i didn't think there was a cyberstorm mark1 040.

there was a cyberstorm mark2 040, and that could be modified to take an 060, but the 040 is a 5volt chip and the 060 is a 3.3volt chip, so you will have to find out what jumpers you need to solder, and if you need any extra resistors and capacitors to complete the 5volt to 3.3volt voltage regulator... plus change the oscillator too...

if you just drop an 060 in an 040 socket, it'll just burn out.

as far as i know, amigakit do referbished scsi modules for the cyberstorm mark2.
 :-)

if it is a fully working mark2 040, and you don't do the 060 upgrade, for 60euro it is worth every penny/cent  :-D

The MKI isn`t that easy upgradeable as the MKII / MKIII or much easyer to Upgrade, depending on the point of view.
For an 040->060 Upgrade you need a 060 MKI CPU-Module (the whole thing) and a ROM that holds the 68060 initialisationcode that goes into the socket on the carryerboard. So doing the upgrade is easy, but getting the parts is nearly impossible.

The SCSI-Module for the MKI is harder to find then that for the MKII, therefore it will cost you more. I have seen some go for about 100 EUR.

Anyway 60 EUR is an absolute bargain if it is in working condition. You can`t loose as you will always get that money back if you decide you don`t want the card after all.

Can`t say that for sure, as I only once had an 060 MKI.
Anyway from what is written in the BBoAH you`ll have to change the A4000 mobo Jumpers from INT to EXT (only 040@25 MHz hast INT setting just like the A3640, that way the mobo is clocked by the MKI crystal). If you rise the clock to 33 or 40 MHz and leave it to INT you will surely fry your motherboard.
No clue what else needs to be changed.

hmmm, i've left the jumpers set to INT by accident with a cyberstorm mk2. all that happened was the machine wouldn't even fire up. not sure about frying mainboards  :-)

looking at the connector for the scsi on the mk1, to the mk2, they look the same.... but that means diddly in electronics  :lol:

anyway, i doff my cap to you kind sir, for enlightening me to the existance of the cyberstorm mk1 040  :-)

btw, with an 040, it is usually just a case of dropping in faster oscillators... i cranked a warpengine040 from 28 to 40Mhz just fine. but with a dirty great big heatsink, thermal transfer paste, and fan.  :crazy:
