[Premium-Rx] (I) WJ-8718 Remote and MFP; (II) Uploading

[Raymond Boute]

Dear WJ-8718A enthusiasts (and others),

(I) Thanks to all who responded to my previous enquiry about the 
7-segment displays, in particular Jay  who, despite his many other 
activities, provided effective assistance.

It seems I still need some help for the following miniprojects.
(a) First priority: establish remote control.
(b) Second priority: obtain an MFP front panel assembly.

Some background information.
    The unit in question has an ordinary (non-MFP) front panel, but 
inside it fully matches an MFP unit (Fig. 5-3 in the  Instruction 
Supplement for WJ-8718A/MFP).
    In particular, instead of the basic WJ-8718A cards type A6A1 
(791575-x Up/Dn Count) and A6A2 (791591 FP Interconnect) it has an 
MFP-A3 (794308 IF Interface) and an MFP-A4 (794274-1 Synthesizer 
Interface and Memory; in fact, the MPU card).
    It also has a 488M-A3 (796075 IEEE 488 Interface) - although I 
much prefer RS232 for simplicity.

Questions
Ad (a). Problem: the 488 interface is totally unresponsive.

Q1: Given that the front panel has no "remote" button, can remote 
control be established from outside?

Q2: Might it be that the 794274-1 contains the wrong 
firmware?  Terry's Part Number Index suggests it should be 794275-3 
for M488-2 (what's the 2 here?).  On the other hand, a paper label on 
U1 is marked 488/841142/V1.84.  U2 and U17 are absent, and are marked 
as N/U (for all versions) in the table next to the schematics.

Q3: If the answer to Q2 is affirmative, where could I find the proper 
cards?  Otherwise, how should I start debugging?

Q4: Although I intend writing my own SW, does anyone have software to 
start (e.g., WJ RCS)?

Ad (b) Where can I find a WJ-2718A-MFP front panel 
assembly?  Belatedly I saw a recent offer on eBay.

(II) The TOCs in the WJ manuals seem rather lengthy and dispersed, 
requiring considerable leafing-through. Therefore I invested a little 
time in making a convenient 1-page synoptic table.  If this might 
help other people, I can upload an example (where?).  I am also 
prepared to make customized instances on request (free, of course).
