Hello cbmhackers, in the past three months I wrote up a technical reference about the Commodore REU's controller chip, the CSG8726R1. The main intention of the document was to help emulation authors improving their REU compatibility. Actually I got feedback from Gideon Zweijtzer and Spiro Trikaliotis who were able to improve the REU compatibility of the 1541-Ultimate 1.1 and VICE 2.0 from early prerelease versions of the document. Bo was so nice to put an archive up to the "Funet" archive, it consists of the mastering document in OpenOffice format, the publishing format as PDF and a readme file. The whole document is covered by the GNU Free Documentation License: Look it up at: http://zimmers.net/anonftp/pub/cbm/documents/chipdata/CSG8726TechRefDoc-1.0.zip The files: CSG8726R1-TechnicalReference-1.0.pdf CSG8726R1-TechnicalReference-044.odt consist of a technical description and discussion of the hardware register interface of the Commodore RAM Expansion Unit (REU). This technical documentation tries to describe the hardware implementation aspects of the 8726R1 controller chip of the Commodore REU [8726R1] as they show up to a programmer. Sincerly yours, Womo Message was sent through the cbm-hackers mailing list
