Five inch type X/Y monitors. Some work, some don't.
1. SOLD Tektronix 603A storage display, not working, bad power supply? Smells like something got hot. $75
2. SOLD Tektronix 620 DC powered display. This needs +20 Volts to operate. Has a very nice display, working fine. $200
3. Tektronix 607A storage display. Working fine. AC powered. $225
4. Tektronix 605 storage display. Powers up but image is unstable. Possibly high ripple on a power supply rail? $100
5. Ailtech branded Tek display. I believe it's a 605. Does not power up, but there is no power switch. Possibly modified
to be turned on through the remote program connector? $100
6. Tektronix 604. This one is bad also, most likely the power supply. It's interesting in that it has a long persistence P7 phosphor. $125
I may keep this one for the P7 CRT.
