Information, user manual and Philips DOS diskettes for the Philips P3105 8088 desktop PC.

p3105a.jpg


The manual contains information on how to connect the machine, complete first setup, how to install DOS and Jumper / DIP switch information. The manual is about the 5.25 inch version but is applicable to 3.5 inch versions.

Official PHILIPS floppy disks:

4 x DD 5.25 inch floppy disks with Philips DOS 3.21. System, supplemental, help / gwbasic, tutor.

1x DD 3.5 inch floppy disk with Philips DOS 3.21.01

1x DD 3.5 inch floppy disk with Philips DOS 3.30

1x DD 3.5 DOS TUTORIALS.

The diskettes include:

speed.exe to adjust the CPU speed. (SPEED standard for 8Mhz, SPEED Turbo for 4.77Mhz)

Wdhdinit to low-level format hard drive

PARK to park the hard drive.

Various utilities and diagnostics files to configure the default ATI Graphics Solutions Card. (See manual for more info.)


The P3105 has an onboard IDE connector. But the controller is XT-IDE.
XT IDE is an 8-bit version of normal IDE and is not forward or backward compatible with 16-bit IDE.
Only special 8-bit XT-IDE hard disks work.
These are very rare and do not work with normal IDE controllers. Fortunately, the computer also works with a controller in an ISA slot, allowing MFM, ESDI, SCSI hard drives to work.
The standard hard disk is a miniscribe 8425XT (XT-IDE) and it is known that the heads are stuck or that the engine start circuit is no longer working. Try turning the hard drive at power-on, or turn the lower flywheel by pushing a screwdriver against the edge when power is on. The flywheel is under the circuit board.

Let it run for a few hours and then it will hopefully start itself again. Sometimes it is necessary to turn on and off several times.

Do you have an XT-IDE hard drive and would you like to get rid of it? PM me!

Thanks for that.

Philips is one manufactory I believe a lot of manuals from the past are missing.
 
Hello.

I know this thread is almost 8 years old, but I am desperately searching for the floppy disks for my Philips XT (P3105). I have a working device, but unfortunately, I don’t have the original disks. I’m particularly interested in revisiting the TUTORIALS disk. Unfortunately, the links provided in this thread no longer work. Could someone perhaps share valid links with me?

Have a look at the Philips part at the Homecomputer Museum. Then have a look at the NMS9100 -and- the PC3100 part. Although these are different types, I used system specific software of the NMS9100 on my P3120 for handling the RTC and turbo-mode. Maybe a problem: the images are in TD0 (Tee Dee ZERO) format, have a look at Dave Dunfield's site.

I also uploaded a ZIP to my site containing the content of a disk where I found the programs mentioned above. it does contain a directory TUTOR but I haven't had a look at it yet (no need IMHO). I hope this is what you are looking for.
 
FYI: I started to disassemble the BIOS and the clock program. In both cases I was wondering who had programmed that. Certainly in the case of the clock program, here it was quite a lot of setting and resetting some bits of I/O-port 0C0h. Just minutes ago I found this piece of comment in the issue part od 86Box in Github: the p31xx has an I2C PCF8573T clock IC on board and this 0C0h I/O-port does the I2C communication. Now I have to find out why the BIOS needs to address the ports 0C1h, 0C2h, etc. In about a year I will retire and then I have some more time at hand :)
 
I had a look into the P3105 3.5 DD DOS TUTORIALS.IMA and, as far as I remember, it this could really be the program I've been looking for. I used it about 35 years ago when I got my XT (my first real computer after a VIC-20 we bought used) but I can remember retyping the commands as explained by the INTRO program.

THANK YOU SO MUCH!

I have bought two different P3105 (not sure if mine was this exact model) to assemble my very special configuration (768kb of ram, 1.44 MB disk drive, VGA, no hdd), but I don't find the time to finish this project. At least one of them is working and I've got a VGA card running in this machine too. And I've got original MS-DOS 4.11 which came with my Philips machine (but not original Philips disks).

But there are a few more machines I'd like to have up and running - maybe I have taken on a bit too much

The original P3105 had 512 KB of RAM. But by adding 2 44256 ZIP modules, you would have 768 KB. My P3120 came with a VGA card branded as Philips. But 1.44 MB? IMHO that should be 720 KB. Please check that. If it is indeed 1.44 MB, I'll have to have another look at my P3120.

I bought this Philips 8088 XT in 1989 oder 1990 in Amstetten (Austria) for ATS 9.999,- in an electronic market (Hartlauer) at a time when they were already selling 80396 machine and it indeed had factory-installed 768 KB and a tool to use the 128 kb as a ramdisk (which i used to store the command.com so I did not have to insert the system disk after every program I ran). I am also sure that it hat an 1.44 MB 3,5" disk drive even if these should not be compatible with XT bioses (at least thats what I have been told). I once brought it back to the electronic market to install a 1.2 MB 5,25" floppy but this drive did not work and I only got an 360 KB Floppy for twice the price. I borrowed a 20 MB hdd from a friend which worked in the Philips XT, but I had to return it after a few weeks.
I do not know the exact model number but I sold this machine in 1993 when I got my 486DX50 and the buyer killed it within a week :'-(
 
OK, I will first check what drive I have, will replace it with an 1.44 MB one and give it a go.
