Hi all,
maybe someone here is interested in the FOSBIC (FORTRAN Simulated BASIC
Interpretive Compiler) system.
Background: This was developed, oder rather ported from UWBIC (University of
Washington, Prog. W.H. Sharpe) in the mid 70s, by Prof Weber et al. at the
German University of Gießen, for
Hi all,
The PDF at
https://www.bitsavers.org/pdf/intel/insite/1983_Insite_Users_Program_Library_Catalog.pdf
lists various old user submitted software which could have been ordered

Is there anything of that archived and downloadable somewhere?
Regards

You might look up Nick Tredennick's book "Microprocessor Logic Design:
The Flowchart Method" which is sold at Amazon for an obscene price - but
maybe some university library has a copy. It's focus is on a methodology
for designing microcode, and it uses the design of the single chip 370

It may, in fact, be possible - with custom ROMs - to use the 1541 for other
