to repair idprom/nvram without any expensive parts - https://ideafix.name/?p=4713 you can use a google translate. The main problem is to restore nvram, not a battery.

Heh cool. For reference this guide went up about the same time as I started thinking about fixing up mine. Damn, it’s been a year, I’ve been slacking off. 


It’s a two parter, see the second part where he uses a glitch works module as well which appears closer. GW-48T02-1 the module I used comes with the oscillator, battery and modules all assembled, if you have no fear of melting it all with your soldering iron it may be better 😁


I’m looking to replace the fans as well as they are noisey, although I think it’s actually the HDD making most of the noise.

Well considering that my current modification involves a piece of one
twisted pair from some leftover bulk Ethernet cable and a PCB-mount 2032
coin cell holder held down with hot glue, I can probably handle slightly
bent pins. :)

I picked up two of the GW-48T08-1. They work but may not be the best as they are much longer than the NVRAM module, so I had to bend the legs that I used inwards.


I am very surprised that my soldering worked 😊

Which glitchwrks board did you purchase?  I've got two IPXes one of

which I had modified with a haywired 2032 holder but these boards would

be cleaner.

Anyone who read my posts about SSL might have seen that I was working

with a pair of Sparcstation IPXs.


I've had these for some time, carting them from place to place

frequently just using them as monitor risers on my desk. When I powered

them up recently, one of them had a very dead HDD, so I replaced it with

a SCSI2SD device, the other still has the original 400MB HDD.


Both had dead NVRAM batteries, so I picked up a pair of the

glitchwrks.com replacement battery packs, and just got around to fitting

the first one.


I reset the NVRAM, programmed an ID, and it booted.. LOL..
