Dear Klaus
I just soldered together the A2000 remake v6.2 I then added a R4.0 A2091. Alles gut. I then added a Rev 6 2630 and was greeted with what passes for Guru Meditation these days. HDD access was so garbled I never made it to workbench (I am using a Zulu
scsi HDD replacement so replacing the scrambled mess on DH0 was easy.)
I too became suspicious of an interaction between the cards and searched for them by model number plus 'crash' to immediately find your post. I could not find the HCT chips you used easily and used HC. I believe they are slightly faster but that both
are significantly slower than the original ALS part.
Replacing U605 did nothing but replacing the second ALS245 right next to it as well fixed my problems too. Hopefully it has not messed up the bus for other cards. Looking at the bandwidth of the HC though I cannot imagine how.
Thanks so much for sharing the details 20 years ago.
