Free to a good home.
I have some vintage Sun4 equipment that I would like to give away to
someone who can use it.
The equipment is all located near Vancouver Canada. I will not ship it,
you will have to pick it up. I will help you load it.
Sun 4/280 in cabinet with 9 track 1600/6250 bpi 1/2 inch tape drive, two
Hitachi 900 MB SMD disk drives and 16 channel serial port.
Sun Sparc 1 pizza box computer, with 425 MB disk drive
Two Sun monitors
Sun 4/280 chassis with CPU, memory, disk controller and one Hitachi 900
MB disk drive.
Assorted Sun VME boards and extra cables and stuff,(disk controller,
SCSI interface etc.)
All the computers are currently working and running Sun/OS 4.1.3.

Dear friends,
Maybe someone with a spare Amiga 2000 SCSI controller/memory expansion,
or better, a GVT one is willing to make a brazilian happy, or sell for a
nice price? :o)
Just made an amiga happy again, and I'd love to use it. But without HD
and memory it gets boring...
Part of the recovering here:

If you're not opposed to putting new hardware into the Amiga (as
opposed to keeping it "period-authentic") there are people working on
expansions for the 1000, 500 etc that work in the 2000:

Those are neat. It's good to see some new expansion options. My
A1000 is loaded with tons of 41256 chips, bought back when they cost
between $3.50 and $17.50 *each*, but trying to find those old
expansion boards is harder than finding an A1000 in the first place.
The IDE and CF interfaces are a really nice touch. I think most
A2000s ended up with hard disks (even if early adopters bought them
without), but lots of A1000s and A500s were floppy-only.

Heh, did you do the "piggybacking" too? :-) I recently took photos of
my ugly hack to expand the 1000 with 512k "slow" ram:
http://signalsprocessed.blogspot.com/2011/06/ancient-history-my-first-amiga…
This was done in the early 90s, forgive my horrible kluging. I wish I
could find the instructions that I built this hack from - a quick
search of aminet and the Fish index didn't show anything, I must have
gotten the instructions of a BBS at some point.

I just recently found AmiBay and am amazed at the stuff people are
building. I'm counting my pennies, one of those IDE/Ram interfaces
would definitely be a nice thing...

I just paid about $5.65 shipped for *each* of my (16) 1Mx4-bit DIPs. I
was honestly happy to find them at that price. Those chips are
exceedingly rare and this is the first time I've found any for sale at a
reasonable price and quantity for the last five years. (and I've been
looking)
This was to expand a Microbotics VXL*30 RAM-32, from 2mb to 8mb, which
is an accelerator/ram expansion device for the A500.
The 41256 are much more common and available in comparison.

They are not SO rare in Brazil. Although uncommon, these can still be
found as pulls.

I'd adapt some 30-pin SIMMs on that...

And now I remember I need to build a ram tester, my new EPROM burner
doesn't tests RAMs :(

Indeed. I have tubes of them. They are cheap and available now, but
in 1986-1987 (when PCs had DIP sockets not SIMM sockets), the demand
was higher than the supply.

Political correctness is a doctrine, fostered by a delusional, illogical

LTAC (the user @ amibay selling them) is selling them for 17 EUR per
four chips.
I thought the price a little high, but I really haven't seen an
alternative. And was just honestly glad they were available.
My transaction was smooth, good communication, etc.

The 1mx4 chip was a 514400. (or 814400, 71C4400, 4C4001, 44400)
Isn't 411000 (or 511000) 1M x 1 anyways? How would that work if we need
4-bits wide (truly, 32 or 64 bits wide in total)
Someone went so far as to make small adapter boards(SMT->DIP) to take
surface mount 1mx4's, which are more available. I thought about these,
but they are kinda expensive for what they are (probably same price as I
found the right chips for) and involved 640 solder joints for the project.

If I teach you to use a 30-pin simm in place of a pair of 411000 it
would be useable to you?

You can do that boards at home :)

I have considered that path as well for my Rejuvenator, a more
reasonable prospect since there are only 4 chips involved (1M x 16
total), but for the cost of the small boards, I never pursed it
further.
At least it's only about 80 joints.

I'll look for some schematics of it, maybe a 4 x 32 72-pin SIMM can be
used, AFAIK there are 4 separate CAS lines
Or, if it is 16 bit, you can use the same 72 pin simm in half :)

I don't care much about age, but as always, I'm (really) short on money.
Euro60 for a board with almost no parts is too much to me :)
