I need to buy a new memorycard for my GS, my old one isn't DMA compatible... I need to know what DMA compatible cards there are wich use 1 Mb Simms, I've got four megs left from uppgrading a Mac, so I want to use the with my GS Thanks in advance! /Rickard.

You can only stuff 1.5Megs on a GS-RAM, and 2Megs more with the 2Meg expander thing (which I've never seen around). Anyways, none of those use SIMMs, so those extra SIMMs he has will be wasted. >-- >Dj Padzensky >_______________________________________________________________________________ >Internet: djpadz@bonnie.ics.uci.edu | Neurotics build castles in the sky. >America Online: DjPadz | Psychotics live in them.

I have a Harris GS Sause, just got it yesterday. I have a ROM 3 IIgs and I
tried to use GS Ram by Applied Engineering, (yuck) this Harris works much
better. With the SIMMs there is none of this which chips do I get, which
way do I put them in? It very simple. I have 4 256k SIMMS in so with the
MEG already in my computer and the new memory, I now have 2 meg....

I have a GS Ram+ with 1 meg on board so far with my Rom 03 that makes 2 also. No problems. Whats your point? I didn't have any problems putting in my chips, and since its a "smart" memory card, you don't need to put jumpers on it. Any intellegent being *should* be able to figgure out how to plug chips in, and in the owners manual there is a list of a half dozen chips you can use. You call up marsh electronics, ask if they have them in stock, and buy them. NO SWEAT. Now the advantage to using the SIMMS is that you can steal all the memory out of the Mac on the table across from you, run some great memory intensive programs, and tempt the Mac user to keep up...

What's the price on > that thing too (bare, and stocked). Here's the answers to your questions: THe GSSauce will hold 4 Simms. If you're using 1 Meg simms, then that comes up to 4 Megs (I'll leave the 256K answer as an exercise to the reader :-). Yes, it's DMA compatible. Unfortunately, I think it'll only take 256K SIMMs and 1 Meg SIMMs. I kinda wish it'd take the 4 meggers. Price? Well, I think they're about $75 or $80 for an empty card. You can buy 8 bit x 1 Meg 80ns SIMMs for about $38 from Chip Merchant. It runs nice and cool, too. Cute little board... I love it. > ---------------------------------------- > Michael J.

So if you're using 1 Meg SIMMs, you'll have 4 Megs DMA, but if you're using 256K SIMMs (why would you?), you'd only have 1 Meg DMA... > Make sure that the dealer you buy it from has them in stock.

I purchased mine through Team Electronics of Mankato. It came with 4 256k
SIMMs and cost $100. It has a LIFETIME warrenty on BOTH the SIMMS and the
card. I don't know what DMA is, but it supports 256k and 1 Meg SIMMS,
totalling 4 meg. I have seen the 1 meg SIMMS here for $60. It's
compatible with the IIGS ONLY, but it works with System 5.04 (I haven't had
any crashes since I purchased it) and should work with older systems, but I
have tried them....

I have an 8MB OctoRAM and Apple's High-Speed SCSI card, as well as TWGS and FPE, all of which are fussy about DMA. The true story is that only the first 4 (of 8 total) SIMMs on the OctoRAM properly support DMA (due to an inherent IIGS design problem, not the OctoRAM's fault). The High- Speed SCSI Card detects when there is an attempt to transfer data to/from addresses above 4MB, and uses programmed I/O instead of DMA for those cases. This does NOT help when you use 8 256KB SIMMs in your OctoRAM, but it does when you use 8 1MB SIMMs. Another thing to worry about is that the Applied Engineering TransWarp/GS requires the latest PAL chips (TWGS-2B I think is the critical one) to work right with DMA devices, and both that PAL AND a TWGS hardware mod (lifting pin 1 of U22 as I recall) to work with Innovative Systems' FPE floating-point accelerator card. I will say that when one finally gets all this equipment working together it makes for a very nice set-up. (I also recommend configuring the upper 4MB as a RAM disk, to avoid ANY opportunity for DMA problems.) >Make sure that the dealer you buy it from has them in stock. Especially since the company that originally manufactured them (MDIdeas) has gone out of business. The OctoRAM's designer has been looking for another manufacturer.

That's correct. This is one of those little things that Apple does to 'help' third party vendors. I don't like it either, but then I don't expect to go above 2.25 meg anytime soon with my GS Sauce and RAMFast, so it's not a big concern of mine... Todd Whitesel toddpw @ tybalt.caltech.edu

No, but it does mean that Apple's High-Speed SCSI Card will not use DMA when transferring data between the SCSI bus and the upper 2MB of your RAM. (That is a rather unlikely case anyway.) The only effect should be somewhat slower SCSI I/O on rare occasions.

Actually this feature of the High-Speed SCSI Card was a deliberate AID to owners of memory cards such as the OctoRAM, not as you imply something that gets in the way. In fact, any IIGS RAM configuration in excess of 4MB violates Apple specifications. It was thoughtful of MattG to help out those of us who nonetheless have configured our systems with 8MB of RAM.
