MTXplus ICs

Post by lezanderson » 17 Oct 2016 10:43

Free MTXplus+ ICs

I'm in the process of getting enough ICs together to build 10 x MTXplus+ units.. all going well this shouldn't take to long and will keep the cost of building your own MTXplus+ computer down to a reasonable price. The ICs will be send to Dave's house. I'm sure Dave will post costing for PCBs + Edge Connectors etc. on the forum as well as build details when available.

What I could really, really, really do with, is a TARDIS.
  1. Would save me ending up in Cardiff when that's not where I want to be (see this thread) I hope (assuming I don't end up with The Doctor's dodgy one...)
  2. And I could use it so that I had more tinker time with MTX machines ;-)

Lez, can you get any dual port RAM chips like IDT7130LA35P or IDT7130LA55P (faster speeds okay, but not slower speeds) for a reasonable price?

Prefer 55ns or quicker. Does not have to be from the same manufacturer, just have the same functionality (dual port RAM).

I'm assuming you want these in DIP ??

I can get CY7C006xx,CY7C007xx & IDT7006xx,IDT7007xx,IDT7008xx in PLCC

CY7C006,IDT7006 (16kx8bit Dual Port SRAM) PLCC $5.0 each
CY7C007,IDT7007 (32x8bit Dual Port SRAM) PLCC $12.50 each
IDT7008 (64kx8bit Dual Port SRAM) PLCC $16.50 each
