[Coco] 4K CoCo 1 & EDTASM+

[Simon Jonassen]

CLOADM works fine from colorbasic

Another thing you can try on the edtasm cart on a 4k machine is from the
editor, do a A/IM/AO

Assemble in mem at absolute origin

Then flip to zbug type Z at the prompt

At the zbug prompt type P FILENAME start address end address exec adress

EG: p test e00 f00 e00

I HAVE TRIED THIS ON XROAR WITH THE EDTASM CART $e00..$f00 doesn't trash
either edtasm or basic,and the resulting file loads perfectly on the coco

Wasn't "CLOADM" & "CSAVEM" not included in BASIC 1.0? I know there was
something about the cassette and ML that didn't come out until Color BASIC
1.1 or Extended Color BASIC 1.0 (the 1.0 quick reference card has CLOADM &
CSAVEM flagged as extended basic commands) When I got my Coco 1 from it's
original owner, there was a printer included. He said the printer worked
until he "got machine language" then it quit working (unrelated).
Since he didn't use computers much and had most of the terminology wrong, I
didn't understand until I actually got all the boxes he sent. In the package
was a tape for "Color BASIC 1.1" and a tape for "Extended Color BASIC 1.1".
The flyer with the tapes says something about the availability of Machine
Language programs. I'll have to go back through my stuff and find the docs
for the tapes.
The roms in the Coco 1 were "Color BASIC 1.0" and "Extended Color BASIC 1.0"
and from what I gather, he originally only had Color Basic and had it
upgraded by Tandy (service sticker in place of warrenty sticker).

Read about the /SR option but that applies to Disk EDTASM, the PAK assembles
only to tape so those should be simple one-chunk single origin binaries.
Maybe this its just stretching the capacity of the 4K RAM environment in
that CoCo 1, the routine is about 15 or 16 bytes long...
tried assembling yesterday again to tape using several origin addresses (no
errors reported on assembly), yet the final binary on tape comes up with the
?FM ERROR when attempting to CLOADM it in.
