Re: OSI 600D Superboard Build
Well, the rest of the RAM is at my local depot ready for delivery today, I can only hope that the 74LS93 arrives today too, otherwise no amount of RAM will have it booting!!

:crossed1:
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.

Re: OSI 600D Superboard Build
Dammit. 20 RAM ICs in the post, but no LS93...
Though the shift lock 'bodge' switch arrived and looks happy in it's new home:
The problem is that actual latching shift lock keys are pretty expensive and Klyball over at OSIWeb, who changed the switches on the PCB, added this a workaround. If I can get the correct switch, it'll be going in.

Re: OSI 600D Superboard Build
Are the resistors going under the SHIFT key ?

Re: OSI 600D Superboard Build
They are, but they are no taller than the switch body so don't interfere.

Quite odd design, but at least they don't interfere.rubber_jonnie wrote: 23 Jan 2024 12:00 They are, but they are no taller than the switch body so don't interfere.

Yeah, you'd think they'd be flush like the diodes, but for some reason they aren't.HigashiJun wrote: 23 Jan 2024 12:06Quite odd design, but at least they don't interfere.rubber_jonnie wrote: 23 Jan 2024 12:00 They are, but they are no taller than the switch body so don't interfere.
Here it is close up with the key up:
And down:
So there is plenty of space overall. Annoyingly I ordered some 1/2W resistors rather than 1/4 for that 4th one along, and I may replace it later, but it's well away from the keycap, but I expect it's tall enough to interfere if it was in one of the spots.

Re: OSI 600D Superboard Build
what about using some SMD resistors?
If it ain't broke, test it to Destruction.
