Today, I've powered up the CPT 4200 from the early 1970s and am now trying to sort out a jammed up Selectric typewriter (I'm not a typewriter guy). I can then see if any of the tapes I got with it will print out documents. #vintagecomputing #retrocomputing

Someone recently posted on another site about their CPT 4200 and had some questions. The CPT 4200 was an early form of "word processing" system from CPT Corporation. It used a highly modified IBM Selectric typewriter as a printer and keyboard and cassettes for reading/writing text/documents.

Got my copy yesterday as well. Can't wait to dig in. #vintagecomputer #retrocomputing

Welcome to the Outbound club! Membership is limited but Outbounds are pretty cool. I have the earlier Outbound Model 125 with the IR keyboard (and option cable). Good luck with your restoration.

This is a picture of a Olivetti Programma 101 desktop computer/calculator. It is sitting on the floor so I could get a good profile picture.

Listening to Episode 178 "The Programma 101". www.youtube.com/watch?v=5lpc... I listen while working on #vintagecomputer restoration. This Olivetti P101 still needs work. Being both digital logic and mechanical moving parts they are tough to work on. Thnx @adventofcomp.bsky.social #retrocomputing

This is a picture of a Teletype model 43 ASR unit. The unit has a keyboard in front and prints it's output on paper instead of monitor. Some paper is shown. On the left is a matching Teletype Paper Tape reader/punch that allows for storage of information or programs for other computers. Both are matching as they are the same model.

Did some restoration work on this Teletype Model 43 ASR and rarer companion paper tape punch/reader. I still have one issue with the punch in that it punches one bit always but the chips internally are rare enough that it's good enough for now. Next time. #retrocomputing #vintagecomputer

This pictures shows two Macintoshes on either side with monitors and keyboards in the middle. We have the Macintosh Quadra 950 running System 7.5.5 and on the right is the Macintosh Workgroup Server 95 running A/UX 3.1.

Had to take a picture of "the boys" while they were out for #Marchintosh On the left is the Macintosh Quadra 950 running System 7.5.5 and on the right is the Macintosh Workgroup Server 95 running A/UX 3.1 #vintagecomputer #retrocomputing

I know, kinda "geeky" but I'm excited about finding this Teletype Model 43. I previously acquired the matching M43 paper tape punch/reader. This model, has the "Aux" port for the M43. Got the GNT 3601 paper punch in the deal. Like used together. Needs cleaning. #vintagecomputer #retrocomputer

I am happy to say both the BlueSCSI V1 and V2 were an issue with construction! After checking the solder joints under a microscope, I had to fix a few joints. While I didn't put these together, I probably should have checked that earlier on. Super happy I can use a BlueSCSI V1 and match the Q950.

The computer I worked on before that was a Quadra 950. Got that going on a BlueSCSI v1. Once I play with A/UX a bit on the WGS 95, I'll take the Quadra 950 apart and check if it's the actual V1 and V2 units I was trying to work with. The V1 might have been dodgy. It was my first and only V2.

Trying to set up my hard diskless Macintosh Work Group Server 95 for #Marchintosh After a day of futzing with a Blue SCSI v1 and v2, upgrading firmware, all combos of termination etc with no luck, I plugged in a ZuluSCSI RP2040 and worked first try. Glad it works but disappointed at the same time.

As I go through some Macintoshes for #Marchintosh, these Sony Mac floppy drive gears are going to be the death of me. Ordered a 12 pack off of eBay. Let's hope I can get these back together again because the clips that hold on the back plate are super brittle. #vintagecomputer #retrocomputer.

Macintosh Portrait Display number 2, not so good. It's quite dim compared to number 1. I am certain both need a recap. #2 has a quieter fan than #1. Will have to look at that too but maybe next #Marchintosh. Focus this time is recapping the fleet.

Macintosh Portrait Display number 1 is totally fine.

This is a picture of a Macintosh Quadra 700 with a Radius Precision Color Pivot displaying the Mac OS 7.1 desktop. It is in "portrait mode" which means I got the drivers working.

Got my Radius Precision Color Pivot monitor working for #Marchintosh I had to recap four Macs before I could find one that would show color. Now I have to fix 2 of the 4 Macs and go through the rest of my Macs while I'm at it. Got two Portrait displays to check too. #vintagecomputer #retrocomputer

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.
