Very excited about my latest acquisition. A Gravis Ultrasound ACE (Audio Card Enhancer) that I don't think has ever been used. Now I need to create a 486 era PC with some interesting audio/video cards in it :)
#vintagecomputer #retrocomputing
This picture shows the Gravis Ultrasound ACE card on the left and the Gravis driver/software CD on the right. The ACE card is sitting on an ESD bag with the short audio cable meant for connection to the sound card of your choice.

Just got my MITS Altair 680. It's a little smaller than I thought. Next to the 8800, it looks tiny. Glad it works. Had to fix my LSI ADM-3A though. The contrast knob is very touchy. I'll need to replace that.
#retrocomputing #vintagecomputer
This picture depicts a Lear Siegler ADM-3A terminal with a MITS Altair 680 connected and running. The 680 is sitting on top of it's older brother, the MITS Altair 8800 for size comparison. The 680 is quite small compared to the 8800.

BEWARE Vintage Computer buyers from outside US. Your stuff will be e-wasted!

I bought an Epson PF-10 floppy drive from the US (I am in Canada) and as it travelled thru eBay Intl Shipping, it was "Liquidated" and I got a refund. Apparently a new US policy is the reason. kotaku.com/trumps-new-e...
This is tracking information informing me that my Epson PF-10 floppy drive "Did not pass Inspection" at the Ebay International Shipping hub and has been liquidated. Please see the news article link and pass this on so that at least some of this vintage computing equipment will not be e-wasted.

Recent acquisition. First ever CD-ROM drive was the Philips CM100. It had a proprietary LMSI interface. The Philips CM110 shown here is the SCSI counterpart. I believe this may be the first SCSI CD-ROM drive. Don't know is if they came out at the same time or if SCSI was later? #retrocomputing
This picture shows the Philips CM110 CD-ROM drive running. There is a dark bar you press to lift up the CD cover so you can carefully insert the CD-ROM. You click the "Run" button and it spins continuously and illuminates a "RUN" light. When you click "Run" again it stops the CD-ROM from spinning. There are no other front buttons. On the back of the Philips CM100 is two SCSI connectors and a push button ID selector switch. There is a black button on the back that I don't know what it does. Maybe a Reset button? To the right of the power socket is an On/Off pushbutton switch. There is a large dark metal heat sink that protrudes from the back of the beige plastic case. This picture shows the two halves of the unit once opened. The left side has two stacked card that differ from the CM100 that only has one card. The single card is used for the LMSI connection. These two stacked cards are used for the SCSI connection. To the right is the CD laser unit and circuitry along with the power supply. It has a large hidden from view transformer that makes the CM110 quite heavy.

I've had this NEC Trek PC-6001A computer for years but never took it out of the shipping box. I remember it having chicklet keys and the tape player but it turns out, it had the PC-6021A thermal printer. No cable though :( It's Centronics 14 pin to 36 pin. Will never find that. #retrocomputing
Pictured is an NEC PC-6001A computer with a PC-6021A thermal printer next to it both powered on. On the other side is an LCD monitor with a green screen showing the N60-BASIC loaded up and running.

Finally tracked down a Commodore VIC-1605 VicModem phone adapter used here in Canada. This came in the Viccessories package that included the 1600 VicModem and the original Commodore phone. Still on the hunt for one in a box but that is unlikely to find anymore. #retrocomputing #vintagecomputer
Pictured here is most of the contents of the Viccessories VicModem package exclusively for Canada. It includes the 1600 modem, the VIC-1605 VicModem Phone adapter and the Northern Telecom Commodore branded telephone.

Working on my Exidy Sorcerer's this week. I think they multiplied because I swear I only had two. So far 1 out of 4 is working properly. #retrocomputing #vintagecomputer

With a small collection of "luggable" computers, I just acquired a Panasonic Sr Partner with dual 360K floppy drives running MS-DOS 2.11. I think this might be the heaviest luggable I own and I do have an IBM Portable Personal computer (Model 5155) too.
This is a picture of a Panasonic Sr Partner personal computer running a Sr Partner demo. The keyboard is removeable and there is a built-in thermal printer where part of a printed document is showing on top.

Got the BeBox out for a regular run to make sure everything is still okay. Love this thing. #retrocomputing #vintagecomputer
This picture shows a dual 133Mhz Power PC powered BeBox with BeOS 5.03 running. It's connected to a VGA monitor, IBM Model F keyboard and a mouse. Multiple windows are open on screen.

Needed to make a ribbon cable for connecting a floppy drive to a Lobos Max-80 I was testing. It's a bit strange. If it does not boot up, you get a beep but absolutely no video output. This is supposed to be a TRS-80 clone. #retrocomputing #vintagecomputer.
Pictured is a Lobos Max-80 computer booting up MaxDOS Six from a random 360K floppy drive.

I've been making my own ribbon cables for a while now and once I found this "ribbon cable tester" online, I LOVE it! No more multimeter continuity testing on each pin to troubleshoot. I had the edge connector ends already so I can test floppy ribbon cables. #retrocomputing #vintagecomputer
This is a picture of a Treedix JTAG Cable Tester Board testing a floppy ribbon cable. LEDs lit up mean the wires are connected properly.

Another project I have is a Spectavision Compumate add-on for the Atari 2600. I believe it may be a PAL model and I need to convert it to NTSC. From my research, the internal piggyback ROMs might have to be changed. Right now video rolls. Might be the last time this ever worked. #retrocomputer

Dug out my two Kaypro 2000s last night. Plugged them in. The earlier vertically "narrow" screen model works fine even with long time dead batteries. The later "wide" screen model Kaypro 2000 does not work :( I needed another project. #retrocomputing #vintagecomputer
This picture shows two Kaypro 2000 portable laptop-like computers that are both black. The newer model on the left has a vertically wider screen. The original model on the right has a more narrow screen. This picture shows a screen close-up of the earlier Kaypro 2000 on and booting up. The screen contrast is terrible but it's common in screens of this era.

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
This is a picture of a black Samsonite briefcase of early 80's vintage with a PicDisc 3.5" single sided, double density disk drive attached to an Olivetti M10 computer. It is on with CP/M TRS2.2a booted up and ready.

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
This picture shows the MCM/70 computer on the left and the MCM/900 computer on the right. To the left of the MCM/70 is a box of "new old stock" data tapes that work with it. A fortunate find.

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
This picture shows a number of Apple Lisa brochures including a multi-page booklet for the Apple Lisa 1, a two page brochure in the center for the Apple Lisa 1 and several specific brochures for hardware and software for the Apple Lisa 2 including the Apple Lisa 2 System Overview, LisaTerminal, LisaProject, Lisa Profile, Pascal and LisaGraph.

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
This is a picture of the DECTalk DTC07B PC card sitting on a table. It's on the ESD bag sitting on the original DEC box. This was packaged as just the card with no other accessories.

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
This is a picture of a DEC VT180 computer system. It's essentially a VT100 terminal with additional hardware to make it a fully functional computer. There is a dual disk drive on top of the computer and a box of DEC software in a beige floppy box to the right.

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
Shown here is the MCM/70 computer from Micro Computer Machines released in 1974. This uses dual direct tape drives for storage of both data and programs AND additional virtual memory (workspace) up to the size of a data cassette (about 100KB). The batteries are for battery backup so that if there is service interruption, the batteries will allow the workspace to be saved to cassette. When power is restored, the workspace will automatically restore to when it was last shut down.

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
This is the first testing of a DEC (Digital Equipment) VT180 known as the Robin. The CRT is showing a top half squiggly line and faint garbage of the lower half of the screen.

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
This picture shows a Royal Alphatronics PC also known as the TA (Triumph Adler Alphatronics PC outside of North America). It has the beige PC in front with a composite monitor and newly found FI disk drive. It has booted up with CP/M 2.2. #vintagecomputer
