IBM ThinkPad 760 Series MIDI/Game Port Adapter

While doing my research for another project (finding a plug for the Philips CDI350 RGB in/out port), I came across an old IBM MIDI/Game port adapter. It is listed with P/N 29H9467 (FRU P/N 29H9269) and can be used with some models of the ThinkPad 760 series (760CD, 760ED, 760XD, and also 765D). What makes it so special is the plug. It is similar to the 26-pin external floppy connectors used by several laptop brands in the ’90s. While most of the external floppy drives used a 17 mm wide plug, this one is 20 mm wide. This JAE datasheet lists the plug as TX20A series connector, part number TX20A-26PH1-D2P1-D1.

Amiga CD³² Recap and TF328

This repair was not planned at all and took place while I was waiting for the capacitors for my CDI350 to arrive. I was thinking about buying a SX-1 or SX-32 extension for my Amiga CD³², and was recommended to go for a much cheaper modern extension: the TF328.

The TF328 needs a Kickstart 3.1 rev 40.60 to access the CF card, as there is no IDE driver in the earlier revision 40.56. Upon checking my CD³², there was not only the smell of electrolyte, there was also visible damage caused by leaking capacitors.

Philips CDI350 Repair Part 2

Last year I began to disassemble and repair one of my Philips CDI350 players. This has been covered in the article Philips CDI350 Repair Part 1.

After that, it took me a while to make a list of all capacitors, to find replacement parts (the original Philips part numbers are not useful anymore) and to find shops that had them on stock.

The scanned CDI350 service manual on ICDIA is missing the pages 78 and 79, which contain the parts lists of the servo and power sections. I found some of the missing parts in the CDI360 service manual and some by comparing the removed parts with both service manuals.
