I’m still enjoying messing about with the Atari Portfolio and I’ve now finally got my hands on a serial interface. Much the same in appearance as the parallel interface the unit plugs into the Portfolio’s expansion bus and carries a male DB9 connector with fortunately, unlike some other retro machines, a standard pin layout.
The RS232 parameters, baud rate, parity and so on can be set via the Atari’s Setup menu with a maximum baud rate of 9600. After plugging the interface in and initialising it I had a look through the library of Portfolio software that I have downloaded from various sources and selected a terminal emulation program called ‘Acom’ from Roudley Associates.
I connected up my trusty US Robotics modem and loaded Acom. Taking a gamble I simply entered ‘atdt’ and the phone number of my BBS, the modem duly dialed the number and I was soon logging into Nostromo without problem (apart from the screen size limitations.)
Thrilled with my success I fired off the obligatory Tweet using the same method as I’d used with my PX-8 and downloaded a couple of files before successfully connecting via Telnet to another Synchronet board.
I’m also thrilled to have acquired what I believe is a pretty rare 1Mb expansion module. From what I understand these units were available from DIP, the original creators of the Portfolio and retailed in the UK for the best part of £400, a considerable outlay. I opened the unit up and replaced the CR2032 battery before connecting it to the Portfolio. It formatted without problem and I transferred a good selection of software onto it from the Zip drive, thus far it has been working without fault.
I have seen some Portfolio’s for sale that have been converted to allow the use of standard compact flash cards in the memory card slot, this would be very cool, although battling with the restriction of the original hardware is for me part of the fun. Another possible upgrade is a backlight for the display, there’s a company selling a kit specifically for the Portfolio, however the existing screen has very good contrast, certainly in comparison to the Epson PX8 so this would have to be a luxury addition.
I took some video of the Portfolio connecting to my BBS and Tweeting via Tweety Mail, completely pointless of course but somehow very satisfying.
One of my favourite retro machines is the lovely little Atari Portfolio. Originally developed in the UK by DIP the design was licensed to Atari who released the Portfolio in 1989. The unit has an 80C88 CPU running a customised version of MS-DOS called DIP DOS 2.11. There’s 128 kB of system RAM and a 256 kB ROM which contains the operating system and some built in utilities. There’s a non-backlight monochrome LCD displaying 40 characters x 8 lines.
As is the case with many retro machines the challenge is getting software onto them. Fortunately there are a number of options available with the Portfolio including a PC-Card reader unit, compact flash adapter, parallel cable transfer and the method I’m going to discuss here, attaching a parallel port Zip Drive.
I’ve already tried the cable method which requires the Portfolio parallel interface and a suitable cable. It works fine and is a good option for the occasional transfer but gets a bit tedious when you want to move a lot of files around. I decided to take the Zip Drive route as I already have a suitable drive and disks.
The first port of call then was Klaus Peichl’s site, Klaus developed the required driver, Pofozip.sys for the Atari and is still selling it for a very reasonable 8 €. A word of caution, the driver only works with the original Zip 100 parallel port drive, a later model was released which is not compatible. Klaus will kindly waive payment until you have things working, just in case you have a later drive. You’ll also need at the very least Zipman which will partition and format the zip disk in to three 32 Mb partitions, this can also be downloaded from Klaus’s site long with a couple of other utilities.
Of course you will need a method of transfering the driver and utilites to the Portfolio before you can set up your Zip Drive, I used the parallel cable and FT.com. Once transferred you need to create a config.sys file with the Portfolio’s built in editor. Press and hold the red Atari key and tap E to bring up the editor. If you’ve copied pofozip.sys to your c: drive type device=c:\pofozip.sys into the editor then press and hold the function key and tap F1 to bring up the menu, ‘Files’ should be highlighted, press return and scroll down to ‘Save As’ and save the file as config.sys on your c: drive.
Now do a CTRL ALT DEL to reboot the Portfolio and load the driver. Ensure your Zip drive is correctly connected to the parallel interface and fire up Zipman. At this point if your driver has not successfully loaded you’ll get an error message, if everything’s fine you be presented with the Zipman menu. From here you can choose which partition to format by pressing ‘P’ to select each of the three choices. Pressing ‘T’ will cycle through the format options, the option that worked for me was 32M/FAT12. I ran into problems reading and writing to the disk from Windows 95 when I tried the other options.
Format each of your partitions and you should be ready to roll. Attach the Zip drive to your Windows 95 machine (if you need Win 95 drivers for the Zip drive you can get them from Iomega here) and transfer your Portfolio files onto the Zip drive. Windows will only see the first partition but you can copy files from there to the other partitions with the Portfolio if necessary. I found that all the software I have fitted onto the one partition anyway.
Once you’ve reconnected your Zip drive to the portfolio you should be able to access all your files from the d: drive. You can move them to the other partitions now if you want to clear the d: drive and transfer more stuff onto it from your Windows machine. If you’ve got that many files for the Portfolio do let me know.
I’ve downloaded various stuff for the Portfolio, most of it from here and am working my way through trying it all. I’m also hoping I’m to acquire a serial interface for the portfolio before too long and hook up a modem. Here is some video of me loading the game ‘Phoenix’ from the Zip Drive:-
Using my recently acquired parallel port interface for the Atari Portfolio I’ve been successfully transferring files onto the Portfolio from my Windows 95 box. Initially the process would not work, however after setting the parallel port to Auto in the PC’s BIOS, transfers worked perfectly.
I’ve been trying a number of games and utilities, one that caught my eye was Bomber by Jaraslav Janda as it’s a version of the game Blitz (which was probably a version of the original) which was the first game I bought for my Vic 20 back in 1983/84. I shot some video with my iPhone of me playing it, badly:-
Following my previous blog entry regarding printing on the Portfolio with the Epson P-40 portable thermal printer I’ve also now made a video:-
The portfolio speaks:-
I recently acquired a parallel port interface for the Atari Portfolio, it’s actually an original DIP (Distributed Information Processing) model and looks as good as new. In order to transfer files to and from the Portfolio and a PC I need a DB25 male to male straight through cable which I have on order.
In the meantime it occurred to me I could hook up my Epson P-40 portable thermal printer with a standard parallel printer cable and confirm it’s in working order.
I connected everything together, created a bit of text in the Portfolio editor and then hit a snag, I couldn’t work out how to make it print. In mitigation I don’t have a manual for the Portfolio however after a brute force attack, ie trying every combination of key presses I could think of I found the required menu.
Much to my surprise the Epson immediately burst into life and printed my text, I almost imagined it sitting there thinking, is that all you’ve got?
(Update, Video Available)
Some obligatory pictures:-
My Atari Portfolio has arrived, and what a gorgeous little thing it is indeed. I took some pictures and thought it would be interesting to include my iPad in the background. I promise I’m not neglecting my PX-8, but it’s at work as I have a Win95 box there. I will bring it home soon and take some pictures.
It might be quite amusing to do a tongue firmly in cheek, head to head review of the Portfolio versus the iPad but given that I’m supposed to be achieving something with the PX-8 (at the very least getting Filink working) it will have to wait.
The battery on the ram card (CR2016) was dead so I put in a new one and formatted the card which appears as a disk under DIP Dos. I used format a:/v (the /v switch allows you to assign a volume label after formatting.) The battery compartment sits at the top left of the card and is released by pinching the small plastic lug towards the battery tray allowing you to slide it out.
For now the Portfolio pictures.
