Found this in its nice HP parts bag while cleaning up another bench, this new (E)PROM is for the hp 4951 presumably (early protocol analyzer), and has a 1986 date code.? Might be too old to still be good, but then again, maybe you can read and re-burn it..Free to anyone that can make use of it, just needs US$8 for an airmail padded bag in north america.
all the best, walter (walter2 -at- sphere .bc.ca) sphere research corp. https://www.sphere.bc.ca/test/stuffday.html |
开云体育Walter, ? I don’t need it but I can read and archive the files or send the files to anyone that needs it.? Terrible shame to let it go ‘uninvestigated’. ? What is the ‘chip’ or the part number? ? Happy to help if I can. ? Joe ? From: [email protected] [mailto:[email protected]] On Behalf Of walter shawlee ?

开云体育Sorry to reply to my own email, but, obviously, I didn’t pay attention to the Subject Line.? Duh!!? ? You’ve given me the part number but all the ‘cross references’ I have for HP fail to tell me what the ‘chip’ is. ? Thanks. ? Joe ? From: [email protected] [mailto:[email protected]] On Behalf Of J.

According to the 4951A Service Manual the 04951-10002 part is A2 U103. The A2 schematic shows U103 has a standard 27256 EPROM pinout. 04951-90002_4951A_ServiceManual_209pages_Apr84.pdf |
开云体育Glen, ? Thanks for the ‘ID’.? I can certainly read, archive, post and/or distribute the contents of a 27256. ? I looked for a manual for the unit but I did not think to look at hpmuseum. ?
