Re: New game for the BBC Master : Planet Nubium

I spent a bit of time this evening playing Planet Nubium. Really good game, different from, but obviously very reminiscent of Manic Miner. Great job! Thank you for your kind comment. Planet Nubium originated from my love of Spectrum games. I was experimenting with the BBC Micro to see if I could co...

Well, if it's a 6502 you don't need to port 6502 BBC BASIC to it, you just need the appropriate host interface veneer.

Re: Proposed: "The Ultimate Electron Upgrade"

Would BCPL, the forerunner of both the 'B' and 'C' programming languages, be a suitable substitute for these folks who are looking for a C-compiler for the Beeb?

Re: The 8-Bit Guy's new 65816 based computer

How realistic is it to build $50-$100 8/16-bit computers with multiple video modes and some I/O without FPGAs?

The Spectrum Harlequin does without either a ULA or FPGA, but replicating the functionality of the ULA takes ~40 logic chips!

From the video (at 12:30), the plan is to write a custom kernel. Cloanto will not licence the C64 kernel, either. His words are vague enough to be open to several interpretations, but it did sound to me like he's intending to write something similar to the C64 kernal. Given his extensive experience...

That said, I wish he wasn't using Commodore's Kernal and BASIC as a base. They're both quite primitive.

Hmm. That'll teach me to be lazy and read the datasheet rather than getting my scope out. I find it quite amusing Acorn would be shady enough use memory that isn't validated for a 250ns cycle time.
The Electron used 150ns DRAMs.

Re: Why was Repton so loved by BBC users yet so disliked by the Commies?

The memory speed needed to be double the CPU clock to provide cycles for the VIC-II, and 2MHz memory was cheap; the same choice was made by Acorn in the Electron. The CPU slows to 1MHz on RAM access so that cheap 2MHz memory can be used, rather than the expensive 4MHz parts in the BBC. The Electron...

The fabless business model won out. The disruptive GPU technologies since the late 80s/90s from Nvidea, ATI, Matrox, Hercules, 3DFX, S3 etc. all came from fabless companies. ARM has always been fabless. AMD went fabless when it demerged with GlobalFoundries in 2009. IBM sold its fabs to GlobalFoundr...
