RamKeeper on IIGS Rom 3

October 14, 2016

I’ve been wanting to use my RamKeeper as a ROM Boot disk on the IIGS Rom 3 computer since I don’t have a spare SCSI drive or MicroDrive Turbo. This is the same IIGS with the new DVI adapter. 

I installed the Ramkeeper in the IIGS Rom 3 but the IIGS wouldn’t boot. I would get a RK 102 error which meant incompatible memory configuration. 

After many efforts with different memory configurations including with and without the SlotMover I checked the Internet. 

I found an old forum thread that talked about Rom 3 IIGS not working with earlier versions of the Ramkeeper. 

So, I installed the other Ramkeeper I had which had a rev 1.6 Rom chip. My other one was rev 1.3. The rev 1.6 version worked nicely. They only issue with this card was the wires connecting it to its transformer were loose so it would not keep configuration after I turned off the IIGS. 

So, I pulled the rev 1.6 chip from that one and installed it in the RamKeeper with the original ribbon cable to the transformer. It works nicely. 
I see the Ramkeeper with a 1.2 meg Rom Drive to hold GSOS and CDAs and NDAs. 

I also gave it a Meg of Ram Drive for loading programs or Mean18 golf courses. 

The latter do run much faster from the Ram Drive. 

I have the 1.25 meg of Ram on the IIGS motherboard and a 6 meg GS-Ram Plus.
After copying various NDAs and CDAs to the Rom GSOS I copied that set to a 3.5″ drive.

I labeled it LoadRom.
Now, the RamKeeper can only handle 4 disk drives in the chain including Rom and Ram drives.

So, I have the following:

Rom Drive

Ram Drive

3.5″ Drive

And the Floppy Emu with number of Hard Drive images reduced to one. 

I started with GSOS on the floppy emu.

RamKeeper, SlotMover, GS-RAM PLUS

October 13, 2016

Upgraded my IIGS Rom 01 with RamKeeper Card with the SlotMover and a GS-RAM Plus 6 meg memory card. Here are some pictures and the brochures.  See the Commodore power supply that works for the RamKeeper. I found it recommended in a couple forums. They’re readily available on eBay.



The RamKeeper required it’s own power supply to maintain what was in the ram drive. The above is a Commodore power supply the works.


TransWarpGS on my IIGS Rom 01        TransWarp MicroDrive Turbo

I bought this IIGS on eBay. I noticed some interesting connections on the picture of the back of it. There was no description of what was inside. It had the TransWarpGS and a RamKeeper card.  Best find I ever had. The hardrives depicted on the screen are actually partitions on my MicroDrive Turbo from ReactiveMicro. It’s a CF Card on a circuit card which can be placed in almost any slot. Very fast even without the TransWarpGS.
