Hi IIGS users :)
I'm new to this forum, so I hope it's the right place for this message. While I had an Apple II many years ago, I never owned the amazing IIGS. Last year, I found one on eBay (a ROM03), and while it worked well, I found it to be reasonably sluggish while using GS/OS. Also, memory was a bit limited out of the box. So trying to overcome these limitations, I decided to fix both issues with a board I designed (the AppleSqueezer GS) that can be plugged straight into the CPU socket of the IIGS. It contains a 14MHz 65816 that is used to accelerate the IIGS. Additionally, it expands the memory so the total is now 5248K (nothing needs to be plugged into the memory expansion socket). The board uses several methods to accelerate the CPU, most importantly caching. The AppleSqueezer GS is basically somewhat comparable in functionality to a Transwarp GS, but made with modern components, the addition of memory expansion, and designed from scratch.
The board works very well on my ROM03 IIGS (perhaps I could post a video), but since I don't own a ROM01 GS, I was wondering if perhaps someone would like to have a peek at it and give it a bit of a test run on their machine. Ideally someone who wouldn't mind if we could exchange some messages to see how it performs, etc. Also, I'd like to receive the board back (although this is up to negotiation, I suppose ;)
I'm situated in the Netherlands, so a European user may be the easiest, but US would work as well.
By the way, I have no idea if others would be interested in purchasing an AppleSqueezer GS, but if so please let me know by responding to this message. If there's enough interest, I could consider producing some more. The components aren't super cheap (especially given the current chip shortage), but the price would be quite a bit lower than the $450 I think i saw advertised somewhere for a Transwarp GS.
Have a nice day, and thanks in advance for your interest and help!
