Amiga Sidecar A1060 Repair [2]

I got a spare edge connector from some nice Italian guy and I soldered it in. It works perfectly!

I also bought a replacement MFM harddisk via someone at A1k.org. I got it to work after many tries by circumventing bad sectors on the Amiga partition. As the MS-DOS-partition avoids these automaticaly, the Amiga apperently does not. So I chose the cylinders that are not bad for the Amiga side. The partition is quite small, but it works well now.

Amiga Sidecar A1060 Repair [1]

A long time ago I bought an Amiga 1000 with a A1060 Sidecar. A Sidecar is a complete PC XT-clone made by Commodore. It has it's own housing that is attached to the side expansion bus of the A1000 and uses its periferals. The unit I bought had a hardcard in it: an MFM-controller card with harddisk. It worked perfect. But it doesn't anymore. I bought another one, but the disk only worked once.

This picture is not mine. I took it from https://compidiaries.files.wordpress.com.

The harddisk stopped working and the many times I attached/detached the Sidecar to the A1000 trying to get it working again has made the connector fail. One or more legs of the 86 pin edge connector do not make contact and aren't easy to repair. A new edge connector is rare and expensive. Only Digikey has some to offer but you pay almost € 70,00! So I put up a Wanted ad on Amibay.com and now I will get a desoldered connector from some guy in Italy.

Another problem of the A1060 was the 360kB 5-1/4 inch floppy drive. I didn't know if it was working because I didn't have MS-DOS system disks in 5-1/4 inch. I now managed to get a drive and attach it to an older PC. After much trial and error I now have a system disk to boot the Sidecar once it is repaired.

ISA CF adapter for the A1060 Sidecar [3]

I stumbled upon this thread. It learns me that the ISA CF adapter will not work with the Sidecar because of conflicts in the BIOS. This can be solved, but I don't have the skills nor knowledge to perform this.

So this is the outcome at this time of the ISA CF adapter adventure.

I tried the Western Digital Filecard and it worked a few times. After that the Amiga partition vanished. So it's not reliable anymore.

ISA CF adapter for the A1060 Sidecar [2]

I digged up the A1060 sidecar and connected it to my spare A1000. While it booted fine, it did not recognize the floppy diskdrive. So I thougt I format and prepare a harddisk, connect it to the ISA CD adapter, and hope the Sidecar would boot from it. It didn't. It repeats bleeping when the floppy diskdrive is needed, the drive's light blinks for two seconds and it starts over to check the RAM. And over and over again.

I now believe the floppy disk drive is faulty. As I have no spare I need to get one.

ISA CF adapter for the A1060 Sidecar [1]

I have an Amiga A1060 Sidecar. This is a fully functional IBM XT PC for use with the Amiga 1000. In the Sidecar was a Western Digital 30MB Filecard. This is a harddisk controller with attached harddisk.
This harddisk got faulty, so I tried to obtain a new one, but i couldn't find one. Now I will try to get an XT-compatible ISA-card to work. I bought a kit. It has a 40-pin connector to connect harddisks or CF adapters.

That was the kit and now soldered together:

I will keep you informed!
