Tauntek Logic IC tester upgrade

In video #22 a month or two back I built a Tauntek logic IC tester. These are firmware upgradable, and while there were no new features in the latest release that I felt a burning desire to have, I thought I’d run through the process of doing the firmware upgrade so we could see how it’s done.

Making an SVI-328 disc BASIC boot disc

When I got my Spectravideo SVI-328, it came with a floppy drive but no floppy discs. A chance visit to the Spectravideo Facebook group for a different matter led me to a cassette file that I could use to create a disc BASIC boot disc (and CP/M boot disc). This video runs through the process of creating the disc BASIC disc using a SVI-CAS digital playback and recording device (the process to make a CP/M boot disc is almost identical)....

Spectravideo 80 column card - ...or not

Well, that didn’t go as planned… The “plan” was to test out the SVI-806 80 column video card.

Repairing a Sony TC-K590 tape deck

This week I’m repairing a Sony TC-K590 tape deck. I started this a few weeks back but had to wait for parts to arrive from the UK. Was difficult to cut down 3-4 hours of footage into a watchable video without it ending up all disjointed – hopefully it came up OK :-)

Tauntek Logic IC tester

This time around I’m building a Tauntek Logic IC tester, which should be useful for testing 74 series logic IC’s I reclaim from old equipment, and also some 4000 series IC’s. There are other testers out there, like the Retro Chip Tester Pro (which is good for testing RAM/ROM in particular), and in time I’ll probably acquire & build one of those too :-)

Commodore 1084S-P1 repair

This time around we’re repairing a Commodore 1084S-P1 monitor (originally made by Philips). For those wondering about the doubled up insulator on the heatsink – I checked after running the monitor for 30+ minutes and the heatsink was the same temperature as the transistor (approx 35 degrees C), so the thermal conductivity doesn’t appear to be compromised.

Vectorio part 3 – reassembly

This time around I put the Vectorio back together. There’s no real surprises here – it all bolts back together about the way you’d expect. Next time around I hope to have a working composite monitor that I can plug into it (my modern Sony LCD workshop TV doesn’t like the composite output from many retro machines).
