3000D SCSI issues
« on: February 08, 2010, 02:33:27 AM »
Okay, I got this old Mitsumi SCSI cdrom I tried to use with my 3000D. I plugged the CD rom in, put the centronics to 25-pin cable on the rear SCSI port, then booted it up. The HDD, the only internal device refused to boot. So, I removed the CD-rom and tried to boot the machine again, nothing... My SCSI cable has a terminator soldered onto the end of it. Now, I have reason to suspect it screwed something up. I have the prototype WD chip, buster rev7, dmac-02, I think those have everything to do with the SCSI. i even read the manual of the cd-rom, it apparently shipped with an 8bit ISA card and was for MS-DOS. The manual says nothing about SCSI or termination, merely talks about DMA and IRQ and stuff like that. That has led me to believe this is a parallel CD-rom, and it screwed something up. The computer now turns on and just sits there, I can't get to the early bootup screen (maybe because I rely on the AMBER?)

Need a part for a PC or Mac? PM me, I\'ll let you know if I come across it.

MorphOS, OS4 and Classic Amiga systems are the only ones who are real \'Amigas\', not that joke AROS or Amiga Forever.

Well i'm a moron for forgetting the SCSI ID and termination pack, Cause it's requiring all my strength not to bust the POS Mitsumi drive.

I repaired the track with some 22 gauge wire, i also took the opportunity to fix my 3640. So, now all i need is that diode, time to run up to RS. Anthony, you were right, the track was burned right up, so the PSU is okay. I'll see if I can't get her working again.
