Brendens Microbee AI Premium Plus Games disks

Sun, 08 Nov 2026 10:29:10 +1100

Thanks to Brenden for making all these games available to run on the Microbee Premium Plus. All were converted from other Z80 computers, such as ZX Spectrum, MZ-700 and VZ-300, with the help of AI. The disks are all auto booting to either the Menu or to the Game.

They all run on the Microbee Premium Plus ONLY as the extra main memory and PCG memory are needed. All run using ubee512 emulator but you need to include --model=p1024k, such as

ubee512.exe --model=p1024k -a brendens_games_01_ds80.dsk

Most, or all, have Mono or Colour modes and use the Premium Arrow keys or the Joystick for movement control. There is a *.TXT file file for each of the games on the disk. Use TRANSFER to read them for further information.

The games on Disk 1 are -

Elite - Converted from the ZX Spectrum
EUGEA - Converted from the Sharp MZ-700 and should run on a normal Premium 128k also.
HOH - Head over Heels converted from the ZX Spectrum.
Space Harrier - From a OH!X Magazine type-in for the Sharp MZ-700
ST-2 - Converted from the Sharp MZ-700
StarQuake - Converted from the ZX Spectrum
Asteroids 2- Written by Brenden also originally for the VZ-300
Empires: The Living World

The Lantern Deep is on a disk by itself because of its size. An original dungeon adventure. Beneath the old town lie the halls of the Vaunar, who kept a great Lantern burning at the Heart of the Deep to hold back the Unlight. The Lantern has gone out. You carry the last flame down to rekindle it. Explore five regions and twenty hand-built rooms.

uB-Type is also on its own disk. Its not a Typing Tutor but a horizontally scrolling shoot-'em-up game. Was originally for the VZ-300.

Microbee Solar System

Fri, 06 Nov 2026 18:44:15 +1100

Hi Microbee people,

I think it was Graham72 who shared a galaxy program earlier.

You inspired me to start my own project and I have working on this for months now. I think its ready to share. So I am now presenting my Solar System Demo.

I have intended for this to appear like it was written in the 1980's. I did have help from a couple of AI to get this working.

Here it is.

Hi all. I am Oliver Bennett . I have 5 Microbees in various states of unworking. One of these days....

Banks

Tue, 03 Nov 2026 11:18:46 +1100

Hi all,
On the Premium Plus (1024K), I'd like to confirm how port 50h selects the 32 lower-memory banks of 32K, with ROMs off (bit 2 = 1).

Bits 0–1 are clearly bank bits 0–1 (with bit 1 inverted when ROMs are off). For the other three bank bits I've found two different readings:

Bank bit

2 port 50h bit 5 port 50h bit 6
3 port 50h bit 6 port 50h bit 7
4 port 50h bit 7 port 50h bit 5

Thanks g

Microbee's Honeysoft Disk collection

Sun, 01 Nov 2026 13:19:06 +1100

Honeysoft was the publishing division of Microbee and they not only produced all the manuals but also some floppy disks in both 5.25" and 3.5" format. These were incompatible with CP/M and were copy protected but ubeedisk can copy and write these disks. There appears to have been 4 different types of the disks produced over time.

T1 = Monochrome text & Black background
T2 = Colour text & Black background
T3 = Colour text & coloured background
T4 = Multicoloured text & Black background

types.jpg (Size: 225.43 KB / Downloads: 39)

I suspect the T2 and T3 are same type. They all work on a 56k, CIAB or 128k. Only the latest T4 will work on the 256tc. The images themselves can be written to either a 5.25" or 3.5" disk using ubeedisk as all are 40track single sided images. There is one that is 80tr, learning_can_be_fun_words&numbers and only found on a 3.5" disk and T4.

The latest version of each, mostly T4 are already available in the repository in the Games or Education folder but thought it wise to present all the different types found over the last decade or so and not lost. I'm sure the collection is far from complete so if anyone has any other versions/types not included here, please let us know.

So in the MbeeTech Repository in the new Microbee/Software/System_Disks/Honeysoft folder we placed these 73 disk images

Black waves, soft hair and infrared triangles

Fri, 30 Oct 2026 18:51:32 +1100

Memories are made of this. Research by theoretical physicists Sabrina Pasterski and Andrew Strominger examines how gravitational waves leave permanent imprints on spacetime.

When cataclysmic cosmic events occur, such as colliding black holes or exploding stars, they radiate gravitational waves that carry away energy and angular momentum. These waves don’t just pass by: they leave space permanently changed. A ring of free-floating masses stays stretched after the wave has gone (the displacement memory effect). Pasterski, Strominger and Alexander Zhiboedov discovered a second effect, spin memory: a passing wave causes a permanent relative time delay for light travelling in opposite directions around a loop.

These memory effects form one corner of the “infrared triangle”, which shows that three separate ideas are the same physics seen three ways: the memory effects, hidden symmetries of spacetime far from any source (supertranslations and superrotations), and “soft theorems” describing very low-energy gravitons and photons. Strominger, Stephen Hawking and Malcolm Perry used these ideas to propose that black holes carry “soft hair”: information recorded on the event horizon when zero-energy particles fall in. They suggested it as a possible route toward resolving the famous black hole information paradox, though whether it can do so is still debated.

The attached program for cp/m microbees shows the first part: the displacement memory produced by supertranslations, and the spin memory produced by superrotations. It doesn’t show soft hair. Soft hair isn’t light or motion that could be drawn, even exaggerated, but a change in the black hole horizon’s properties, so there’s nothing to animate. The display is hugely exaggerated: a real displacement memory is far smaller than an atom over the size of the Earth, and a real spin memory delay is far too small to measure with today’s detectors.

Contiki OS / ZS DOS / MICROBEE MULTI-BOOT

Thu, 29 Oct 2026 20:07:06 +1100

I asked Claude what OS it would like to build for Microbee. At first it looked at SymbOS but stated memory issues.

Then it told me about the NEC 6001 microcomputer from Japan

  nec6001.jpg (Size: 7.56 KB / Downloads: 35)
and the Contiki OS port which features a process list, command shell, calculator, text editor, and a RAM filesystem as well as internet connectivity, telnet, email etc.

I said build away and it did. So now I have working internet @ 9600. An email client is a definite possibility if I lose the calculator and text editor.

As Someone has oft mentioned, the Microbee is a true chameleon.

Collapse OS

Thu, 29 Oct 2026 11:33:34 +1100

After my FUZIX experiment, I decided to go to the other end of the OS spectrum.

Collapse OS is a minimalist, open-source operating system engineered by Virgil Dupras to survive a global societal or industrial collapse. Built on the Forth programming language, it runs entirely on salvaged, low-power 8-bit processors like the ubiquitous Z80. Users can deploy Collapse OS to program scavenged microcontrollers, automate basic machinery, and manage local text files or radio communications without modern infrastructure.

So attached a tiny OS. Boot using Vibedrone Queen builds. A ubee512 version is in the works allowing disk saves and an Editor.

A curiosity that may prove useful.

This Microbee build has about 225 words. In Forth, every routine is a “word”, and you can define your own with :

Marrying Coreboards and Baseboards

Tue, 27 Oct 2026 23:30:01 +1100

Are there any combinations of base / core boards that don't work together -

If I dropped a 128k coreboard onto a 32k communicator's baseboard would I expect it to still work?

In the 80's we dropped our bee's off at the store to get upgraded and it all happened behind the scenes - was it just that simple?

Fuzix for Microbee on UBEE512

Sat, 24 Oct 2026 23:46:42 +1100

Knowing that emulation is all good and proper for those of us who have no access to bare metal, I took some sneaky shortcuts with VibeDroneQueen to get FUSIX booting.

BUT a real machine needs to be able to boot the image via hardware. So towards that end I have got the OS booting on UBEE512. The ubee512 screenshots are all simultaneous, using CTRL 1 thru CTRL 4 to show each TTY in operation.

I am not sure if the HD18 ROM can be used in real 512K machines, but if another ROM is needed then I can adapt the boot code to suit.

Adventures of Robbo

Sat, 24 Oct 2026 20:56:11 +1100

Here's a port of an old PC DOS game called Adventures of Robbo. It's pretty close to the original with all 60 levels. Configured to use Premium arrow keys with a Joystick option. Tested on a Freemium, Vibedrone and UBEE512 and works great.

i've added robbo06 which addresses the B: drive loading problem. Thanks Ubee.

Happy 7th Birthday to the Forum & Repository

Sat, 24 Oct 2026 12:10:20 +1100

We have survived yet another busy year, so happy 7th birthday to the forum and file repository. A BIG thanks to all those that have contributed to the forum and to the repository throughout the year, without your help none of this will survive. Your continued support is much appreciated.

In the past 12 months we have been busy and there has been many additions to the repository as well as a few of files updated and replaced with better quality scans, complete docs that had missing pages or software to later versions or to working versions.

AppliedTech-Pre-bee had 2 additional files
Documentation had .......180 additional files plus
Software had ................119 additional files plus 1 updated
Public had .................... 8 additional files
Vintage had ..................147 additional files plus 9 updated

So that's a total of 456 additional files added to the repository and 10 files updated in the last 12 months. These numbers are higher than last years (about a 2.5 times) however new material is getting much harder to find. This now makes a file total of the Repository to be just about 13,500 files all up, wow!
A big thanks to everyone that has contributed, bee it small or large, to help with both the forum and repository grow for the help to all our members and for the future. Lets see if this can be repeated in the next 12 months, though it is getting harder to find new material.

While the forum is mostly Microbee orientated, we do support all Australian Made and Produced Vintage computers plus 2 other imports that were well supported here in Australia, being the Exidy Sorcerer and Dick Smiths System 80. We are continually looking for new material to archive for the future, so if anyone can help with anything Microbee or any other Australian Vintage computer, bee it small or large, that would be greatly appreciated. We can image disks, scan docs, convert images to pdfs, dump tapes, read ROMS, etc for you if you cannot, just ask.

Happy 7th Birthday and thanks to everyone for their continued support.

DSE Cassette Tape Labels and others for the System-80

Sat, 24 Oct 2026 11:23:32 +1100

Thanks to GeorgeK for providing scans of these System-80 tape labels. Unfortunately the tapes have been lost over time.

The Instructions sheets for both Depth Trap and Scurve Invaders were also supplied and are included in the zip for both. Scurve Invaders is now complete and replaces the current version in the repository. The Space Invaders label is slightly different to the one currently in the Repository so is added as Type 2.

So in the MbeeTech Repository in the Vintage/System-80/Documentation/Pictures/Tapes folder we placed

dse_death_trap.jpg <--------- both in the one zip file
death_trap_instructions.pdf /
dse_scurve_invaders.jpg <--------- both in the one zip file
scurve_invaders_instructions.pdf /
