So it’s been a while since I did anything major. I did do another spin (My third so far) at the laser cut Microbee case, which revealed I needed to refactor parts of it.
I tried to make a fastening system so the upper half and the lower half could be screwed together, but I was too clever by half, and it was never going to work. Thinking about the problem, I came up with a new solution which is dramatically simpler. Back to Artifactory on Wednesday to cut more MDF.
I do look forward to finally being able to cut this from acrylic. I think it’ll look awesome.
So I was work from home for a week, and, of course, everything I’d ordered for the last few months finally arrived last week. The last two packages trickled in today.
This will mean I am much more able to continue with some projects. I’m a little limited on free spending money right now, but the components I need should be local and cheap.
By the way, none of the following was sponsored. All purchased with my own $$$. If any one feels like sending me stuff to review, reach out! 😀
This first item is an External Floppy drive adapter for the Amiga. I plan to use this to add a second drive to my Amiga 1200 when I finally laser cut the box for it. I plan to use the drive that was the internal drive as the second drive. Purchased from Sordan.ie via ebay.
Next up is a pair of PCBs from JLCPCB. The blue one is my own creation. If it works, It’ll plug into a ROM socket on a Microbee and offer 16 different ROM addresses. No idea if it works yet. The theory is pretty simple.
Next up are a pair of Floppy disk controllers. These are for the MSX PCB above. I ordered two in case one was a dud. Now I’m hoping both work. More on that in a bit.
These are 10 27C256 EPROMs. They’re 256 Kilobit roms. 8 KB each. Also purchased for the MSX project. I have no doubt I will find uses for the other 9.
Finally we have the star of the show. This is a Microbee DRAM Core board. These will clip into one of my existing Microbees, upgrading them from 32K to 128K, and also (once populated) add a floppy drive port. This particular core board is out of a Star Network Workstation, so is missing all the floppy drive logic. Guess what? The key chip is the WDC37C65C Floppy drive controller. Have we seen that anywhere? 😀
All in all, there’s only a handful of chips that need adding and a mess of passives. I need to catalog exactly what is missing but i’m hopeful I can either get it all locally.
Once I have it working I plan to add a Gotek to it. After that I think my stash of Goteks will be dry. Oh well. I’ll have to order some more. I got a good run out of the last order of 5.
