  1. I am unsurprised that your Amiga flickers but I am happy that it works in Mac mode.
  2. The 16 bit memory bus and 10MB RAM limit (LC and Classic) were almost certainly marketing decisions. Here are some UK education prices for Macs in their lowest spec: LC I 2/40: £1065; IIsi 2/40: £1606.50; IIci 5/40: £2726.50; IIfx 4/floppy: £2927 Classic I 1/floppy: £490; SE/30 2/40: £1556.75 Third party developers had previously used bits from the Plus and SE (even just ROMs) for creations such as MacColby, Dynamac, Intellitec MX Plus, Outbound (and a few more). The LC and Classic families therefore needed to be functionally limited to discourage third party developers. Let's ima
  3. Thanks, techknight, for the background info. But returning to the OP's question, what is the best way to run a CRT monitor? My understanding are that there are two failure modes: the CRT itself (requiring a CRT swap) and the associated circuitry (which is fixable, at a cost of time and parts). Manually switching on and off will increase wear and tear; but don't the AV monitors have a basic power saving function that will cause similar problems? Assuming the OP can find somebody locally to repair boards (ie replacing components subject to cycling), switching on/off would extend CRT life?
  4. From my notes on the Turbo601 board: DayStar's Turbo 601 accelerator was designed for "any" Mac with a logic board with a IIci cache slot (IIci, IIvx, IIvi, Performa 600). The IIsi with a suitable PDS slot adapter was also supported. The Turbo 601 was sold at two speeds, 66MHz and 100MHz. According to Low End Mac, different part numbers were assigned to the three variants of the board (IIci, IIsi and IIvx/IIvi/Performa 600). Unfortunately, the variants are not visually identifiable -- there are no labels that state "This is a IIci board" or "This is a IIvx/IIvi/Performa 600 board". Us
  5. Do you have a strategy for converting MacWrite Pro files into more modern formats? If you wish to use Zip drives. you'll need two: a SCSI model for the SE or SE/30, USB for a later Mac. If you can find an Ethernet card for either old Mac, wired file transfers are best done by FTP. It's a bit clunky but it is how professional publishing was conducted in 1995. In 2015, you have to configure an FTP server and related ports (on whatever hardware) to talk to an old Mac; it can be done safely. ** Edit If we are expected to deliver good advice, tell us more about what you are trying to achie
  6. And the packaging and the manual... Many Americans do not understand "the rest of the world". So when considering Apple II variants, we have to think about the Apple J-Plus. The J-Plus could present Japanese text on screen. But it wasn't Japanese text that most Japanese could read.
  7. For the IIgs, you need a colour monitor for games (or GS/OS which is great). You need a 3.5" 800KB external floppy. If feeling rich, you'll fall for mass storage -- a SCSI card or modern alternative. It's an expensive change.
  8. There is no need for apology. I've bought great stuff because it was interesting. Few of us proclaim our failures. * I've bought two early Apple IIs which turned out to be crappy clones. That's fine. I have expensively boosted my pool of Apple II spare parts. * I have bought disappointing Mac accelerators or graphics cards for my vintage Macs. But, caveat emptor, lots of computers have interesting internals, and you never know...
  9. So it's an ISA card made in 1987 by ...itech using a chip from Logitech. In 1987, the Apple network players were Tri-Data Netway, Farallon and Tangent. Have you just mistaken a mouse card for a LocalTalk network card?
  10. You'd be amazed at some of the kit on offer in the UK at a discount in the 1990s. Twin floppy LCs? The SE/30 was available on education lists at full price for months after it was discontinued in the USA. The twin floppy LCs were discounted a bit but they were ridiculously overpriced. I reckon that they were for sale but that dealers held no stock. I doubt whether Apple dumped any SE/30s. LCs and Performas that weren't any good were rejected by the market. Good Macs were bought. The Colour Classic II wasn't very good. Desktop Macs used 68040 processors and were heading for PPC 601 proc
  11. You must have a battery or a dummy installed. Also change the secondary 9V PP9 battery. About power supplies: The original power adapter (M5136) for the Portable provides a modest output -- 1.5A at 7.5V, a nominal 11W. The adapter's output is not sufficient to recharge a heavily discharged battery and to run the Portable simultaneously. The PowerBook 100 power adapter (M5140) provides a nominal output of 15W and is more effective at recharging heavily discharged Portable batteries. Later PowerBook adapters provide outputs that are too great to use safely with a Portable. The Portable m
  12. You have to press the "Any" key From my notes: The limited intelligence of the power management unit PMU) is a major annoyance. The PMU may refuse to boot the Portable even when all components are fully functional. Even when fitting a fully charged battery, the PMU may require occasional resets, so make them a regular part of your diagnostic routine for the Portable. Later desktop and portable Macs have better PMUs which do not require such frequent resets. My preferred method of resetting the Portable PMU is a bit more thorough than the one described by Apple: 1. Shutdown the P
  13. Agree 100%, Trash. It's time for the OP to run some software probes/diagnostics. Formac had a few mentions in UK Mac magazines in the 1990s but I don't have many. MacUser UK 6 Jan 1995 mentions an older accelerator for the LC family. It was the Formac Pro 50 (68030 50Mhz). Formac had a straightforward naming convention. ProNitron = Trinitron monitor. ProDrive = SCSI HD. ProGraph = PDS graphics card. ProOpt = SCSI MO drive. ProVision = PCI graphics card. ProLegend = NuBus graphics card.
  14. No. Let's understand that we are talking about 68K accelerators. And about PDS slots, which are substitutes for the native processor. Accelerator boards tell the on-board processor to close down. No drivers required in the 68030 world.
