Okay, I was joking about the C64 game, "Impossible Mission" is referred to this idea.
Hi everybody!
So, I'm an happy owner of SCSI2SD v5 board, I use it in an external box, it works great and I use it on every SCSI Mac that I have, but they are too expensive in my opinion: I want to produce 2 boards for my childhood's lovely Macintosh IIsi and my PowerBook 145B, the 2.5 board "PowerBook edition" is more expensive than the 3.5 one so, why don't try to clone it? Obviously I clearly know that isn't an easy thing but giving a try isn't a bad thing...
On GitHub (https://github.com/vivier/SCSI2SD) I found SCSI2SD v4.2c (3.5") and v4.1 sources (2.5") with Gerber files and Cypress Creator's sources for the building the firmware.
I spent 2 days thinking about building the SCSI2SD's firmware and yesterday evening I built it with Cypress Creator, now I have 2 ELF and 2 HEX files and the question is: how to push the Bootloader and the Firmware HEX files to the CY8C5267AXI-LP051?
The Cypress LP5 PSOC that SCSI2SD uses supports JTAG/SWD protocols for programming, so, the best programmer for this PSOC would be the MiniProg 3, but it's too expensive (circa 88$), and here it is another question: what would be a "cheap" JTAG or SWD programmer for programming the LP5? Is this PSOC reprogrammable in case of bad HEX files? (I think yes, but I even want to ask)
Soldering SMDs component and the IC isn't a big problem for me, I did everything with my soldering station and I soldered a lot of SMD component in my life, the difficult thing for me is programming the PSOC.
Please, don't blame me, I repeat, I clearly know that is a very difficult thing, I also know that RaSCSI exists and it's the easiest thing to do (I also tried it with my Q700) but I want to give a try.
Thank you
