Re: Experimental very fast tape loading

My proposal is modest but I think it makes sense - in short you don't need PHP/RTI in the interrupt routine. Use only RTS instead - gain 3 cycles and 1 precious byte. :) I.e. from: 04CD 4 AE 00 03 LDX $0300 Re-initialize CB1 flag 04D0 4 AE 08 03 LDX $0308 Read duration in X 04D3 4 8E 09 03 STX $0309...

Re: FastBoot/FastLoad on Pravetz 8D/Disk II

About the 'linear' loading here is what happens: when picture loop starts fastloader reads sectors: 09,0a,0b,0c,...,07,08... and so on until re-seek to track 1, on the second loop sectors are read: 0a,0b,0c,0d,....,07,08,09... then seek again to track 1, and yes, you guess it :) : 0b,0c,...,08,09,0a...

Re: FastBoot/FastLoad on Pravetz 8D/Disk II

Scalex, you are really good how you found this nice little trick! Respect! I've got the idea for RTS at $B800 like an "illumination" ;) trying to optimize the code size for FloppyBuilder, where one single sector have to contain boot code for Jasmin and for 8D. I'm sorry that I simply forgot to uploa...

Re: Experimental very fast tape loading

Congrats for victory, Symoon!
Your source looks super, I tried to tested it with some quickly written encoding code based on explanations in your file but failed. Anyway, my tests are not relevant and only for fun, I'll wait until you release the encoding part.

Re: FastBoot/FastLoad on Pravetz 8D/Disk II

Very, very nice! ... and this is your first demo (same pictures in the same order, endless loop) without optimizations. It's fast, but your time is better! :) It would be really very interesting (and useful) for me if you release sources. fbtest-1.dsk.zip And here is a modified Pravetz ROM, which bo...

Re: FloppyBuilder evolution

Well, attached is the updated version of the demo. Now it's QuadroBootable - Microdisk, Jasmin, 8D and Telestrat! TeleBoot-1.0.jpg In the archive (together with described images in my previous post ) you will find 'TeleBoot.rom' . Use this ROM file as TeleBank7 in Oricutron.cfg or Euphoric.ini (leav...

Re: FloppyBuilder evolution

I didn't know that B7 contains your updated version of disk i/o code (maybe I missed your post). I'll try to get synchronized with it asap (which means lot of work...). About Telestrat I think I understand what the problem is - it requires first sector to be 512 bytes, right? If so, this is related ...

Re: FastBoot/FastLoad on Pravetz 8D/Disk II

Don't worry about your English - mine is bad enough too :). I'm very interested in fastboot/fastload sources, where can I find them? I've already added support of Pravetz's DISK][ interface to FloppyBuilder, but it works very slow. My work is based on standard DOS-8D RWTS routine (which is actually ...

Re: OSDK Linux/macOS recent version?

No, they are not, and IMHO this is not good idea. Let's keep OSDK "as is". As I said it's easy to build OSKD for Linux - there are already Makefiles. Checkout http://miniserve.defence-force.org/svn/public/ , go to pc/tools/osdk/main/ directory and try 'make'. May be some tweaking and 3-rd party libr...
