Title: A4000-CR
Post by: raketa on August 11, 2007, 01:14:00 PM

Hi, I just bought an A4000-CR mobo, but it does not have soldered CPU. Is it possible?

Does it work?  I have a A4000-CR mobo and it has a 68030 & 68882 on board!

No, it doesn't work. Only with a CPU card. But it doesn't seem to be desoldered.

Well its still a CR board even if the CPU has been removed.. but yeah there should be an 030 sat there, maybe it failed and they removed it? (removing QFP chips is easy, soldering them on is less so)

yep there are A4000CR without any CPU/quartz on mobo.

ah .. and any accelerator card using INT clock source, will not work.

well, perhaps installing a 50 Mhz quartz! never tried personally but it should works.

Amiga Hardware Database has info and it says that your mobo came with a A3640 with 68LC040 installed and did not have the 68EC030 soldered on the mobo.
