16kb variant of the IBM 5150

The original IBM 5150 had 4 rows of 16K DRAM for 64K max on the motherboard. When the XT was released the PC was upgraded to 4 rows of 64K DAM for 256K max. I bought my IBM 5150 in March 1983. (Just before the XT came out.) The complete system (computer, floppies, monitor and printer) was $3600 and my employer reimbursed $1200. There were many third party cards available. The AST Six Pak IO/ RAM board held 384K of RAM, the old PC would then have 448K and the new PC/XT would have the magic 640K.

Is there s/o owning a 16kb variant of the 5150 or s/o who's seen it in the wild? The first motherboard of the 5150 is often referred to as the 16/64kb board. Was the 16kb variant of the 5150 without the fdd's probably a configuration never released or was ist only very uncommon? And if it was released: was it officially shiped to europe? Please do not refer to wikipedia or collector sites only stating it exists. I know that it is often mentioned, but I couldn't find any pictures. I think this variant exists, but there are so many myth on historic computer hardware out there. thanks, Martin -- Martin Peters martin.peters at news.uni-stuttgart.de
