Hello
The xt-386 class hobby still ongoing, and today I did get my Inboard 386/pc to run an Intel 486 cpu.
I used a "Transcomputer" converter and a few socket extensions. Did buy two used converters, made for IBM microchannel and for Compaq, and they both seems to work. I did not buy the NIB version , so a lack the floppy disc and the manual's.
(photo from above - Transcomputer module,socket extension and Inboard )
The speed is relativ to the clock speed of 16 Mhz - reasonable, and the two modules seems to have the same speed results. Have to test with other CPU's but a quick test with Evergreen 586 did not start at all. Cyrix 486 and Intel 486dx did start like expected.
BUT this cpu modification draws alot of heat - and a do not dare to mount the chassicscover, it is like heavy heat exhaust.
My windows 3 did not start - have to look into it, or try with a new windows installation. DOS, drivers,NC commmander and Checkit did run like expected.
And yes, did only get it working hours ago, and perhaps some "funny" obstacles lay ahead .
