DOS/65

I connected with Rich last year (outside of the forum). He's been working on a 3.x release and sent me some early code. Now that I have my CF Card adapter working, I need to reach out to him and look at porting the latest version to my C02 Pocket SBC. The bulk of the code is 6502 only (no CMOS instructions used) but I think the hardware interface module might have had some CMOS code in there.

I saw C64 port of DOS/65, is it easy to port it to Apple II? I am not aware of such port and I am interested. There is USDOS, written by one Bulgarian programmer in 1990's (I think he was 12 years old when he wrote it) and it is 6502 only, if someone is interested, I uploaded it here: https://ftp.apple.asimov.net/images/mas ... /USDOS.dsk
Works with Applewin, Apple Oasis, AIPC and some other emulators, also works on the hardware.
It is quite impressive, the developer wrote Apple Oasis emulator later.

Suggest you take a look at the link below (and perhaps my Github page). I received some code from Richard earlier this year. Since then, I have it running on my C02 Pocket SBC with my RTC/CF-Card adapter. It's been running for several months now. I also reworked the CCM and PEM modules using CMOS instructions and addressing modes and was able to decrease the ROM space required.

As for getting it to run on the Apple II, no idea if it's been done. For the ROM version, Richard has gotten it working on the WDC W65C02SXB and Daryl's SBC2 with an SD Card interface that attaches via a 65C22 VIA port. I started with that code build and wrote my own Monitor code to interface to Richard's SIM module. I've since re-written SIM (now a newer version) that interfaces directly to my C02BIOS code. All of the DOS/65 modules I'm now using require a 65C02 to operate. I'm quite happy with the results so far.

Hope this helps...
