Custom BLUE Power LED assembly for C64C

A new non-original BLUE rectangular power LED with connector for C64C
Same diffused white lens LED style as original but LED lights up blue.
Not suitable for "breadbin" C64 (which has a 5mm round LED - see below for those).
Original standard green / red C64C LED cables are listed below
Cable is approx 45cm long - so suitable for all boards

Custom Power LED cable for breadbin C64 *New BLUE LED* (includes new grommet)

Custom BLUE Power LED cable, for Breadbin C64

A new, blue Commodore 64 power LED with cable, plug and grommet for custom case jobs
For breadbin case C64 (can also be used in VIC 20)
Not suitable for the later white C64C since that uses a rectangular LED
Note: Cable is approx 45CM long so is suitable for "Breadbin" and "Aldi" model C64s)

Custom Power LED cable for breadbin C64 *New GREEN LED* (includes new grommet)

Custom GREEN Power LED for Breadbin C64

As above but with a green LED

Custom Power LED cable for breadbin C64 *New RED LED* (includes new grommet)

Custom RED Power LED for breadbin C64

As above but with a red LED.

De-solder Braid / Wick (0.5 Metres)

Ideal for assisting repair work on motherboards etc
Sold loose 0.5 Metres - ample for small jobs like for re-cap, chip replacement etc
High quality Soldamop brand braid with excellent solder draw.

Flux Pen

Helps solder flow cleanly, ideal for re-work jobs etc
Will also dissolve old flux residue etc to prepare very clean solder pads.
Non-corrosive flux.

Small Tube Of Thermally Conductive Adhesive

For attaching heatsinks to chips
5 gram tube - enough for about a dozen chips
Instructions supplied

Heatsink for 28 pin DIL Chips - Aluminium, Bare

Heatsink for 28 Pin DIL Chips - Bare

Exact size for the SID and PLA chips in the Commodore 64 which run hot are usually the first to fail.
Also suitable for the 3 C64 ROMs
Bare extruded aluminium type
Dimensions: approx 37mm x 19mm x 6mm
Attachment methods: The heatsink is not self-adhesive - it requires thermally conductive glue which I sell separately.

Heatsink for 28 pin DIL Chips - Aluminium, Self Adhesive

Heatsink for 28 Pin DIL Chips - Self Adhesive

As above but with a thermally conductive self-adhesive pad attached, ready to peel and apply.

Heatsink for 40 pin DIL Chips - Aluminium, Bare

Heatsink for 40 Pin DIL Chips - Bare

Size for the 6510 CPU, VIC-II and other 40 pin chips
Bare extruded aluminium type
Dimensions: approx 50mm x 19mm x 6mm (not suitable for the ZX Spectrum due to height)
Attachment methods: The heatsink is not self-adhesive - it requires thermally conductive glue which I sell separately.

Heatsink for 40 pin DIL Chips - Aluminium, Self Adhesive

Heatsink for 40 Pin DIL Chips - Self Adhesive

As above but with a thermally conductive self-adhesive pad attached, ready to peel and apply.

Heatsink for 40 pin DIL Chips - Black Anodized, Bare

Heatsink for 40 Pin DIL Chips - Bare

Heatsink suitable for 40 PIN Chips such as the CPU in the Commodore 64 and ULA in ZX81 and Spectrum Plus. (Note: There is not enough room for it in the rubber-keyed Spectrum unless you desolder the ULA's IC socket and fit the ULA directly onto the motherboard.)
Black anodized finish
Dimensions: 50mm x 19mm x 4.8mm
Attachment methods: The heatsink is not self-adhesive - it requires thermally conductive glue which I sell separately.

Heatsink for 40 pin DIL Chips - Black Anodized, Self Adhesive

Heatsink for 40 Pin DIL Chips - Self Adhesive

As above, but with thermally-conductive self-adhesive pad pre-attached, ready to peel and apply.

Heatsink kit 1 for "breadbin" Commodore 64

Consists of:

1 x 40 pin size bare aluminium DIL heatsinks (for 6510 CPU)
2 x 28 pin size bare aluminium DIL heatsinks (for PLA and SID)
Tube of thermally conductive adhesive
A sachet of thermal grease to renew that on VIC-II chip if desired.
Isopropyl-alcohol cleaning wipe
Instructions

Heatsink kit 1b for "breadbin" Commodore 64

As above but supplied with thermally conductive adhesive pads pre-attached to the heatsinks (instead of the tube of thermal glue) ready to peel and apply.

Heatsink kit 2 for "breadbin" Commodore 64

Consists of:

2 x 40 pin size bare aluminim DIL heatsinks (for 6510 CPU and VIC-II)
2 x 28 pin size bare aluminium DIL heatsinks (for PLA and SID)
Tube of thermally conductive adhesive
Isopropyl-alcohol cleaning wipes
Instructions

Heatsink kit 2b for "breadbin" Commodore 64

As above but supplied with thermally conductive adhesive pads pre-attached to the heatsinks (instead of the tube of thermal glue) ready to peel and apply.

Heatsink kit 3 for Commodore 64C

Although the C64C's HMOS-era chips don't run anything like as hot as the breadbin's NMOS types, the SID, VIC and CPU do get warm and (usually) no heatsinking was provided. (Note: Some versions of the C64C have a metal RF shield which does have heatsinking tabs - this can be seen through the user/cassette ports if fitted. Also, some rare early C64Cs actually have the original (wider) breadbin PCB fitted, usually marked assy no: 250466).

Pack consists of:

2 x 40-pin size bare aluminium DIL heatsinks (for 8500 CPU and 8565 VIC-II)
1 x 28-pin size bare aluminium DIL heatsinks (for 8580 SID)
Tube of thermally conductive adhesive
Isopropyl-alcohol cleaning wipes
Instructions

Heatsink kit 3b for Commodore 64C

Restore key mod capacitor

It has been found that replacing C38 with a 4.7nf capacitor improves the response of the restore key.
EG: When modded pressing RunStop+Restore should respond with the same pressure as any other key.

Small sachet of thermal grease

Suitable for renewing old, dried up thermal grease found on some versions of the C64
Note: This is thermally conductive grease, not adhesive.

3 Metres of flux-cored 60/40 tin-lead solder

TOLB Module from Eslapion - NTSC Version

A replacement for the MOS 8701 clock generator chip used on boards 250425, 250466, 250469 and the C128. Works on the C64 Reloaded too!

Onboard oscillator makes it independent from the C64 crystal and easy to convert a C64 from PAL to NTSC and inversely
Consumes only 9mA of power (a genuine MOS 8701 consumes 25-30mA)

Compatible with Commodore computers (with the PCB numbers stated above) carrying these video chips:

MOS 6567 – Original NMOS version used in most C64 sold in Japan and North America
MOS 8562 – HMOS-II version used in most C64c
MOS 8564 – VIC-II E C128 version

300+ units sold - not a single defect and not a single compatibility problem found.

TOLB Module from Eslapion - PAL Version

As above but PAL version. Compatible with Commodore computers (with the PCB numbers stated above) carrying these video chips:

MOS 6569 - Original NMOS PAL VIC-II (breadbin C64s)
MOS 8565 - HMOS PAL-VIC-II (most C64Cs)
MOS 8566 - VIC-II E PAL (C128)
