Here are a couple of scans of a press release folder that Sony released regarding the SMC-70. I have color scans of the marketing material here: http://zzxio.com/wp-content/uploads/2024/03/Press-release-documents.zip (it's too big to post here).

I'm looking for assistance identifying a 16 bit ISA board (and potentially a manual). The box says 81/261 9020294 Cumulus Processor Board 92163, while the board itself says Cumulus Corp ISA 486 Bard P/N 8020289. Does anyone know anything about it?

This is probably like asking for a unicorn that grants wishes, but does anyone by chance have a copy of CP/M-86 for the Sony SMC-70 Supercharger?

I picked up a 16 bit Max Logic (Cirrus Logic controller) MDA/CGA/EGA/VGA video card and couldn't find any information online about the card. If anyone has more info about it that would be helpful. There was a post a decade ago about someone asking about the MX657...

I am trying to repair a 5154 monitor. A filter cap exploded (as should be expected!), and when I went into the power supply I saw that a majority of the capacitors were either bulging or had leaked. I replaced all of the caps in the power supply and a couple on the board on the bottom of the...

I was curious if anyone has any pointers in bringing a P70 power supply back to life. With the power supply disconnected from the unit I get no voltage on any of the lines going to the motherboard (that seems really strange to me). The fuse is good, and the fan twitches when the power switch...

This might be a long-shot, but I'm trying to track down a copy of Q-manager (SMW-7076) for the Sony SMC-70 Videotizer (SMI-7050). Are there any SMC-70 users who might have a copy?

I have a docking station (PSP I (Portable Service Platform)) for an IBM PS/2 L40 SX that I’m trying to restore. When powering it on the laptop gets power, but the docking station itself doesn’t. I thought the issue was with the power supply (there are two, one for the laptop voltage, and one for...

I am looking to connect my 5155 to a Trinitron monitor. I have a converter, the Sony PC-701, that converts CGA to RGB. What I don't have is the cable (8 pin DIN to 9 pin dsub) that goes to the converter. Does anyone happen to know what the pinout of this is?

I have a docking station for an IBM PS/2 L40 SX that I’m trying to restore. When powering it on the laptop gets power, but the docking station itself doesn’t. I thought the issue was with the power supply (there are two, one for the laptop voltage, and one for the docking station), so I...

My first computer was a Sony SMC-70, and I am keeping an eye out for accessories and software for this system.

I was messing around with ImageDisk and 22disk to back up some SMC-70 floppy disks I have. I noticed that I couldn't back up a few of them. Then I slowly noticed a pattern, the disks I couldn't read were OM-D3310 disks, while the disks I could read were OM-D3320. Comparing the disks...

I dug out my SMC-70 and recorded the demo program. The SMC-70 came with an accessory that converted the RGB output to RF and composite. I connected the composite out jack to my computer to create this video. The quality isn't the best, so I might look for a better way to capture the screen...
