Two Wild Soviet Personal Computers of the 1980s
The Agat 4 and the Iskra 1256. The height of Soviet-styled, Sci-Fi inspired personal computers.

I absolutely love the computers of the old Soviet Union.

Sure, I never had one: I never lived in the Soviet Union… and I don’t speak a single drop of Russian.

Just the same, there’s something fascinating and wild about the computer industry of that particular place and time.

The Soviet-styled, Sci-Fi inspired cases. The (often) knock-off copies of hardware and (also often) stolen ROMs and software. The history, technology, and aesthetics are downright whimsical.

Presented here are two of my absolute favorites: The Iskra 1256 and the Agat 4.

Special thanks to the Soviet Digital Electronics Museum for providing images for so many (often difficult to track down) Soviet-era computers.

Iskra-1256 (1979)

While the Iskra 1256 was technically created in 1979… it didn’t really see production until 1980. So it qualifies as a 1980s computer, in my book.

First off: Just look at that keyboard. It has a distinct Soviet Sci-fi look to it, which is pretty darn cool.

Also fascinating is the internal design. It used a series of (mostly removable) boards aligned in vertical panels — and was powered by a 16 bit CPU clocking in at 3 MHz. The base RAM was 4 KB, expandable to 64 KB. Not too shabby for the early 1980s!

Also interesting: It shipped with a BASIC-like programming language. Essentially it was similar (in some respects) to Tiny BASIC… only, you know, in Russian. Here’s an example:

While I have been unable to discern exactly which processor the Iskra 1256 used, a reasonable guess would be something akin to the Texas Instruments TMS9900 — a 16bit CPU, released in 1976, that was also used in the TI-99/4A… which clocks in at the exact same speed.

Whether it is the same CPU, a Soviet clone, or some other (similar) CPU remains unclear.

One other interesting design choice that I quite like: A built-in cassette reader for loading and saving data… right on the front of the main unit. So many personal computers of this era opted to use external cassette decks — often connected to a dedicated “datasette” port. It’s rare that you find a cassette reader directly built in.

This PC was in regular usage throughout the 1980s. In later years multiple languages were ported to the machine — including a true BASIC, Fortran, and Algol.

It was, truly, one heck of a machine.

And it had a cost to match.

14,200 Rubles. Which means this machine had a cost of — quick math on the back of a napkin — over $9,000 USD in the mid 1980s. Phew. Not a cheap machine! Though it wasn’t for sale in the USA anyway… so, even if I could have afforded one, it wouldn’t have been available to me.

Agat-4 (1983)

A few years later, in 1983, an Apple II clone was produced with an absolutely wild design… the Agat 4.

Despite the extremely different appearance, the guts of the Agat 4 were incredibly close to that of an Apple II. Same MOS 6502 CPU. 64 KB of RAM. In so many ways… this is a crazy, orange, desktop form-factor, Sci-Fi looking Apple II.

It even used a slightly modified copy of the Apple II ROM.

Seriously.

Supposedly you can even find Wozniak’s name (the creator of the Apple II and Apple II ROM) inside the ROM bits for the Agat-4.

Man using an Agat-4. What software is he running? Hard to tell. But I like to imagine that it has something to do with Soviet era space ships or time travel.

The unit came in three parts:

  • A standard (but cool looking) color SECAM television.

  • The main case (which included the power supply, CPU, RAM, and a single 5 1/4” floppy drive).

  • And a detached keyboard.

SECAM is an analog TV standard that was commonly used in France, Russia, and a few parts of Europe and Africa. Similar (in many respects) to the PAL or NTSC standards. 50 Hz refresh rate (same as PAL, whereas NTSC is 60 Hz). Likewise SECAM has the same resolution as PAL. That said, where SECAM differs is that the Red and Blue colors are sent alternately… as opposed to being sent together in both NTSC and PAL signals.

There was an optional cassette port (for loading software off an external cassette player) and a printer port. Other than those, there weren’t any expansions available. RAM was locked at 64 KB. And there was no option to add a second floppy drive.

You’ll have one floppy drive and you’ll like it!

Many nicknamed this system “Yablotchko”. Which, supposedly, means “Little Apple”. A fact that the translation website I just used verified.

Despite being an obvious Apple II functionality clone (with a clearly modified Apple II ROM), the Agat 4 suffered from compatibility problems with standard Apple II software. Some applications and games would run… but many would not.

This was thanks, in large part, to the way the the engineers of the Agat 4 hacked the Apple II ROM to add in cyrillic characters, as well as minor differences in hardware design.

Later models in the Agat line would improve the Apple II compatibility… even going so far as to offering an (optional) “Apple II” compatibility card. Unfortunately, later models stopped using the awesome, orange form factor.

This Agat 7, released in 1984, had many similarities to the original Agat 4… but dropped the distinctive color.

The Soviet Union wanted to sell the Agat line in other nations. Unfortunately that didn’t go very far… as each computer was priced around $17,000 USD. Seriously. For an Apple II clone.

Making the Agat 4 one of the most expensive personal computers in world history.

Hey. The color orange ain’t cheap!

The LEGO Agat 4

Speaking of that awesome, orange design… someone created a LEGO model of an Agat 4. And it is absolutely glorious.

The futility of Ad-Blockers

Ads are filling the entirety of the Web -- websites, podcasts, YouTube videos, etc. -- at an increasing rate. Prices for those ad placements are plummeting. Consumers are desperate to use ad-blockers to make the web palatable. Google (and others) are desperate to break and block ad-blockers. All of which results in... more ads and lower pay for creators.

It's a fascinatingly annoying cycle. And there's only one viable way out of it.

After stealing nearly 60% of all Spotify revenue by spamming the site with relentlessly botted AI "musicians" and playlists that sneak their trash in with real musicians, Spotify has announced their solution.

AI slop will be labeled with AI levels. No more fake sexy women or hot men hawking AI trash that steals from real musicians. AI songs will be banned from the algorithm and major playlists built on it.

About time.

Lunduke Lifetime Discount Ends in 1 Day; Zelda, Larry, SQ, & Keen Walls Available

TL;DR: Lifetime Subscription discount ends in one day. There are currently 4 “Lifetime Walls” with space available for more names (the Oregon Trail Wall is now full).

We’ve been running a massive discount on Lunduke Journal Lifetime Subscriptions for the entire months of June and July. And it has been an absolute blast. There are now 21 (twenty-one!) retro computer walls overflowing with your names.

Pure insanity. Huge thank you to everyone who has supported The Lunduke Journal.

But the discounted price only runs through July 31st… and that moment is just about here.

When the calendar ticks over into August (just a hair over 24 hours from now), the Lunduke Journal Lifetime Subscription price goes back to normal.

  • If the calendar still says it’s July, the Lifetime price is still discounted to $125.

  • If the calendar says August… the price returns to $300.

There are, as of this exact moment, 4 retro game themed “Lifetime Walls” which still have some space for more names (check Lunduke.com for the full list):

  1. Legend of Zelda

  2. Commander Keen 4

  3. Space Quest 4

Oregon Trail, Keen, & Leisure Suit Larry Lifetime Walls

Holy frijoles! There are now 20 (twenty!) Lifetime Subscriber Walls, filled with the names of roughly one bazillion Lunduke Journal supporters.

Just amazing.

Two super quick updates:

  1. The “Desqview/X”, “NeXTSetp”, & “TRS-80 Model 100” Walls are now full! (Check them out on Lunduke.com and at the end of new shows.)

  2. There are 3 new Walls available to put your John Hancock on… and, just for kicks, these ones aren’t from Classic Operating Systems… they’re Classic Games:

    1. Oregon Trail

    2. Commander Keen 4

    3. Leisure Suit Larry

 

I don’t expect space on these Walls to last long. First come first served.

A huge thank you to all of The Lunduke Journal subscribers. Your support is deeply appreciated. You make this possible.

TRS-80 Model 100 joins The Lunduke Journal Lifetime Wall party!

Buckle up, Buttercup. Because The Lunduke Journal is about to blow your mind.

  1. The “BeOS” Wall Lifetime Subscriber Wall is now full (see all of them on Lunduke.com)!

  2. We’ve added a new “TRS-80 Model 100” Wall (because we can)! That’s the 19th Lifetime Subscriber Wall! 19!

  3. The discounted Lifetime Lunduke Journal Subscriptions are still available through to the end of this month (July).

Which means there are, as of this exact moment, 4 Walls with space available (see Lunduke.com for the full list of Walls). But these fill up wicked fast.

  1. Emacs (only a few spots left)

  2. Desqview/X (a little less than 2/3rd’s full)

  3. NeXTStep (still plenty of space)

  4. TRS-80 Model 100 (just launched)

 

Nice, right?

Worth noting: The “TRS-80 Model 100” has very limited screen resolution (240 x 64), which means only a small number of names can fit on that wall. If you want on it, I’d let me know right away.

Grab a discounted Lifetime Subscription (if you don’t already have one), then let me know (email “bryan at lunduke.com”) which Wall you’d like to see your name on.

Huge high five to everyone who has already added their name to a Wall. At the current rate, we’ll have over 20 retro computer themed walls, filled with all of your names, by the end of the month.

And, doggone it, that’s amazing.
