What are the pros and cons to putting in a 68010? I have the latest >Jameco catalog and they list several 68000 series chips. I just did this upgrade (a 68010) about a week ago. Here is what I can tell you about it. You want a 68010 chip, with a suffix of L8 ro L10 (letter may vary). This specifies the clock speed at which the chip has tested up to. For a standard b2000, the the L8 chip is plenty fast enough (the Amiga run ~7.14Mhz). The 68010 is the pin-exact replacement for the 68000. [stuff deleted about which chip to use]> >Will all the software that runs under the 68000 with >WB1.2 run with the 68010? Unfortunately, no. There is a thread on the newsgroup relating the problems people (me amoung others) have had with specific programs and with which chips. I have tried to save these messages with thehope of summerizing to the net, but only a few have made it here, where comp.sys.amiga.tech does not yet dwell :-(. At any rate, most programs DO work correctly. Also, some of the amiga luminaries on the groups (dillon, etc) have posted things about the nasty things that the Greenhills compiler did/does to AmigaDOS projects (from my limited knowledge, I believe the Greenhills compiler runs on a SUN and produces wonderfully optimized code!). >BTW I have the mechanical ability to do the swap, but I don't have the >technical knowledge of these chips. FYI the MC68010L10 is listed for $29.95. >One other chip that caught my eye was an MC68008L8, what is it? The 68008 is a 68000 in a slightly different form - it has a 8 bit data bus, which is great for those who bread-board their own - but NOT what you want to stick in your Amiga. >Thanks in advance! > John -- ================================================================== == Kurt J.
