Title pretty much says it all. To qualify, the computer must have been manufactured and released. No prototypes or computers that never shipped.

Also, I'm looking for computers used at a home or small business. No mainframes or NASA guidance systems.

Thanks.

  • What about socketed PLCC devices (these are surface mount parts by themselves), or TQFP chips used as display drivers in early laptops? – rackandboneman May 2 '18 at 19:30
  • Another thing to research: Data General One ... board photos on the net are inconclusive as there have been multiple later versions of that machine. – rackandboneman May 2 '18 at 20:51
  • @rackandboneman if the socket is through-hole, it would not count. I hadn't thought about display drivers in portable computers. But I don't see why that wouldn't count. – cbmeeks May 3 '18 at 12:34
  • Display modules tend to be made by specialist vendors and sold as a component, with the driver chips already installed.... then and now... – rackandboneman May 3 '18 at 14:07

The TRS-80 Model 100 (and clones) and the Timex Sinclair 2068, all from 1983, all incorporated surface mount components.

    If anybody's sceptical of this, as I was, see e.g. techrepublic.com/pictures/tandy-trs-80-model-100-teardown/26 (a Model 100's LCD driver chip) or atkinsoft.com/images/IMG_0714.JPG (someone's in-progress switchable ROM modification of a Timex Sinclair). – Tommy Apr 22 '17 at 19:24
  • That's a very good entry! It looks like the TRS-80 Model 100, Timex Sinclair 2068 and the TI CC-40 computer all came out in 1983. According to Wikipedia, the TI CC-40 came out in March 1983. Do you know when the others did? Also, not sure if the CC-40 used SMT. – cbmeeks Apr 25 '17 at 15:20

A number of MSX machines started to use the so called "MSX engine" chip, which condensed a number of discrete ICs into one SMD chip, most often a TQFP one. The first MSX Engine was the Toshiba T7775 chip, which was used in the Sanyo MPC-1, as early as 1985.

One of the Macs has to be a strong contender; per a 1989 edition of InfoWorld "All the Macs are extremely well-built. There is extensive use of surface-mount technology ..." so at that point it's considered to be worthy of mention. Of the Macs under review there, 1989's SE/30 shows surface-mount components alongside through-hole and socketed, suggesting it is from early in the design transition.

  • Nice entry but I'm pretty sure there were many computers that used SMD before 1989. In fact, I just recently discovered that the 1541-II (floppy drive for C64) has a surface mount chip! Which I believe was in 1987. – cbmeeks Apr 25 '17 at 15:12
  • @cbmeeks yes, this has been thoroughly debunked as a potential answer, by at least six years on the 1980s computer industry hardware development scale. Which in human terms is about thirty centuries. – Tommy Apr 25 '17 at 15:51
  • The MacPlus used memory modules that were populated with surface-mount RAM. That would be 1986. – Whit3rd Apr 28 '17 at 10:45

The Epson HX20 from 1981 uses an LCD module which uses surface mount driver ICs.
