Re: BASIC
Would it be possible to add a software bank commutation ? Like writing at ROM 0x0 for bank 0, 0x1 for bank 1, 0x2 for bank 2 etc... ? So a software like Enhanced Basic could use many ROM bank and switch when needed. This thread has diverged from it's original purpose so I have started a ROM switchi...

Re: BASIC
So the A16 you are referring to is the spare bit of the RAM address? If so, doesn't that give problems when counting the RAM on boot time? RAM A15 on the Gigatron PCB is the spare bit of the RAM address, you can use that to expand your RAM to 64Kx8. I wasn't very clear, the ROM A16 that I mentioned...

Re: BASIC
Other vintage computers use writing to address 0x0, 0x1, 0x2, 0x3 to switch the bank ... For 32 and 64 kb, it's very simple: one or two D flip-flops that are set to 1 or 0 by writing to the address 0 or 1 (2 and 3 more for the 64 KB). As a writing is basically groundless in this area (ROM), Thomson...

Re: BASIC
Good ideas from both of you, I won't respond in detail to them as they are all related mostly to the interpreter; I'll share where my thoughts are on the interpreter down below. Another idea I had was to forget about the interpreter completely and write a compiler completely in native code; how woul...

BASIC
This is long and there is no TL;DR that would do it justice, so if you're not in the mood, best to just ignore it. This is an open discussion for the implementation of a BASIC programming environment, I have already produced a number of core elements that such an environment would need, (generic gra...

Re: How to generate symbol table?
OK, I poked around a bit more and realized I somehow missed the Makefile in the root. I guess I was too caught up looking at stuff in Contrib and Core only. oops. I think I'm good now. Under windows I struggled with this for a while as well, I was going to write a quick howto, but instead of doing ...
