I recently acquired a Fastlane Z3 and I must say how impressive this card is. Fast SCSI controller plus you can put up to 64MB of ram on it. I had to upgrade my buster to 11 since I have an Amiga 3000 which got things working on the RAM side. There's a company making new buster 11's out of England I believe.
Equally fortunate to find a company (keystronllc) on ebay that specializes on making new 'old style' ram. I remember back in the day when 30 pin ram was so expensive. I could only dream of a full motherboard of zip ram and an expansion card with 30 pin stuff. Glad to know there are companies still making this stuff.
Also thanks to user here who is sending me a new v8.5 rom for my Fastlane. Hoping that fixes a few scsi bugs.
Now onto Picasso II card and hopefully an 060!
