This resulted in the Datapoint and 8080 instruction sets being so close that it was a snap for me to translate an assembly listing of the Datapoint "man and dog" program to CP/M, even though the ASCII graphics were being drawn byte by byte. That program was too cute not to port. For those who haven't seen it, MANDOG first drew a street with a signpost. Then a cleverly-animated figure of a man walked by (properly passing behind the signpost, of course). A few seconds later a dog came along, stopped at the signpost, lifted its leg on it (amazing what a single slash can mean), then continued on its way. -- cgibbs@sky.bus.com (Charlie Gibbs) Remove the first period after the "at" sign to reply. ###### From: bruce+usenet2@NOSPAMfanboy.net (Bruce Tomlin) Newsgroups: alt.folklore.computers Subject: Re: 1975 Microcomputers Message-ID: References: <3922B9BE.3879@azstarnet.com> Organization: San Antonio, TX Lines: 8 NNTP-Posting-Date: Wed, 17 May 2000 20:29:08 CDT X-Trace: sv2-A1zZro/Tu9Hy4NXVVoSQ+YEQK9bltk4geOqlvuZuJ/AHxhOpwnoH2cHH9dkqlQ4X7pZhh4rB1hRMBck!1aot7p4hFs0jrQxfXw== X-Complaints-To: abuse@GigaNews.Com X-Abuse-Info: Please be sure to forward a copy of ALL headers X-Abuse-Info: Otherwise we will be unable to process your complaint properly Date: Wed, 17 May 2000 20:29:46 -0500 Path: chonsp.franklin.ch!pfaff.ethz.ch!news-zh.switch.ch!news-ge.switch.ch!news.maxwell.syr.edu!korova.insync.net!solomon.io.com!nntp.giganews.com!nntp3.giganews.com!news4.giganews.com.POSTED!atuin.bruce!user Xref: chonsp.franklin.ch alt.folklore.computers:56598 In article <3922B9BE.3879@azstarnet.com>, bill_h@azstarnet.com wrote: > In a previous chapter he described the effort of Datapoint, of Austin, > TX Datapoint is (and AFAIK always has been) in San Antonio.

Dunno if there's any connection between that and the terminal controller you mention, but it's the same kind of application. Any ex-DSD folks please feel free to correct or expand on that... The mini that ran that system was the 990,which had the same architecture and instruction set of the TMS9900 microprocessor. In another thread, someone mentioned that the 9900 was odd in that it's general register set was held in memory instead of on the chip. That architecture did slow down execution of straight-line code, but it was outstanding at performing rapid context switches that were necessary for a character-oriented communication controller. A single BLWP (affectionaly called a "bullwhip") instruction saved/loaded three registers - a workspace pointer to the 16-register chunk of memory, a status register, and the 16-bit PC. The architecture encouraged modular programming. Any chunk of code that was fairly well localized with distinct in's and out's got allocated a workspace, and you weren't pushing and popping or doing local register save/restores all the time. People claiming orthogonality for the 8080/8086/Z80 never programmed a 9900. After writing many, many 10's of thousands lines of 9900 assembly code, I never could develop a mindset to memorize all the ISA strictures that had to be followed to program those things. Thank goodness Lattice quickly introduced a C compiler for the 8088 PC... I bought version 1.03, and never looked back at the 8086 assembly bletchery. -- --------------------------------------------------- best regards, Fred Wedemeier null@lycosmail.com ###### From: Eric Chomko Newsgroups: alt.folklore.computers Subject: Re: 1975 Microcomputers Date: 18 May 2000 14:03:46 GMT Organization: IDT Internet Services Lines: 14 Message-ID: <8g0t82$ln1@nnrp3.farm.idt.net> References: <3922B9BE.3879@azstarnet.com> NNTP-Posting-Host: u3.farm.idt.net X-Newsreader: TIN [UNIX 1.3 unoff BETA release 961025] Path: chonsp.franklin.ch!pfaff.ethz.ch!news-zh.switch.ch!news-ge.switch.ch!news.maxwell.syr.edu!feeder.via.net!news.idt.net!nntp.farm.idt.net!u3.farm.idt.net!not-for-mail Xref: chonsp.franklin.ch alt.folklore.computers:56566 Bruce Tomlin wrote: : In article <3922B9BE.3879@azstarnet.com>, bill_h@azstarnet.com wrote: : > In a previous chapter he described the effort of Datapoint, of Austin, : > TX : Datapoint is (and AFAIK always has been) in San Antonio. : (So was SWTPC, FWIW.)

I don't remember the speed factor but I used the Datapoint box and supported them as vendor field service engineer in the early 70's . Very interesting machine. I used a memory chip that required cycling through serially but still offered pretty good performance for the time.
