ETI-673 Multiprom Test tapes and programs - ChickenMan - 24-08-2024
Thanks to greybeard for making this tape recording available. Recorded at 48khz and saved as 16bit WAV files. The 4 individual programs were extracted, noise filters applied and they then successfully loaded into a PC85 Microbee error free. The files were than saved out as individual programs.
The ETI-673 project design by F. M. Capmeil, presented with the
co-operation of Avtek Electronics, permits extending the ROM
capacity of the Microbee to 44K, or to 308K total by
daisy-chaining up to six slave boards to produce a sort-of high
speed 'read-only virtual disk' (a ROD?). It takes 2532 or 2764
roms (can be mixed) and, in addition, provides 11 open-collector
outputs and eight buffered inputs.
ETI-673 was published in the ETI November 1983 edition and intended for the early ROM based Microbees. This article is in the Microbee/Public/Magazine/ETI/ folder as rom_interface_board_eti_83_11.pdf. We also have the Manual from Avtek in the Microbee/Documentation/Manuals/Hardware folder as avtek_multiprom_interface_manual.pdf with further information including a Menu listing.
The files extracted were the Multiprom Interface Test Program Real Time I/O Monitor in both Basic and BEE forms as well as the EDASM source code. There was also a general Multiprom Test program in Basic. The WAV files were also down sampled to 24khz to reduce their size but retain error free loading still.
So in the MbeeTech Repository in the Microbee/Software/Tapes/Original folder we placed -
multiprom_test_programs.zip <-- which contains all these following files
biomon.wav & biomon.mwb
biomonm.wav & biomonm.bee
bdmon_edasm.wav & bdmon.edt
biotest.wav & biotest.mwb
