A post of my findings on the PicDisc CP/M System for the Olivetti M10. It is pretty awesome. vintagecomputer.ca/picdisc/ #retrocomputing #vintagecomputer

Recently acquired an Olivetti M10 and PicDisc unit that turns the M10 into a CP/M computer. Had to replace the 12VDC lead acid battery and a bad diode. If anyone has any software or docs on the PicDisc system, please let me know. Still trying to figure this out. #retrocomputing #vintagecomputer

Working with my MCM/70 and MCM/900 today. The '900 is two generations newer than the '70. Both run APL but have different displays. My dual 8" disk drive for the '900 needs work (blows fuses). After a week of messing around it's away until next time I take a shot. #retrocomputer #vintagecomputer

It's not the most exciting find but I'm an Apple Lisa fan so these brochures (two of the Lisa 1) I acquired are pretty cool to me. #AppleLisa #retrocomputing #vintagecomputer

A recent acquisition of mine is a Digital Equipment DECTalk DTC07B speech synthesis card. Works really well. This is the "shorter" newer surface mount version of the original DTC07 card and works much like the very original DECTalk DTC01 in PC ISA card format. #retrocomputing #vintagecomputing

The Jupiter Ace 4000 - the rare North American version of a computer built by two ex-ZX Spectrum designers who chose Forth over BASIC. Stronger case, ROM-deselect feature, and a fascinating history. vintagecomputer.ca/jupiter-ace-4000/

Finally got my DEC VT180 Robin working fully. Power supply issues and a badly needed refurbishment on the RX180AB dual floppy drive was done. This booted up in P/M 2.2 and is running the Select Word Processing System. #retrocomputing #vintagecomputer

One project is to further explore one of the top tier computers in my collection, the Canadian MCM/70. An Intel 8008 based personal computer with built-in APL from 1974. Here I am initializing special NOS data cassettes I found and bought new lead-acid batteries. #retrocomputing #vintagecomputer

Waiting for parts for another project, I decided to give my DEC Digital VT180 Robin a look for the first time after acquiring it years ago. This is a CP/M personal computer based on the VT100 as a base. Looks like the CRT is messed up. Not an unexpected project :( #retrocomputing #vintagecomputer

Finally found an F1 floppy drive for my Royal TA Alphatronics PC! Whoo hoo! Need to get RGB colour TO vga video going. After struggling with RGBHV output, I found @leadedsolder.com's NEC PC-8801mkII RGB to VGA project. It has the same 8 pin DIN pinout! Gonna give it a shot. #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

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

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

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

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.

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

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...

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

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

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. #vintagecomputer #retrocomputer

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

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. #vintagecomputer #retrocomputer

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.

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. #AppleIII #vintagecomputing #retrocomputing

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. #vintagecomputer #retrocomputer

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. #vintagecomputer #retrocomputer #IBMPC

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! www.youtube.com/watch?v=_OHk... #vintgecomputer #retrocomputer

Working on one of my Victor 9000s just makes me happy. I love these. Got my floppy drive to work finally. Making a DOS diskette. I have a RASCSI device and would like to back up the hard drive. That's next if I can figure out this TM502 drive. #vintagecomputer #retrocomputer #victor9k

Final book jacket design for my upcoming history of Sphere computers. Looks fab. The book can as of now still be pre-ordered via the Kickstarter campaign's "late pledges." www.kickstarter.com/projects/bzo...

Had my Informer 213AE terminal out for a picture. I got this recently and it is the most interesting VT100 compatible terminal I've seen in a while. The electroluminescent (EL) display looks great. The keyboard also detaches and has a built-in modem. #vintagecomputer #retrocomputer

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. youtu.be/n5BuiTxDFHY #vintagecomputing #retrocomputing #DEC

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. #DECember #retrocomputing #vintagecomputer

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

Dropping a surprise episode! I got the chance to interview Ben Zotto, who is publishing a book I'm very excited to read! adventofcomputing.libsyn.com/episode-1695...

As a rare Sphere owner, I just backed Go Computer Now! – The Story of Sphere Computers on @kickstarter.com www.kickstarter.com/projects/bzo... Good luck @bzotto.bsky.social !

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 Volume UP when watching!

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
