Micro Lynx + Tape Deck + DAW

Every time you boot up, you have to select your session Group (A, B, C) ...that's not retained.
The setup for which machines is assigned to a given transport connection (A, B, C)...are retained.

I think that's what you are asking...?...and I think I said that right. :D
 
Thanks for the post back miroslav. Good to know that I'll have to Select the Group before starting a session, but that the Group machine contents are retained. I'm just getting started on the Installation chapter (Ch.3) which covers the Initialization responses to Power Up. Glad I posted my observations, as my bench is away from my computer.
 
OK, after giving the Installation chapter a once-over, I got the Microlynx to give me back a readout of the supported machines, and the machines I'm wanting to sync all had an individual menu listing (Alesis AI-2, Tascam MSR-16, and Otari MX-5050 Mk 3). Yee-Haw! I also managed to pop the lid and check the EPROM versions.
Here are the specs:

System Unit
Chassis Serial Number: 1537 (newer metalwork than serial #1024)
Installed Options:
1. VSG - Video Sync Generator Daughterboard
2. M3 - Third Transport Option Card
3. ACG-2 - Audio Clock Generator Option Card w/Wordclock, Superclock, AES/EBU (on
9-pin D-sub connector)

Motherboard- ASSY #70C021, Rev. 3B, Serial #1541 PCB #55A022, Rev. B

EPROMs: CP-1.34 (factory-labeled TimeLine copyright 1992), 2 of MC-1.33 (same date
on label), U19 = 76E001, Rev. H
Other Socketed IC's: U64, U65, U66, U67 = TCP627-4
Backup Battery (BT1) = Hitachi/Maxell Super Lithium ER-3 (1/2AA), 3.6Vdc, Axial
Lead (~30mm spacing), PCB Mount,
Body Dimensions: Diameter~14mm, Length~23mm
Microcontroller IC's: U15, U34, U37 - Siemens SAB 80C537-N, 8-bit CMOS
microcontroller. Its presence in certain PCB quadrants, and
proximity to apparently companion devices (the Xilinx XC 3020-70
FPGA IC's, for example) suggests that every Transport Control Port
needs one (U34 for Transport Port 1, U37 for Transport Port 2),
and that there is a "Master Processor" that controls the whole
System (U15).
Identity Redacted IC's = U22, U24 =14 pin Small Outline Integrated Circuits (SOIC)
surface-mounted to the PCB. Their identifying numbers have
been abrasively or chemically "scrubbed" off, although they
still have a printed mounting-orientation mark that looks
identical to a nearby identically-packaged Motorola device, a
4046 IC. I therefor suspect that they are Motorola IC's,
possibly from the same logic/function family.

Backplane I/O Daughterboard - ASSY #70C022, Rev. 2E, Serial #1546

Note: Has installed Kynar-style wire jumpers, visible on solder side of PCB with
chassis lid removed.
Jumper quantity: 4 insulated (black), 3 un-insulated. Believed to be
consistent with Service Bulletin #SB 92-009- "Computer Mac and MIDI I/F"
Mod for Mac connectors J9, J10: Cut trace on component side of PCB (see
Fig.2 in S.B.), Insulated Jumper wires added per Figure 3 in S.B. Unit has
optional "Time Code Out and Aux Out" Mod Jumper wires (un-insulated)
added between Ring and Sleeve terminal pins per each respective jack
(see S.B. Figure 3) all called out in SB 92-009.

Additionally, it has the following PCB mods:
1. Backplane Ground trace cut (solder side) between MIDI IN Jack (J6)
and AUX REF OUT (J6). Probably performed to separate Analog and
Digital Ground.
2. Trace cut on component side formerly connecting pin 11 of 50 pin
Ribbon Connector to Ring pad of AUX REF OUT.
3. Insulated Jumper wire added between Tip Pad of AUX REF OUT and pin
12 of 50 pin Ribbon Connector.
4. Trace cut on solder side formerly connecting pad of TC OUT (J3)
through a Trace Via to pin 11 of 50 pin Ribbon Connector. Insulated
Jumper wire added to take its place from Trace Via to Tip Pad of J3.
5. Un-insulated Jumper wire added to solder side between Sleeve Pad of
TCR1 IN (J1) and Trace Via that connects to Analog Ground trace of
backplane near E1 Test Point. This compensates for the Analog and
Digital separation procedure in Mod 1 above.

VSG Option Daughterboard - ASSY #70C025, Rev. 4, Serial #634

M3 Option Card - Machine Expansion ASSY #70C023, Rev. 1E, Serial #230605

EPROMs: MC-1.33 (factory-labeled TimeLine copyright 1992) (U4), 76603 (U9) - Xilinx
#1736 DCP for Xilinx XC3030-70 FPGA
Other Socketed IC's: U24, U25 = TCP627-4

ACG-2 Option Card - ASSY #70C026, Rev.3, Serial #261277, PCB #55A026, Rev.
C1
Note: PCB printing also refers to an alternate assembly
number, probably referring to another destination device.
That number was ASSY #70C030, but was "blacked out" by
something like a "Sharpie" marker.

EPROMs: ACG-1.33 (U12), 26202-A (U13)- actually not an EPROM, but a re-
programmable Generic Array Logic device, the Lattice #GAL20v88 in a 28 pin
square, Plastic Leaded Chip Carrier (PLCC) surface mounted to the PCB.

Special Device Packages: The actual Audio Clock Generator "module", with a full ,
module-specific ground plane on the bottom of the PCB.
This module is in a "full metal jacket" type EMI shield, which
is soldered to the PCB (possibly after the clocking
components are mounted). The module is relatively large
(~2" X 2") and has its own label, which reads:
" TimeLine Audio Clock Generator
Ultra-Low Jitter Word Clock and Oversample Clock Outputs
High Precision Programmable Sample Rate Ratio
62D027"

Micro-controller IC's: Siemens SAB 80C537-N, 8-bit CMOS microcontroller

Special Jumper Note: There is a 100 mil pin pitch "header" style 3-pin male Jumper
Block (J2) soldered to the PCB. It is PCB Print ID'd with "EDGE
SEL" The included jumper is mounted to connect pin 1 to pin 2.
Make sure this jumper is present for working units, as it is
possible that clock timing errors could occur without it.
Identity Redacted IC's: U3, U8, U9, U16 - identical 14-pin package types to the
"scrubbed" IC's on the motherboard. I therefore suspect that they
are Motorola devices.
