I wonder if anybody has a Voyager chronology with such details as dates of all TCMs or precise times of closest approach to different moons of Jupiter back in 1979. What I've found of pre-Saturn TCMs is here:

Voyager 1

1977.09.05 Launch
1977.09.11 TCM-1
1977.09.13 TCM-1
1977.10.29 TCM-1A
1978.06? TCM-2?
1979.01.04 Jupiter Observatory Phase
1979.01.29? TCM-3
1979.02.21 TCM-4
1979.03.05 Jupiter Flyby
1979.04.09 TCM-5
...
1980.08.22 Saturn Observatory Phase
1980.10.10-11 TCM A8
1980.11.06 TCM A9
1980.11.12 Saturn Flyby

Voyager 2

1977.08.20 Launch
1977.10.11 TCM-1
1978.05.03 TCM-2
1979.04.24 Jupiter Observatory Phase
1979.06.27 TCM?
1979.07.09 Jupiter Flyby
1979.07.09 TCM?
1979.07.23 TCM?
1980? TCM B6?
1981.02.26 TCM B7
1981.06.05 Saturn Observatory Phase
1981.07.19 TCM B8
1981.08.18 TCM B9
1981.08.26 Saturn Flyby

Again I was able to extract Voyager 2 Saturn visit times from the article by Campbell, Jacobson et al.

Date and time, UTC SCET -- Time from Saturn CA -- Event -- Distance, km
1981.08.23 01:26:56.5 -03 01:57:11 Iapetus 909070
1981.08.25 01:25:25.8 -01 01:58:42 Hyperion 470840
1981.08.25 09:37:46.3 -00 17:46:21 Titan 665960
1981.08.25 22:57:33.2 -00 04:26:35 SXII Helene (1980 S6) 318200
1981.08.26 01:04:31.8 -00 02:19:36 Dione 502250
1981.08.26 02:22:16.8 -00 01:01:51 SXIV Calypso (1980 S25) 153518
1981.08.26 02:34:26.X -00 00:49:41 Mimas 309990
1981.08.26 03:08:29.4 -00 00:15:38 SXVII Prometheus (1980 S28) 287170
1981.08.26 03:19:17.5 -00 00:04:50 SXV Pandora (1980 S26) 107000
1981.08.26 03:24:07.8 00 00:00:00 Saturn
1981.08.26 03:33:02.4 +00 00:08:55 SXVI Atlas (1980 S27) 246590
1981.08.26 03:45:16.1 +00 00:21:08 Enceladus 87140
1981.08.26 03:50:03.6 +00 00:25:56 SX Janus (1980 S1) 222760
1981.08.26 04:00:24.6 +00 00:36:17 Earth occult enter Saturn? 166133
1981.08.26 04:05:55.8 +00 00:41:48 SXI Epimetheus (1980 S3) 147010
1981.08.26 04:08:12.1 +00 00:44:04 Sun (umbra) occult enter Saturn
1981.08.26 05:34:36.9 +00 02:10:29 Earth occult leave Saturn 215762
1981.08.26 05:44:56.s +00 02:20:21 Sun (umbra) occult leave Saturn 223334
1981.08.26 06:02:46.7 +00 02:38:39 SXIII Telesto (1980 S13) 284400
1981.08.26 06:12:30.2 +00 02:48:22 Tethys 93000
1981.08.26 06:28:48.4 +00 03:04:41 Rhea 645280
1981.09.05 01:22:33.5 +09 21:58:26 Phoebe 2073640

Notes:
1. Two or more lines for rings crossing were not discernible.
2. Numbers cross-checked against the Saturn CA time.
3. Current names an designations for small satellite discovered in 1979-1980 are used.
4. Don't know why this distance to Phoebe was there in the table.
5. Current estimate for Saturn CA seems to be 03:24:05.
