Installed my 68060

[Doppie1200]

Hi all,

I just installed my 68060 and I'm impressed with the speed gain over a 68030. Since the A1200 I installed it in is not towerized and is thus relying on its chipset for everything, I did not think such an improvement was possible. Everything is even more responsive than it already was.

Anyway, I thought I should check if you guys think the same about this problem I'm having.

The diskdrive seems to go berserk after awhile. The nice clicking turns into grinding noise. It seems the steppermotor is out of control. A diskicon appears as if a bad disk is inserted. No disk is inserted at all when this happens.

A reboot does not fix it but influences the behaviour. The stepper motor could stop doing it's weirdo thing and the diskdrive LED stays on.

Anyway I put my 030 back in and now the drive works agian. If it starts acting up with the 030 in place I'll keep you posted but this is my initial diagnose; Bustiming faults.

I need my board patched  :-(

EDIT: typo in the titles (oops)

Which 060 board do you have? An Apollo 060 needs Oxyron Patcher to speed up some functions like FPU calculations.

Don't forget to install the 060 libraries, They can be found on the Aminet site. If you have a Blizzard install the 060 disk on your HD.

What is the revision of your mainboard? And what kind of PSU do you use?

I have an Escom A1200 revision 1D4, DCE Blizzard 1260, SCSI kit, 2x64 MB of RAM, notebook harddisk 1 GB, a power computing HD diskdrive connected to an A500 4.5A PSU.

Sometimes I have crashes, I thing I have a PSU problem. If I disconnected the diskdrive I don't have crashes.

Your problem with your diskdrive can maybe caused by a broken 060 :-?

[Doppie1200]

Hi,

No I think the 060 is fine. I have a very yellow A1200 as spare and that one does not seem to have the problem.
Allthough I have not done very extensive testing yet.

If the other amiga has no problems I'm thinking about swapping the internals of the two.

It is an Apollo 060. I could not find a blizzard. I prefer the blizzard.

The mainboard of the amiga is 1D4 and so is the one in the spare 1200. The PSU is a beefy A500 one. That means it can deliver currents up to 4.5amps on the 5Volts line. Seems pretty simular to your setup. The harddisk is also notebook (4G) And I have only one simm installed (32M'). The SCSI module is not yet installed (one step at a time) Could still be a power problem I'll have to look into that.

Edit: O I forgot to mention I have used the default libs that came with the card. Going to try MuRedox later. Don't have a copy of cyber or oxy-patcher and I hear MuRedox is good too. (maybe I have that name wrong)

Ok forget this thread. The diskdrive went nuts while the 030 was installed. Guess something is wrong with either the diskdrive or the motherboard. Time for some hardware fiddling.

thanks anyhow

Just to let you know... an A500 PSU will probably not do it and thus it can be power problems. When I had my A1200 hooked up to an A500 PSU with B1260, 2.5"HD and external diskdrive the PSU had to be turned on, off and on fast again just to get the {bleep} to power on, without external diskdrive this wasnt the case and if I installed the PCMCIA ethernet card it wouldn't boot at all no matter what (can't remember if I had the internal scandouble installed at that time though). The A500 PSU is more powerfull yes, but only to some extent... I ended up using a 200W AT PSU with the mashine and now it work perfectly even with SCSIkitIV, internal soundcard and iocard (no scandoubler though, it's in my A4000 now). :-D

[Doppie1200]

Thanks. I'll keep that in mind (while looking for an AT powersupply (wonder where I'm going to find one of those these days.

Meanwhile I swapped the motherboard with another spare one. I had a rev 1d1 laying around which seemed in better shape than the one in my spare amiga. I mistakenly assumed the spare amiga had an 1d4 but it has a rev 2a. However the board is in not such a good shape. The tinware looks like it was in a car accident and even the onboard 28Mhz crystal is dented.

Got the 1D1 running now and having my 030 archiving my entire (whopping 30Megs) Sys partition.
If all still works when it's done I'll install the 060 and have that backup my games partition (undisclosed size).

thanks again.

Get an ATX then. In order to get it to power on you just need to put a switch in between two wires.

[Doppie1200]

Only a switch? Maybe I can create an autoshutdown somehow. I don't use the uart very often.

Hi congratts with your 060 you will love the speed i could not belive the speed difference when i got mine over the 1230Blizz hope you get your diskdrive stable period.

The atx conversion is dead easy. tell me if you need pics to do the job i will email them to you..


adonay :-D

[Framiga]

when you swap the 2 mobos, you are still using the same HD flatcable, or 2 different one?

[Doppie1200]

Still the same cable. why?

I will look into this atx convesion thing. Thanks alot, if I need pictures I'll drop a PM. Good to know modern hardware is still usefull for the old miggy.

The machine is stable using the 1D1 motherboard. Currently doing benchmarks on 3 different boards I have.

Stock CPU + 4M *0 waitstates* fastram
030@50 + 32M
060@50 + 32M

Suprisingly it seems the stock CPU is fastest when it comes to accessing chipram. I wonder why.

[graffias79]

Hmm I had one of those old 68030 accelerators (Jetfire 030), and now with my Blizzard 1260 I was getting the same strange FDD problem.. click click click grrrrrrrrrrrrrrrrrrrrrr DF0:? *poof*...  click click click grrrr.....  I usually put a disk in to shut it up.  But it happened on 2 different motherboards and 2 different accelerators.  Of course now it isnt working very well at all, as you can see from my other thread.  I may switch back to the 1D1 board to see if I still get the same effect.  (currently 1D4).

(I'm glad I read my previews, because I misspelled disk.. with a c) lol

[melott]

Don't you guys use 'NonClick' ??
I've used it for years, since way back when I
ran a BBS on my A500. I've NEVER had a problem
with floppy drives.
I hate hearing that clicking sound, I think it
wears out the drive much faster.
NonClick works great (available on Aminet), it
just takes about 2 seconds longer for the drive
to reconize a disk has ben inserted.
I HIGHLY recomend it.
