Rockwell R65F11 FORTH
« on: December 22, 2018, 12:52:52 pm »
Had a surprise today. Ploughing through a pile of aquired 19" racks of bits and pieces and came across some Rockwell R65F11AP chips.

New to me, not Rockwell, thought at first it was their answer to the 6809, but turned out to be a 6502 with built in FORTH language.

Having read the data sheet nostalgia is certainly back, what a good idea. I find nothing of interest in the modern Raspberry Pie's and similar, doesn't work then add another 50MB memory solution.

Had a Jupiter Ace, long ago, never really liked it, the BBC B was so much better. The BASIC, and if you wanted assembler then you could create large assembler programs with a linking assembler, gave the disc drives a work out!

From queries, a photo of the board.

Called a Quaternary ADC, uses an AD7528, CA3300, HA5195 and TTL.

Rockwell was a second source for the 6502 soon after MOS Technology launched it. Ah, the good old days, when everyone want a true second source for most of their parts.  :)

Hi I have four "R1200-14, ROCKWELL 83, 9343 A32940-4, MEXICO". I have been unable to find any reference to them anywhere. They were bought in the mid 90s as R65F12, can anybody confirm that (or not)?

At least this page has the R1200-14 included in a list of Forth benchmark results, so that's promising.  :)

Terrible display; I had a look at it and could never get on with it despite being a FORTH fanboy at the time.  Never understood why they sell for silly prices.

Found 10 pieces of the same "R1200-14".
I have also trouble to find reference data of this stock.

Perhaps this could be the right datasheet!?

I took over the electronics workshop of my predecessor at a university and am currently digging through many treasures from past decades.
It may well be that more special treasures will turn up somewhere, such as the Tectronix 577-D1-177.
