A question re go71

[rprosperi]

Bought, installed and configured go71b; if careful, I can use the buttons without much problem on my phone.

I was able to create and configure RAM modules and install/remove the built-in ROMs with no issues; overall, an amazingly accurate emulation of the 71B, I am impressed.

But I have found some problems, can anyone confirm these?

I. If you create an IRAM (add RAM module per steps shown above, then FREE PORT(x) to make it IRAM) but never copy any files to it, shutting off the emulation ([f] [ON]) and turning back on will reclaim that port back into main RAM. However if you have copied a file to the IRAM, it is preserved during a power cycle, and thereafter the IRAM is preserved during power-cycle even if empty, as long as something has previously been copied there.

II. I was able to import and install a rom image, however I cannot now remove it. I copied JPCF05.ROM (renamed from .BIN) to the appropriate Android folder, then installed with no issues. I installed it into Port-3 and could see it in VER$. However I cannot remove it. This is what I did:

a. Power-off emulation
b. Touch LCD to open configuration
c. Touch ROMs
d. Touch Port-3
e. Touch "Port 3 contents" => Choose Action list opens
f. Touch Remove Chip => See msg "No chip in port" even though the JPCF05.ROM file is visibly present on the left side.
g. BACK to return to emulation
h. Power on
i. VER$ no longer shows ROM info, implying it is not installed
j. Power-off emulation
k. Touch LCD to open configuration again
l. Touch ROMs
m. Touch Port-3 (see the rom is still installed, i.e. listed on the left)
n. Press 3 dots (android options menu) => menu appears at bottom
o. Touch Delete => see "Choose Rom to delete" list
p. Touch JPCF05.ROM => see msg "JPCF05.ROM is in use!"

So some portion of jpc71b still believes the external ROM file is still being used, even though the 71B emulation itself does not 'see' the ROM.

Additional observations:

1. I can still tap the built-in "JPC" button at the top, and it does install that ROM which then works OK. But returning to the config screen shows BOTH roms (the built-in jpcrom and the previously imported JPCF05.ROM image) installed. The installed image still cannot be removed from here.

2. From the configure screen press Add ROM opens the list to choose, however the list has no items listed, even though I've confirmed the file is still in the proper folder.

3. Even causing a MEM LOST does not release the JPCF05.rom file.

Possible reasons (pure speculation):

A. Maybe Port-3 is reserved for the built-in jpcrom image?

B. Maybe the JPCF05.ROM image is troublesome since it installs several poll handlers and also hooks into the HP-IL message table.

C. Bugs in go71b? (But I'd like to have someone confirm them before reporting them as bugs to Olivier)

Thanks
