GandALF, sub for 1541 custom IC MOS 325572-01

Postby eslapion » Sat Jul 29, 2017 10:23 pm

GandALF is a replacement module for the MOS 325572-01 custom IC installed in all VIC-1541 and 1541 disk drives that use the mid sized boards (1540050, 250442 and 250446).

The Gate and Array Logic for Floppy is about the only component on the electronics board of the standard 1541 and the later VIC-1541 for which there is no current version or cross reference on modern components list.

Using technology similar to what's used on PLAnkton, me, e5frog (Fredric Blaholtz) and electrical engineer Sylvain Brisebois were able to create a fully functional and perfectly compatible module to replace this IC which is specific to the 1541 series of floppy disk drives and only ever made by MOS or the Commodore Semiconductor Group.

No other company or individual has ever previously offered a compatible or equivalent replacement component.

The price is 19.50 Euros or 23$US per unit. GandALF is now in full production and available!
Customers ordering 10 units or more get a 25% discount. Customers ordering 5 units or more get a 20% discount.
Add one or more TOLB to your order and get 10% discount (when ordering less than 5 units) , that's 17.55 Euros or 20.70$US per unit!

Shipping a small packet (up to 8 units) to the US is 7$. Shipping cost for Australia and South America is 9$US, Europe is 8 Euros.
Purchase some of my other products, TOLB or PLAnkton, and I will combine shipping to save you money.

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.

That is truely a work of art ...
I'll have to dig out my 2 x 1541s and check em over to see if they are needing anything..
btw ...I take it this would not work in a 1540 ?

Nope. The 1540 does the same job using about a dozen discreet logic chips.
