HP 71B Service Manual Message #1 Posted by Dave Frederickson on 21 Apr 2008, 7:09 p.m. Does anyone have a copy of the 71B Service Manual?

Re: HP 71B Service Manual Message #2 Posted by Raymond Del Tondo on 22 Apr 2008, 12:30 a.m., in response to message #1 by Dave Frederickson It's not called 'Service Manual' directly, but the HP-71B IDS (Internal Design Specification) , and also the Hardware IDS from the hpmuseum DVD could be of help.

Re: HP 71B Service Manual - Service Rom? Message #4 Posted by PeterP on 22 Apr 2008, 12:19 p.m., in response to message #3 by Etienne Victoria Etienne, Thanks for the link, very useful! One question, does anyone have the service ROM for the 71b that is mentioned in the manual? I have a CMT eprom burner and would love to burn an image on on of my modules... Cheers Peter

Re: HP 71B Service Manual - Service Rom? Message #5 Posted by Eric Smith on 22 Apr 2008, 2:54 p.m., in response to message #4 by PeterP Won't work, unfortunately. The service ROM is a fix-address "takeover" ROM, and the CMT EPROM modules only support dynamic addressing.

Anyhow, is the Diag ROM image available elsewhere, any-where? Just to give it a go with some up to date technology... ;-)) Cheers. Diego

Let me know if I can be of any help in this endeavor Diego (if we can locate a service rom...) - purchasing agent, shipping clerk, suitcase carrier (well, maybe not the last one...) Cheers peter

Re: HP 71B Service Manual - Service Rom? Message #9 Posted by J-F Garnier on 23 Apr 2008, 3:37 p.m., in response to message #8 by PeterP Have a look at this old thread, the Diag ROM exists! Actually Jan Buitenhuis was so kind to give me (Thanks again, Jan, if you are still around) one of his Diag module, and I was able to extract the ROM content (16kb) despite the difficulties due to the take-over nature of the module. The Diag Rom doesn't run inside Emu71, because my emulator doesn't simulate all the hardware details, so until we have a 'Clonix71', the Diag Rom image is useless.... J-F
