SIP IC's

I had a dream where IC chips came in SIP form, eg a shift register or a Microcontroller, maybe they have their uses requiring only 1 row of pins, they would be great for light shows not needing jumpers around/over/below traditional DIP's...

Maybe I'm the only one lol

You are the only one :wink:

There are SIP ICs - for instance, the Rohm BA6886 (and BA6886N) motor driver IC variants. I picked up a few of these from a surplus vendor (All Electronics, IIRC). I'm sure there are other SIP IC devices available...

One of my favorite LED drivers is a SIP: an6884 for sale | eBay

I remember the old SGI workstations used SIP chips for everything - it was they only way they could get enough chips on a PCB.

Wow, that is surprising...... I figured all sip style ic's were just resistor bridges.

I think the SIPs between the big square chips are RAM.

I'd agree, there used to be RAM SIPs a long time ago, whatever happened to them?

Some nice pics of 'big iron' there :wink:

I suspect my phone is as powerful as those SGI board were though...

BTW these days with surface mount and 6+ layer boards PCB signal routing isn't
a big issue (other than getting them off a large BGA!)

A complete "graphics card" was 4 of those big boards. Apart from that you had your CPU board, RAM board, hard disk controller (SCSI) and I/O board (RS232, etc).

They all slid into a huge box, like this one: http://www.sgistuff.net/hardware/systems/images/powerseries-1201-front.jpg

Probably 100x more powerful.

(and a lot quieter...!)

Somewhere I've an old Indigo workstation in the attic - a lot more sensibly sized.
MIPS r10000 IIRC

I had one of those, too. Nice shape, but no hardware texture mapping.

People used to make them into coffee machines. SGI even had an official version - the Expressigo:
