Yes, please post the dumps if possible. It's always interesting to explore. The Pod diag and Pod proto may be already known from Raan's archives, or they may be different versions. The DINGO ROM is al

It is an inductor, that seems to be Dominique's version of the EMI filter (see Service Manual p.2-11). I don't know the value, but frankly Idon't think it's a good idea to add an inductance in the pow

Thanks for confirming, because I have no system right now to check it. Actually, the fix was easy: the XIL code was just disabled by mistake. A single-line fix was enough :-) I'm very pleased that the

Actually, there is an alternate (not better) scan, see https://archived.hpcalc.org/museumforum/thread-182720-post-182720.html (it took me some time to find out from where I got the different scan I ha

Ok, the problem is your ASSIGN IO statement. What you did is to assign code ':VM' to the first HP-IL device which is the Emu75 display. Since you have the I/O ROM loaded, you may better use the assign

I didn't remember that there was a buffer board in the connector! Indeed, the PMS Service manual mentions the buffer board, and there should be a sheet 7-3 as mentioned on page 7-1. I was in touch wit

If you succeeded to make Emu71 communicate to the HP3468 with Win98, that's already good news! The HP-75 HP-IL commands are similar to the HP-71B but the setup is a bit different. To make Emu75 comfor

Many thanks for these documents. Indeed, the BASIC LANGUAGE ERS (Chapter 1) , MAR., 1981 says: "...an effort has been made to conform to SERIES-80 BASIC's" and introduces many new ANSI-style keywords,

Also: SQRT - SQR LOG - LN Note that the 71B went further than the ANSI standard draft with the ATAN or SQRT keywords I believe it was to provide a natural transition path for HP-41C users - the HP-41C

Thanks for the explanations and details, Eric. The two pages on HP-IL mainly describe the RIO/WIO statements, that were NOT included in the final HP-75 ROM (was ROM full?). This may explain why this d

Yes, all documents related to the HP BASIC origins and variants are of great interest to me ! J-F

Actually not, the ERS dated 9/06/81 seems complete with sections 1 to 11 plus appendix A to D up to page 79 of the pdf. However, it is followed by a few pages of section 4 of an earlier version dated

You maybe noticed a document called "Kangaroo Software ERS" recently published on hpcalc.org : https://literature.hpcalc.org/items/2179 It is a user-level specification of the HP-75 firmware, and so d

in Emu75, I implemented the BCD operations with a simple code, inspired by my Coconut (HP-41) simulation: e.g. for addition of two BCD nibbles: binary add the 2 nibbles, if the result is greater than

You can use the Diagnostic ROM for the HP-75. It allowed me to find a minor bug in my Capricorn simulation. The ROM is available in the file section of the group.io , in the 75 Application (plug-in) R

Another example of change in the BASIC syntax in the HP-75, relatively to the Series 80: The Series 80 is using the DEG and RAD keywords to set the angle mode used by trig functions. But the HP-75 is

Bob, I know there are MANY improvements between the HP-75/Series80 and the HP-71B :-) BTW, the labels were already available in the HP-86/87. To be more specific, I'm looking at changes that break the
