Re: SPARCstation 20 with SCSI2SD

I'm not sure, I don't personally see it as something worthwhile to investigate when you can just rebuild the old NVRAMs. Even if you do use a SNAPHAT type replacement, you're still stuck with proprietary batteries that will one day no longer be made, versus an extremely common CR1225 cell. I've

Re: SPARCstation 20 with SCSI2SD

Also, to anyone buying NVRAMs on eBay, don't expect anything from China to actually be new NVRAMs. I've bought a bunch to disassemble, in the course Are any of the SMD NVRAMs with the battery caps compatible? Throw them on a DIP to SOIC PCB? - Ethan -- : Ethan

Re: SPARCstation 20 with SCSI2SD

They're still made, but the new ones don't always work in place of the old ones -- not 100% anyway. It's been my experience that, on sun4c and sun4m, new 48T02s and 48T08s aren't 100% compatible. I've mentioned others' suggestions on what the differences are in my Tindie listings, and on the

Re: SPARCstation 20 with SCSI2SD

I was hoping to just emulate it for now to avoid potentially bad hardware, but seems like I need to use the real hardware to avoid potentially bad software! :) Ah cool. I was at a friend's brother's house on a work trip out to Silicon Valley. One of his friends was there, with something

Re: SPARCstation 20 with SCSI2SD

Well, got the last problem solved rather quickly: I tried using 512 byte sectors for the emulated CDROM instead of SCSI2SD's default of 2048 for a CDROM, and that did the trick. Working my way through the SunOS 4.1.3 installation process now on the SS-20. Was just thinking the 512 byte thing

Emulated DEC Drives: UC07 and SCSI2SD

I am bringing up a MicroVax III in a BA23 box and I intend to run it from an SD card attached to a SCSI2SD adapter. The SD card was setup to have the size of RA90 and RA82 drives using the scsi2sd-util program on a Win7 computer to  partition the 4GB SD card . When I attached it to an Emulex
