Vintage computer collector and maintainer of https://vintagecomputer.ca I was previously known as "MrGoodBits" on Twitter. I'll be posting various pics of mostly historical computers from my vintage computer collection.

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.

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.

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

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.

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.
