In reference to a recent posting about transwarp cards: I have a few, also, and you should be warned that the Apple IIe powersupply may overheat, since the transwarp draws a lot of current. This is especially problematic if you have a number of additional cards. There was a posting to the net not too long ago suggesting to replace the Apple powersupply with a JDR or Jameco. (cost about 50$, procedure very simple). This does indeed clear the problem (whereas a system-saver fan alone may not do the trick). So: be warned, and count on having to spend the extra money if you install one of the accelerator cards.

In summary: with 5 cards in the IIe (no Transwarp, but another accelerator and 2 ramdisks), they have been unreliable. Not only have some been dead on arrival, but I don't think any of them lasted more than 12 months.

My experience with TRANSWARP cards in ][e that are also equipped with a serial card, parallel card, mouse card, RamWorks (1 MEG), is that the original Apple ][e power supply was, and is, fine in two cases, but couldn't hack it in a third. For this one, a Applied Engineering power supply was put it (perfect fit, 5 minutes). It run the TRANSWARP, two serial cards, a clock card, and a RamFactor (1 MEG), which is **really** a power eater, quite nicely. Conclusion: Try the TRANSWARP first with your original power supply, unless you have reason to believe it's already marginal. Bruce P. Halpern halp@tcgould.tn.cornell.edu HALP@CRNLTHRY.BITNET

Applied Engineering sells a 5-amp power supply for about $50. This will provide ample amperage (didn't mean to alliterate) since the original power supply was designed for only about 1.2 amps (I think). Please reply via e-mail instead of the net.

Specific subject: REPLACEMENT POWER SUPPLIES FOR APPLE ][e I installed a Applied Engineering replacement power supply in an enhanced Apple ][e when an Apple Super Serial Card, another serial card, and controllers for 5.25" and 3.5" disks, plus Applied Engineering clock card, Transwarp, and RamFactor (getting most of its power from a RamCharger) proved to be to much. The Applied Engineering power supply was easy to install, fit perfectly into the space of the old supply, completely solved the power supply problem, and has been fully reliable. Bruce P.

In my last post about the Zip Chip, I wrote "it won't interfere with peripherals -- the major problem with Transwarp." I have received some messages from satisfied Transwarp users. In general, the Transwarp seems like a fairly reliable piece of equipment. There have been letters published in "Open Apple", though, about flakiness caused by the Transwarp card. In one letter, someone was having problems with Transwarp and a mouse card. Either card would work if the other was not in the machine, but they wouldn't work together. In the 3/87 issue (page 3.87), one user, who used a Transwarp along with a Checkmate card with 768K, said that three copy-protected disks were destroyed when he tried to disable Transwarp by pressing escape during booting. Tom Weishaar replied that he was having some strange problems with Appleworks, and when he replaced his Transwarp card with a Speedemon card, the problem disappeared. Mike Wertheim

I can't comment on Checkmate cards, since none of my ][e have them. All have either RamWorks or RamFactor. Several have Apple mouse cards. No problems have appeared with the mouse and AppleWorks (SuperMacroworks or Timeout enhanced), Beagle Graphics, ProSel, or MousePaint. Haven't yet given DazzelDraw a serious workout. I'm not a very sophisticated user, however. There may be problems that a demanding programmer would encounter that I would never see or notice. ****DISCLAMER: My comments, etc., are my own shakey opinions ******** | Bruce P.

I have a Transwarp card installed in a //e along with a mouse card, the Sider controller, floppy disk, RC Systems Slotbuster II, the 80 col card, and sometimes a serial card (SSC). My problem is that some programs in Hi-res graphics mode get little blips on the display screen. The entire 8 bit pattern on the screen is cleared even tho the byte read from that particluar location will say it should be $FF. An attempt to clear it to 0, and then store $FF again will lite it up. This only happens when the transwarp runs at fast speed and the Slotbuster is installed. For those who dont know, the Slotbuster performs multi functions of Parallel port, serial port, clock (opt), and speech synthesis. Does this also sound like a power supply problem? I do have a fan, but just the old power supply that came with it. It is enhanced //e (1984).

One of them was quite good, actually. Whoever wrote it made no technical errors and it included the kind of address specific info that one would expect (in particular, it gave a memory map of the alledged new "400x[320/640]" modes). It made good reading and it may indeed turn out that the IIGS+ fits the description (if the IIGS+ ever materializes) but there is NO PROOF of ANY of it being true. While I'm sure we all enjoyed the first few rumor files I suspect that they are beginning to aggravate a number of people. Until there is some substantiated information I suggest that we keep this kind of nonsense off of the net. ...and I thought my .sig was long. Really, Jason, that is too much. Lose the border and I think you'll keep Lord Morgan satisfied :-). My .sig looks really long but that's only because I squeezed everything together to save bytes... (remember, spaces and border take up just as much space as real info) ----the Second part---- >The ideas that software must "require" 7 MHz to produce sales of an >accelerator board, and that AE should produce such software, are off the >mark.

You are right, of course, when you say that it still may be worthwhile to get the card to enhance current software.
