Hi.

Do you have any of these left? Are they drop in replacements for the existing 64 kernal / basic rom / 1541 ROM?

I can program them myself - have a suitable programmer.

Thanks,
 
Yes I have some 27HC641 to sell.
Remember that to program this chip your programmer has to be able to do it (check that "27HC641" is into "devices list" of your programmer) and you have to program them swapping 3 address line ( then the product will be a 2364 pin compatible).

If you have the .BIN files I can program them for you
 
Hi there,

Are you able to do a drop in replacement for:

1541 roms

325302-01
901229-05

Shipped to Australia?
 
Yes, it's possible,
but unfortunately the shipping costs for Australia are high:
€ 13.50 tracked
€ 6.50 not tracked (I will not be responsible for the outcome of the shipment)

Thanks for getting back to me :)

Postage is a bit cost prohibitive. I'll keep looking for a parts drive locally, but if nothing turns up I'll hit you up.
 
I am aware of the high shipping costs from Italy, I hope you can easily find the components you need to bring your 1541 back to life!

27HC641 EPROM,if specifically programmed, are pin compatible with 2364 ROM.

This Eprom can replace the old Commodore 8K ROM in VIC20, C64, SX64, 1541, many game cartridges,ecc....
A lot of Commodore computers, drivers, cartridges use the 2364 ROM!

The only differences between 2364 and 27HC641 are 3 address pins swapped, consequently it have to be programmed through a converter-socket (into pic) OR it has to be programmed with a manipulated ".BIN" file that exchange the address pins.

Normally this device is NOT programmable with a cheap universal programmer,
so I can program it (correctly) for you.

Price (without PPfees and sending):
5€/pcs unprogrammed,
20€x 5pcs unprogrammed

(ask for programming service)
Minimum order: 10€+ shipping + PPfees

Also on sale elsewhere.
