Why did DEC not use the LINCtape format for the PDP-8? I assume maintaining

My first inclination was to try the XOR approach, as that was most

Well, maybe that'll turn up if CROMIS doesn't.

Does anyone have any software for developing for the Intel 3000 series? I
bought some parts on eBay and am contemplating a bit-slice PDP-8 or DG Nova
for fun.
Bitsavers has some 3000 series manuals, but I can't seem to find any "bits"
of software. Looks like CROMIS is the cross microprogram assemb
Has anyone made a GDB front-end for SimH? Just curious. Seems like it could
be an interesting way to tie an IDE to SimH, if one were inclined.

The size is just large enough to fit in a 19" rack. It's also possible that
I don't have what it goes to.
Here are more panels to puzzle over:

I feel like I should know what this panel goes to...I found it in my garage

Anyone knows what these go to?

Thank you for the compliments! I'm looking forward to getting it going.
Any idea what the model (FIO) indicates?
Trying to locate some repair manuals and tips. Anything else I should look
for other than what's on Bitsavers?
The unit powers up and types with a few keys slow to act or return.

I ended up going with PakMail and was not disappointed. It arrived safe and
sound yesterday, and though the cost of shipping was almost as much as the
unit itself, I felt much better about paying a little more to make sure it
arrived without damage.

So, B-Cache is a common failure; any idea what specifically is failing
about it?
I've got a 1000A, but its been years since I've tried booting it. It was
successfully booting when I last tried it, however. I think I've got Tru64
installation media somewhere around here, too...

Several people have now mentioned they have dead Alphas. What is generally
failing about them?

I'm not able to load Living Computer's website. Anyone else?

The more quotes I get regarding shipping, the more I'm thinking to just
drive the 1300 miles (one way) and pick it up myself. I'd rather nothing
bad happen to it, as insurance money can't replace the unit (easily).
Any recommendations on finding a private carrier? It's in Colorado.
Kyle
Does anyone have any tips on preparing a Flexowriter for shipping? Any
thoughts as to crate vs. pallet?
Thanks,
Kyle
