These files were transcribed by James Fehlinger of New Jersey, US in

B65SIM.alg_m
|
|
A simulator for the Burroughs B6500 written in a variant of B5500
|
|
Extended Algol, termed LONGALG. This variant implement a "Long
|
|
Array" type, which appeared to the programmer to be a single-
|
|
dimensional array, but was implemented as a two-dimensional array.
|
|
The compiler generated code to partition the array index into column
|
|
and row portions, and index the row and column accordingly.
|
|
|
|
B65ESPOL.alg_m
|
|
An early implementation of an ESPOL cross-compiler for the B6500,
|
|
written to run on the B5500. We believe that Don Lyle was the
|
|
principle implementor of this compiler.
|
|
|
|
B65MCP-MARK00.esp_m
|
|
A very preliminary version of the B6500 MCP. It is notable for its
|
|
use of ESPOL Queue structures, which eventually proved to be too
|
|
expensive at run time, and were removed in the Mark II.0 release.
