The System 7.5.3 download originally made available by Apple was actually one single segmented self-mounting image, and did not use a separate Disk Copy utility. For example, the North American version was provided as nineteen separate floppy-sized segments. Each file was protected by an...

Which system version on the LC(s)? StuffIt Expander? Any chance of transferring/downloading files to the LC(s)? Without access to a PB 190 Disk Tools floppy, a Disk Tools PPC...

First of all, just to clarify, the original (perhaps 500 MB or so) IDE hard drive contains a working operating system (which version?) and can boot? If so, you could buy a PC Card adapter for CompactFlash and something like a 0.5 to 2 GB CF card. Then, boot the PB 190 from the original hard...

Yes, this is the same method I use with a PowerBook 5300 (and other models). PC Card adapters for CompactFlash can be found for approx. 10 EUR/USD. Also perfect for file transfers on a PC-formatted CF card from PCs and modern Macs. For downloads, keep the MacBinary (.bin) or BinHex (.hqx)...

You would have to use Mac OS Standard (HFS) on a Mac running anything earlier than Mac OS 8.1. The Mac OS Standard format specifications can be found in the following article: web.archive.org/web/20030201224108/http://docs.info.apple.com/article.html?artnum=8647 The "PPC G4", which exact Mac...

The easiest way is to use a PC Card adapter for CompactFlash, or a similar (5-in-1 etc.) adapter including SD, in one of the PC Card (PCMCIA) slots of the PB 190. A properly formatted flash card with a valid system folder should even be bootable...

The video card appears to be identical, at least according to the PB 5300 note (originally at developer.apple.com/documentation/Hardware/Developer_Notes/Macintosh_CPUs-PPC_Portable/PowerBook_5300.pdf ). You may have to use archive.org and look for a very early result. The video card in...

Details about signals, monitor sense codes, et cetera at the optional video card could be found in the PB 190 developer note (developer.apple.com/documentation/Hardware/Developer_Notes/Macintosh_CPUs-68K_Portable/PowerBook_190.pdf - an archive search may be needed).

May not necessarily help in this case, but there was an optional video-out upgrade card for the PowerBook 190, intended for the connection of an external monitor. See, for example, pp 60-63 in download.info.apple.com/Apple_Support_Area/Manuals/powerbooks/0306899APWRBK190UG.PDF . One idea could...

A line simulator can sometimes be as simple as a 9 V battery in series with a 330 ohm resistor. A ring signal generator of some kind would be useful if one wants automatic answering at the receiving end (for example, a fax machine). Also, an AirPort Extreme base station A1034 with a built-in...

As has been indicated above, you cannot boot a Macintosh Portable from a CD. You would need, for example, a bootable floppy with CD-ROM software. This could be a copy of an appropriate disk tools floppy, or a Network Access Disk 7.5, with an added CD-ROM extension (compatible with the AppleCD...

Should of course read: LaPorta mentioned the Dead Mac Scrolls by Larry Pina. On page 97 in Pina's book (1992, ISBN 0-940235-25-0),

LaPorta mentioned the Dead Mac Scrolls by Larry Pina. On page 97 in my book (1992, ISBN 0-940235-25-0), replacing an 8048 (40-pin DIP, MPU 8-bit) chip located under the spacebar is said to be the solution for a non-working M0110A (Mac Plus) keyboard if a telephone cable has been used. A...

It depends on the operating system version. For example, System 7.0.1 and 7.1 would have an Apple File Exchange utility on one of the system floppies (Tidbits). Special 7.1 versions and System 7.5 have a PC Exchange control panel.

You could also have a look at Mt. Everything 1.1.1 and its documentation . However, at this point, everything would be experimental, and you run the risk of losing all information.

... and this works with the PowerBook 500 series, too. You can use a standard 3.5 mm stereo miniplug in the Sound output port (that is, the one with a speaker icon, next to the ADB port),

Is this System 7.5 (with a system enabler), or perhaps 7.5.3/7.5.5? Have you tried only classic networking (the MacTCP control panel), or (if applicable) Open Transport (TCP/IP)? With the 7100/80 (and an AAUI to RJ-45 transceiver) wired to one of the LAN ports of your router, it should not be...

According to Larry Pina's book Mac Classic & SE Repair and Upgrade Secrets (ISBN 1-56609-022-9), 1993, page 162, good results are 4.85 to 5.15 (+5 V), 11.9 to 12.80 (+12 V) and -13.00 to -11.30 (-12 V). So, especially the +6.8 V reading is very high. You should try to find the cause for this...

Hello, That does not appear to be possible, since you can start the computer, and something can be seen on the display. Normally, you should be able to read approximately +5 V, +12 V and -12 V via the DB-19 floppy drive port. Have you checked that the multimeter is connected to the correct...
