Philips P3800 TurboDos - infos anybody?

[spiceminer]

Hi everybody,

I got a Philips P3800 System today running TurboDOS 1.4. Apparently, it is a 8088 architecture (not Z80 which I expected).
Unfortunately, there is only some information on the P3500 (Z80/CP/M comaptible?) available, but not on the P3800.

Does anybody has Information, Software, Documentation or some other related info on this specific machine?


The most important point deals with the startup procedure: it is asking for a username/password, which I do not know. Is there any procedure to apply to reset the passwords? Or is there a standard maintenance password available?

Attached a short video showing the boot procedure

Thanks a lot and best regards
Stephan


..the unit is really heavy >50kg. My compact car was completely filled (main unit, two terminals, two heavy printers with stand,....)

Bitsavers has TurboDos manuals though I don't see any disk images for 1.4. http://www.mirrorservice.org/sites/www.bitsavers.org/pdf/ims/turboDos/ Good place to start. I think that TurboDOS passwords could be cleared with a boot disk.

http://www.cpm8680.com/turbodos/Tdos4.htm explains the password storage method.

https://translate.google.com/transl...z80.de/showtopic.php?threadid=532&prev=search gives one attempt to do that. If you understand German, drop to the original.

Hope this helps a little. I am relying on web searches to supplement vague memories.

Thanks a lot.
Next step is to save the content of the two MFM hard drives with the famous MFM emulator from David Gesswein https://www.pdp8.net/, hopefully it is possible reconstruct the file structure and to read the password file.

The computer museum of the Amsterdam university may have the manuals. I am in contact with a friendly guy from that institution, I will keep you updated on this matter.

Best regards

I managed it to get a set of 5 Turbodisk Disks. It was possible to create images and extract the files for preservation. If anybody needs them please leave me a message.

I've just a lot of manual for the P3000 series on the table .

As I just see there are even some documents for the Philips P3500 Turbodos system on https://electrickery.nl/comp/divcomp/doc/
but you have to scroll down some lines.

Hi!
I have another Phillips P3800, but I lack the terminal.
Mine have even the terminal cables exiting from the back cut :-( Do you have any info on that cable, perhaps some technical manual?
I'm interested on the manuals and the disk images for sure!! Are they already scanned anywhere

Hi,

that's for 3500, maybe spiceminer has more for the 3800 as he got even some terminals.. I remember he had images of the system disks

All I found for 3500 is on https://electrickery.nl/comp/divcomp/doc/ , the disk images I got are all scanned and even there. I hope I sorted them in a usefull manner.
I hadn't any terminal for the system nor some manuals about them. Information's from Philips are rare and I hope you will find some helpfull .

Some more information's about turbodos are at https://oldcomputers-ddns.org/public/pub/manuals/turbodos/index.html and https://oldcomputers-ddns.org/public/pub/rechner/philips/p3500/index.html

and I believe the pictures for the 3800 are from spiceminer at https://oldcomputers-ddns.org/public/pub/rechner/philips/p3800/bilder/0.gallery.html
