Amiga 3000 - U202, U203, U701 and U714 in production now!
« on: January 26, 2008, 05:18:34 AM »
Hello everyone,
Just to let you know that I can still make replacements for these PAL logic chips.

The replacements I make do not use the old PAL technology, they are made using the more modern GAL CMOS chips.

The GAL chips are 100% electrically compatible with the old chips but they tend to fail much less often because they produce much less heat.

If you repair this type of machines and want replacements, here is your opportunity.

If you have an Amiga 3000 and use it often, here's a great chance to update your machine and replace these 4 chips before they fail.

Thank you all!

Oops! Forgot pricing!

That's normally 8$ per chip.

A set of all 4 chips is 25$ (instead of the normal 32).

CANADIAN DOLLARS ONLY.

Shipping depends on your location.

You may as well offer GAL upgrades for A3640 v3.0/3.1 -> V3.2

If you or anyone else needs them, I can supply programmed GALs for A3640.  The one you'd most likely be after is U209 rev -03

More detail on A3640 upgrade and history here.

I can do A3000 GALs as well.  More info and contact details here.

This requires changing U209 on the A3640 which is a soldered PLCC chip.

The jedec for this chip is freely available here: http://www.thule.no/haynie/cpumods/a3640/pals/rev2/bctl.jed

I can very easily make that chip for 12$/piece. However, this replacement requires surface mount soldering/desoldering and unlike the DIP chips in the 3000, not everyone can just unplug the old/defective chips and plug in the replacement.

You wouldn't happen to have some Lattice GAL22V10-25LP chips?

I have already bought one set of these for one of my A3000's from Eslapion and was more than satisfied!!  I plan on ordering 2 more sets for my other 2 3000's.  With heat being one of the main shortfalls of this Amiga computer these cooler chips are a must have for the serious user.  You can get the newer DMAC, SCSI, RAMSEY, and BUSTER chips but until you have these you're A3000 isn't completely updated.  JMHO

I'ld like one full set for my A3000, too. Could you PM me with the necessary details (Paypalstuff, total amount to be paid, including shipping to the Netherlands)?

Tnx! :-)
Life sucks. Then you die. Then they throw mud in your face. Then you get eaten by worms. Be happy it happens in that order... My Amiga 1200
