Wicher 500 - new turbo card for A500

spidi · 18 November 2016, 18:21

[ Show youtube player ] you can see the presentation of the prototype Wicher 500 turbo card for the Amiga 500.

CPU: 68000/68010 - 12,14,16,18,21,24,28 MHz,
FAST Memory: 1/2/4/8 MB EDO SIMM,
IDE Controller (Kickstart 2.05+),
SPI Controller,
RTC on SPI bus

Interesting, so it uses the expansion port rather than sitting ontop the old 68000 socket..
I have one of them old Blizzard Turbo mem cards that fit internally.. Gives me 14 or is it 16MHz 68000 + 2MB FastRAM. But no IDE.

Ballpark figure: How long before its done?

Why aim so low in speed?

+ for polish name

NMI and Action Replay III possibility would be fantastic

(in cooperation with the original author)
Did you try with scsi.device modded kickstart 1.3 ?

LuMan · 19 November 2016, 23:43

EDO RAM.... Good job I've still got some kicking around from an old DX2/66 I used to have..

But excellent work. A definite addition. Looking forward to more info.

Maybe it should be Wichura

- small cache (16 - 64KiB) could be nice...

Ratteler · 21 November 2016, 05:56

How much?

Now I am working on the implementation of the SPI Controller.
Performance turbo card at the moment

Waiting for a faster version called Błyskawica

Predseda · 21 November 2016, 15:05

Wouldn't you want 'Pogotowie Ratunkowe'?

Spidi,

your sync design gets every single cycle, that's excellent. From what I can see on the pictures, you should have the possibility to add a MapROM function, this will give you quite some extra speed on Sysinfo stones and IDE performance (unless you run a patched scsi.device that's already in fastmem - then you already have the best speed).

At this point, the ACA500plus (which is async, so loses a cycle here and there) beats your sync design just because of MapROM at 14MHz. You can beat the ACA500plus at 14MHz if you implement MapROM. However, you won't reach the ACA500plus speed if it's clocked at 21MHz or more :-)

Is the ACA 500 plus coming soon, just see the older version on the Individual Computer's site.

Schoenfeld · 21 November 2016, 16:59

Signman,

I didn't mean to hijack this thread, but to give Spidi some hints on how he can improve performance. I expect to have ACA500plus news early december. Please stay on topic here - it's Spidi's thread.

Jens

Very nice, but I dont have A500, I am more waiting for the A2000 version. Keep it up! ;o)

Amiga1992 · 21 November 2016, 18:32

Great job spidi!!

Thalion · 21 November 2016, 19:12

Nice design. I like the RAM socket.
