A few questions about Cyberstorm MkI 040

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.
