But the Macintosh itself was changing in 1987: the introduction of the Mac II broke with the all-in-one design which had characterized the computer since its unveiling in 1984. The new, modular architecture (and its multiple open slots) was expressed in a much larger case design — almost IBM PC-like in its dimensions. As a custom piece of furniture designed for Apple’s flagship, the MacTable would have to change along with it. Thus in September of that year Scandinavian Computer Furniture, Inc. announced that Denmark had re-thought the computer table — again:

Instead of the original, one-size-fits-all cutout for the original Mac lineup, the MacTable delivered a series of variously-sized surfaces that could accommodate anything from a 128k to a fully-loaded Mac II, all the while providing the variable tilt motion the original table was known for. Now,the angle of separate desktop cases, two-page displays, and other items could be adjusted the same way the original Mac could.

The company also proudly announced that they were even switching the color of the desktop laminate, from beige to “Platinum Gray, same as the new Macintosh line.” (This may be the closest that Frog Design’s “Snow White” design aesthetic ever came to expression in office furniture.)

MacWeek’s June 1987 “Snapshot” on the revised MacTable is the one of the earliest appearances of the new version in the press. At this point the company is described as ScanCoFurn, operating out of a Redmond, Washington address. The table itself cost $269, while the laser printer cabinet went for $129. The photo (shown above) depicts a relatively rare variant of the basic table, in black and white, which bore a higher price tag of $335 and a later ship date of late July. (I haven’t ever seen this type in the wild, and it was never mentioned in advertisements, so it’s hard to know if they’re very rare or were ever even produced.) The black-painted wood in the picture above is more in line with certain 1980s aesthetics, but loses a bit of the charm of the natural-beechwood finish that most people are familiar with in a MacTable.

Sun LaserWriter

Re-Badged Printer

As a kid I remember seeing a white LaserWriter with the distinctive SUN logo on it in a university computer lab, probably around 1987. Thinking back on that memory recently, I started to wonder what this odd output device was. Would Canon and Apple really have allowed Sun to re-badge one of their most important products? Or had some prankster simply put a spare SUN badge on the side of a standard Apple peripheral?

This is one of these questions is which is hard to Google, because of the age of the products involved. But it turns out the truth is exactly what I remembered: Sun sold a version of Apple’s laser printer, even calling it the “LaserWriter,” for use with Sun3 workstations. We can find a few mentions of this product starting in InfoWorld, December 1986 and continuing on to an Australian Unix Users’ Group newsletter in early 1987. Finally, the Spring 1986 BMUG Newsletter confirms “the exact same specs as the original Apple LaserWriter. It is meant to be a printer for the Sun line of computer workstations and communicates over an RS-232 communication port.”

The original Apple LaserWriter also had this RS-232 port, in addition to the serial/LocalTalk 9-pin DIN connector, so it’s possible that the Sun variant had the Mac-centric port as well. Either way, the printer I saw in 1987 was connected to an IBM PS/2 Model 60 (long story) which was doing print serving for a whole lab of PS/2 Model 30’s, so it would have gotten along just fine with the traditional serial port.

An intriguing glimpse into the market positioning of this Sun LaserWriter was the mention in the Australian journal of a bundled software package from Adobe called “Transcript.” Transcript turns out to be very hard to dig up information about, but it seems to have been a commercial troff tool, and thus would have been useful on SunOS workstations to prepare documents to send to the laser printer.

Anyone with a Sun-badged LaserWriter should take a picture and send it in…

Radius Full Page Display

Two screens are better than one

We often remember 1987 as the start of the era of external displays on the Macintosh. With the enormous size of the Mac II came expandability of six NuBus slots, as well as the software flexibility of System Software 2.0 (System 3.3/Finder 5.4) with the Monitors control panel.

We shouldn’t forget earlier options, however. The November 1986 issue of MacUser proclaimed “Bigger is Better!” and showcased an impressive — and expensive — add-on to the humble Mac: the Radius Full Page Display for the Mac 512ke and Plus. Wikipedia goes so far as to call it the “first large screen available for any personal computer.”

Looking at this picture you probably have two questions: How could this possibly have made sense financially? How could this possibly have worked technically?

Hardware

The second question is easy enough to answer. Radius was made up of ex-Apple hardware engineers, and they pulled quite a few rabbits out of their collective hat. The FPD used the security slot, of all possible things, to route the cable for external video out of the case. Notice the small video connector in the photo to the right:

This was was routed through the small security slot on the back of the classic Mac case. The Full Page Display interface sat right on top of the 68000 central processor, with additional connections to the FB1 and C35 resistors. Originally this internal card originally had to be installed in the Sunnyvale factory, and the process took a week to complete. An easier clip-on installation method was released in Q2 1987.

Permanent changes to the motherboard were also made. These presumably included the Radius ROM, which obviated the need for a special boot-up disk — a requirement of other vendors’ solutions. The integration between the Radius ROM and the Apple motherboard was evidently pretty deep: as an example, the larger PRAM in a Mac Plus allowed the precise vertical alignment between the tops of the internal and external screens to be memorized, but the 512KE had to be set manually at every boot time.

The Economics of Desktop Publishing

The financial question is more interesting. Who was spending $2,000 to add an external monitor onto a Mac Plus — let alone a 512KE?

The portrait display as a form factor, though gone from the market today, actually was quite popular in the late 80s and early 90s. The reason was simple: as the name implied, it could display a full 8.5×11 page on the screen at one time with its 640×864 pixels. This was in an era of Aldus PageMaker: Desktop Publishing was saving the entire Mac ecosystem (and arguably Apple) from being a footnote in computing history.

There are two interesting things about this FPD ad from 1988:

1988 Ad

Radius Full Page Display Flanked by a Mac and LaserWriter (InfoWorld)

The first is that the LaserWriter Plus flanks the monitor to the left: Radius envisioned the FPD as an essential part of a complete DTP setup. The second is that there’s a humble classic Mac to the right. Even in 1988, when the Mac II had been shipping for a while (notice the picture of that expandable machine lower in the ad copy), Radius still saw a market in upgrading Classic Macs with external displays for the Desktop Publishing market.

The Shock of Multiple Screens

At 15″ diagonally, the FPD had nearly the same 72 dpi pixel density as the Mac CRT, a big selling point. In fact, Radius was the only player in this nascent market who could actually both screens at the same time. Other vendors, including E-Machines and Micrographic Images, shut down the internal screen completely. This simultaneous use of both workspaces, which we all take for granted today, was as revolutionary as capacitive touch was in 2007. “As the mouse reaches the right- hand edge of the Radius, the image suddenly appears on the Mac’s screen, jumping right across the gulf between the two machines,” gushed InfoWorld. “This behavior invariably startles people the first time they see it.” Here’s Stewart Cheifet being startled this feature during a demo by Radius co-founder Mike Boich on Computer Chronicles:

“That’s pretty impressive!”

Of course, application compatibility was hit-and-miss. Even an app as canonical and central to the Macintosh as MacPaint wasn’t written to take advantage of the greater screen space. Excel would crash if you made the window too large, and MacWrite wouldn’t properly redraw the screen after formatting changes which extended off the original 512×342 pixels. Updates fixed some of these problems, but there was a reason that Radius demo’d the screen with T/Maker’s WriteNow: it was written according to the guidelines in Inside Macintosh and worked well. Raines Cohen, co-founder of the Berkeley Macintosh Users Group, saw the display at MacWorld Boston 1986 and noted “The Finder doesn’t know about the Macscreen, but can use the entire Radius.  MacPaint doesn’t know about it, of course; FullPaint does, sort of, I think… SuperPaint will let you put your pallette at top of the screen to take advantage of MOST of the screen.  ComicWorks is the best; it lets you put your tools onthe Mac screen & dedicate the whole page to graphics.”

Blazing a Trail with Software

The reason for all these problems was simple: the FPD shipped well before official support for multiple displays and the accompanying Monitors control panel (which wouldn’t have appeared on the Plus and previous models anyway). Thus Radius had to write their own software to manage this radical peripheral. Larger cursors, a screensaver, double-height menu bars, and other magnification features debuted here, to be further developed as Radius shipped countless color cards for NuBus in the years ahead. Radius even programmed an extension to add Zoom button to the top-right corner of Mac windows which lacked them. Cohen: “Andy’s software teaches most applications to have a ‘zoom box’ (like MacDraw), and cmd-zoom will zoom a window to the full Mac main screen.”  The Mac’s screen capture feature also had to be re-written, and even Radius’ own feature only grabbed 90% of the large screen. This software consistently earned rave reviews, and probably explains the leadership position which the company had in the external display market into the 1990s.

The FPD cost $1,995 retail. And for all that money, you only got a 3-month limited warranty!
