I'll be posting various pics of mostly historical computers from my vintage computer collection.

This is an Hewlett Packard HP 35 scientific calculator I got "for display". I knew it would be bad and likely not restorable but when the vinegar turns green, it might be a little too far gone. An experiment to see how the gold holds up after ultrasonic cleaning in electronics cleaner.

Both of my DEC DTC01 Voice synthesis units are working great now. As such, I put a little demo of one of them singing Jingle Bells for the holiday season and #DOScember. I am using an IBM PC AT and Telix as a terminal to run a script.

Got a couple of DECtalk DTC01 voice synthesis units recently. I would say this one was a little "dusty". I wouldn't let it in the house until I used my #Wolfbox MF200 blower on it until the battery died. That duster is awesome for stuff like this.

Started #DOScember with some old time reconfiguring an old 486 PC. Added Gotek and CF card hard drive. It has a Sound Blaster 16 but could not get my Roland SBC-55 wavetable card going yet. Had to settle for a relisten of the Monkey Island theme on a Roland LAPC-I. #retrcomputing #vintagecomputer

Looking for my Ghost disk from work many moons ago, I found these beta diskettes that I still can't talk about due to NDA. This was when beta testing was limited secret testing and feedback as opposed to todays "lets release it and call it BETA". Wish I still had my "Chicago" disks #retrocomputing

Need room for #DOScember sound card fun, so it's time I put my Hewlett Packard HP 9100 calculators away again. My 9100A always worked fine. Got a 9100B working, then it died. The other 9100B kinda worked then didn't at all. Defeated after a month+ of trying :( Maybe next time #retrocomputing

Ah, #DOScember comes again. I just recently bought a #Roland SCB-55 Wavetable board in non-working condition for a paltry sum. Looks like it's had work done so it's not likely to ever work but we'll see. I think I'll break out my MIDI/sound cards for this DOScember. #retrocomputing #MIDI

Spread the word: November 25 is #ChuckPeddleDay — celebrating the engineer behind the legendary MOS 6502 processor, the heart of so many home computers and game consoles of the 80s. 💾🕹️
If you own a machine powered by a 6502, fire it up on that day and share a photo with the hashtag #ChuckPeddleDay

Hmmm... I just saw this picture in a Craigslist ad for an IBM XT and an HP LaserJet... the original. For some reason, it never occurred to me that the line started before the HP LaserJet Series II. I've never seen an original before. #vintagecomputing #retrocomputing

This is my Total Microcomputer Model 4000 computer. Technically the last of a rare Motorola 6800 based home computer that was a pioneer in an "all-in-one" computer. Six days left on @bzotto.bsky.social Kickstarter for his book detailing Sphere Corporation here: www.kickstarter.com/projects/bzo...

After replacing an obscene amount of parts including the memory, two shorted capacitors, the LM1889 for video output and more, my Interact Model One finally works. I still get static for sound but I can live with turning the volume down for now. #vintagecomputer #retrocomputer

Got my Tecmar Mac Drive working after recapping and repairing the power supply and replacing a shorted cap on the main PCB board. Very cool serial based drive that was available BEFORE Apple's HD20 hard drive solution. #Macintosh #vintagecomputer #retrocomputing

I haven't posted a decent computer pic in a while. How about this one?
This is the Comterm Max PC clone in a wedge case. First available in 1984, these were used in schools in Quebec, Canada. From the makers of the Dynalogic (Bytec-Comterm) Hyperion. #vintagecomputing #retrocomputing

Playing the "Trivia Talker II" game by #Votrax on the #Commodore 64 with the "Votalker C-64" cartridge installed. I love the classic sound of the speech synthesis from the SC-01 chip within. #vintagecomputer #retrocomputer

Working on a Tandon computer with an MFM hard drive. I didn't realize you could terminate the drive chain by plugging in a resistor pack terminator this way. I've never seen this before. Very cool. #vintagecomputer #retrocomputer

Found a Memotech keyboard for the ZX81 that doesn't appear to be used. I'm not usually a "box" person but this is a nice one. Will have to try it out the next time Sinclair is in the "review and see if everything still works" rotation. #vintagecomputer #retrcomputer

Happy 50th anniversary to the MOS 6502! Could Microchess for the KIM-1 be the first commercially available game for the 6502? The yellow booklet of the left is version 1.0. You typed it in yourself but there was an optional cassette. Let me know your thoughts. #vintagecomputer #retrocomputer

If you've ever dealt with a swollen laptop battery, you'll love these throw pillows on Aliexpress. When I saw these, I thought they were hilarious :)

Decapped a Microsystems International Limited (MIL) MF7115 RAM chip from 1972. This was part of the chipset of the MF7114 CPU that started out as the #Intel 4005 (4004 follow up). After Intel abandoned it, MIL continued the design work. It and this RAM vanished into obscurity after 8008 came out.

Putting together some PiSCSI units. I ordered the parts and boards and when they arrived, I quickly understood what "0402" meant in terms of surface mount components. R3 and R4 are two of them. Good Lord those are small! I lost six of them just taking the plastic off the stripe.
