Hello together,
I replaced the ROMUPL28.ZIP archive for fast upload of a HP28C Rev. 1CC ROM image by the CPROMUPL.ZIP archive on my homepage at http://privat.swol.de/ChristophGiesselink/ in the Emu28 emulator section.
The new archive contain information about fast upload on
- HP17B (english or international) ROM Rev. B
- HP17BII (english or international) ROM Rev. B
- HP27S ROM Rev. A or B
- HP28C ROM Rev. 1BB or 1CC
- HP28S ROM Rev. 2BB
- HP42S ROM Rev. A, B or C
In all cases a HP48 is used as receiver. The HP48 must have between ~70KB and ~135KB of free merged RAM. The exact size depends on the ROM image you want to upload.
Dowloaded image size = Size of ROM * (132/128) + 5 bytes string object
Example HP28 Image (128KB):
128 * 1024 * 132 / 128 + 5 = 135173 bytes (~132KB)
+ several extra bytes for the capture program and runtime information.
The complete upload process for each ROM image takes always less than 1 hour.
Regards,
Christoph
