Hi guys, I'm working again in this two computers, well, right now with the T1000XE.
I managed to make a cable to connect a standard PC floppy drive to the parallel port/ext floppy connector. I leave the pinout here for you and the way to make it:
You just need an standard PC flat floppy cable, a DB-25 male connector and a floppy drive of course.
Cut away the connector from the mainboard side of the floppy cable, and separate each cable leaving like 2" / 5cm free. Also strip a bit from the end on each wire.
Then you just have to solder following this table:
Code:
DB25 Flat Ribbon cable
---- -----------------
1 1
2 8
3 26
4 28
5 30
6 34
10 14
11 10
12 22
13 24
14 2
15 32
16 18
17 20
18 GND (ODDs)
. .
. .
. .
25 GND (ODDs)
Odd wires from flat cable (1,3,5...33) are all GND.
You have to connect them to pins 18..25 on DB-25 connector (all GND also)
I did it soldering two or three on each pin.
Then you have to connect the drive to the A: connector on flat cable (the one with the twisted cables), and to supply, I used a standard PC ATX supply for this. Also you have to run setup10.exe on the T1000XE (on the bios drive) and set the parallel port from printer to FDD-A, save and reboot.
If everything is ok, you can now boot from and use the external drive.
Pictures:
Forget the blue wire in this picture, it was wrong. The toshiba external drive uses a signal that is not present in a standard PC drive, but for normal use it has to be logic 0, so I soldered it to GND like in the table (DB25 pin 1 to wire 1).
Now, I have a problem. I was trying to install MS-DOS 6.22 on the internal HD, but if I install it and set the bios to boot from HD, it stalls in "starting ms-dos...". If I do a sys c: with the msdos 3.30 that comes in the ROM, it works and boots, but I tried with msdos 6.22 and also with 5.0 and it hangs just there. Weird because both of them boot from floppy.
Any ideas?
Thanks.
