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)

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

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.

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

[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.
