For a few months now, a replacement for the 8701 clock generator chip used on boards 250425, SX-64, 250466, 250469 and the C128 has been in preparation. Works on the C64 Reloaded too!

A prototype has now been successfully tested. I present to you The Other Little Board (or 8701 upside down...)

Pricing is 11$US or 9.20 Euros per unit. Shipping cost is the same as with PLAnkton; shipping a small packet (up to 12 units) to the US is 8$. Shipping cost for Europe is 8 Euros, Australia and South America is 10$US.

The product is strictly shipped with antistatic protective packaging. It is covered by a 90 days money back guarantee and a 3 year replacement guarantee afterwards.

NTSC and PAL versions with appropriate frequency signals are available. Both versions cost the same price.

Main features:

• - Gold plated pins
  - 3 year guarantee
  - 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)

AVAILABLE NOW for both PAL and NTSC C64 and C128 computers!!

Pricing adjusted for the current US$ vs Euros exchange rate. 10% discount now applies to both PLAnkton and GandALF.

Since I have a new oscilloscope, I wanted to give it a try on something that requires a double condition trigger.

Here's a capture of the 2 outputs from a TOLB type NTSC.
The ringing on channel 1 is because I didn't use the proximity ground pickup. In reality, both wave are very sharp square waves. The scope and probes are all 100MHz with the scope being 1.25GS/s.
