Hi list,
3 years ago, I picked up an HP 9144A QIC tape drive with HP-IB interface. It
came with three 16-track QIC tape drives. I never found the time to connect it
to my HP 9000-300 and realized that I will probably never make use of it, which
is why I'd like to give it to some other collector

What about the analogy of Software Defined Radio:
Use only as much electronics as minimal necessary to get the input
signal digitized by a high speed ADC. Maybe some cheap DVB-T USB thing

36MHz does sound like the standard TV IF frequency.

The GBS-8200/8220 supports analog signals, not digital. It will directly
support the 15khz misnamed “CGA” of arcade monitors (which is the same RGB
signal the IIgs puts out), but that’s an analog signal,

Right. Me bei
Speaking of digital RGB (and RGBI) interfaces, the hardware cost of adding them
to an FPGA-based converter would be so cheap that I might as well add them to
the plan. Will an analog RGB interface for converting things like 15kHz Amiga
outputs feature-creep its way in there, too, I wonder? :)

There are probably a fair number of "TV cards" in both ISA and PCI

digital TV (and the web).

I think I should retrace the path of technology evolution. Start getting it

We spent Friday and Saturday debugging the PDP-12. We replaced a bad SN7400
driver chip and three bad bulbs in the front panel. We can now trust what
we see on the front panel for debugging information.
We tried some of the PDP-8 and LINC instructions and noticed that some of

If you want to go big-screen, some of the Presentation displays (e.g.
Mitsubishi Megaview Pro) have very wide sync ranges (e.g. Horizontal
15-90Khz) that should do very well. They're all CRTs and range up into
the 55 inch range, so you should have a strong back...
