    Using a TI Silent 700 for it's ASCII keyboard?

    Hi Folks, I'm trying to find a 7 bit ASCII parallel keyboard to interface to my PT 3P+S board, which will allow me to build up a SOLOS Subsystem B on an S-100 system. Does anyone know if the keyboards in these systems are ASCII compatible? The relevant schematic portion of the keyboard module...

    DEC VTxxx terminals, where did they go?

    I sold mine during a move for $71 plus shipping and it was working perfectly. Now I miss that thing and realized what a workhorse of a terminal it was! There used to be a great deal of these around the Northeast where DEC was located. I wonder where all the terminals have gone?

    California Computer Systems Chassis

    Has anyone come across one? I have a set of CCS boards that I would like to couple with a chassis. From what I recall the chassis is just large enough for a board set and the drives are in an external enclosure. Thanks!

    PT Subsystem B and the VDM-1 / SOL

    This board set can be used with the VDM-1 and a parallel ASCII keyboard. It also has the option of using a RS232 terminal. If using the RS232 terminal does that limit some of the applications (on tarbell tape from my observation) that can be used with the VDM-1? I have an IMSAI 8080 with this...

The prior owner of my set appeared to use a parallel keyboard with the video board. Does anyone know where I can obtain an old mechanical keyboard that is compatible...

    I think it's snapped inside. I must have broken it with a metal driver. Yes, I should have used plastic, but whats done is done. Thanks so much

    Hi Folks, I'm bringing up an ADM-3A (which I just repaired the keyboard to) and it appears it has bad RAM. This is the upper-lower case version with 14 2102 RAMs in two banks of 8. I believe each bank reflects the odd and even lines. Does anyone know how to test this RAM either in board or...

    Hi, I recently replace the foam pads in my Kayrpo II keyboard. None of them worked and were rotted out. I purchased a few different types of open cell foam, cut it with a nichrome wire to 0.2", then used a 7/16" hole punch to punch foam pads and mylar disks from a space blanket. I put all...

    MC862P MDTL TTL chip?

    Hi, I'm trying to figure out voltage levels (to correctly create a connector) on a early mechanical keyboard. I found the keyboard uses 5V, however there is another lead being used that looks like it supplies something different on a MC862P IC. I looked at the IC's datasheet and it indicates...
