Someone contacted me recently, who has a 4/40 Intellec system they wish
to revive. They recall using Intel's "RAM resident macro-assembler". It
was apparently two paper-tapes to represent a two-pass macro assembler
written in 4040 assembly language. The 4/40 of course, did not have any
mass storage. They'd like to use that assembler again.
I'd forgotten such a product existed; I only knew of it through Intel
documentation, as the product is older than my Intel experience of the
era. I had to read my own Web page to confirm the product.
Anyone have any of that code? I don't recall any 4040 code in our
collective archives; they are a bit hard to review all at once.
Source for the 4/40 ROMs would also be nice. I've archived those ROM
binaries at least, or one version of them, thanks to Kyle Owen and his
4/40 system we confirmed a working set. Paul Robson provided a disassembly.

I reworked a once-popular 8085 cross assembler into assembling 4040 code.

I came across a reference to use of it, that assumed this was a product
of the original 8085 cross-assembler by programmer William Colley. Those
able to read a Web page and not just download ZIP files, can read my Web
page, and thus determine that I modified that Colley cross assembler to
support the 4040.
My general point being, work on 4004 and 4040 is very fragmented and a
bit hard to obtain these days.
