A600 8Mb fast expansion

[rkauer]

 Just another question.

 Do I need to relocate the hd of the A600 with this new design, like the old one?

I've seen the 2.5" IDE support only on some not-very-good photos. But it is situated just over the CPU, no place for anything over it. So I think yes, you have to relocate. I can recommend you using CF-IDE adapter which works just fine, cool and noiseless, and could be stored anywhere inside or outside A600

OK, then.

 But my wife will complain about it:

"You buy another gear to your Amigas?!?! SD card, adaptors? And the hd you bought last month?" Aaaargh! :whack::destroy:

I am more confused than ever about how this fits in the A600.

Any pictures of you putting it in place?

2-level board connected with standoffs?

@ rkauer, Know he feeling...

I'd love to see some sort of video tutorial or detailed pictures of it being installed.

In the A500 and A600 uses a MC68K, on ACD32 uses an MC68EC020, the connections points aren't the same.

I know that, I'm just saying that a fast RAM expansion for the CD32 would be very welcome.  :-)

New (2008 year) board is ready!

Features:

 - PCMCIA-friendly

 - Better CPU and chipset ICs cooling than in old (2007) board

 - highly configurable by only two jumpers:
   * no fast memory
   * 8 Mb autoconfiguring fastram, no PCMCIA
   * 4 Mb autoconfiguring fastram, PCMCIA available
   * 1.5 Mb "slow" ram (but actually no wait states) at $C00000-$D7FFFF (automatically detected by kickstart)
   * 1.5 Mb "slow" + 4 Mb autoconfiguring fastram, in total 5.5 Mb with PCMCIA

 - Could be used with A500 as well (requires soldering skills), and with virtually any 68000-based device (requires CPLD firmware modification).


Some photos:









Orders could be placed at http://amigasc.nm.ru

 Superb work!:bow:

 Any chance to use a selector switch behind the A600 to avoid keep opening it?

 BTW: how is the price now, with the new design?

PCMCIA friendly. FANTASTIC!!! :-D

I dont quite understand the options. All this talk of Fast RAM, Slow RAM, PCMCIA friendly, not PCMICA friendly? Whats the max RAM i can have without disableing the PCMCIA port?

It's a jumper, just solder two wires to a dipole switch.

7.5Mbytes in PCMCIA friendly mode should be good enough for most A600 applications (i.e. WHDload). I doubt I'll ever change the jumpers.

@LordV
Do you think there would be enough height clearance to use one of these??

 If you use a bit longer pins, why not?

 Or just put some insulation between the boards.

@rkauer:
if you'd like to switch between all modes without opening case, you have to solder three wires. There are 4 pins in square, two pins are ground, another two are connected to CPLD. POssible configurations are: no jumpers, one of two CPLD wires shorted to ground, both shorted to ground and CPLD wires shorted together but not to ground - five modes in total.

I'll write soon manual for this board with everything explained

Heh, I've used exactly the same thingy, it was located outside A600 with ribbon cable going from it. And then, eventually, it died. Since that I use this: http://www.espada-tech.ru/pr_-25410.shtml Of course, outside case (and without that metal bar).

The benefit of the one I mention is that it is internal, no data cable, no power cables. Just plugs directly ontop of the IDE header.

I'm not sure there will be enough clearance but we'll find out.

 @Alexh.

 Like I'd say before, put a piece of mylar between the boards and you are done. Even with enough clearance, it is a safe measure (remind the 8Mb board is standing only in the CPU PLCC connector).

I was probably the one of the first to place an order yesterday evening minutes after Lordv posted and at 2pm today I get this mail:

I know I filled in the form correctly. D'oh I hope I've not missed out :-(

[lordv]

Of course some insulation could be done. But with SMD PLCC socket the boards sits rather tight. You can fit some plastic stands in the holes on the upper part of board.

Regarding amigasc.nm.ru, there are still some problems, so if any, please contact acidrain directly at staspi yandex ru (insert @ and . appropriately).

I'm going to order some approx. 20 PCBs and parts and start soldering it.
