On page 6 the "SA800/801 Diskette Storage Drive // OEM Manual", dated
May 1980, states the following differences between the different
models:
800-1 Soft Sectored with an FM (single density) data separator.
800-2 Soft Sectored without data separator.
800-4 Mechanics only (No PCB).
801 Hard-sectored with an FM (single density) data separator and
sector separator.
NOTE
To convert a 801 to a 800 move the shorting plug from the 801
position to the 800 position. A 800 cannot be converted to a 801.

My machines are in the same state, which is why I asked about the stand-alone
utilities. The only standard DEC card was the CPU. All of the rest was custom
to Tek. The version of the box with 5" winchester uses a sasi host adapter, so
in theory it should be possible to image the disc.
I am looking to replace a blown Zener diode for a Morrow s-100 mother board
called Wuderbuss with Noise Guard 1977 G. Morrow Thinker Toys. Any known
schematics?
Here is the problem:

...note the blown Zener Diode at the top of the picture. I am unsure of
the cause.
Thanks.

Hi folks,
Yesterday I picked up a Multitech Microprofessor II* plus some other goodies
like an EACA Video Genie and lots of useful Sinclair QL bits, only a 7.5
hour round trip too :)
On inspecting the MPF-II's box, I'm guessing it's been sat in a cupboard
since 1985 as a lot of the internal walls have reacted badly with the PVC
cables, some of them have been eaten through. What plastic can I wrap the
cables in to avoid any more damage? Polythene wrap?
Cheers,
*never seen one in the wild before, or even on auction sites.....IIRC it was
largely designed to be Apple ][ compatible.....

True, and sad.

Quickware and Strobe?

For those who remain unconvinced about the importance of ESD:
http://www.eetimes.com/news/latest/showArticle.jhtml?articleID=199203948
Disk drive heads and media are manufactured using Semiconductor lines, so
they have the same problems. Disk drives are worse in fact, since the heads
and media are exposed to air during manufacturing. I just saw a study that
found head failure to be the number one long term failure. The wear study
expected to find bad motor bearings or gasket break down. Instead, MR heads
are usually the first item to wear out by a big margin. The study separated
crashes from head degradation, so it truly is head wear out. Electronics
(PCB related) failures were under .5% of the total.

Well that seems a lot closer to the truth.

You can still buy licenses, and yes, I do know someone to talk to about
it.

I'm honestly not sure who might still be making hardware at this point,
although I don't think Mentec is any more.

You'd have to ask them about that one.

I've spotted this nice setup locally, wondering if the guy is asking
way too much for it:
http://chicago.craigslist.org/chc/sys/322279611.html
If the link goes dead, it's an IBM 5110 PC, 5103 Printer and 5114 dual
floppy unit.
Yeah, I know, it's worth what people will pay for it. But I don't
even see any completed on ePay, so I can't begin to gauge the
appropriate value. Those big floppy drives are calling me, though...

All,
About a month ago I picked a nice stash from a freecycler wishing to
clean out. The summary list: Partial Apple II, II+, IIe and lots of h/w
accessories and software. The fuller list is at the end of this entry.
I'm not a big collector (I have a Obtronix Apple Replica and Kim-1
(another 6502 SBC)). But I thought I'd piece together a nice
representative Apple 2 and sell off the rest. I haven't tested anything
yet.
Question 1: Which to keep: II, II+, or IIe? I need to review Apple
system hardware history, but I'd figure the IIe has the most
capability, but the II is more significant.
Question 2: Which accessories are significant to keep (you know, but
hate to say it: "VERY R at RE!!!")? Some
things may be rare, but I doubt I'd use them. For example, the Switch-A-Slot
(see http://tinyurl.com/2m8b3e )
Thanks for any helpful suggestions!
Scott
