Hello all. I have a Grid System 2202 external 2202 drive. It has a DB-50 connector interface. Does anyone know if this is this an old SCSI interface? Or, is it a parallel interface that can plug in to the parallel port on the Grid? Thanks, -Shawn

Hello all. I have a very broken Toshiba T3200. Display badly cracked. Hard drive bad. Floppy drive bad. But, motherboard, keyboard, case, and power supply are good. C17, C18, C22, C23, and C46 in power supply have been replaced. I have another (mostly working) T3200. I am looking to trade the...

Hi all. My name is Shawn. Thanks to everyone keeping the VCF site going. :) My ultimate goal is to get my '286 Grid laptop (model 1520) to boot from Compact Flash. I have a 128 MB CF and I can't get it to boot from it. There has been many years of on again and off again testing, by many...

Hello, I am wondering if anyone has any suggestions on the best way to learn '286 assembly. I have a Grid 1520 (286 laptop). I'm the moderator over on the RuGrid laptop group over on Yahoo. mbbrutman has been a great help. But, the BIOS really needs to be decoded in order to get around some...
