# List of parts to save from the Macintosh SE Board
* **SIMM Sockets** - NEARLY IMPOSSIBLE TO GET. If you can get some from here: https://www.peconnectors.com/sockets-pga-cpu-and-memory/hws9229/ then do so!

Re-using and cleaning up your old ones involves desoldering. These need a lot of heat as there are a lot of connections to the ground plane. Pre-heat the joints, maybe add a dab of proper Kester 63/37 eutectic LEADED solder (none of that RoHS crap), flood with flux. 
* **PDS Socket** - Amphenol/AMP/AVX DIN-41612 3-row, 96-pin connector (Style-C) - Available new, but still worth reclaiming as sifting through the minute variations of parts is an arse...

* **GLU Chip** - Apple branded HAL16L8 - this has been reverse engineered for both GAL16V8 and discrete logic!
* **BBU Chip** - Custom Chip
* **NCR5830/AM58C30 SCSI Chip** - NLA, only available as NoS or Reclaimed from UTSource
* **WIM/SWIM Floppy Chip** - Custom Chip - available NoS from UTSource
* **IWM/SWIM Floppy Chip** - Custom Chip - available NoS from UTSource
* **Hi & Lo ROM Chips** - Toshiba TC531000CP MASK ROM's - Reclaim & reuse, but these are the same pinout as 27C512, but adds A16 in place of VPP pin - you can use 27C010's on an adapter - doug brown made a similar setup with a built in ROM disk for the Mac Plus. 
* **74LS245** - Available new, but still worth reclaiming - replace with CY74FCT245ATPC or CD74FCT245E
