Re: Looking for a BASIC trick for RESTORE N

So what's this doing? POKEing the address of the line into BASIC's variable that remembers where to continue reading?
*edit*
Never mind, figured it out. Didn't notice it was a subroutine right before the data.

Re: BASIC compiler?

The BASIC program is smaller because it's tokenized and most of the code is in the interpreter. The compiler has to generate assembly to replace a lot of what the interpreter does, so the code has to be larger. As for SIN, the compiler probably uses BASIC's floating point library, so that part isn't...

Re: Oric Kong converted in C, need beta test (and graphist !)

Even if I don't intend to include this music on my project, I think it is interesting. May be you can fork my GitHub, ans try tout see how you can include your music. Why not. For now, I spend a week in Paris and back home tomorrow. I will be able to have a closer look to your music at that time. I...

Re: Oric Kong converted in C, need beta test (and graphist !)

Someone was "hacking" the Atarisoft version of Donkey Kong for the Apple II, so I ported the music player I wrote for the Oric to the Mockingboard, and created the background music for 3 of the tunes from the arcade game. Here's the link to the player, and music data. The data will work with the Ori...

Re: House fire

I just checked UPS with an Austrian city picked at random and it was over $100 to ship! :shock:
I think mail is cheapest.

Re: House fire

BTW, if you check out one of the recent VZ emulators, if the VZ starts up and says "BASIC+", that's my hack job of re-enabling the Level II BASIC commands. :)

Re: House fire

The VZ200 is fun - I remember hacking on them in the shops at Dick Smith Electronics during one of my weekly "scouts for magazines that mention the Oric" and thinking 'phew, good thing I did not get one of these!' .. ;) Seriously though, if you want to send the Oric-1 on to a fan, I'll take it off ...

Re: House fire

Well, the only computer I have that rivals the Oric in size is my VZ200 (which I haven't found yet) so you have a point there.
I'm largely moving to emulation through software or an FPGA board though.

Re: House fire

Just a tiny bit of good news in this disaster. I've had time to sort through some of the things I was able to salvage from the house and had time to dig around in my storage unit. It seems I moved my boxed NEC TREK and Oric 1 to storage shortly before the fire. So... my Oric 1 is in pristine conditi...

Re: C64 Pascal source code available

I take back my earlier comment. I can't find the portable source for the 6502 portion of the UCSD interpreter (yet) and the disassembly of Apple Pascal is in a less than usable state so it would probably be easier to port G-Pascal. I also looked at the G-Pascal source a little longer and I think it ...

Re: C64 Pascal source code available

BTW, if I remember right, Java Bytecodes use a mix of 4 temporary variables and stack so I guess you could say it uses 4 registers of sorts.

Re: C64 Pascal source code available

Sorry to dig up an old topic but I just took a look at the assembly code for the compiler. For the most part the compiler portion should be easy enough to port. It appears to have two parts, a tokenizer and the compiler. It uses the usual character in/out, line in/out type I/O which is easy enough t...

Re: Cumulus Preorder Thread

Nobody was hurt but not much survived. What didn't burn has water and smoke damage. I'm insured and it's just stuff. My Oric 1 is MIA and my Atmos has damage to finish of the black plastic and keyboard. I have no idea if the Atmos works. The weird part is that I have a spare Atmos keyboard which was...

House fire

You can remove me from the list. EDIT: Done (and sorry for the loss, hope you will recover from that)
Most of my 8 bit machines were burned in a house fire and I will have other priorities for the foreseeable future.
