Re: Some (Other) IIgs questions

[michaelmaginnis@yahoo.com (Michael Maginnis)]

Hi Bill,

Here's what I've tried:

1 - IIgs -> Zip (terminated here, no other devices on chain) : works
fine

2 - IIgs -> NEC 4x (terminated here, no other devices on chain) : does
not work

3 - IIgs -> Zip -> NEC 4x (terminated here) : Zip works, CD-ROM does
not

I'll have to get another cable to try the (IIgs -> NEC -> Zip) config.
 I may have to get it custom built; no one seems to carry the (narrow
50-pin <-> SCSI-1 25 pin) cables around here any more.

I also have an Apple CD150 drive, but I don't have a Centronics-style
terminator or cables for it, so I can't swap the CD-ROM drives.

Mike
