ETA-3400 Tiny Basic ROM source?

[Chris Elmquist]

I've asked this over on the ET-3400 Yahoo group too but after Bob's recent
posting (and great story about his H9), thought I'd check here as well.

Does anyone have the source for the Pittman Tiny Basic ROM that was used
with the ETA-3400 add-on?

There is a ROM image available in the files section of the Yahoo group
and I've started disassembling it off and on but thought I'd check and
see if anyone had already done that or may have actual original source
from Heath (if that ever existed within Heath).

Any leads?

Hi,

Tom Pittman's Tiny Basic page:

http://www.ittybittycomputers.com/IttyBitty/TinyBasic/

has a link to a disassembled version of Tiny Basic for the KIM-1 (6502
processor). This may be a useful guide to the disassembly of the 6800
version you are working on.

Regards,

John Frankle

Thanks John. I have come across the 6502 version and it's a good point
that it can serve as a template. That'll be the Plan B if original
source doesn't appear (which I kinda think will be the outcome).

I know Tom, and he's a good guy. If you contact him, he may be able to
supply a copy of it. Tom wrote versions of his Tiny BASIC for the 1802,
6502, and 6800 (which is what the the ET-3400 uses, I think).

I have Tom's manuals for his Tiny BASIC and Tiny BASIC Experimenter's
Kit. The latter in particular has source code for the IL (Intermediate
Language Interpreter), and details on the I/O routines needed to run it
on various computers. If you'd like one, send me a stamped
self-addressed envelope with enough postage for 50 pages (my address is
below). NO, I won't copy it or scan it. If you want an online copy, get
it directly from him.

Thanks Lee.

I think the manuals you offer are available online and I've looked at
them in the past. I did see one email thread where Tom discussed how
his original 6800 source was lost and only the 6502 version remained.
And it is true that the ET-3400 uses a Motorola 6800.

Thanks for the offer. I'll review the online versions and if they are
poor scans I'll catch up with you.

Chris

That's good. I have original manuals (not copies), which is the only
reason I was willing to provide them. I don't want to copy the
copyrighted work of someone I know. Tom deserves the credit (or cash) :-)

Sorry to hear that. I know the 1802 version also survives, because I
retyped it in for him -- he has it on his website. I also retyped in his
"First Book of Tiny BASIC" and "A Short Course in Programming" books,
which I think he has on his website as well.
