Jumped in for one of those myself today.
I wonder what they are thinking..

Mine arrived today and it works perfectly on my A600 after using Prepcard

Are you getting a nice speed boost on the 600?

Haven't done much with it besides booting up Settlers and prepping the card in WB but didn't really seem any quicker.

Thats because PCMCIA ram still shares a path with the Custom Chips, so although you get upto 4mb of fast ram its not really going to give you much more in terms of speed.

Think of a PCMCIA Memory Upgrade as a Capacity boot, not a speed bost.

Now true fast ram, as in (CPU only) will boost a stock machine about 30%

PCMCIA memory is "SlowRAM"? I guess so. Does that mean that if you activate the full 8Mbytes on the A608 that half of it is SlowRAM?

Previously the only time I have heard mention PCMCIA RAM being slow is in the A1200 is PCMCIA SRAM slower than "FastRAM" cos it is 16-bit and not 32-bit.

Same here. Wow, that was fast shipping, although it was just up the Coast a bit.

Seems to work great on my 1200. (I know, it's slower 16bit, etc.. I haven't decided what I want to do long term to expand my Amiga, and figured this would be a decent stop gap)

What I've found so far is that, of the WHDLoad games that were on the HD when I got it (about 10 of them), the games for the Amiga 500 seem to work with the extra 2M fine.

The PAL/NTSC thing is still a bit annoying, but I can make that work too.

The games which won't run (complain about shadowmem or extram) are the AGA games.
Even when I give them as much memory as I can, and even when it's more than the READMEs say I need, I still get that error, so maybe those slaves don't like the 16bit RAM, or maybe I still need more for those. (Eventually)

However, for about $50 for something I'll probably able to sell when (if) I upgrade to real 32bit RAM later (or more likely keep as a backup) that gives me a bit of a buffer for now, I think it's a pretty good deal.

Cammy, thanx for the heads up!

Hey desiv, have you tried running those AGA games from AmigaDOS after booting without a Startup-Sequence? It's possible that Workbench is using too much ChipRAM for the games to run.

Allen1 · 28 January 2010, 23:51

A few AGA and CD32 games will work with a 2meg SRAM card although there are more that won't than those that will

Once you get a trapdoor expansion you will probably get the lot, I wouldn't get rid of the SRAM card though as they are also great for the A600 where a lot of "non AGA and CD32" games work fantastically well with the memory card

Not yet, will do, but I did set my screenmode to 2 colors which didn't take much chipram...

I'm still going to try the no-startup bit and see how I can do with Max free memory... Especially since the startup-sequence on this 1200 has a lot of stuff on it. It's a complicated collection of startup scripts I haven't gotten through yet, so I'm not sure what all it is doing.. :-)

I'd say it's all those extra bits running from the Startup-Sequence that take up those precious few kilobytes you need. Running WHDLoad games from CLI is simple too, you just go to the path of the game, for example:

Work:Games/Platform/Game/

Then type in the command to run it:

WHDLoad Game.slave

I was having problems not being able to run any games from Workbench on the 2MB A600, but some of those worked fine once I booted without a Startup-Sequence.

Good call.

Of the 6 AGA games, 3 worked that way.
I do have to go through my startup-sequence files and clean them out a bit.. :-)
