Last #Periphebrary post because now that it's March, it's time to cross over into #Marchintosh time!

This is the MacPhone by InterMatrix that allowed your Mac to do telephone management. Included are pages from an ad found online that describes functionality. #vintagecomputer #retrocomputer
This picture shows a #Macintosh computer set up with a MacPhone that is affixed to the side of the Mac with Velcro so it is easily removeable. This is a picture of a page of advertisement that shows the MacPhone on the side of a Macintosh computer with the phone held out to illustrate that it's a regular phone literally stuck to the side of your Mac. This is a picture of the second page of an advertisement showing the functionality in much more detail than I could post here.

One interesting computer terminal I have is an unmarked terminal with an interesting processor. While the front, bottom and rear are metal, the black shell is a made of semi-flexible plastic sheet. The processor used internally is an MOS 6505. I have never seen another like it. #periphebrary
This is a picture of an unbranded terminal. It has a metal frame with metal front facia where the keyboard and monitor are affixed. The rear is also metal but the top and sides are made of a single semi-flexible sheet of plastic. The front is white in color with a black shell covering the top and sides. #vintagecomputer #retrocomputer This is a picture of the CPU of this terminal. It is a MOS 6505 CPU, part of the 6500 line but with reduced pin count at 28 pins vs 40 and only able to access 4k of memory. This picture shows the component side of the main board of the terminal.

For #Periphebrary and the upcoming #Marchintosh, we have the Apple Djinn featured today. The Djinn is a specially made Geoport modem for the Macintosh line that also features #Minitel functionality with specially produced software for France Telecom. Watch for #Marchintosh at it begins next month.
This picture shows an Apple Djinn Geoport/Minitel modem next to a Macintosh Color Classic. You can see where it gets it's design styling when they are together. #vintagecomputer #retrocomputer This picture shows the Apple Telecom software CD with the Apple Djinn device amongst an Apple Mac. I tried to set it up and run it but the software is only in French and I did not get very far, unfortunately. This picture shows the back of the Apple Djinn. Out of the rear is an ADB cable that connects to the Macintosh. There is also a separate power supply for the Djinn for it to operate that is not shown.

#Commodore PETs had hard drives back in the day but they were not very common, likely because of the cost. For #Periphebrary, here is 17.5 megabytes of hard drive space connected to a PET. The D9060 was a 5 MB unit and the D9090 held a whopping 7.5 MB. Things were not small and quiet back then.
This picture shows a Commodore PET with three hard drive units. Two D9060 units and a D9090 unit. I was working on one of the drives at this point. #vintagecomputer #retrocomputer

Today appears to be MIDI Saturday. I took out my #Roland LAPC-I card and am playing around with SoftMPU on a Sound Blaster 16 with a Roland MT-32 and Roland SC-55 MKII. I gotta say, I think the LAPC-I card might be best #MT-32 set up/sound. #Periphebrary #vintagecomputer #retrocomputer
This picture shows a 386 computer off to the side with the monitor displaying Sierra On-lines Kings Quest I. The audio is playing through a Sound Blaster 16 paired with a Roland SC55-MkII. Also in the picture are a Roland MT-32 and a loose Roland LAPC-I ISA sound card.

Can't have a #Periphebrary without a #keyboard. Shown here are two IBM keyboards. The bottom keyboard is the iconic IBM PC Model F keyboard that was paired with the #IBMPC model 5150. The top keyboard is an industrial model used with IBM's industrial line of computers. #vintagecomputer
This picture shows two keyboards from IBM. The bottom keyboard is a beige keyboard with buckling springs known as the IBM Model F. Top keyboard is actually NOT buckling springs but Oak key switches. I guess they were more resilient for industrial applications? While it looks similar, it actually has different key caps for the Oak switches and is housed in a grey case. #retrocomputer

Today for #Periphebrary we feature the Commodore 8010 modem for the #Commodore PET. It was a rebranded Livermore Star IEEE-488 modem. It's next to Commodore's BBS software from 1982 written by Steve Punter. I believe this was the first commercial implementation of PunterNet. #vintagecomputer
This is a picture of the Commodore 8010 modem showing the acoustic cups on the left. On the right is the manual and Commodore Software floppy disk for the Commodore Bulletin Board System written by Steve Punter and distributed by Commodore. #retrocomputer

Forgot the hash tag. #Periphebrary Boy, I wish I could edit on BlueSky. :(

Today starts #Periphebrary! Vintage computer peripheral month. I know, it's not a good name but nothing goes with February.

Here is my original US Robotics Courier HST modem on bottom. I lost the power supply so I bought a newer 56K Business modem (top) and had no idea they were smaller!
Pictures are two US Robotics modems stacked up. On the top is a USR 56K Business modem and on the bottom is my original Courier HST that was "the bomb" back in early BBS days. #vintagecomputer #retrocomputer
