Research on Myarc Extended Basic II
UPDATE: 2020/07/02 07:05 UTC
This thread shall be used for documenting research on Myarc Extended Basic II.
Purpose
Create a version that can be used with SAMS and a RAM cartridge (superspace)
Target modern storage devices like CF7+/Nanopeb, TIPI or HRD4000B.
No longer rely on the unobtainable MEMEXP-1 128K/512K memory expansion.
Recreate assembly source code
Research originated on discussions found here:
Yesterday evening I downloaded as much information as I could find on the TI-99/8 armadillo Basic (XB II).
There are actually quite a few documents floating around, created during a 2 years’ period (1982-1984)
?/??/?? - 99/8 Basic / EXT. Basic interface specification
?/??/?? - 99/8 Armadillo Basic specification
?/??/?? - VDP RAM usage in Armadillo Basic
5/26/82 - 99/8 The mapper and us
9/30/82 - Armadillo Basic internal design
3/23/83 - 99/8 Mapper
