HP 8904A Firmware EPROM image 08904-87010
« on: March 07, 2020, 05:33:43 am »
I'm looking for an HP 8904A firmware image from A2U12 with label 08904-87010.  I currently have firmware 08904-87007 (the EPROM is AM27256), and have issues with HP-IB stalling after a number of commands are sent.  As per HP's service manual page 7-2, this is a known issue that is resolved by upgrading to 08904-87010.  An image of the newest firmware (08904-87011) is available online, however this is incompatible with hardware having a serial number prefix below 2948A.

There is also an EPROM in A2U13 labeled 08904-87008, but this part does not need upgrading (per page 7-9).  I can post binary dumps of both if anyone is interested.
