This is a support page for all those owners of Amiga 4000Ts with Quikpak 68060
accelerators installed. Since purchasing my board I have had some problems
and questions. Others out there may be in the same boat. If you are, I hope this
page will be able to answer some of your questions. For those of you who do not
own the 68060 accelerator, you may find this page useful as well. Through some
investigation I have found out that the 68060.library was licensed from Ralph
Babel, and the 68060 board design from Jeff Boyer (Boyer Inc.) Some of you may
know Ralph Babel's name from his work on several Amiga Books and also the GURU
ROM for GVP scsi controllers. I am not sure
of the exact relationship of the license, but it seems that only the
68060.library and 68040.library stub were licensed. The CPU060 command is not
Ralph's work. Also, Quikpak (or perhaps Jeff Boyer) did not license Ralph's new
math library, that would work in similar fashion to phase 5's CyberPatcher
utility. I would encourage all of you our there to E-mail Quikpak and ask if
they will license Ralph's math library for their 68060 products. Also please
contact me if you have any further information about the Quikpak 68060 card.
Please keep checking back to this page in the never several weeks and days. I
will add performance benchmarks and other information.
Please note that this page has no affiliation with
Quikpak, phase 5, Boyer Inc, or any contract developers
that may work for those companies.
Software Support
Here is what I have determined to be the latest version of the support
software for the Quikpak 68060 accelerator:
| Software/Disk |
Current Version |
| Install Disk |
1.0 Download lha or
dms version |
| 68060.library |
2.2 (July 26, 1996) |
| Manual |
Download |
Recently it
has come to my attention that a different version of the 68060.library has been
shipping with the quikpak A4060T systems. This version is the one from
Coenobium
Developments. It is unknown why the change was made (perhaps it was a
mistake?). So far attempts to contact Quikpak have failed, but we will try
to get to the bottom of the situation...
New: Installation disks for 68060 cards can be downloaded from
Gregory Donnor's page.
Hardware Support
The
Quikpak 4000T
68060 accelerator runs at 56.75Mhz and will support EDO ram. If you can get
your hands on EDO ram I would recommend it. I have tested the board with and
without EDO ram installed. EDO ram gives an astonishing 15 to 18% speed increase
in memory access. With EDO ram installed the board is close to 2x as fast as
phase 5's Cyberstorm MK-II 68060 card!
Quikpak
also offers a desktop model of
the 68060 card. The desktop model sports a scsi-ii fast controller as standard
equipment! Please click
here for
more information. Please note that as of August 26,1997, there has been no
desktop model produced by Quikpak!
Problems
| Problem Description |
Solution/Comments |
| When using Shapeshifter and the serial port with TCP/IP the hard disk
locks up and the light stays on freezing the machine. |
Make sure your SCSI devices are properly connected and terminated. If
the problem still persists, try turning off scsi fast bus or synchronous
mode. If that does not solve the problem it may be a 68060 related problem
or timing/DMA issues.
Partial Solution: Run Shapeshifter off the IDE controller of the
A4000T. There seems to be some problem with the SCSI controller. I am
still getting some lockups on ShapeShifter. It seems that I can not find a
100% stable solution. |
| Prepareemul does not work |
Use the prepareemul A1200 switch |
| Rendering is slower on my 68060 than on my friend's phase 5
accelerator |
Non-phase 5 68060 cards do not include a Cyberpatcher utility. This
fpu patching is required because some instructions are missing from the
68060's fpu. Oyxron, a demo/coding group, is releasing a commercial
product named OYXpatcher that will work on all 68060 cards. For more
information go to their page by clicking
here. |
| The V-lab Y/C framegrabber card (from Macrosystems) when used with the
QuikPak
060 board does not always grab a complete video frame, instead only
grabs one field and keeps previous 2nd field in its buffer, thereby
interleaving two different images. Curiously, when we switch back to the
original 68040.library (thus slowing the machine way down), we don't have
a problem with V-lab. For more information contact Bob Richardson |
No solution yet. |
| Some Fujitsu hard drives do not seem to work with teh A4000T. (Note:
this is probably a general A4000T problem) |
I have tested both 1.0 and 1.3 gig Fujitsu hard disks on the
A4000T. Both were not recognized properly (or not at all) by the
Amiga. Keep this in mind when shopping for an IDE drive for your
A4000T. |
| FUSION is generally unstable and does not work (freezes after awhile)
when dialing out to an internet connection. |
This general problem with Mac Emulation and the Quikpak 060 hardware
is still unresolved. We are attempting to find a
solution. |

the EDO ram has a significant impact on both the read and write speeds of Fast
ram, with an upto 18.9% performance boost over FPM (fast page mode) ram.
