Title: A3640 PAL U209 Rev -03
Post by: alexh on July 11, 2006, 09:28:19 AM

I've done "cut-n-jumper" modifications to A3640 CPU cards this week for other people. Converting their 3.0 cards into a "half way to 3.1" cards. (At the same time fixing any Capacitor polarity issues).

I would like to provide some replacement U209-03 PALS also to convert them to true 3.2

Anyone either got some already programmed to -03, or some blank ones they could sell me programmed to -03?

At the very least can someone provide me with the A4KPALS.LHA archive (refered to in the definitive buster guide) which contains the PAL binaries?

Are these (http://www.thule.no/haynie/cpumods/a3640/pals/) any use to you ?( rev 0+2 A3640 plds from the Dave Haynie archive)

Edit:
 found a nice little collection of 3640 pld's with the help of archive.org,
 Saved them here (http://www.doobreynet.co.uk/files/3640gal.lzx), I think the one you need is part 391472.03

Ta very much.

All I need now is someone who can program them for me...

We might have a programmer here at work, I'll look around the office and see if we have any adapters.

I think they are 28-pin PLCC 22V10 PAL/GAL's? Anyone confirm?

If I make up 10 does anyone want any?

Would anyone in the UK want their 3.0 boards converted into 3.2 boards? (For a nominal fee).

I bought a PLD programmer from Ebay a while back, if you have a Chinese->UK mains adapter and can read the Chinese instructions you're welcome to borrow it ! :crazy:

The bctl.pld says it's 22V10, too. The schematics from Dave's archive reads '22V10-10'.

Depending on the price, I'd say I take one. (5-6 EUR?)

Segor Germany charges 9 EUR :-o for the first and 2 EUR for subsequent programs - their prices had been very fair but went up some time ago.
