80186.

I was waiting for someone to say that !

Wasn't the 80286 in DIP too ? Bah - I've only got Volume II of Intel
Microprocessors 1991 manual ! I need Volume I to tell.


I might have spoken out of turn. The one time I did work with a '186,
it was in that square ceramic package with no leads at all - just
plated fingers on the top of the ceramic (around the lid) like an
edge connector. It went into the socket upside-down, as I remember.
But the socket still was on .1 centers, I believe. This was a very
long time ago, and I was kind of surprised to see the '186 come up
on intel's site today.
...
Turns out it comes in 64-pin PGA, 64-pin PLCC, and a couple of 100-pin
packages, whatever they are.

Hah !

I *did* have Volume I of the 1991 micrporocessors manual after all ! It was somewhat
slimmer than Vol II and I didn't spot it at first.

80286s were either PLCC or PGA ( 68 pin ).

80186s are presumably in the Microcontrollers Manual since I don't have any data on
them.

Looks like the OP would have to use a 8086 - or an NEC V20/30 - lol if he wants DIL.
And presuming they still exist ! Which strikes me as unlikely.

Not DIP, but I have done this. Soldered it by hand too. QFP208s can
be soldered by mere mortals (with patience).

Taking this 1 step further, what is the fastest ARM in a non-BGA
package?

The Atmel AT91RM9200 (180MHz, nice-to-have memory controller 16k SRAM,
no onboard Flash, 208PQFP) seems to be leader of the pack, but no LCD
controller.

Intel dropping the SA-1100 and Epson dropping the S1D13806 is proving
a real pain for me.

The masked ROMs I got from Poly Paks were 2513 character generator
chips for early computer terminals and were about 20 cents each. About
half were good.

I did one (well not 208, but 160) last week with the ordinary iron.
Someone had borrowed my Wavetip, so I just used the ordinary 2mm tip,
small blob of solder, PQFP pins and pads well fluxed, drew it INVERTED
(i.e. flat upwards) over the pins- very little solder wick required to
complete a working job. Much quicker than soldering a 64 pin DIP.

BTW, the CB radio chassis they sold was the "HYGAIN" 23 channel
design that suddenly was obsolete after the FCC added 17 new channels
and made the sale of new 23 ch radios illegal. A lot of hams bought
them and converted them to the 10 meter band with a couple crystals and
a re-tuning the board.

I think there may have been more than one, I have definitely seen 40ch models.
MC145106 was used so it may have been just a thing of replacing a switch.

All other good suggestions made here aside, how about a 68040 or even a
Pentium inserted into a wire-wrap socket? Or a standard socket, or no
socket, if you're thru-hole soldering your prototype.

How's your project coming along? Last August you got Linux running,
"Booted Linux2.4.26-vrs1 with USB root," but with "No CF, ethernet,
NAND flash, FPGA support yet." So how's it coming along since then?
