And the German manual is on TOS too.

J-f

Yes, both English versions are there. Comparing them a few days ago, with hints from Jeremy's letter, I concluded the English version from W&W was not immediately available (at least not in the US) so the guy Jeremy mentioned undertook translating it and then shared it. It is mostly accurate, but there are several typos, including in some function names, which initially made me think the functions may have changed, but I eventually concluded it was simply typos.

I thought the German manual on TOS was only for the 41CY, but I see it is for both the 41CY and RAMBOX II.

RAMBOX Manual Summary:

The German manual on TOS is for 41CY and 64K RAMBOX II
The German manual from Meindert above is for 32K RAMBOX I
The early English manual on TOS (and above) is for 32K RAMBOX I
The later English manual on TOS is for the 32K RAMBOX I
The English addition on TOS is for 41CW and 41CY (but portions also pertain to 64K RAMBOX II)

The only manual of this series that is missing is an English manual for 64K RAMBOX II, although most of that content can be gleaned from the other manuals available.

However, I am still puzzled about the extra commands for 64K RAMBOX.

The German manuals mentioned above explain the PG<>, PG01 and PG10 commands, but the ROM in my device includes these 11 commands (beyond the same 33 from the RAMBOX I set):

PG<>, PG01, PG10, PG00, PG11, ABSP, ACAXY, ACLX, CLA-, PRAXY and PRL.

Perhaps the prior owner customized this ROM adding these additional utility routines?
