Amiga collection is growing - A1200 added

As mentioned in my previous post, I managed to secure an Amiga 1200 and 500 through a Gumtree seller.  The A1200 Rev 1.D1 cost $200 and was an original purchase by the previous owner as was the A500 Rev 6a with a genuine A501 expansion that cost me $20 (it had a non working keyboard)….and 208 various Amiga magazines with cover disks.  I felt like a kid in a lolly shop..All my Christmas' come at once.

I've swapped the Rev 6a A500 mobo into my A500 that was running a modified Rev 5 board and it is now one sweet machine.  I had to pull the Varta battery from the A501 as it had leaked a little and corroded a small section of the board. I replaced the Varta with a home brew button cell and diode to prevent the charging circuit from trying to charge the lithium cell.

I spent a good 3 hours re-capping the A1200 yesterday as it had never been done according to the previous owner.  Again, I think I caught this in the nick of time as a few of the caps had leaked but I was able to clean up fairly easily.

The picture below shows the worst of the leaks before cleanup.




































I gave the A1200 a test run last night and I'm pleased to say that it works a treat.  I threw an old 20GB IBM laptop drive that I found in my stash of old bits and installed Workbench 3 and happy days, it passed all tests that I threw at it.

I have a CF adapter on the way that will take the place of the HDD and also some physical 3.1.4 ROMs that will take the pain out of HDD management

I will order an Individual Computers accelerator card when funds are available and also a Flicker Fixer (likely to be a MK3 according to Jens as there are no more MK2s left for sale).
