Ethan ( et al );
Is the INS8073 the one that has a Tiny BASIC built-in or runs out of a ROM ?
It has an onboard ROM that takes up a known part of the 64K memory
map. The reference design is the CPU, a clock, level shifters
for serial in/out, an 8-bit SRAM (at least 1K), and some resistors
to set the baud rate. No external ROM required (but you can stick
a ROM on it with TinyBASIC code in it and it will autoexecute).
Is it a Tom Pittman type Tiny BASIC ? Thanks.
Yes. If you are used to working with Tom Pittman's TinyBASIC, the INS8073
will be a familiar environment (I can't guarantee they are identical, but
they are certainly peas-in-a-pod).
There were a few articles back in the day in Byte and Dr Dobbs, etc.,
about the chip and its BASIC. I think they are easy to google for.
Best regards, Steven
P.S. I've used the Rockwell chip that has FORTH built-in ....
I've heard of that, but haven't used it. Same goes with the RCA 1805
w/FORTH onboard. I know lots about the 1802, but not the ones with
FORTH.
