There is the possibility that the 4 layer board was needed to reduce the effects of noise on the bus, but I think it's more likely that you are suffering from the same old SOTS (Slap On The Side) problems of the A1000 when trying to run more than one peripheral on the expansion bus. Have you done the PAL grounding mod? If not, it's worth doing. -larry -- Entomology bugs me. +-----------------------------------------------------------------------+ | // Larry Phillips | | \X/ lphillips@lpami.wimsey.bc.ca -or- uunet!van-bc!lpami!lphillips | | COMPUSERVE: 76703,4322 -or- 76703.4322@compuserve.com | +-----------------------------------------------------------------------+

[Hallo the line eater!] I need some help with the C Ltd. A1000 SCSI Interface. I bought the above interface with a C Ltd. Hard Disk, second hand, intending to use both on my A1000 with a MAST 2Mb MiniMegs. The MAST memory module doesn't have a pass through connector (el cheapo) but the SCSI interface was supposed to, and I didn't think to examine it too closely until after getting it. The pass-through connector on the SCSI interface is female, meaning that I cannot connect the memory board (also female connector) to the expansion bus through the SCSI interface. The C Ltd. manual states that the company would provide the correct connector for $20.00. I've called around, but no dealers seem to still have this part in stock. I tried to fix up a straight pass-thru male-to-male connector, but this results in random gurus. I would like help from someone who still has a C Ltd. SCSI interface AND has received this connector thingy from C Ltd. Could you tell me what connections are being made? (ie: All pins connected straight thru? or are there shorts and/or unconnected pins?) Even better . . . would someone like to sell me this connector? (Make a profit on your $20!) The RAM board and the SCSI interface work fine individually. Does anyone know if the power supply on the A1000 can support 16 1Mbit simms as well as a SCSI connector? Maybe my problem is not enough power. Thanks a lot for any help. - Harshy. ------------------------------------------------------------------------------- hdw@cunixd.cc.columbia.edu ...rutgers!
