Flashjazzcat's Blog > Poor Man's 1400XL: Part 9

Posted 11 April 2013

After a long gap, here's the last (or possibly penultimate) part of the 1200XL upgrade story. In the last part (well over a year ago), I'd fitted VBXE and Stereo Pokey, and finished the PBI and power mods. Since then I've added Ultimate 1MB and one of Dropcheck's excellent GTIA PAL adapters. This means that the 1200XL is completely "PA...

Welcome to another thrilling installment of my 1200XL's story. Prior to fitting the Ultimate 1MB board when it arrives, I decided to install the Mega-HZ stereo board.

It seems I left the most important part of this mod almost till last: the PBI itself. I'm following the (amended) instructions by Bob Wooley (PBI for 1200XL), but it took me a week to find a suitable bracket for mounting the 50 way Centronics connector to the back of the motherboard. I...
