HP-71B and some (to me) interesting modules

[J-F Garnier]

A really great HP-71B system sample!
The only obvious missing item is the MATH ROM, and at your option the JPCROM too.
With all the available memory, you will have no problem to load them.

In the SHOW PORT output, it shows a 16KB ROM (or EPROM) which you list as being a 64K RAM module, and also 32K RAM in ports 4.00 and 4.01, which would have to be the 64KB RAM module. I assume these two modules were swapped between you initial SHOW PORT and later description, is that the case?

The 16KB ROM is probably the FORTH/Assembler ROM.
Here is my understanding on the SHOW PORT Output:
0.05 16384 2 : HP-IL
1 16384 2 : FORTH
2 65536 2 : 64K EPROM
3 32768 2 : 32K EPROM
0 4096 0, 0.01 4096 0, 0.02 4096 0, 0.03 4096 0 : internal 16K RAM (4x4KB)
4 32768 0, 4.01 32768 0 : 64K RAM (always set as 2x32K)
5 32768 0, 5.01 32768 0, 5.02 32768 0, 5.03 32768 0 : 128K RAM (4x32k)

Quote:OTOH, the module in Port-3 looks quite interesting with several new looking LEX files.

I suspect that the WUWROM1L and KABULEX LEXs are compilations of existing LEXs, plus maybe specific support LEXs.
The VER$ response:
HP71:2CDCC HPIL:1B FTH:1A EDT:A KBD:B W&W:A CSTU:A CSTU:A EDT:A DATA:B
shows a specific W&W LEX, plus 2 times the CSTU (I guess the well-known CUSTRGLX LEXs) and the DATA:B seems familiar to me too.
Note that EDT:A is duplicated too, meaning the EDLEX, already present in the FORTH ROM, is duplicated in one of the LEXs of the 32K EPROM, together with the EDTEXT and EDKEYS files.

Jan, you may want to reprogram (after properly saving their contents) the EPROM modules with more interesting material for you, all you need is to find someone near you, owning the programming tools, to do it for you :-)
