> I'm looking for an 1802 version of Tiny Basic [as originally distributed]. There's one published in the RCA "Instruction Manual for the RCA COSMAC Evaluation Kit CDP18S020 [#MPM-203] and the EK/Assembler-Editor Design Kit CDP18S024", #MPM-224. It includes the object listing (hex bytes and memory addresses), and Tom Pittman's user manual. RCA sold this version on paper tape. Tom Pittman sold a slightly different version himself, on paper tape, which included the "Experimenter's Manual". This may be the one you are thinking of. I have both, and am only aware of two differences between them: 1. The RND function in RCA's version has 2 arguments; RND(exp1,exp2). Tom's version has 1 argument; RND(exp1). 2. The RCA version has 3 addresses already patched to point to the UT4 monitor's console input, console output, and tape reader. Tom's version required that you add these patches yourself. The TMSI Tiny BASIC I posted on the cosmacelf website is derived from the RCA version. - Lee Hart, published in cosmacelf Yahoo Group post, Sept 2016
