Organization: University Of Alberta, Edmonton Canada
Date: Wed, 18 Nov 1992 00:36:18 GMT

I have a couple of questions regarding a flicker fixer for an A500:

1.  I have heard conflicting reports about the ability of a flicker
fixer to fit in an A500 case with a CSA MMR accelerator.  I am
interested in hearing from people who either have both co-existing in
their 500 (with no problems), or from those who know for a fact that
they cannot fit together.  (I have a 32 bit daughterboard as well with
the MMR that may get in the way...)  So if you know of a flicker fixer
that either does or does not fit with the MMR, please send me the name
of the flicker fixer.  I'd like both a flicker fixer and my 68030, but
if I had to make a choice, the 68030 would definitely stay! :-)

2.  If the flicker fixer does fit in the A500 with an MMR, does the
standard A500 power supply have enough juice to power everything?

3.  I'm a bit confused about what the flicker fixer does with various
monitor refresh rates.... Would a flicker fixer work fine with my
existing 1084 monitor?

If you can offer insight into any of these questions, I'd love to hear
from you.  Thanks a lot!   Dan

First, BEG, BORROW, STEAL or BUY (I would suggest the last opition, buy) a copy
of Quarter Back Tools. This program will solve your problem. I had the same

I think you have got your figures wrong. In the Uk the A4000 sells for 2100
pounds at the cheapest with 120meg drive and 6megs ram. A 1960 is not included
it would cost you another 400 pounds taking the total cost to over 2500 pounds
over 1000pounds more than the 1200 set up. The difference being that you have a
25mhz 68040 and expandability :-)

Not in my, admittedly limited, experience!
I added a Maxtor LXT-213 to my old Quantum P105S (the 5.25
half-height older generation). In spite of specs that said the
newer Maxtor should be faster, it is in fact noticably slower.

Since your A3000 has an SCSI harddisk. (Most possible Quantum) and the
A4000 has an IDE (Seagate) drive. I get the same phenomena with the IDE
drive in my 386...

It is possible, my A530 runs like a dream with a real '030.
You just replace the 'EC030 with a 40 mhz '030, and then you can
run _the_enforcer_ and other MMU toys. You don't have to change
any jumper-settings or anything of that kind.

Quarterback Tools will fix your HD problems, it has rescued my drive more than
once from the same problems you have.  It will also do a bunch of other things 
to keep your hard drives and floppy disks healthy.  There are other utilities 
commercial and PD that will also work but I know and use QB Tools.

  My first foray into the laptop group here at work produced the correct
cable for my "soon to be here A1200".  It was, however, a foot long...
On my second trip I came up with one that is only 1.5" long.  Hopefully
that will work nicely.  Anyway, one of my cables had connectors with the
3M marking on it, so the connectors must be sold in the US by 3M.  I
would suspect that Amp carries them as well. 

  Good luck in finding a cable.  It was rather dicey finding one here at
work and we make laptops that use these drives (most of our designs use
the flex circuit as well).  This is definatly not an item you will find
at your local Radio Shack.

80 megs would be nice, but probably not cost effective.  And listen up C=, we
mean business!  We aren't going to but 1200s w/o hard drives!  (I'm not, and
I'm sure most others with 500s and hard drives won't either...  I for one 
refuse to step down from a hard drive + 5 megs to 2 megs + one floppy!)

Of course, if there's a 3rd party willing to put them in cheaper ... we might
reconsider. :)

Yes, you must name the 1.3 system disk, WB_1.3, at least with the
version I have.  Futhermore, it must be at SCSI address 6 in order for
1.3 to recognize other partitions (like Work:).... I find this
irritating, but liveable.

I do it all the time.  My WB_1.3 partition does not mount when I boot
2.04, but if I change the name of the partition to WB1.3 (no underbar)
wb2.04 will mount the 1.3 partition when I reboot (no data loss). 
Then I can backup ALL my partitions, including 1.3, on one tape and
then I change the name of the WB1.3 partition back to WB_1.3 via
HDToolbox again, to return to normal operations.  Have not lost any
data yet...

Agree, It's probably why C= didn't made the A4000 with 30KHz + rates on all

Heh, I can't give you a magic formula or anything, but I have seen EDAC
in action, and it works.  A bit of military equipment I worked (and later
taught) on utilized an EDAC scheme to ensure data security.  We had a BLAST
trying to explain it in class, as the few documents we had only explained
the concept, not the mechanism.

Basically, out of a 30-bit word (don't ask me why 30?), 6 bits were EDAC
or "hamming" bits while the other 24 were useful data.  The EDAC bits were
really glorified parity bits, set or cleared based on ODD parity.  Each
EDAC bit was assigned a group of data bits that it covered.  The first 3
were simple:

The high EDAC bit, or overall parity bit, indicated the parity status of
all data AND the other five EDAC bits.

The next covered odd-numbered bits, the next even numbered.  The other 3
covered groupings that were not so clearly defined.

On decoding, the mechanism on the other end understood the "rules" in which
the original was encoded and could determine, based on how each EDAC bit was
set, the state of the received data:

0	No error
1	Single bit error detected and corrected (or just labeled depending on
	how the equipment was configured).
2	Higher number of parity errors detected, no attempt to correct.
3	Overall parity error (high EDAC bit).

We had to make do with a chart showing the groupings of the EDAC coverage...
and in one class at least we spent an afternoon "simulating" errors and
attempting to "break" the decoding scheme.  It works, but don't ask me how...
I don't think that part was declassified, anyway :-/

I heard from a friend that an ad in some U.K magazine advertised a 4Mb

Does anyone out there have a MicroNet Removeable Hard Disk Cartridge Drive
connected to an Amiga 2000?  It is an 88MB with SyQuest Mechanism..
It seems to work fine other than the fact it has some kind of power feedback
going to the A2000, leaving the power light on but dimmed when I have the A2000
turned off and the MicroNet on.

Does anyone have any software specifically for use with SyQuest type drives, in
which I can eject the cartridge like on MACs?

Where can I get good inexpensive 88MB carts.?

I also used a 44MB SyDOS drive and it did the same thing, could it cause any
type of damage?  Does anything have to be modified for use on the Amiga?  It is
actually for MAC systems..

You can't. DRDY is generated automatically when you write to the port. (See
the timing diagram). You can't poll ACK directly, but a negative transition
will set the FLAG bit (which can cause an interrupt or may be polled). This
is very clearly described in the "Handshaking" paragraph.

Just a note here:  When posting or distributing AIBB modules, it is important
to also post the version of AIBB used to make the module.  Modules are
not necessarily compatible from one version to the next (and incompatible
modules will not be loaded by AIBB).  This is because as test code/results
change, it is necessary to update the module format and setup.  As of
AIBB v5.5 (due in a few weeks or so), which will have a new module format,
every effort will be made to maintain that module format so such 
incompatibilies will not be evident.

A patch also just went through SAN/ADS.   Don't know what it does, but its
there.  Called 4091 or something like that.
