AvailableChecked Jul 27, 2026Commodore 1541 Device ID Switcherby TheRetroChannel

6522 VIA interposer that changes a Commodore 1541 drive between device IDs 8 through 11 without cutting its original jumpers.

TheRetroChannel listed five boards in stock on Lectronz on 2026-07-27. External wiring and DIP switches are not included. A drive with a soldered 6522 first needs the chip desoldered and a socket installed; an external switch may require case cutting.

AvailableChecked Jul 30, 2026LumaFix128by e5frog

Adjustable VIC-IIe interposer intended to reduce jail bars, color stripes, and S-Video checkerboarding on a Commodore 128.

Protovision listed four units in stock at 33 EUR with a one-to-two-week delivery estimate on 2026-07-30. Shareware Plus also offered email ordering at 28 GBP plus postage on a page updated in August 2025. Installation and adjustment are not necessarily drop-in: a metal-case 128D may need the supplied additional IC socket to clear a taller nearby capacitor. Human review found no revision-specific installation sheet, so exact plastic C128D and C128DCR shield, heatsink, capacitor, and switch clearance remain unverified.

Sold outChecked Jul 30, 2026LumaTOLBby Francis Bernier

VIC-II interposer combining LumaFix video cleanup with a replacement C64 clock-generator circuit.

Protovision listed the PAL LumaTOLB at 25 EUR but temporarily unavailable with unknown delivery time on 2026-07-30. The current listing gives a three-year warranty and says the original timing chip need not be removed. Installation may require replacing the VIC-II heat shield with a larger one. A hands-on 2018 report says LumaTOLB does not work with C64 Reloaded MK2, although the separate original LumaFix does. No current NTSC order path was verified.
