Big find - OKI processors
Posted by TheBelgianZombie@reddit | vintagecomputing | View on Reddit | 15 comments
Hi guys, got these in my possession and was wondering if anybody knows anything about them + if it is worth trying to sell/find a collector for something like this?
all I know is that some guy I know his dad used them to make his own dialysis machines in the 80s & 90s.

Imo you should sell those on ebay, or register yourself to the vcfed.org forums and offer those there in the marketplace worldwide or local.
I assume there should be the right people :-)

It would be helpful to have close-up pics showing the numbers on each type of chip.

So it's mainly OKI MSL9650-01AS 90 (x25) and MSL916AS 9688 (about 150) And then some : MOSTEK MK3880N Z80-CPU SIL 4013BE 863 7514 CD4023BF RCA 910 UA747CN MALAYSIA 7832HB CD4076BE RCA 927 MC14011 CP 7634 CD4076BE RCA 910

The CD4###xx and the 4013BE chips are all CMOS logic gates. While these are pretty outdated, I am pretty sure someone still makes them. They are only worth about 10 cents each.... They are useful for projects for someone that wants to work with CMOS chips, but I don't think most hobbyists are going to mess with CMOS gates.
The MC14011 is more CMOS logic, but I am not familiar with that series.... Looks simple enough, though.
UA747CN is an Op-Amp. It a core component for a lot of electronics projects. Worth about $1.

TI bought the CD4000 line from Harris years ago, and a lot of them are still in production. The MC14011 is the same as a CD4011.

The 1 in front of 4011 is what threw me. Admittedly, my limited knowledge of CMOS logic is quite dated.

MC1 is Motorola. You get used to it after a while.

I think they're parts for a printer
Definitely not something used in any computer I know of
Super super niche, cant even find a datasheet. Probably not worth anything

One appears to be a flourescent display tube driver

Neat find, but yep theyre kinda worthless to most people. Stick them on ebay and you may make someones day but its niche enough where theres likely to be zero interest
Im_100percent_human@reddit
Those could actually be useful for a project, though you could find another way to drive a fluorescent display, it just would take more work.

Somebody bought a few MSL-9650-01AS chips on eBay in February, so somebody needed/wanted them for something. Unfortunately, it’s old enough I couldn’t find the datasheet.

Might be worth the try then listing them on ebay... Let's see how fast the turnover rate is! 😅

These guys know all about them : https://www.youtube.com/watch?v=H3VkKxmYI-0

Nice thx!
