Protext lives!

Protext screenshot (dosemu)

Oh man, Protext! For years, it was all I used: every magazine article, every essay at university (all two of them), my undergraduate dissertation (now mercifully lost to time: The Parametric Design of a Medium Specific Speed Pump Impeller, complete with spline-drawing code in HiSoft BASIC for the Amiga, is unlikely to be of value to anyone these days), letters — you name it, I used Protext for it.

I first had it on 16kB EPROM for the Amstrad CPC464; instant access with |P. I then ran it on the Amiga, snagging a cheap copy direct from the authors at a trade show. I think I had it for the PC, but I don’t really remember my DOS days too well.

The freeware version runs quite nicely under dosemu. You can even get it to print directly to PDF:

  1. In your Linux printer admin, set up a CUPS PDF printer. Anything sent to it will appear as a PDF file in the folder ~/PDF.
  2. Add the following lines to your ~/.dosemurc:
    $_lpt1 = “lpr -l -P PDF”
    $_printer_timeout = (20)
  3. In Protext, configure your printer to be a PostScript printer on LPT1:

The results come out not bad at all:

protext output as pdfProtext’s file import and export is a bit dated. You can use the CONVERT utility to create RTF, but it assumes Code page 437, so your accents won’t come out right. Adding \ansicpg437 to the end of the first line should make it read okay.

now *that’s* a user interface

Multi-resolution screen? Check. Sprite-based VU bars? Check. Oscilloscope channel overlays? Check. Mouse pointer as a little dude who jumps up and down in time to the music? Check.

Only on Amiga …

The lost art of the ramdisk

You don’t hear anything about ramdisks these days. What with intelligent OS file cacheing, we don’t really need them. Back in Amiga days, though, the RAM: drive was blisteringly fast. You’d put your small files there, and you could move them around really quickly.

Third-party ram disk drivers added features like the ability to survive a reset, and be more dynamic than C-A’s offering. The ASDG Dynamic Ram Disk was written by Perry Kivolowitz, who went on to win an Oscar for digital rendering techniques.

I just downloaded the first 1000 Fish Disks from Aminet. Back in the day, that would have cost me £3000, and would have involved serious floppy storage. As is, it took just a couple of hours.

I used to write for short-lived PD Shopper magazine. There was one flaw in the business plan; trying to sell a magazine to people who were naturally inclined to be cheap. As soon as shovelware CD-ROMs became available, PD Shopper vanished.

actually quite happy to see this

Dammit, E-UAE is fiddly to set up. I finally got hard disk images working, by doing something like this:

  1. For an 160MB image, create the blank file: dd if=/dev/zero of=blank160.hdf bs=1M count=160
  2. Add the file specification to your .uaerc, something like: hardfile2=rw,DH2:$(FILE_PATH)/Amiga/blank160.hdf,32,1,2,512,-12,
    (Yeah, linux e-uae doesn’t allow you to add in HDF images. Annoying.)
  3. I found I had to put the amiga system executable FastFileSystem in with my ROM path. Your path may vary – look at the UAE log output for something like ‘RDB: fakefilesys, trying to load ...‘, and see where you want it to go.
  4. Pop into UAE, start a CLI or Shell, and issue this command: format DRIVE DH2: NAME hd160 FFS QUICK

I’ve updated the drive images from yesterday, so you probably won’t need to format them.

amiga: blank hdf images

I’m trying to get running an Amiga again, to see if I can remember what was rocking my computer world twenty years ago. I want to run that code, swim with the Fish disks, and generally muck about with what was my life back then.

Emulation is interesting. Variants of UAE (which came with an Amiga Forever CD set I bought in 1997 or so) rule the roost. Quality is variable – on Windows, WinUAE is very comprehensive, even making grink-gronk noises as the floppy spins. On Mac, E-UAE is really not worth the bother kinda okay – it doesn’t want to emulate anything above a 68000, and falls over quite often but has decent sound. On Linux, it’s plain and stable, and I happen to have an old Thinkpad going spare I can dedicate to emulation.

I would have expected all the old disk images to be readily available for download. It seems that the current owners of the Amiga name (this week, at least) still cling on to the old IP as if it has real value. The Amiga games market (which was the market) basically collapsed with Commodore in 1994. I really wonder who is buying the PowerPC based, vastly overpriced new hardware? For now, I’m relying on good old-fashioned torrent sites for my data.

I want to emulate two machines; the A500 I had for all my cringe-worthy magazine writing running Workbench 1.3, and a fast thing maxed out with all the processors and RAM I never had, probably running 3.1. While I did have Amiga[D]os 2.04 (can’t remember if they’d dropped the D by then), it wasn’t the main focus of my interest by then.

The biggest problem I have is getting hard disk image, even blank ones. UAE is picky. Here are a couple I formatted under WinUAE, both blank.

I wonder if they’ll work under 1.3?

Update: yes, they should. I formatted them FFS under AmigaDos 1.3.
