Recapping was done professionally, so should not be that.
In any event, have managed to get around the Sad Mac issues by rejigging the order of the SCSI devices and cable combinations (Mac->iomega->ext Hdd->CD300e) and moved the active terminator (the short SCSI connector) to new end device. That seemed to make things work - go figure! (if you know why that makes a difference, let me know!)
That said, still no luck booting off that internal HDD so I bit the bullet and just reformatted the 40MB Quantum HDD and installed 7.5.3 over it. The install onto the 40MB actually failed right on the last disc/step for some reason, so either it's a SCSI issue, a power thing, else that drive decided to fail post recapping and hence was the issue all along. (That said 2 other drives I have, 1 a new refurb, all wouldn't come up either - suggesting internal issues).
Anyway, as it is, I just ended up swapping out my external HDD for a SCSI2SD 1.9GB drive and installed 7.5.3 on it without issue and my mac now boots 'fast' off the ext SCSI2SD (ID=1) and I scan see the 40MB drive (ID=0) too even though it won't boot!
Next step, I think I will probably swap this SCSI2SD and 40MB around - wondering if the AB or power supply is having issues with these mechanical drives (as I tried 2 which all failed to be properly recognised or boot from the internal spot) and might do better with the SCSI2SD internally (indeed I noticed the SCSI2SD seems to be able to power off the SCSI cable without power when it managed to boot up from the external Apple 80SC enclosure which was powered off!).
