p.15 PDP-1802—Hardware Simulator in Assembly Language (p.241 in reprint volume 7)

[author : Christopher L. Hamlin]

This author chose to execute PDP-8 machine-language programs on a COSMAC 1802. This first of two articles describes the PDP-8 instruction set and front panel functions, and an octal console monitor for the 1802.

p.22 Multi-68000s in a Personal System (p.244 in reprint volume 7)

[author : Al Kossow]

If real-time rotation of graphic images sounds good to you then this project, which also supports multi-tasking and several kinds of mass storage, should appeal. Long live homebrew!

p.26 An Improved LET Processor for LLL Basic (p.248 in reprint volume 7)

p.26 An Improved LET Processor for LLL Basic (p.248 in reprint volume 7)

[author : Norman E. Thagard and George Glenn]

The version of Basic widely distributed in earlier years by Lawrence Livermore Lab has an assignment statement which is quite limited. The authors applied compiler theory loosely to this interpreter to come up with a much better LET.

p.36 A Print Utility for CP/M (p.256 in reprint volume 7)

p.36 A Print Utility for CP/M (p.256 in reprint volume 7)

[author : Dan Daetwyler]

Tired of seeing wasted printer paper? Would you rather batch your printing jobs than set up SUBMIT files? How about another good use of the ambiguous file name? This utility addresses all these; perhaps you will find ways to make it even more useful.

p.50 A Cross-Reference Generator in C (p.266 in reprint volume 7)

p.50 A Cross-Reference Generator in C (p.266 in reprint volume 7)

[author : Jeffrey L. Taylor]

Software conversion is one process which makes you wish you had a cross- reference listing. This one is written for Whitesmith’s C compiler and Portable C library, but the author has included aids for adapting it to other compilers and libraries.
