The reverse video switches between dark background/light text to light background/dark text. I prefer dark text/light background because less pixels need to be activated (help the batteries).

Backlight has three settings dim, bright, and OFF.

I have used an 8MB IC DRAM card from a 720 with no problem.

Might be able to use 32MB IC DRAM cards. (TP370 32MB card fails - wrong memory speed).

Compatible Stylus (Styli?)

I'm looking for a few pens for the 730 TE. IBM can deliver, but it will take 4-5 weeks. Does anyone know where I might get quicker delivery? Can I use other brands of pens on the Thinkpad? I expect it's quite easy to get hold of spare pens for Windows CE machines.

RLS104 replies:
   The Win CE pens will not work on your 730. In general, any wacom pen will work - it's used on the Mitsubishi Amity's, the old Toshiba T100 and T200, and all pen enabled Thinkpads. The CE pens are really just sticks - no electronic properties, whereas the wacom pens have some electronics in them that enables, for instance, the right mouse button from the button on the barrel.

I used to have a 730TE, and have had a TP 360PE and it worked on both of them. Both of them have the same video driver and digitizer as your 750P, so there should be no problem.

External Diskette Drive (Opt. TOGP14M) 48G8263

"Just wanted to advise that some of the newer Thinkpad's External Floppy Drives will function with the 730T. I was using the External floppy from my 765D system, FRU# 66G5069 P/N 66G3696. The floppy drive is also used in the following Thinkpad units, the 360, 355, 370, 701, 755, & 760. This drive unit should be easier and less expensive to obtain than the original unit"

External Diskette Drive Checkout

A scratch, write enabled 1.44MB diskette is required.

  1. Select FDD icon on TEST MENU. This runs the controller test and drive read/write test. If the test detects an error, FRU code 10 appears. In this case, replace the system board.
  2. If controller test runs without errors, follow instructions on the screen and insert floppy.
  3. If the drive test detects an error, FRU code 50 appears. If the diskette media is known to be good, replace the drive or the drive cable.

Mouse Use

IBM says - "Mouse devices such as PS/2 Mouse and Microsoft Mouse are not supported. The Stylus Pen should be used as the pointing device instead of using a mouse."

Alfred Arnold reports:
   Might be that it's not officially supported, but that doesn't mean that it doesn't work. My TP730TE came without the pen, so I had to look for an alternative. Got a Y-shaped adapter from a friend that has a PS/2 plug on one end, and two PS/2 sockets at the other end. The sockets are labeled 'Mouse' and 'Keyboard'. Stick the plug into the replicator's keyboard jack, you plug in the mouse and the keyboard into the two sockets, just like the two PS/2 sockets of an ordinary machine. Works like a charm - at least under Debian Linux...the adapter is entirely passive, so the signals for mouse /and/ keyboard must be present on the 730's keyboard jack.

From me, god-Emperor of Microchannel
   Picked up a PS/2 splitter from Ebay. I used a Model M keyboard. First attempt failed with the Model M on the keyboard cable of the splitter - the LEDs didn't light up during POST. Swapped the keyboard to the mouse cable of the splitter, tried again. It works. Now to load something with mouse support...

Space Saver Keyboard Usage (84G2524) (from IBM Announcement)

To attach a space saver keyboard through the port replicator, a Y-cable is required. The Y-cable connection must be reversed so that the keyboard is connected to the mouse connector of the Y-cable and the mouse is connected to the keyboard connector of the Y-cable.

Digitizer System Resources

The system reserves COM4 (base I/O address 3E8h), IRQ 5 as the internal digitizer communication port. For serial I/O communications like the external 232C or PCMCIA modem cards, use COM2.

External CRT

When the external CRT monitor is attached to the system, the CRT monitor supported is VGA (640 x 480, 16 colors). The LCD and external VGA CRT are simultaneously displayed.
