  1. They look a little different at the hardware level. PC-Link looks to be real I2C (IIC), with Keyboard overlayed on the same PS/2 connector. Control-A1(II) looks to be a proprietary hardware interface - although admittedly it has similarities to I2C, viz an open collector output with passive pull-up. It may be that the bytes that are sent over these three interfaces are essentially the same. On the 770 the PC-Link, Keyboard and Control-A1(II) have independent connections to the uC. Looking at the uC pinout/datasheet, the PC-Link I2C is served by a dedicated I2C engine in the uC. The K
  2. I'm not going to argue with the boss (he might ban me!) :-D Looks like I need to hit the schematics for the 770 as that seems the machine that has all of these on! The devil is probably in the firmware though. Maybe the 770 was a "more interesting" buy after all!
  3. Yes it seemed to have an annoyingly short life. MD-wise it seems to appear on the 920 (but not the 520) which would be 1998, lasting though the x30 range and I think the 770 (2001) was the last. Not sure about the 640/940 without downloading the manuals. So maybe 8 or so MD decks? CD decks seemed to just drop it, and MD decks migrated to USB and PC-Link connectivity, rather than deck-deck connectivity.
  4. They don't. They stare blankly at me. And then 150 audience also turn and do the same. Then the kids (in the audience) start screaming because the Fairy isn't singing her pretty song which keeps them at bay. British Panto - a daily roller-coaster of fear and near-panic for the cast and production crew. A delight (hopefully) for the audience! The audience love it when things go wrong. They like to see the fear and panic in your eyes.
  5. Exactly. So far I've been lucky. MD reliability is good (which is one of the reasons I switched back to MD). But I'd like a get-out-of-jail card if I can. With my "new" MDS-E12 and CDP-D12 rack I have in principle a backup machine (2 E12's "on-line" [1xSFX, 1xMusic], plus 1 E12 "backup"). Thus I need a backup disc of both the music and SFX to be able to use should a machine or a disc go down. Probably I'm paranoid! I can do CD-MD dubs with the Tascam MD-CD1 - the material is prepared on a PC, written to CD-R then dubbed to MD. The trouble is the CD-R to MD dub on the MD-CD1 is not fully reliab
  6. Well ok, so it took me 3 years, but hey ho. Using an MDS-E12, recording a track (or disc) with Copy=Permit, I was able to make 3 generations of digital (TOSLINK) copy of the track using an MDS-JE770 into an MDS-JE530. The point to note here is that I thought the 530 (as a consumer deck) might force the COPY bit on the 1st gen digital copy. It didn't, it still propagates the "copy permit" status which allows further digital copies to be made, even consumer-to-consumer deck as above. Note the 770 and 530 were also connected with Control-A1(II). Unfortunately I couldn't get the titles to cop
  7. I’ll say nothing more than ‘great news’! These things are sent to try us.
  8. Thanks for the Groups info - very interesting. Something I've yet to play with (my list of "to play with" is quite long!). Fantastic! That's what I love here - contributors who will take an extrapolated thought and try it out! Shame it didn't work, but great idea! :-D
  9. Also as it was the issue a couple of posts ago...! Make sure the remote and keyboard don't have buttons pressed!
  10. The titles are stored in the TOC, the audio in the main part of the disc. Regards Groups - this is only on a few later decks and portables I think. It's on my 770. However I don't know whether this is an "on deck" feature or whether it's some information that is stored in the TOC on the disc - I suspect it's the latter, but I don't know anything about how Groups are handled and what the effect is on a non-Groups machine (none I would hope!).
  11. Weird. If you haven't, might be worth a mains power cycle - as in unplug for an hour or so and then replug. Sounds like the uC getting it's knicker's in a twist. On your first point about track names - audio and track data are allocated separate space on the disc, so full audio shouldn't impact adding titles. There is a limit on title space, but it's relatively large. I've only ever filled track space up once and this was on an audio test disc (sine waves and the like) with about 100 tracks and some pretty long titles on many of them.
  12. It wasn't my intention to spam and detract from this thread but I've clearly messed it up. Sorry to @Trumie35. Only this, no excitement required!
  13. Anyone got any tricksy idea how to read personal messages on the phone version of the site? When I’ve a new message I can get straight there. If I want to revisit messages I can’t find a button anywhere. I must be blind. I can’t even see a mechanism via my profile page.
  14. A.CUE+MENU is a version report. VARISPEED+MENU is a relay check and FF and VARI buttons seem to toggle the p-out and e-out (from the schematics these seem to be "pause out" and "end out").
