actually be ready until <strong>1993</strong>!), Crystal City (classic spaceshoot ‘em up), and Zenix (similar to original space invaders,but much more action!). All of these games featured superiorgraphics, sound, and animation, especially when viewedon an RGB monitor. Burke&Burke had something new forOS-9 users- a speech synthesizer called Cyber Voicewhich used a SC-02 synthesizer chip.The December Rainbow has Lonnie squelching rumorsof the Rainbows demise. He states that "There is nointention, plan, idea, concept, or anything of the kind tocease publication of the Rainbow. I don’t know howthese rumors get started." Well, one way is the shrinkingsize and number of advertisers (still 98 pages, 47 advertisers).He reassured readers that there would be a Rainbow forsome time, and that there would be a spring 'fest in Chicago."Some time" was still two and a half years away... Manyreaders complained about no rack seller availability. Thiswas due to cutting back the number of rack sellers. Why?Rainbow actually took a LOSS on many single-issue salesdue to support of many locations that only sold a few copiesmonthly. Only those outlets with good sales would besupported from then on. Perfect time to save money and geta subscription! A new version of the Slot Pack, Slot Pack III,was introduced by Howard Medical. A hardware switchwas added to allow use of most ROM packs in slot 1, a legadded to support the pack, faster buffer chips used, and anexternal power supply became necessary, as the drawfrom the CoCo was just to much.If you have ever considered recording CoCo screens onvideo tape or using some of the CoCos abilities in yourhome movies, then do get a copy of the December 90 issue.An article by Mark Haverstock and Bill Wills shows how.An article by Andrew T. Boudreaux, Jr., tells how the NewOrleans CoCo Users Group made a show on the CoCothrough a local cable community access channel. Thegroup even used their CoCos for several required functionssuch as headers, title screens, and prompters. It’s here-CoCo TV! A new CoCo book was reviewed this month."Connecting CoCo to the Real World" was written byWilliam Barden, Jr., a Rainbow contributing editor. Thefocus was on connecting the CoCo, mainly through thejoystick ports, to many items. Projects included a burglaralarm and weather station. If one can find the book it is veryinteresting and the projects pretty easy to build. Unfortunately,Mr. Barden left the CoCo community shortly afterreleasing the book. Worse, he seems to have left on a sournote... or at least left some CoCo users who ordered his bookthat way. The author was one of several who ordered the bookand never received it, yet had their check cashed. Inquirieswere left unanswered. Luckily, few CoCo vendors, who relyon mail order, leave us in this manner... most are VERYreliable! Who would have thought this of Bill? If there wasextenuating circumstances unknown to us I apologize inadvance for including this here, but we who ordered were atleast due an explanation, and a refund. And sadly, yet anotheradvertiser falls out as the last Second City Software adappears. But take heart! They aren’t leaving the CoCo market,just moving operations and changing name to KalaSoftware. Unfortunately, Rainbow ads won’t be in the "new"companies' future any time soon.Hardly anyone noticed that the last Computer Island adappeared in the October ’90 issue of Rainbow. Nor that thelast article written by Steve Blyn (a contributing editorsince July 1982 with his Education Notes column) appearedin November. This was brought to their attention byLonnie Falk in the January 1991 issue. Steve wrote a verygood letter explaining that orders were slow and the operationwas winding down. Lonnie publicly thanked Steve andhis wife Cheryl for the many contributions to the CoCocommunity and wished them luck... from ALL of us! In thiscase, Lonnie definitely spoke for at least most longtimeRainbow readers. Well, at least there is some good news, asthe first ad from Rick's Computer Enterprises appears.Several programs are offered, but the most interesting isThe Rainbow Indexes, a database of all Rainbows since theoriginal and promised to be updated annually. Now if oneneeded to refer to an old article, simply boot the program andsearch! No more thumbing through the anniversary/indexissues! Thanks Rick, we needed something like this!Not all was doom and gloom in January! Zebra <strong>Systems</strong>introduced First Prize, an award certificate making programfor the CoCo 2 or 3. This useful program came on SIXdiskettes, complete with storage box! Like other Zebrasoftware, First Prize operated in an easy to use point andclick graphics environment. CoCoPRO! came through thefest with some leftover Japan scenery disks, Flight Sim II,OS-9 Level 2, and Marty’s Nightmare games. Those whodidn’t attend the fest were now able to purchase thesebargains. The IMS ads featured an interesting twist: an MM/1 could now be purchased as a kit (add your own case,keyboard, monitor, and drives) for $659, a savings of $120.One reason for the kit was delays in meeting FCC requirementsfor full systems, which was causing seriousdelivery delays. Many people who had made down paymentswere wondering if they would ever get anything! Kits couldbe sold without FCC certification. Delphi users wouldnotice lower rates in their ad ($6/hour), and also discoverthat Marty Goodman is the CoCo SIG manager! And whatis that on page 33? A System IV computer from DelmarCompany! I remember! This was a THIRD 68xxx based,OSK computer system which first came to light at theAtlanta CoCoFest, which was only fitting, since PeripheralTechnologies of Atlanta builds the boards! These machinesused a 16MHz 6<strong>80</strong>00 chip and a PC/XT 8 bitexpansion bus. The PC/XT bus was used due to the availabilityof cheap expansion cards. A base model with four serialports, a parallel port, 1.4MB 3.5" floppy drive, 40MB harddrive, case, keyboard, OSK operating system, and monochromemonitor sold for $1399. Delmar sold completesystems, kits were available directly from Peripheral<strong>Tandy's</strong> <strong>Little</strong> <strong>Wonder</strong> page 25
Technologies. This computer had been in existence forseveral years. It actually started as a build it yourself projectin an electronics magazine several years before.. sort of likethe original hobbyists computer- the Altair (anyone readingthis even remember one of those?).The ads were interesting in Februarys’ Rainbow. The firstthing one will notice was that longtime advertiser Microcomonly had two pages. Didn’t they ALWAYS have six before?Are they fading away also? The last Howard Medical andlast Dr. Preble's Programs ads appeared this month.Thanks go to Ross Litton (Howard Medical) and Dr. Preble(he was actually a Dentist!) for the many years of goodservice. The MM/1 had only two quarter page ads this time.Maybe the "new CoCo" isn’t doing so well after all... (previousads were one and two pagers). But here to save us fromall this gloom is the rising star of the CoCo community-CoCoPRO! New this month was an OS-9 version of Kyum-Gai, to be Ninja. Though many critics thought OS-9 was nota good environment for action graphic games, they wereproven wrong, as the two versions of Kyum-Gai were nearlyindistinguishable. There were only 30 copies of Marty’sNightmare left now... better hurry! Last but not least, Tandyannounced a CoCo "blow-out" sale on the back cover.CoCo 3s could be purchased for $99.95, CM-8 monitorsand single disk drive systems for $149.95.Marty Goodman told all about monitors for the CoCo inMarch. This was also the thinnest Rainbow yet- only 82pages! CoCoPRO! ads grew to 1/2 page. They offered TandyOrchestra-90 paks for only $17.95 (was $79.95) and "Wherein the World is Carmen Sandiago" for only $15.95 (was$34.95). Sadly, another supplier is lost as Danosoft runstheir last ad. Rainbow stopped shipping the magazine inplastic bags this month. Cray Augsburg said it didn’tsignificantly reduce complaints about mangled magazines inthe mail, but most subscribers realize it was mainly a costcutting measure. Better the bag than more pages!A new serial pack was introduced in the April CoCoPRO!ad. It was a conversion of the Tandy 300 baud DC ModemPak, which contained most of the circuitry for a true serialport. The modification was designed by Marty Goodman.A completed pack or kit was offered. The company ad was upto a full page in May. Soft and hard ware from severalcompanies was brought on line. There were only 23 otheradvertisers. A new piece of hardware came to light in Mayalso the Delta Pro sound device by Lucas Industries 2000.The Delta Pro used the delta, or change, method of recordingsound. Digitized sound was now possible with minimummemory usage. H. Allen Curtiss’ desktop publishingprogram was updated beginning this month into Ultralace,which would run on the CoCo 3 only. The updates wouldoccur over the next several months, as the program wasalmost totally re-written to take advantage of CoCo 3 featuresand for higher resolution printing.page 26<strong>Tandy's</strong> <strong>Little</strong> <strong>Wonder</strong>April 26-28 was the time for the last Rainbowfest (heldin Chicago). Radio Shack took up almost a fifth of thefloor space! They were selling CoCo 3s for $<strong>80</strong>, OS-9Level II for $40, and lots of OS-9 based software for $5and $10! The final hours of the last day saw Tandy sellingCoCo 3s for only $60... guess they didn’t want to load themback in the truck! Many vendors were there showing theirwares, including the three OSK machines. Delmar and FHLdisplayed actual production models, while IMS still had aprototype. Developmental delays, including FCC certificationproblems, had delayed production. Many people wereupset, but they were continually reassured that the computerWOULD eventually come and the fact that the company wasshowing up at the 'fests at least let everyone know they stillexisted. Lonnie Falk moderated a question and answerseminar between Ed Gresick (Delmar), Paul Ward (IMS),and Frank Hogg (FHL) concerning the three OSK machines.Seems that interest in these "new" machines is prettyhigh. <strong>Wonder</strong> if I should consider making the switch? GuessI should try learning OS-9 on my CoCo first! Soon after this‘fest, Tandy started selling most OS-9 software, includingLevel II, the Development System (assembler), andC compiler for $5-$10 nationwide (they were let go atthat price during the fest also). Interestingly, Multi-Vuecontinued to carry a $49 price tag. These bargains werenot advertised, but once they were found out, things wentFAST! It was becoming hard to find CoCos and related hard/software in Radio Shack stores. The end had finally come.Many CoCo 3s were made before the Christmas season, andthere were plenty... to many... left. No more CoCos wouldever be produced.Careful readers should have noticed by now that there hasbeen no mention of OSK’er for five months. The reason isthat they mysteriously disappeared! The fourth issue finallyreached subscribers in May. Understandably, the editordecided to leave a date off the cover. In this case, thedirectory format of the table of contents comes in handy- theeditorial was last modified on April 23rd, 1991. Thislapse of coverage with no notice to subscribers was inexcusableand hurt the reputation of both the magazine and editor.The editor realized this, and wrote an apologetic editorialabout missing deadlines. It seems that a big reason for thelapse in issues was that the company (StG Computers)moved locations. He also stated that "OSK’er (was) backfor good". To bad that would not prove to be a truestatement. On the plus side, a good article on BASIC09(Introduction to BASIC09) appeared in this issue.It didn’t take one long to notice that there was no Microcomad in the June Rainbow! Last month it was SD Enterprises,distributor of the VIP series. Is one of the largest CoCosuppliers leaving? Lonnie lets us all know not to expect tofind Rainbow on many newsstands. These sales were neverhigh, but many were kept up because one could walk out ofa nearby Radio Shack with a CoCo and pick up a magazinethiswas now next to impossible. Only those stands with
