About

I am a vintage computer enthusiast and collector, with a main focus on Macintosh and UNIX systems. In addition to computers, I am also interested in the history of the semiconductor and microprocessor industry and produce digital photographs and art with various methods of chip decaping and with my microscopy equipment. With over 30 years into electronic hardware as a hobbyist, I am thrilled to design products to keep our beloved fossils from the IT era as snappy as they could have ever been.

A simple an elegant solution!

For MacBatt CR2032 PRAM Apple Macintosh battery

Exactly what I was looking for: A battery replacement for my Mac SE/30 where I don't have to replace the existing plastic battery holder, and one that utilizes much safer and common CR2032 battery. Simple installation, easy access, and works.

Super Cool RAM for Macintosh

For PurpleRAM 64MB (16MB x 4) 30-pin DRAM SIMM kit

Ohhhhh yeahhhhh… One step closer! Got my ROM & my RAM. I’ve been dreaming about using these Purple sticks or RAM and ROM on my dream computer, SE/30!
I’ve bought other stuff from him and it’s all quality at a good price.
I also recommend getting the shims he sells for the ROM and RAM. RAM totals the 128MB limit and a 2MB ROM. I do recommend 2 shims on the ROM if you have issues with your plastic slot. Just so excited for this.

Fast shipping!

Board is beautiful! Haven't used yet, but it's simple enough that looks and simple ohm test show it's a great product.

Great product at great price

For SCSIknife desktop - ZuluSCSI™ compatible emulator

Being concerned about the longevity of the ~25 year old SCSI drive in my HP 16700A logic analyzer, I started to look for future proofing options. Other people have replaced the hard drive by SCSI2SD adaptors, but those tend to be fairly expensive(~120 USD not including shipping). Cheaper models exist, but still end up being >80 USD with shipping. This is further complicated by EU import fees. Then I found the SCSIknife, which is basically the same thing, but at only 49 USD *INCLUDING* shipping.

Placing the order during the weekend, the seller informed me on the very next work day that the unit was shipped. The delivery was in transit for 14 days, which was within the timeframe mentioned by the seller. The SCSIknife PCB itself was in an antistatic bag protected by a bubble-wrap padded envelope. Included was a short folder/sheet with specs and getting-started instructions.

Having no experience with SCSI-based disks, I had to spend some time getting familiar with the concept of termination and move some jumpers around, but following that, it was simply a matter of connecting the hard drive to the SCSIknife and cloning to the SD card started automatically. I couldn't get SD card reader mode to work, but was then informed by the seller that I needed to add an ini file with a specific string. This piece of information is "hidden" in the ZuluSCSI documentation, but the seller helped me out here.

The product itself works great. It has significantly sped up boot and read/write times of my aging logic analyzer and I'm no longer concerned about data loss in case of disk failure, as I can now easily back up the system hard disk.

All in all a great product at a very favorable price. Thanks a lot!
