[Question] Juko XT rom BIOS and "virtual ram"

Post by Fenix77 » Sun 02 Feb, 2020 2:07 pm


I noticed the Juko memory counter at startup has four digits instead of three, like in the rest of XT machines. But it counts 0640kb of ram as maximum.

The following question are only for emulation acuracy.


1. This emulated machine can support 1024kb?

I found specific device drivers for Juko XT machine that allows to use the extra 384kb of ram called "virtual ram". There are three device drivers. one to create a Disk Cache, other for RAM drive and the third is for print buffer.

Here are the drivers:

2. Does this machine support these drivers?

I don't know if extra information exists about this chipset and how easy or difficult can be the implementation of this feature.
