Way back in the mid 80s I saw something unique at the Dayton Hamfest. It was an 8 track open reel tape machine, but it was a machine control telemetry recorder. It could record and play analog control voltages, including steady voltages other than zero because it was FM. I have no idea what the bandwidth was, but I thought it was pretty interesting.

Good old fashioned hand wired breadboard build- no surface mount stuff here! I was beginning to think nobody does it this way anymore.

Awesome!

Agreed!

Reminds me of Ben Eater's videos on building a video card, an 8-bit microprocessor, and a 6502-based computer, all using breadboards and point-to-point wiring.

I've contemplated buying one or more of Ben's kits to assemble for myself, but I've always held off because I know I won't have the time to finish...

Greg,

I gave all my 1/4" reel to reel tapes back to dsli-jon, who probably forwarded them to Lumalaser. Lumalaser has digitized those tapes and will probably use the files in whatever they have planned for the "Bride of Laserium" return of the shows. However, I do still possess a few beta and ADAT tapes that probably have 352 data on them.

I'd have to take inventory, but I may have these in betamax tape format:

Laserium I

Light Years

Crystal Odyssey

Laser-Rush: Grace Under Pressure

Led Zeppelin: In The Beginning

Grateful Dead

Rainbow Cadenza: Classics

The Police

Laserium Zodiac (Zodiacal Light)

Moonrock

Flashback: '80's (Laseroq: the 80's)

Laserock: Into the '90's

Summer of '69

David Arkenstone: Celestial Dreams

Led Zeppelin: In The Evening

U2

Rock-It '91

Star Trek: The Astral Symphony

The Doors

Hot Led: Zeppelins' Best (Molten Led)

LASER HOLIDAY '92

Laserium Rocks!

the cure: wish

Dream On: The Music of Aerosmith

Inside Laserium

Lollapalaser

Laserium Rocks San Francisco (KGB)

And I only have Metallica in ADAT

As you know already, I have almost every soundtrack (digitized from sometimes questionable tapes) on CD.

Thank you for the reply, Ron. That sounds like a significant trove of potentially recoverable material. I have the infrastructure in place to digitize, decode, and visualize a 351 data containing audio signal, as demonstrated in some of my previous posts. I have no idea however, how the betamax format fits into the Laserium picture. Is a modified betamax deck required to obtain the useful signals on playback? Do you know any details regarding what signals are recorded on the tapes and how to access them? Was an external decoder needed to demultiplex the audio from the show control signals?

I very much enjoyed hearing your words of wisdom on the Laserium video. I wish I could have seen some of your performances.

Results are in. The XYRGB signals produced by the 6b rebuild are being recorded and played back synched to audio by using the BELA platform. It works admirably. The cycloids including the color mod look the same whether they come from the analog circuits, or from bela.

This bodes well for putting together something in the way of a four channel system that plays 351 the way it was meant to be seen.

Is the Betamax multiplex compatible with the Image Engineering decoder i have in storage?

I have goosebumps all over!

Multa BELA!

Maybe slightly off topic, but does anyone know of a way to decode the Ch6 data for ADAT midi that usually fed a midiana without recreating it from the schematic?

[laserist]

According to the documentation I've got (thanks Ron) the MIDI was recorded on chan 5 of the "A" tapes. Chan 5 wasn't DC. I'd look at it with a scope. I doubt an ADAT could record a raw MIDI signal worth a damn. It's probably a 1/2 speed or slower version of a MIDI signal that would need to be buffered and sped up. I looked at the schematics once, but since I didn't have the software/eprom info I said thanks but no thanks. The Midiana controlled the Lumia and intensity - which really is MUCH better performed live...

[mixedgas]

Anyone have the manual for these scanner amps?
361 71 D

They will probably end up with Greg.

Three of them were in a non-laserium projector at SELEM and followed me home.

Steve: I sent an email before I saw your previous post. Wow!

TheHermit: I think that's pretty much about it, yeah. There is no ADAT involved anywhere on my plate of spaghetti, and the ILDA block in my current setup just means single ended to differential amplifiers, nothing to do with ILDA data. But results suggest you're right about all the possibilities involving using bela as a small cheap digital real time ten track tape deck. I'm happy to provide my codebase if it helps anyone make use of this functionality.

I like and will go with lasermaster1977's coinage for future references to achieving a 4 channel 351 data inclusive Multa BELA scheme.

Brian: I'm wondering if I am overlooking a 3.28 MHZ oscillator circuit somewhere in the 6b-DNUB.pdf

Ron: Your photos have proved invaluable in the past. If you ever come across a Danube board, that would be a timely one to see.
