Last summer I picked up a Tek 2230, a 100 MHz two-channel
digital storage oscilloscope.
I think I'd like to check it checked out by a repair
service to confirm whether all its functions are working or not.
Can anyone recommend a service for this? I don't need a
full NBS certification, just a check-out.

Doesn't the manual for the Tek 2230 cover calibration procedures? The
manual for my 531A provides step-by-step details on how to calibrate
it.

I've had my TEK 465 for over twenty years, yet it's never needed any sort of
adjustment. It's likely that solid-state equipment like this will stay in
adjustment for many years, unlike the preceeding generation of vaccuum tube
equipment, much more influenced by mechanical and particularly thermal
stresses.

A Tektronix service technician once advised me that unless I needed the NIST
Certification, the way to get my 'scope tuned up and adjusted not just to
within spec's but to the "best" adjustment possible, I should just have it
"cleaned." This gets the potentiometers and the various switches and
contacts cleaned and gets everything tweaked.

On top of a fairly high reserve too I'm sure. The present bid is by a guy at
Mac.com - may be an employee or someone that uses Apple's info service - but
otherwise someone involved the the Apple/mac world.
It doesn't even have a monitor and he wants that much to ship/pack? The bad
part is that he'll probably get what he wants though.

Bid is up to $250 with 2 days to go, is this a horse race or what?
Kind of makes me wonder what my "personal" buy/sell price might be. I know
I have at least a $50 itch for one, $100 much less so, but if I found one
what would it take to pry it away? I'm not sure I would be willing to sell
if I had a nice condition unit for even $250.

I've seen these things around, a local advertising firm had stacks of them
they were throwing away. These are basically Macintosh IIfx's clock chipped
from 40MHz to 50MHz, in a gigantic metal tower case
with power and frame key
locks. An interesting machine, but remember before
buying...
1 - The IIfx uses wacko 64-Bit (I think) SIMMs that aren't compatable with
anything except a particular LaserWriter. These are VERY hard to find and
expensive.
2 - The case weighs a TON. I'm not kidding, think double width MicroVAX II
tower case here, but with thicker sheet metal. Shipping will be very
expensive.
3 - It's still a 68030 processor. A slow Quadra (68040) can give it a run
for it's money.

In a way its sad, but the once "wicked fast" IIfx now is regularly scrapped
and the boards, memory, etc. sell fairly cheaply. I think I have about a
dozen working IIfx and a fair stash of memory (sheesh, NEVER in my life did
I think I would have this much memory (all sorts, but some IIfx), a pile
about 2 feet across on my dining room table).
The other stuff just makes me want one or two even more, just not to ship ;).

I picked up a IIfx and I'm pretty pleased with it. I spent a small
fortune about 2 years ago upgrading memory in it.
I'd love to see it run at 50 mhz... but it's a very sweet box.
Too bad I can only run Apple's A/UX or Mac OS 7.x.

No, System 6.0.8 works on it just fine. IMNSHO, A/UX or System 6.0.8
are the best OSes for it. System 7 is a fat bloated pig of an OS, and
the more recent MacOS releases are even worse.

Whereas System 6 is only marginally nicer than Atari TOS.
The IIfx is a quick machine, and has run System 7 quite fine whenever I've run
it.
System 6 may be a nicer alternative for low-memory 16-bit machines, but if
you've got a 32-bitter, it's not worth the sacrifice.

Gotta disagree with System 7 being a fat bloated pig of an OS. OTOH, 7.5
and on are. Because of this when I bought my PowerBook 520c new, it came
with 7.1 installed, and disk images for 7.5 on the HD. You could switch to
7.5 when you added RAM, or if you were really stupid you could try it in
4MB. The 16MB RAM upgrade cost $600! This was in '95.

I had two choices... System 7 - (7.6) or 7.0 and I went
with 7.6 for
the TCP/IP support.
TCP/IP may be installed on any System 7 version. Of course, back in the days,
one would have to buy MacTCP or System 7.5 in order to gain TCP/IP, but it
came along with my NIC install disks and works fine on System 7.0x or 7.1.

Ebay bid is back down to $41, some newbie retracted a $300 bid (which tells
us the other guy is one bid increment below $250).
I have one of the two IIfx speed toys I want, a Newer clock chipper, but I
still am looking for the Tokamac 68040 board. The CC is pretty good at
getting boards running as fast as they can, small software controlled speed
increments, with dynamic changes to stock speed for certain operations etc.
The *nix problem are the 6502 controlled serial ports, I think. How hard
could it be to write drivers or whatever to resolve the issue?

IIRC, A/UX has support for the IOPs. Other than that, the simplest thing
to do is put them in passthrough mode so that it acts like a normal Mac's
Z8530. There was a CDEV to do that for System 6.0.8 and probably 7.0.
It couldn't be too hard to disassemble it and figure out how it does
its magic.

I think the bigger problem is the SCSI access...
I think there's some IOP DMA issues.
The problem's not drivers -- just the total lack of documentation
on how the stuff works.
I don't think Apple's interested in putting the hardware info
and software info out on the net.
Unfortunately, not everything's as easy to get docs on as DEC gear.

Yes, $50 is quite a bit to pay for shipping, but in some cases, that's what
it costs! That unit looks big enough to cost that much, particularly if
it's being carefully and toroughtly packaged. It must be a pretty rare
unit, though.
I had to ship my Okidata Laser printer for repair a few years back, and it
went 3 times, at $53 each time. Now, it's a nice printer, but ... that was
supposed to be warranty service, after all ...

Why? I am guessing you will be out $50 to $100, and thats assuming its fine
and needs no "adjustment".
I would just use it, wouldn't most problems be fairly obvious?
