I would suggest to modify it for the following

POKE("2C000","D3E4D5D69798991A1B1C9D0000000000") / power cycle

It appears that you've split main RAM into two modules by reconfiguring the F-Blocks. This is kind of like unplugging a module and plugging in different modules, but you didn't follow the rules for unplugging RAM modules, Para. 4.2.

Unconfiguring or “removing” a FRAM RAM module

1. When a RAM module is to be removed it is first converted to IRAM using the FREE PORT command. Some front-port modules, like the CMT 64K module, contained a battery that would maintain the IRAM contents. When it was later reinserted it would appear in the 71’s memory configuration as IRAM, complete with its contents. This happened to Forum member Mike in 2003 when CMT 64K module batteries still had a charge:
http://www.hpmuseum.org/cgi-sys/cgiwrap/...read=49425
Modules without a battery will lose their contents and reappear as main RAM. FRAM71/B can behave as either.
a. Battery-Backed: To unconfigure or “remove” a FRAM RAM module, first convert the module to IRAM using the FREEPORT command, then unconfigure the module by POKEing zeros into the appropriate location in the configuration string.
b. Non Battery-Backed: First, convert the module to IRAM. Determine the module’s address using MEMBUF. POKE <address>,”00000000”, which overwrites the module’s IRAM identifier, and unconfigure the module in the config string. The next time the module is configured it will be detected as unused memory and configured as RAM.

Dave

Good morning,

I hope I understand Dave's post right. Different ROM-sizes need CLAIMPORT and FREEPORT than the new POKE and therefore should be at the end of the 'whole thing'. With the FRAM71-docu, the 'Denver' presentation and the many comments I came to the following model to avoid make the SYSRAM corrupt.
Plan: JPCROM, MATHROM, 41FORTH, CURVEFIT, AMPITSTAT, DATA-ACQ, TEXT-EDITOR (or CIRCUIT) and FINANCE in the SYSTEM with the maximum amount of SYSRAM.
To configure the guest ROM (for the 64KB module too) without touching the SYSRAM. That means 144KB of SYSRAM every time (only 'loosing' possible 32KB RAM when switched to FINANCE and TEXT-EDITOR).

Am I right with this, I'm not sure about the FRAM banks, somebody a hint? Then maybe I'll start this on this weekend.

EXTENDED 1-CONFIGURATION for the DATA-ACQ 64KB module must switched to following example, 'loosing' one port? But this should'n affect the system.
For the first time installation it is necessary to CLAIMPORT 5.06 and 5.07 (free the installation for CURVFIT and AMPISTAT) FREEPORT 5.06 and ROMCOPY (with the checksum option like the doc says but this part is not clear for me, the added comments from Joe Horn says CHECKSUM is automatic)?

Switching back in the same manner: CLAIMPORT 5.06 and FREEPORT 5.06 and 5.07 then the bank-switching again.

EXTENDED 2-CONFIGURATION same for the TEXT-EDITOR (or CIRCUIT) and FINANCE module

EDIT: the other way would be to put away 32KB from SYSRAM so there is 112KB free SYSRAM in the FRAM71 and put the TEXT-EDITOR (or CIRCUIT) and the FINANCE module in there. The sum of free memory with the 16KB base RAM would be 128KB, additional the 32KB in BACKUP IRAM. Seems to be enough to and offers the possibility to do bank switching with 3*32KB modules.

DOCU: a proposal

Some practical examples one basic to learn and one intermediate:

2 or 3 more advanced examples with FRAM bank switching, with and without TOP RAM

Program for bank-switching?
