Interesting ICL 1900 info here:
http://www.fcs.eu.com/icl1900/index.html
Thank you for this link - seems as if more survives than I had feared ...
perhaps even time to think again about a project to build a 1900 on a FPGA
( I have some fairly detailed documents on the internals of the 1905 CPU -
the implicit wired-or usage in the arithmetic unit will cause some
translation
difficulties when transferring to modern logic styles, but looks
plausible.)
