- Summary: DayStar Digital has announced the development of an
- SE/30-specific version of their PowerCache accelerator that
- plugs directly into the SE/30 motherboard, leaving the PDS
- slot free for video boards, ethernet cards, etc.
-
- This article compares the features of the DayStar SE/30 PowerCache
- with two other multi-card upgrade options for the Macintosh SE/30.
- It's long; save a copy and pass it along to other SE/30 users.
-
- Background:
-
- In February Jon Temple and I began collecting names of people
- interested in 2-slot upgrade options for the Mac SE/30, hoping
- to convince developers that a market existed for such a product.
- The only existing option at that time, a NuBUS expansion box,
- did not support NuBUS accelerator cards (Radius Rocket) for
- use with the SE/30.
-
- One vendor expressed an interest: TSI Systems, who sell an '040 card
- based on Fusion Data Systems' TokaMac accelerator. They developed a
- prototype, but the project was abruptly cancelled in May '92.
-
- Meanwhile, there were rumors that DayStar Digital had done some
- custom installations of its Universal PowerCache in SE/30s,
- mounting the board in a socket on the SE/30 motherboard
- (as had been done for IIcx Macs with socketed CPUs). This
- rumor was confirmed by Leo Breebaart (thanks!) in mid-June,
- and a call to DayStar's product manager provided the details,
- accompanied by a request to keep quiet until an official
- product announcement could be prepared for MacWEEK, et al.
- (Six weeks lead time for a weekly trade magazine ... sheesh!
- Whatever happened to investigative journalism?)
-
- But enough background info ... here is the latest on the DayStar
- SE/30 PowerCache, followed by a discussion of the features of two
- other SE/30 expansion options, with some answers to questions
- originally posed by netters who wrote to request further info.
-
-
- *********** DayStar SE/30 PowerCache Leaves PDS Slot Open ************
-
- The following is an excerpt of a product announcement from DayStar Digital,
- containing technical informational, pricing, and expected release date
- for a new line of accelerator cards for the Macintosh SE/30. The excerpt
- was transcribed from a news release fax (typographical errors are mine)
- and is posted on July 21, 1992 in accordance with the "Please hold until
- week of July 20th" instructions given by DayStar.

- DayStar Announces SE/30 PowerCache
- New Version Leaves PDS Slot Open
-
- July 21, 1992 - Flowery Branch, Georgia
- ---------------------------------------
- DayStar Digital, a leading provider of high-performance hardware products
- for the Apple Macintosh, today announced the SE/30-specific version of the
- PowerCache accelerator. The new SE/30 PowerCache (33, 40 or 50 MHz
- speeds) provides the same performance and compatibility as our award-winning
- Universal PowerCache. Unlike the Universal model, however, the SE/30
- PowerCache leaves the PDS slot open for video or Ethernet boards. The new
- SE/30 PowerCache can only be used in the SE/30, but under DayStar's unique
- Swap-Up Program, users can swap the card for the same speed Universal
- PowerCache at no charge.
-
- How It Installs
- ---------------
- The SE/30 PowerCache attaches to the SE/30's motherboard, leaving the PDS
- slot free for video or Ethernet expansion cards. To connect to the mother-
- board, DayStar relies on a processor socket instead of the often-troublesome
- clip-on type of connector. For SE/30's with soldered processors, DayStar
- provides free socket and PowerCache installation with a number of return
- options designed to meet the users' needs.
-
- Availability and Pricing
- ------------------------
- The SE/30 PowerCache will be available <in August 1992>, exclusively
- through dealers and distributors worldwide. SE/30 owners with the
- Universal PowerCache can swap their accelerator for the new SE/30
- PowerCache at no charge.
-
- Suggested Retail Prices:
- -----------------------
- 33 MHz SE/30 PowerCache $ 699
- 33 MHz SE/30 PowerCache with 68882 math chip $ 899
- 40 MHz SE/30 PowerCache $ 899
- 40 MHz SE/30 PowerCache with 68882 math chip $1099
- 50 MHz SE/30 PowerCache $1399
- 50 MHz SE/30 PowerCache with 68882 math chip $1699
-
- About PowerCache
- ----------------
- PowerCache is a second-generation CPU accelerator that comes in 33, 40
- and 50 MHz speeds. It combines the power and reliability of a 68030
- processor and a superfast 32K static RAM cache to offer performance gains
- of up to 300% -- that's Quadra-level speed. An optional math chip speeds
- up math/science applications and spreadsheet recalcs 500% or more. All
- models of PowerCache are 100% compatible with all hardware and software
- while running at full speed. The Universal PowerCache, with its unique
- PDS design, supports eight different Macs, including the LC, LC II, SE/30,
- II, IIx, IIcx, IIsi and IIci (simple adaptor is required for all non-IIci
- installations). All PowerCache models are upgradable to DayStar's
- next-generation, 68040-based accelerator.

- ***************************************************************************
-
- The following discussion of SE/30 upgrade options is based on vendor's
- product info and phone interviews with marketing and tech support types.
- Standard disclaimer applies; I've tried to be accurate, but I recommend
- that you check the facts -- particularly with respect to compatibility
- with other hardware and device drivers -- before you buy one of these
- products.
-
- Upgrade Options for the Mac SE/30
- ---------------------------------
-
- SE/30 owners now have three distinct hardware upgrade paths:
-
- * Second Wave Expanse NB4 and NB8 (4 or 8-slot NuBUS expansion chassis)
- * Aztech Galexa SE30 Slot Extender (modular Mac kit with 2 PDS slots)
- * DayStar Digital SE/30 PowerCache (accelerator card leaves PDS free)
-
- With the introduction of the SE/30 PowerCache, DayStar Digital has
- provided an inexpensive upgrade option that meets the needs of the
- great majority of users who want to add both video and accelerator
- cards to their SE/30s. Second Wave and Aztech offer a few unique
- features of interest to users with specialized needs.
-
- Form Factor and Features
- ------------------------
- The DayStar SE/30 PowerCache adds no external hardware to your
- SE/30; it is a very small PC board (maybe 8 x 15 cm) that is
- socket-installed by DayStar (yes, you'll have to ship your Mac
- to Georgia) onto the SE/30 motherboard. Given DayStar's pricing
- and liberal trade-up policy, the 'second slot' is essentially free
- for SE/30 users who have already decided to add an accelerator card.
-
- The Aztech 'Galexa SE/30' is comes in form of a kit that lets you
- (or Aztech, of course) build a modular Mac using your existing SE/30
- motherboard, floppy drive, and hard disk. The kit includes a new case
- with room for 2 HDs, 65 watt power supply, FDHD drive, and two PDS slots.
- Because the original case and internal monitor are unused, this option
- requires that one of the PDS slots be used for a video card. The resulting
- modular Mac looks much like a IIcx or IIci. The Aztech option is probably
- of greatest interest for SE/30 users who need an extra PDS slot, but don't
- need an accelerator card -- color monitor plus ethernet, for example.
-
- The Second Wave Expanse NB4 (or NB8) have 3 hardware components:
- an external box (25 x 55 x 10 cm) with 50 W power supply, PDS
- interface card, and special (read expensive) interface cable.
- One of the 4 (or 8) added 10 MHz NuBUS slots can be used for NuBUS
- video (for example, a MaxAppleZoom-compatible Toby frame buffer).
- The others can be used for any number of NuBUS cards, with the
- unfortunate exception of the only currently available NuBUS
- accelerator card, the Radius Rocket (all versions). The Second Wave
- option is probably of greatest interest to two kinds of Mac users:
- first, institutional users whose budget policies make upgrades
- easier to obtain and/or justify than selling an old computer
- to buy a new model, and second, users who need specialized boards
- for data aquisition and control (or extra serial ports) that
- are much easier to find (and pay for) in NuBUS form.
-
- Cost
- ----
- Cost is the bottom line when considering an upgrade. I happen to
- like the 'classic' compact Mac form factor, and the second screen
- of an SE/30 with an external monitor can be useful, but I wouldn't
- pay more than the price of a comparable modular Mac to upgrade.
-
- To calculate a reasonable upgrade price, I've used Spring '92 prices
- from Maya Computer, a company that sells (or used to sell) used Macs.
-
- Resale price of used IIfx 4/80 $ 4069
- Resale price of used SE/30 4/80 - $ 1549
- --------
- $ 2520
-
- The IIfx provides a good basis for comparison; DayStar's suggested
- retail price for a 40 MHz CPU/FPU version of the SE/30 PowerCache
- (to match the 40 MHz CPU and FPU in the IIfx) is given above as $1099.
- The current MacWareHouse price for the Universal PowerCache plus
- SE/30 adaptor is similar, so the same accelerator cost is applicable
- for users who prefer the modular Aztech Galexa SE/30 option.
-
- The prices above exclude keyboard, video cards and monitors; note also
- that the IIfx has faster SCSI and 6 NuBUS slots, while the SE/30 has the
- option of built-in video and monitor and one (precious) PDS slot. Users
- will have to decide if the difference is worth $2520 - $1099 = $1421,
- but I think it's clear from this example that the SE/30 with DayStar
- PowerCache is worth considering.
-
- The other SE/30 upgrade offers are significantly more expensive.
-
- The Aztech Galexa SE/30 kit costs $695, and requires the user to
- provide a PDS video card and monitor (another $650, at least).
- The total cost with a 40 MHz '030 accelerator plus FPU (excluding
- video) still beats the used IIfx by at least $650.
-
- The Second Wave Expanse NB4 for the SE/30, including 4-slot NuBUS
- expansion chassis, SE/30 interface card, and 2 foot cable, sells for
- $1295 + $595 + $125 = $2015, according to a Government/Education
- price list (dated Oct. '91, but provided recently by Second Wave).
- This price was quoted prior to the Aztech and DayStar product
- announcements, and thus may become more competitive in the future.
- Accelerator cards don't work with the NB4, so the upgraded SE/30
- vs. used IIfx comparison doesn't apply.
-
- Compatibility
- -------------
- The DayStar PowerCache requires an init/cdev that lets the user
- toggle both CPU and optional FPU between accelerated and normal
- modes (at least in the case of the Universal PowerCache). An init
- at least would be also be required for the socketed SE/30 PowerCache.
-
- By all accounts, the DayStar accelerators provide excellent
- software compatibility -- better even than the Quadras which
- must run some older software with the '40 cache disabled.
- The 32K static RAM cache included with the PowerCache card
- should be compatible with all Mac software.
-
- Still, any hardware device that requires an init to function
- properly runs the risk of incompatibility with somebody's
- indispensible 3D "BlinkyTrash" extension. (One might think
- that someone willing to spend big bucks on an accelerator
- could live without toys, but then, I've found some pretty
- silly inits in the System folders of otherwise-sane Mac users
- who just happen to like computers that are fun.)
-
- Badly-written software that is timing-dependent can break on
- accelerated Macs. I haven't heard any reports of this with the
- PowerCache, but old games and sound-using apps may be problematic.
-
- My own experience with the DayStar is limited. So far,
- I've run the 50 MHz Universal PowerCache on an SE/30 17/200
- under System 7 and A/UX 3.0 without problems. The SE/30 adaptor
- card shipped with a copy of Connectix MODE32, and the PowerCache
- control panel shipped on a disk containing System 6.0.7. System
- versions including System 6.0.7, System 7.0 in 24 or 32-bit
- modes, and A/UX 2.0.x and 3.0 are explicitly supported in the
- installation manual.
-
- The Aztech Galexa SE/30 was still in testing when I talked with
- their tech support person. It will probably include an init
- of some sort to handle the possibility of a multiple PDS cards;
- prospective users should make sure that their specific combination
- of cards and driver software have been tested by Aztech before buying.
-
- The Second Wave NuBUS expansion box most likely requires a software
- component to drive the interface card, but it wasn't mentioned in
- the product literature. The good news is that if the slots work,
- conflicts between add-in boards should be no more likely than with
- any other Mac with NuBUS slots. Once again, call Second Wave with
- compatibility questions if your application requires a specific card.
-
- The Bottom Line -- Analysis and Opinion
- ---------------------------------------
- I've already taken the plunge, so I'll warn you: I'm biased.
-
- The Second Wave NuBUS expansion chassis doesn't make sense as an
- SE/30 upgrade. Without the possibility of adding an accelerator
- card, it would be better to sell the SE/30 at a significant loss
- and pick up a used Mac II if you need the extra NuBUS slots.
-
- The Aztech Galexa SE/30 kit was big news for me, two months ago,
- because it was proof that someone else had taken up where TSI
- had left off with their cancelled 2-slot adaptor card. I was
- impressed after talking to the company president, who spoke
- knowledgeably about technical aspects of Mac hardware -- and I
- dashed off an article proclaiming that the 2-slot problem was solved.
- I was disappointed when a fellow netter pointed out by e-mail that
- the Aztech Galexa upgrade came in the form of a modular Mac kit.
- Somehow, this point never came up in a half-hour conversation with
- Aztech's president, in which I specifically asked about the Aztech
- "2-slot adaptor" that I'd heard about.
-
- The Aztech upgrade does offer the possibility of two internal
- SCSI drives and otherwise unobtainable PDS board combinations.
- Even at $695, the Aztech kit plus a 40 MHz accelerator is cheaper
- than a used IIfx in the example given above. It's the only upgrade
- path for SE/30 users who have already purchased non-DayStar PDS
- accelerator like the Magellan 040 or Fusion Data Systems TokaMac.
-
- That leaves the DayStar SE/30 PowerCache ...
-
- I'd waited months for a 2-slot upgrade option, and resisted the
- temptation to buy various accelerator cards to avoid being locked out
- if somebody finally "did it right". As soon as I learned about the
- DayStar SE/30 PowerCache -- and DayStar's offer of free same-speed
- trades for Universal PowerCache owners -- I went shopping for a 50 MHz
- accelerator plus FPU. If I decide that I need an '040 accelerator in
- the future, DayStar plans to offer the same liberal trade-up deals
- when they release their expected 40 MHz '040-based PowerCache.
-
- Another point in favor of the DayStar option is that it didn't
- commit me to a particular video card; in fact, I can't afford one
- at the moment. It gives me the option of upgrading by increments:
- first a Micron Xceed video card with internal grey-scale adaptor,
- then later on perhaps I'll be able to add an external monitor.
- The Aztech upgrade would force me to make that decision now.
-
- Finally, I get to keep my classic, compact, luggable Mac. Until
- they find a way to make PowerBooks that can run A/UX, the SE/30
- can become the fastest, most versatile (runs MacOS, Unix, and DOS)
- "transportable" computer that money can buy. Not bad, huh?

- Acknowledgements: At last count, 110 netters had responded
- to our request for names of SE/30 owners interested in 2-slot
- upgrade options; thanks to those who suggested questions for
- the board manufacturers. This "list of 110 potential buyers"
- was mentioned (and even exagerated) freely by both Jon Temple
- and I in our dealings with the various companies involved,
- and seemed to generate interest, even though we never used it
- for anything but e-mailing copies of follow-up postings like this.
- Hopefully the resulting net.noise generated a few extra phone
- inquiries to marketing people, and helped keep the wheels turning.
