Yes.
The better option is to repair the NVRAM to use a replaceable battery.
As noted elsewhere, the new ones on Mouser aren't completely compatible,
but they work good enough in my experience with the lunchbox systems and
SS5/20s.
- SPARCstation 1. Chassis is intact. It has a bad
IDPROM; aside from that
it passes onboard diagnostics. It has 12M memory, no HDD now, and a 3.5"
floppy drive. It has no SBus cards. Aside from the IDPROM, it doesn't
have any issues (but I haven't run an OS on it yet). Like the SS2, it
needs a bath. A small portion of the plastic cover over the rear of the
case is broken off.
What are these "actual parts expenses"? IDPROMs are around $25 on Mouser.
SCSI HDDs start around $70 shipped on eBay and SCSI2SD are $60 plus
shipping to me plus the SD price. Given the price of 25 year old HDDs with
a stated service life of 5 years (according to one spec sheet that I read),
SCSI2SD looks pretty attractive.
When you say IDPROM, is that a Dallas built-in battery NVRAM type of
thing? I have an SS1 with a dead NVRAM thing. Are the currently
available versions of those new at Mouser fully compatible? Those are
one of those things that the new versions aren't always fully
compatible with the old versions for some systems, even though they
are supposed to be.
My SS1 is also in the Seattle area. If there is much demand for those
it's probably one of those systems I'll never get around to doing
anything with it myself. I also have a 4/110. Those seem to be a lot
less common, and maybe more collectible.
I don't think there is much demand. The SS5s and 20s that I got from
Pete's place were claimed quickly. No takers yet for the SS1 or SS2. If
there ends up being no takers, I will still refurb them and make them
into nice running systems.
