Does anyone know of anyone who has done something similar to a IIci?  Does
anyone know if it is possible to do this successfully to a IIci?  My main
concern would be if the cache card would still function correctly (or even be
useful?)  Also, how bad would it screw up the video timing, or would it?


Thanks,

MicroTech sells a kit to convert the drive for use as an external drive.
Think that the prices is around $100.

Subject:    acceleration of Rockets

Hi netters!

I want to buy a Radius Rocket acceleration card for my Mac II but
I'm still moot if I should buy the 25 Mhz or the 33 Mhz card.

My intention is to speed up the 68040 by replacing the quartz setting
the clockspeed. Now I would like to know if there is another
difference but simply the clockspeed. If not, I could speed the
25 Mhz-board by myself.

An other possibility is to use an icecap which cools down the CPU
to 80 degreees F. The icecap should increase the processors lifetime
at the one hand and on the other hand his errors should be reduced.
So my thoughts were to speed a 25 Mhz-board up to 40 Mhz (it's
recommended to increase clockspeed by 25 % only). This was the most
important part of my questioning.

Now here comes part two. I own an old Mac Ii. If I have the old ROMs
(Rev. A) Apple should exchange them for the Rev. B ROMs for free, right?

Would I also need a PMMU?

My two Megs of RAm on board should be enough to drive the Rocket???
Of course I will buy more RAM anyway which can be installed on the
Rocket board itself.

Any answers are appreciated. Maybe I will contact Radius or Motorola
if someone could send me the phonenumber and/or the address.

Thanks in advance.

I fixed a similar problem with my Mac Plus.

Larry Pina's "The Dead Mac Scrolls" suggested checking or replacing a  
transistor in the video circutry.  The transistor was covered with a thick  
layer of glue, but when I cut the glue away the transistor practically fell out  
of the board!  I resoldered the transistor and haven't had any problems since.

I don't think you need the book.  Just examine your analog board.  You may have  
to look very closely to spot cold solder joints on your analog board.  But be  
careful!  You can die if you touch the wrong thing.

My Mac Plus screen has lost about an inch (diagonal measure) of screen due

anyone on the net has done this, and whether it is relatively easy to do.

I have been experiencing this problem for about a year and a half now and
haven't had major problems with anything. Every now and then, I get
ambitious and talk to repair shops about the problem. Usually, they try to
sell me a power supply replacement, so I figure that until a total failure
happens, I'll just keep hitting the side of the monitor (which usually
restabilizes the picture). If there are any other repair fanatics out
there, I welcome your suggestions.

   You can use one of several INITs, or you can add a keyboard map to your

   available from ftp.apple.com in /pub/powerbook.

Unfortunately, it seems that the caps lock disabling init crashes when

	Maybe, but I think it's well known that (and I guess I'm saying this
in case it's not) the IIsi 8-bit speed penalty can be "won back" by setting
the RAM cache to 384k (or whatever it is).  No more speed penalty for 8 bit
color!

We have a LocaTalk network which includes several PCs equiped with
LocalTalk cards. In the near future we wish to connect the LocalTalk to
an ethernet network (probably using an EtherRoute box).
I am told that the Macs will need MacTCP software but is there software
that the PCs can use to enable them to access the ethernet via the
existing LocalTalk network? We don't want to have to run ethernet in
parallel with the LocalTalk.

Thanks,

We have an SE 30 that doesn't get used as much as it should mostly 
because of the small display. Problem is, we don't want to give up the 
Ethernet connection in order to buy a large screen monitor. I was 
wondering if anyone out there has had experience with ethernet cards and 
large screen monitors for an SE 30. I called asante and they make a card 
(MacCon + 30EIR) that supports the Radius Pivot. I couldn't get a
straight 
answer out of them as to whether it supports the  new Radius Pivot LE.
So, 
I was wondering:
1. Has anyone used the aboe Asante card with a Radius Pivot Display 
(especially the LE)? Is it a good combination?
2. Is there another card which supports and external large screen monitor?
3. Even better, is there a monitor card that will allow us to keep our 
current Ethernet card (Kinetics/Novel/Shiva card).
Thanks in advance.

The choices are the older 24-bit addressing or the newer 32-bit
addressing.  Have you ever figured out what 2^24 is?  It's about 16
million.  Now, if you have 20 million bytes of memory and can address
only 16 million of them, there is going to be some problems
introduced.

Since the Mac can't address more than 8MB of RAM in 24-bit mode (the
other 8MB of address space is used for I/O devices and ROM), the
unusable RAM is attributed to system usage in the "about" dialog.
With 32-bit addressing the limitation is removed and the processor can
address 4GB of memory.

Well, today I got a note from Steve Strange saying that he had performed an
upgrade on his SI. The strange (;) thing is he couldnt find a 50Mhz crystal
and so used a 44.4444. Hmmm, not sure id do it unless i could find 50Mhz...
The interesting thing is that he reports nor problems with the FPU. anyways,

Mark,
 
I'm not able to post to the net for some reason.  Feel free to post
this if you like:
 
I did the upgrade the other night, and I have a co-processor.  I
couldn't find a 50 Mhz crystal though (called all over the place), but I
scrounged a 44.4444 Mhz one, and it worked fine.  Only an 11% CPU
speed improvement, but I got about 25% improvement in 8-bit color
display.  The math CPU ran fine -- FP benchmarks were about 11% faster
as I would expect.  So I guess I have a unique IIsi, '030 running at
22.2222Mhz.  :-)  If I find a 50 Mhz crystal and a socket, I'll
probably try that.
 
BTW, it looks like the 8-bit display mode is right on a steep curve of
display performance vs. CPU speed.  1, 2, and 4-bit run about the same
on the regular IIsi, but 8-bit is about half as fast.  This ratio
changes when you go beyond 20 Mhz, to more like three-quarters for
25Mhz and a little less for 22Mhz.  So bringing the IIsi down to 20Mhz
really hurt 8-bit performance as compared to the IIci.  I wonder if
Apple knew this was the case?

  1) No you cannot connect an external moniter to a generic 145.  You will

  2) Yes you can connect a Duo to a small dock which allows 8 bit video
