BWMS is a privatly owned 8 and operated system which is currently open for use by the general public. 9 No restrictions are placed on the use of the system. 10 It is intended that the system be normally used for messages and 11 advertisments by the users. As the system is privatly owned, I retain the 12 right to remove any and all messages from the system which are offensive 13 to me. Additionally because of the limited size of the system, it will be 14 periodically purged of older messages. (only 629 lines of data can be saved) 15 The saved information will be cycled to drive 'B' while the information on 16 drive 'B' will be archived, and a fresh disk will be installed in drive 'A'. 17 To leave a message, type 'ENTER' and use ctrl/C or break to get out 18 of the enter mode. The message is automaticly stored. 19 If after entering the message you find you made a mistake, 20 use the replace command to replace the line. 21 To exit from the system, type 'OFF' then hang up. 22 Type 'HELP' to see other commands that are available on the system. 23 ======================================== 24 Sorry about that, anyway here's a new disk for ya. 25 It seems that the usage of the system has gone up 26 radically of late, like befor I was having to change 27 disks about once every month or two. It is now less 28 then two weeks befor the drive overflows. 29 ++ I'm popular!!!! ++ 30 To those of you who have left comments in regard to me and 31 the system, THANK YOU. 32 It is nice to know you are apperciated (yes, I know it is 33 spelled wrong, but what else is new?). 34 In regard to my pervious comment on FLEX/OS9. I do not 35 change my feelings in regard to these operating systems. 36 It is not that they are bad per sa, but rather I find 37 that CP/M (which I use) to be far better for my needs. 38 Anouther point I might make is that I cut my hardware teeth 39 on the 6502 (Original engineering sample - no rotate right 40 and a bug on branching over page bounderies). I still like the 41 6502, and infact there are some things that the 6502 can do 42 faster then any other MOS processor (yes even the 8088!). 43 (Please compare proper technologies here. 44 Take a look at the clock timing charts. 45 8080-8085-Z80 JMP - 10 clocks 6502 JMP - 3 clocks 46 8080-8085-Z80 NOP - 4 clocks 6502 NOP - 2 clocks.) 47 Assuming a top speed Z80B, at 6Mhz (P.S. a 6Mhz 8085 has a 48 real internal clock rate of 3Mhz.) compared to a 3Mhz 6502B 49 we can run even or better on the most used instructions. 50 and with the 6502C at 4Mhz it's faster. 51 Accually, the real test of how good a proccesor is at speed 52 is how efficent it is at accessing its memory. If if processor 53 accesses its memory at the fastest possible rate, that is all 54 the speed it needs. (It is pointless to crunch the data faster 55 and then just sit there waiting for the memory to give you the 56 next instruction.) 57 Anyway, I use a Z80 now running CPM. This is because it is more 58 suitable to the things I am doing, and the information base 59 is far far larger for 8080/Z80 stuff of the sort I need. 60 So although I like the 6502, I use the Z80 because it gets 61 the job done. 62 *** YET EVEN MORE VERBAGE FROM CISTOP MIKEY **** 22 DEC 82 ****** 63 ADAM, 64 THANKS FOR COMMENTS, YES, THE LINKASM DOES SUPPORT SYMBOLS 65 BY TYPING THE DRIVE NAME AFTER EVERYTHING ELSE (LINKASM TEST.AAZ A:) 66 AS TO IF IT WILL WORK WITH SID, I DON'T KNOW AS I HAVE NOT TRIED 67 IT.

A simple register to register move takes 2 clock 141 cycles in the 8088, 4 clocks in the 8080/8085/Z80 and 2 clocks in 142 the 6502. 143 It would seem to me that this 8 year old micro can still hold its own 144 ground against the lastest and greatest and at a heck of a lower cost. 145 So why do I continue to use a Z80? probably because there is far and 146 away more software available for my needs that needs a 8080/Z80 to run. 147 **** MORE RAMBLINGS FROM CISTOP MIKEY **** 24 DEC 82 ************** 148 149 150 HOW ABOUT USING THIS SERVICE TO TRANSFER SOME REAL INFORMATION INSTEAD 151 OF REACTIONARY BULLSHIT.

THE 160 BEAVERTON ONE SEEMS WELL RUN AND HAS LOTS OF CAPACITY, BUT THEY DON'T 161 HAVE ANYWHERE NEAR THE NUMBER OF PROGRAMS THAT OLYCPM OR THE MISSAUGA 162 CPM IN CANADA HAS.

In fact, you will find a whole 168 section of the Beaver town RCPM dedicated to my programs. Admittedly, 169 the major share of them are from my AMODEM series. There are a number 170 of reasons for the current state of the system. The system is rather new, 171 and the CPM users group here is rather active. (Why waist time pulling 172 the program over the phone lines when you can go to a meeting and get 173 a copy free.) As a result only things that are of immediate interest 174 seem to get there. (This does not mean new, lots of old stuff there of 175 interest. I just pulled the Z80 resource off it myself recently which has 176 been around for a while, but I only recently had a need.) I kind of view 177 it as a remote data base for programs I may need sometime. (Why yank 178 stuff off it if I don't need it? I got enough full disks as it is!) 179 It is indeed a very neat system (as opposed to BWMS which is just strange!) 180 +++++ BY THE NEVER TO BE DETERRED CISTOP MIKEY +++++ 25 DEC 82 +++++++++++ 181 P.S.

Actually, the 800 appears the preferred model now. 222 64k, 2 joysticks, sealed unit. No expansion, no access. One cartridge 223 slot on side. Self diagnostics. 256 colors with 15 -count 'em - fifteed 224 graphics modes! (so the OS now supports ANTIC modes 4,5, and 15.) 225 One serial port, apparently not RS 232. 226 No mention made of printer port. 227 Memo pad mode eliminated. 228 Rest is cosmetics or minor features such as four function keys intended for 229 applications programmers to define in their software. Help key is RAM 230 vectored so programmers can do what they will with it. 231 More details in the PAC newsletter which went out today (Dec 28). 232 cu -- Pat 233 234 EXIT 235 236 One final holiday note -- BAH HUMBUG!! 237 238 239 SO aRATi will try to get us to buy another little piece of crap.

I would have lusted after the source but, alas, I 469 didn't see it anywhere. The .DOC is virtually the same as the 470 previous one except for a short preface about the small addition. 471 LASM shows you a running account on the console of each source 472 module as it's handled in both pass one and pass two. This is 473 convenient -- the only difference I have been able to detect 474 however. If it isn't on the Beav. RCPM, I'll try to put these 475 two files on the system. Also, I agree somewhat about Z80 vs 476 9900, 6502, etal. Actually, as someone who built an 8008 computer 477 in 1974, I may be hopelessly biased. But, I've never been THAT 478 impressed with the Z80 itself. The ZILOG architects paid a heavy 479 price for object code compatability with the 8080--if you look 480 at T-state specs on 8080 vs Z80 (as I did once again recently) 481 the preselector bytes take a heavy toll. And I bet there are 482 10 systems running straight 8080 code on the Z80 (ala CP/M-80), 483 NOT using the "full power" of the Z80 for every 1 system that 484 does use the Z80-unique instructions. I recently did some 485 calculations to investigate whether Direct Threaded Code (DTC) 486 had a performance edge over Indirect Threaded Code (ITC) on 487 the 8080. While doing this I also decided to compare using 488 the Z80 index registers in the inner interpreter of a FORTH I 489 am playing with (on a Z80 KAYPRO). I concluded that DTC had 490 a 20% performance edge over ITC and that, for the same clock 491 speed, the Z80 had only a marginal 2% to 5% edge over the 8080 492 subset architecture. True, there is simply more registers and 493 thus more flexibility in the Z80 but for some applications 494 (like threaded interpreters) the advantages don't seem that 495 compelling. Incidentally, for implementing threaded code, 496 the 6809 is far superior to the Z80. I wish Motorola had 497 brought out the 6809 at the same time as the Z80 had come out. 498 I would rather see a bigger audience now for the 6809. They 499 seem to have cought up somewhat with the 68000. Unfortunately, 500 market shares gained often overpower architectural elegance 501 for software developers. 1/4/82 - Adam Trent, Black Belt Programmer. 502 503 P.S. Still to Mike Day 504 Just called up the Beav. RCPM and sent LASM.DQC and LASM.OBJ to 505 it--you'll find them on A7--Wonder why "SECTION NEWPRGS" doesn 506 t work on the RCPM. - A.Trent 507 ******************************************************* 508 NOTICE.NOTICE.NOTICE.NOTICE.NOTICE.NOTICE.NOTICE 509 O C 510 T P.

If I get it disassembled 534 i'll let you know, and possibly put a copy on RCPM. 535 Thanks for the info. 536 ***** CISTOP MIKEY ****** 4 JAN 83 ********************** 537 QUESTION FOR THE TIMEX/SINCLAIR USER GROUP: IS IT TRUE 538 THAT IT TAKES A SHOOTING AND KEEPS ON COMPUTING??? 539 ********THE GREAT GAZORBAWITZ********1/4/83*********** 540 541 542 QUIT 543 544 545 546 ****************Calling Pat Warrenshuis!****** 547 My cheepo Signalman modem works beautifully. 548 I'll need to talk to you about doing some file uploads and 549 downloads Whose BB will take them? Any problem with 80 550 character wide files? Call me or leave a message on BWMS. 551 Golly gee whiz this is neet!-dan h. xxx-xxxx 552 ** to BIG DAN from Pat Warnishoeiss** 553 Glad you like the micromodem. Eugene ACE people use many 554 of them an all are satisfied. If I did not anticipate BBS 555 use here, that's what I would have bought. Hayes is nice,h 556 though, except for price. 557 Next month is modem month as theme for PAC meeting. Please 558 contact Jim Stibik on CBBS so you can report your experiences 559 You're our only signalman that I know of. 560 We can download/upload using Jonesterm. If you do not have 561 Jonesterm, call me xxx-xxxx and we can probably figure a way 562 to download it to you. 563 Nice to hear from, BIG DAN!! 564 ....cu...Pat. 565 566 ************************************************************* 567 I never considered the Timex/Sinclair a real computer 568 since it can't think and display at the same time, 569 but if the forgoing anouncement was placed there 570 using the timex/Sinclair, I might be inclined to 571 change my mind. ??? 572 ********************************************************* 573 Who says the Timex/Sinclair can't think and talk at the same time? 574 (Chewing gum at the same time by the operator is anouther mater thou.) 575 You are probably thinking of the ZX80 of which this was true (unless 576 it has the 8K basic ROM upgrade in it.) What the ZX81 does have is a 577 operation mode which allows the display to be turned off to speed up 578 the computing, but at 300 baud this is hardly needed! In fact a lot of 579 the old ZX80's are running out there on the old 4K basic ROMs with 580 simultaious display via a special program mod (They move the display 581 routines into RAM where the program can get at and use them.) 582 *** AN OLD ZX80 USER *** CISTOP MIKEY *** 5 JAN 83 ************** 583 P.S. I don't have it any more, I gave it to my dad. It was a nice play 584 toy, but I really didn't have any use for it. I do have a TINY WUMPUS 585 game written for it that runs within the 1K of RAM. (It eats into the 586 display RAM a bit, but runs ok I will) If anyone is interested I will 587 put a copy of it here. 588 **********************************************************************
