Too much ingrained (and now codified by ANSI/ISO) that requires shorts to be at least 16 bits and longs to be at least 32 bits, neither of which the 8 supports well. Even the EAE or FP modules only added limited 24 bit support. -----Original Message----- From: TUHS [mailto:tuhs-bounces@minnie.tuhs.org] On Behalf Of Lars Brinkhoff Sent: Wednesday, November 29, 2017 1:56 AM To: Will Senn Cc: Tuhs Subject: Re: [TUHS] Unix on PDP8?

The tiny instruction set is surprisingly versatile!
