domesday

Post by balladof32 » Tue Mar 27, 2018 8:52 am

well I finally snagged a genuine aiv , I'm halfway there minus the vp415 and any discs . once the domesday is in place I'll thin out the rest of the acorn collection which isn't huge by any means , but I will have some interesting acorn and related parts that's will be for trade if anyone can get me towards the 415 and any discs . 415 doesn't need to be working but does need to be complete . I do have an original AP6 which does seem to be pretty sought after so I'll throw that in the mix as a potential trade item . I do prefer to trade bits but will part with cash if preferable . Any simple pointers in the direction of anyone selling a player or the discs would also be appreciated . Thanks in advance :-)

Hi,

I know the problem, I have all the hardware even a working LV-rom player (VP415),, but not any disc(s)... :-(

So still looking for them too... O:)

I think it's up to them to self identify, but I'm only aware of about 7 people with working 415s outside of the two computing museums...

So far I think I'm the only one with an actual VP415... :mrgreen:

Everyone else (me too) has a (415) LV rom Player... :D

There is even someone with all the VP4xx flavours... :-

They look nice all stacked up but is there a point to actually owning them all ?

"There are of course many problems connected with life, of which some of the most popular are: Why are people born? Why do they die? Why do they want to spend so much of the intervening time wearing digital watches?"

It'll need a computer more powerful than a BBC Master to answer your question, I think...

Yes, for two reasons... :D

One, I really like the design of these VP4xx players, and two, this way I will always have "enough" spare parts... :wink:

I used to have one about five years ago. We were doing a clear-out at work, and when I walked into the storeroom, there it was! There was also a VP405 and VP406 in there, too. I virtually ripped up the carpets trying to find any other Domesday components, to no avail. In the end, we all agreed to send it off to The National Museum of Computing, as we believed they'd get the best use out of it. I had no idea if the thing worked, and no way to properly test it as such. I do sometimes wonder what happened to it; I hope the museum got some good use out of it.

Hi,

did you find by any chance a remote for this VP405?

It looks like this: (see hazy pic)

No such joy, I'm afraid. After I found that, I pretty much tore the place apart looking for related bits and pieces, but didn't find anything else from that era apart from the players.

I think all the VP4xx series can share the same remote, the one supplied with the Domesday System works with them all. It can take a wired link for players without an infra red sensor on the front.

Hi Ian,

I know, but I like to find me the original one one day... 8)

For those of us lucky enough to have a complete, working Domesday system, the prospect of the laser disc player failing is a constant concern. I have a VP410 as a backup to my 415 in the hope that I'll be able to harvest it for spares as and when they're needed [-o<

Yes indeed, and one of mine is a cobbling together of a working VP410 and dead VP415. And in the 15 years since I got hold of my first Domesday LV-ROM discs, they have degraded significantly to the extent that it is affecting video playback now. Probably in another 5 years' time they will be unreadable altogether.

Much of these concerns are the basis of the Domesday86 project...

Failing VP415s can be repaired (I've personally brought two back from the dead so far); I've made high-resolution service manual scans available and also disassembly and calibration guides (as well as a visual reference to all modules front and back).

In addition, the Domesday Duplicator project is designed to make high-resolution scans of the laserdiscs in sufficient detail that new discs could be made from the images (i.e. proper round-trip preservation). The duplicator project is about to hit it's second generation of design, but it's already capable (and proven) to be able to back up discs. There is also a lot of interest from the MAME project now around using the Duplicator for many other specialist laserdiscs as it meets their high-standards of 'correct' preservation. There is even a sub-project in MAME to emulate the VP415 aided by the availability of EPROM dumps (with accurate versioning and checksums) - dumps of the NEC8041 slave CPU ROMs (a first from the dd86 project - these were not preserved before).

BeebSCSI also acts as detailed documentation about the inner-workings of VFS and the VP415 on a SCSI interaction level (there's the equivalent of around 75 pages of documentation for this part of the project alone).

SmallyMouse2 provides emulation of the Domesday RB2 trackerball device.

There's also some demos on the project youtube channel showing an entirely solid-state Domesday system booting and running. As well as a collection of documentation covering every manual, laserdisc, variant, press-release, etc. about the system.

Also every part of the project (Domesday Duplicator, BeebSCSI, SmallyMouse2, a VP415 emulator, 8041 ROM dumping utility and more) is open-source and open-hardware, released under GPLv3 and CC ShareAlike.

https://www.domesday86.com/

P.S. If you want to help; dump your player's EPROMs, scan documentation I don't have, donate or simply reply "awesome!" whenever there is progress :)

Edit: Here's my Domesday system - It's an export AIV system (note the Swedish keyboard), the only one known to exist:
