Hi Antun,

I do not exactly understand what you ask from  me.
Should I give regular updates that the BDP-1 's still work?
That's quite impractical!

The BDP-1 's could fail due to many causes e.g.


1) Software

With the old S0 firmware "Candian Beaver"and the BDP-1 's not hooked up to a NAS or the Internet, there is very little chance that the software gets corrupted ( The 4GB CF disk being the most likely candidate).
But the latter would be no problem because I have back up Trancend CF 4 GB 133X cards, with the S0  firmware installed.
It would be simply a matter of replacing the existing  4 GB CF card by a spare CF card with the same S0 firmware.


2) Hadware

The BDP-1 player is very well made and uses top notch components (see picture)

However hardware can fail , of course, as well:

AA) Power supplies (5V, 12V , 3.3 V).

These consist of
- 1 Meanwel PM05 5  ,  5V 1A switched power supply (SPS)
   (https://www.koningenhartman.nl/nl/webshop/industrie/industriele-voedingen/medical/mean-well-ac-dc-psu-pm-05-5-modular-5v-1a )
- 1 linear 12V Power supply.
- The 3.3V is derived from the 5V power supply.

If any of those Power Supplies would fail, any competent technician could repair those.
The weakest points are iIMHO, the Meanwell PM05 5 SPS and the 2  big  6800 uF 25V Chemicon electrolytics (but these are Hi Quality and survive > 35 years in Amps)..
NB I do not think that the Toroid transformer will ever fail, but this  is also easily available.

BB) PC Engines ALIX  1D (2007) industrial PC Board.

In case of internal  failure (no beep upon start up: most likely indicates a broken circuit) the BDP-1 is IMHO Totall Loss.
Bryston might stilll have spare ALIX D BOards , but the costs of repair will be prohibitive!

CC)  PIC, USB Front Panel, VDF circuit and switches boards

If the PIC Board would fail, a similar story to BB) above : much too expensive to repair and not repairable if the PIC programme is not available.

- It might however be an sensible idea to stock a spare VFD display  : 
 
  FUTABA GP1184A01A
  NORITAKE GU140x16G-7003

You might inquire with Bryston Ltd, whether they would be willing to supply a VFD board  to a Private Client.

So, in your case, I mostly would address the software side of business : make an image of the HDD (SSD?) or CF card of the operating system.

For the rest: do not change anything, if not required:  Enjoy your BDP2 (and BDP-1?).
