    You can find the schematic for the original 5150 in the PC Tech reference manual over on Minus Zero Degrees.

    I don't know what you used for a search engine but Google for "IBM 5150 Schematic" gets you a whole potload of hits

    The people over at MTM have explicitly said that they used the 5150 Tech Ref as their basis.

    But I don't know what good this will do you, as the MTM boards have been sold out for quite some time.

    I just happen to have the schematics of the 5160 in Eagle, although not complete: it only has two slots instead of the original five. Just blame my laziness. No board. It isn't a 5150 but if you really want a 5150, to change this SCH is easier than to start from scratch. Just send me a PM using the email address found on my site then I can send it to you from home. In that case I also can add some schematics of some clones that include a turbo mode.

    And may I point you to an older project of Sergey: the XI8088. It also has turbo but uses SRAM instead of DRAM and using EEPROM instead of EPROM; some nice ideas to use yourself.

    Question: why a 5150 and not a 5160, because that is the only case you have?

    The 5150 board (PCB) seems to be still available at http://www.mtmscientific.com/pc-retro.html for $39.50 shipped to US.

    Hmmm, just popped up: what about a board that fits into an ATX-case? Just an idea

    More or less, yes. To be honest, I was thinking about a board with only standard ICs. My reason: the chance that they are available is much higher then any 'old' ASIC or other type of custom IC. But that is a personal choice.

    But using the hole reserved for the connectors for a CF card is a very good idea!
