Title: On-board socket occupied - how to add else one ROM?
Post by: MIRKOSOFT on January 29, 2011, 11:45 PM

...in my internal socket of C128DCR is BASIC 8.0 & GEOS 128 2.0 ROM with switcher.

I have on flat C128 Turbo Assembler 128 ROM, but I want to integrate both to the C128DCR.

So, I know about Internal/External ROM - now where to place TASM128 if is on-board socket occupied?

I have also 1764 REU 1,5MB - is there socket for external ROM? Or how to do it to use both?

Many thanks for help.

Yes, there is an empty socket in a 17xx ram expander.

Thank you Robert!

Here's the main Q:

How to activate this ROM in REU socket?

'cause onboard I have BASIC8 & GEOS128 - and activating is by holding CONTROL during startup/reset.

And Turbo Assembler 128 has the same activation - holding CONTROL...
?

Thank you very much.

Ah, that I don't know. That being said, I will look in the documentation of the KeyDOS ROM v2 and see how it was used in the socket of a 17xx ram expander.
