OSI 600D Superboard Build

Post by rubber_jonnie »

OK, so I'm starting to get serious about the OSI 600D Superboard build now:

I have started build boxes for the parts. Doesn't look much I know, but the keyswitches arrived yesterday, and I've started to get the sockets together. I also have a high quality pic of a built and working board that will help a lot with assembly, especially since I already know that the silk screen is 180 degrees out for a lot, if not all, of the IC's.

BoM is now printed out, so I need to start going through my stocks of parts to see what I have in stock and what I need to buy.

My main problem at the moment is the keycaps. I have a source in the US who has some, but responses to questions are a bit slow, but it may be down to Christmas, so I'll try again in January.

Luckily I am also in contact with the guy I bought the board off, and he's been super helpful, so should be a fun build :)

I foresee lots of soldering in your future. :-)
Intro retro computers since before they were retro...
ZX81->Spectrum->Memotech MTX->Sinclair QL->520STM->BBC Micro->TT030->PCs & Sun Workstations.
Added code to the MiNT kernel (still there the last time I checked) + put together MiNTOS.
Collection now with added Macs, Amigas, Suns and Acorns.

Well, minor progress, I have all the missing sockets on order, and tomorrow I hope to raid my spares drawer for some of the parts I know I need to get.

Annoyingly there are some logic ICs that I'll need 2 of, and I know I only have 1, but I can figure out what's left once I know what I actually have.

One big thing though, is the order of the keycaps. That is now in, though it wasn't cheap, but I think it'll be worth it in the end.

Seems I'm a numpty and forgot to specify wide 24 pin sockets and ended up with narrow ones :( Correct sockets are on order now, but I think I'm going to start assembly of what I have and then work out what's left to get.

I have a bunch of diodes and caps etc on the way so I can start to slowly get things built and don't have to do too much all in one sitting.

Well, parts are trickling in and I've just ordered the RAM and ROMs, Hopefully I can start building some time this weekend.

More good news - the keycaps are on their way from the US.

:)

Better get soldering with what I have!

Only thing holding me up is getting the Christmas decorations down and put away, but I'm nearly done now.
