Re: And you thought Falcon's were expensive

I think you really should have some sympathy with these poor souls that have to quarrel with their wifes' 'this dirty old thing must go' arguments with such last resort 'o.k. honey, I'll try to sell it' response :lol:

Re: 68040 machine

Apple did not reveal many details of the inner workings of their machines and required coders to set up on top of the OS only. If I remember right, there is Linux m68k available for the Quadras. I'm pretty sure you will find most of what you need in there, Linux folks have done a lot of reengineering.

Re: Credit card vs Debit cards on new webstore poll

Fully agree. I didn't even bother to read this thread until just now because I thought I wouldn't care anyway - owning credit cards and assuming everybody wants to buy foreign would have one as well. Regarding 2% general uplift: I would not care. Once Brexit really means Brexit eventually, nobody wi...

Re: Suska board

I haven't done a thing with mine yet. I can't simply plug in a ST floppy drive or hard drive to get programs onto it. Hmmm. The board has more interfaces an original STE has: ACSI, floppy and even a 'Putnik-compatible' IDE interface. It just does not have the original connectors (so you have to pro...

Re: Trudie - The Next IDE Board

Assuming PCs can't use more than 1 partition on a CF card (maybe someone knows ?) A limitation that (Windows-) PC's only have until Win 7 for hot-swappable media. On earlier versions, there are alternatives/extensions available. Windows 10 removes this limitation as well. So probably nothing you sh...

Re: BLITTER RE-CREATION THOUGHTS

... we are not stupid! Apologise if I appeared wanting to imply that and assure you: I didn't! The problem (and advantage) of FPGAs is that you do not have access to raw silicon as the original blitter designers had. On raw silicon, there are possibilities you do not have on FPGAs (or you are at le...

Re: BLITTER RE-CREATION THOUGHTS

Icky is working on just that. We are trying to clock the core at 32Mhz and clock the state machine (8MHz access) to still be a 8MHz clock. I would just clock the complete blitter (including the bus logic state machine) with 32 MHz. Then make sure signals going to the 8MHz side are kept stable for 4...

Re: BLITTER RE-CREATION THOUGHTS

Maybe it helps when we examine what the blitter really does: Blitter.png For each blit cycle and depending on the intended operation, worst case it needs to read the source word, read the destination word, do the logic op and write the destination word. It can't do memory accesses any faster than th...

Re: BLITTER RE-CREATION THOUGHTS

But the bus access is still being synced to 8MHz... you can't run the suska core at 32MHz as is screws up the 8MHz bus access... So it would need 2 clocks to work just to clarify, the BLiTTER is clocked with 8Mhz but the bus is 4MHz, but only every other cycle is granted.It means that we have 4 cyc...
