Hello all,
I'm new on this forum. I did a search on my subject but got no match.
Here is my problem: I am in the process of restoring an Amstrad PC 1512 (XT class, 8086 at 10 MHz). I've managed to install an ST-225 20MB drive salvaged from a no more working IBM, re-low-level formated it (it was a long time I hadn't used Debug...) and found images of the original install disks. I've managed to copy these images to the hard disk (by shutting off the IDE controler of an old Pentium PC and stuck the MFM controler in the ISA bus - to my amazement it did work!
Now, to ease data transfer, I'd like to convert the pentium (it's a Packard Bell) to a machine with hard disc, DVD ROM, 3.5 and 5.25 floppy. And there is the problem: I have a cable that has three connectors: from the motherboard connector you get: a 3.5" connector, a 5.25 connector, then the twisted cable and another 3.5" connector.
I don't manager to get both drives working: I set the 3.5 as A: (1.44MB) and the 5.25 as B: in the BIOS. That way, I can access the 5.25, format floppies and read/copy files. The 3.5 however does not work (tells me drive not ready). If I disconnect the 5.25 the 3.5 works (note that I have to physically disconnect it, just disabling in the BIOS does not work.
So my machine more or less does the job, but I have to alternatively connect or disconnect the 5.25. Am I missing sometĥing ? I've spotted a cable on ebay with the IDC connector _after_ the twist, could this solve my problem? The 3.5 drive has no jumper visible, and the 5.25 has only one that seems to define if first or second drive (I can only access the floppies if I set it to second, at least on my cable.
Any advice is welcome,
Thierry
