I'm now balancing in The Ace for users with SuperCPU and Mega 65 users - something like MRS - Memory Resident System, or RAMOS... So, Qs are really from this.

Well, not really sure exactly how or what you are trying to do, but bear in mind if you use U36 you will only have 1/2MHZ access to the ROM's whereas if you keep the ROMs on the superCPU bus you will have a much faster system (provided your routines are going to be used quite often). Perhaps use U36 as bootstrap code and re vectoring of the C= ROMs and all the Kernal routines into the faster bus ROM chips. If you had the device on the cart port it would make the boot system easier.

Here we understand us not: Idea is to load all components into SuperRAM and leave working area 128K Commodore 128 base RAM for applications not inside OS natively. In case of Mega 65 - this computer (currently in FPGA) allows to addressing 256 MB RAM - it's more than 16 MB of SCPU, original C65 has 128K RAM, so working base is same. No matter - both sizes are able to load whole OS, but problem is booting time... but this is off topic
Using SCPU ROM is bit another - we all know that handy solution can be read directory of CP/M disk outside CP/M - by simple SYS command like: SYS 55000,8 - example reads directory in drive 8... and other missing features of C128.

I don't know how that appears on the screen. Do you have a screenshot of the C128 System Information? Truly, Robert Bernardo Fresno Commodore User Group www.dickestel.com/fcug.htm
