Re: [patch] Systems from the first Olivetti PCS series

Just a curiosity that I've forgot to mention before: PCS 386 SX BIOS has some kind of built in debugger.

Maybe accessed by a key combination but I don't know it. I've used debug command g=f000:a3be

Re: 8086 emulation

Now that the emulation problem is solved I want to explain how to determine the version of the game that you are using, because the game itself won' t test CPU type and loading the 286 version on a 8086/8088 will hang the system without any explanation: There are (at least) 3 types of Titus executa...

Re: Sharp PC-4521 in PCem?

I do think many manufacturers used NEC Vxx series mainly because them offered better performance at similar or even lower costs than the Intel 8088/8086/80186 I don't expect to see anything using 8080 (8 bit) code on a XT clone, 8088/8086/80286 emulation should do the job for most BIOS and all PC/XT...

All floppy formats for all machines?

I'm pretty sure most users would appreciate an option to select floppy disc controller on all machines as we can do now with the hard disc. At least there's one driver called "2M-XBIOS" to make this posible without the need of BIOS support when the controller supports the higher data rate ...
