I was thinking what I could do for #Marchintosh and thanks to your post, now I have one project. See if my portrait display works. Thanks!

Very cool. I happen to be working on repairing an Otrona Attache 8:16 which sounds similar. The Attache had an 8088 add-on board for MS-DOS to extend the Z80 roots. A very interesting computer if I can get her going.

This is a picture of a Commodore 500E calculator from the early 1970s with it on a desk and it powered up showing random digits through the orange glow of the nixie tubes.

Got my #Commodore 500E calculator working after replacing one capacitor in the power supply so it would power up properly and one germanium capacitor one one of the boards so it could act like a working calculator. Here's a great video on history and workings here: www.youtube.com/watch?v=pSnO...

This is a picture of a Commodore PET 8296-D computer. It's one o the latest models of the Commodore PET line. In the background is an original Commodore PET poster. A simple black poster with a PET computer in the middle and the words, "PET UNLEASH ONE TODAY".

I was able to switch my #Commodore PET 8296-D from it's normal 80 column format to 40 columns to play my favourite PET game, Miner. Loved playing that in school back in the day. This model has dual disk drives built in and is a 240V model I converted to 120V. #vintagecomputer #retrocomputer

This is a picture of a small blue terminal called "The Miget" from Micon that is very small and has a glowing red 32 character single line display. It runs at 300 bits per second with 7 data bits, no parity and 1 stop bit.

Acquire a very cute Micon "The Miget" terminal initially out in 1977. This one is from 1980 and runs at 300 bps, 7 bit, no parity, 1 stop bit. #vintagecomputer #retrocomputer

This is a picture of the Commodore 900 computer that was Commodore's first attempt at a Unix-like workstation. It used the Coherent Unix work-alike operating system. This computer never made it to production.

Had my #Commodore C900 out today to try something for a friend. More testing is needed (when I get the nerve) but it might have a medium resolution RGBI/VGA port when the stock Hi-Res ECL monitor goes.

Pictured is the Heathkit ETW-3800 trainer powered on with ETC-6811 CPU module and ETC-128 memory cartridge for program storage. In addition, there is the "8-bit Microprocessor Programming" course cartridge next to it. It gets put into the memory cartridge slot. The CPU is replaceable with other CPU modules including the Intel 8085. I'd love to find one of those. Wish it had a 6502 option.

As a collector of single board computer trainers, I acquired this Heathkit ETW-3800 trainer complete with interchangeable ETC-6811 CPU module (replaceable with other CPUs), the ETC-128 memory module (program storage) and "8-bit Microprocessor Programming course cart. #vintagecomputer #retrocomputer

This picture has an IXO TC200 mini portable terminal with Digital branding connected to and RS232 add-on speaking to a PC with TerraTerm running. It has "Hello world!" on both screens as it was typed on the PC and transmitted to the IXO terminal.

Got an IXO TC200 mini portable terminal working at a blazing 300bps. This one is branded with the "Digital" brand. I had to buy an expired Polaroid 600 Instant film pack for the battery. The RS232 adapter has it's own power.

In this picture are two different Commodore typewriters. Typewriter on left is an early Commodore grey model full-sized typewriter with original Commodore logo on it. The second typewriter is a portable blue model with later Commodore logo. They are both on a Commodore typewriter metal grey stand with folding side arms. This has the latest "chicken lips" logo on it.

As a #Commodore computer collector, I veer off into non-computing items occasionally. Finally got one of those "little blue" typewriters (right). It's next to an even older Commodore typewriter (left) and both are sitting on a Commodore typerwriter table/stand. Each with different Commodore logo.

This is a picture of the contents of the Apple III Business BASIC package. It came with a single Apple Business BASIC diskette and a blank diskette for backup purposes.

Microsoft BASIC came in the Apple Softcard III package but there was also an Apple III Business BASIC package. It is shown here with the single diskette that came with it.

This is a picture of some of the contents of the Apple Softcard III System box which has the two software diskettes in it. These "Apple Softcard III CP/M Master Diskette" and "Apple Softward III Utilities Diskette". The packing list is also shown noting that these two diskettes are the only ones that come with the package.

I should probably just post the random pics I take on occasion. This one was to answer the question of where Microsoft BASIC is for the Apple III. Happens to be on the Softcard III CP/M Master diskette.

Did you see this board that the same seller sold earlier? Might be related to this. Another loose Seequa board sold a few months ago. www.ebay.com/itm/13566676...

Love the Chameleon. Still don't have one though. I did see this board on eBay but assumed it was a Chameleon board. I don't think I've come across anything else from Seequa. Very cool but if it was fully populated, I might have went for it myself.

At least you got bubble wrap. I always show this picture noting bad "packing". This went from USA to Canada via USPS and Canada Post. If you guessed it is an Osborne 1 with a single layer of paper and tape as packing material, you would be correct. Made it without a scratch, though.

In terms of the picture above, the two big 84 pin chips on the left are not installed in the sockets. I will install them once I've installed most components and ran the board through an ultrasonic cleaner.

Hard part is done. I did have the PLCC 84 sockets. I'll put on the old CPU and make sure that once I put everything on, it will work. I could always look into an upgrade or just making another with the 486 upgrade at some point in the future. I do have extra boards, if I can find the parts.

I've put PLCC sockets on Amiga's before that had bad sockets. I may have them on hand. It will depend on how clean I can get the ICs. I, personally, like them and will replace the CPU with one I can put in a PLCC socket. I might do the 486 upgrade. My main concern is the two ICs with the legs.

I don't know if my Atten is high-end but it's pretty good. I've done a minor amount of surface mount. It's the ICs with the flat pins that bug me. They are off. Now, if they go back on straight is a whole other matter. I was very careful.

I'm going to give this a shot. Transplanting all of the components from an #Amiga A2386SX bridgeboard that had severe battery damage that I could not repair to a remake of the A2386SX board. The large square "million leg" ICs have me worried but worth a shot.

Slight correction. The Olivetti M20 is based on the Zilog Z8000 chip. Now back to the cat pics...

Congrats. She's a beauty.

This is a picture of an IBM PC Convertible computer, model 5140 with optional backlight. It is running IBM PC Convertible introductory software that IBM put out to become familiar with your new purchase.

Happy to finally have found (at a reasonable price), an IBM PC Convertible model 5140 computer. I had the normal non-backlit display but this one has the backlight. Yes, it's not great but it was perfectly fine for the era.

This is. The Comet-9 radio by our beloved Commodore.

This rare BeBox still works! YouTube video by PCWorld

Just watched this PC World video with Huxley from @retroroadshow.org showing the BeBox in action.

I need to take my BeBox out soon. This shows the original dual 67MHz PPC model. I have the later dual 133Mhz model. Nice work Huxley!

I've never tried an HD diskette in a Commodore drive. That includes the 8250.

Makes sense. I also use new diskettes in QD drives. Without degaussing DSDD diskettes, I have had problems as well.

Most of my diskettes are DSDD. I do have DSQD floppies but I use them on a couple of other systems I have. I've not had problems using DSDD diskettes as DSQD before so I'll go that way. Thank you.

So after trying many times to image my hard drive with a RASCSI device, I have some bad spots and the RASCSI won't get past that part.

Question:@binarydinosaurs.co.uk @devilishdesign.bsky.social Do you use double sided DOUBLE density or HIGH density diskettes on the V9K? I've heard both ways.

I'll first try with my Applesauce. I tried a Greaseweazle quite a while back and it was a rough time. I should revisit it and see if the software is better now. I might have to if I cannot make disks. I also have a Vicky to work on at some point and I don't have a boot disk for that one.

You are right. It's here: archive.org/details/Vict... There is a ton of Victor software that is new since the last time I checked. Although the last time, I was never able to make a working floppy so we'll have to see how things work out tomorrow.
