Way to test Rambo XL 256k Memory upgrade? And Q about file conversions

[thomas3120]

Hello,

Wondering if there was a small basic program or something I can load through my S-drive MAX that tests the Rambo XL memory?

 

Also, Is there a PC utility to convert Atari 8bit files such as .com, .rom to .XEX or other file extensions?

thanks,

just rename .com files to .XEX is all that's required

im not aware of a basic program but these 2 are commonly used:

XRAM021.COMSHORTEST.COM

 

you can use altirra to add them to a bootable .atr disk image to load on the SdriveMAX

here ya go:

DOS_v2.5_1984_Atari.atr

altho xram.com doesnt seem to work on the emulator, hope it does for you

I seem to remember a caveat about XRam and a Rambo 256k upgrade... IIRC, I think the first bank of extended memory would show a problem even when one didn't exist.  Now this makes me want to pull out a Rambo 800XL and test...  I will.

 

 

See?

Yes... don't use Satantronic's XRAM tester 0.21.0 - it was updated in 2019 To 0.22.0 specifically to not erroneously detect the 4 banks that mirror the base 64K in a RAMBO type 256K upgrade:

0.22.0 looks like this on a RAMBO 256K XL - note nothing on $8x row:
