I finally upgraded some discs from my PC-FX full set:
Super PC Engine Fan Deluxe Vol. 1 & 2
(the last photo shows what I had before, just the discs and inserts that someone else had cut out of the mooks)

Ah, the set is great, I just had to buy it. However, I can't remember ever having used it seriously...

Replaced the laser sledge and cleaned and greased the CDM. The focus error is now gone and the discs are reading perfectly again. As a finishing touch, I added a drop of UV lacquer to the spindle.

Reworked the Timekeeper with the PCB by @cabridiy.bsky.social and thoroughly cleaned and greased the tray loader. The CDM has not been touched yet, but appears to be defective. The repair is a story for another day...

On closer inspection, the Grundig CDI 110E mainboard appears to have been converted from a Mono IV NTSC mainboard with an RF modulator. The soldering is somewhat rough.

It didn't come with a DVC, but with something much better: a DVC eject mechanism that I've never seen before.

New family member: Grundig CDI 110E (470/82? – it has a brandless OEM ROM like the TaliLaser 2000)

Nintendo Family BASIC (HVC-BS) and Keyboard (HVC-007): The condition is not too bad; it seems to have seen little use. Unfortunately, some of the paperwork and labels have mould measles.

Ultrasonic knife vs. Timekeeper MK48T08B
(Warning: high-pitched sounds).

Only the final cuts are shown. Before that, the top hat (and unfortunately also the chip) was cut for about 2 minutes.
This is only a test to see how efficiently the Timekeeper can be cut apart.
