Recent discussions of the cost of long persistence color monitors suitable for interlaced display indicated figures like $1300. The 860428 (28 Apr 86 for those who don't sort on dates) issue of ComputerWorld, page 116, carried an announcement of the Zenith ZVM-1360, a long persistence 13" diagonal unit with a list price of $799. The claimed resolution is 640 x 480 pixels in interlaced mode. Thos Sumner (...ucbvax!ucsfcgl!ucsfcca.UCSF!thos)

In order to make it into an Amiga compatible monitor you would have to replace the simple TTL input buffers into full fledge analog amps (With 20 Mhz bandwidth) Not something for the faint of heart. Of course you could get off to a good start by picking one of these up as a "Taxan" monitor at some of the Heath retail stores. The one in San Francisco was clearing them out at $399.00. --Chuck -- - - - D I S C L A I M E R - - - {ihnp4,fortune}!dual\ All opinions expressed herein are my {qantel,idi}-> !intelca!cem own and not those of my employer, my {ucbvax,hao}!hplabs/ friends, or my avocado plant. :-}

I think the point is that long persistence units are being produced at a lower price than the previous discussion indicated. The difference for changed persistence is all in the picture tube, isn't it? Production economics being what they are the chassis for several models are probably very much alike. So getting one of these tubes into a monitor with analog amplifiers might be easy. On the other hand, the phosphors being used might have sufficient nonlinearity to be unsuitable. Do you know anything about phosphor theory? I can't claim to. Thos (...ucbvax!ucsfcgl!ucsfcca!thos)

Another thing which is not helping is the Japanese Yen. C-A spends more greenbacks to buy the same number of Yen, therefore most cheap picture tubes are not coming from Japan, YET Japan is where all the technology is for tube phosphors. And even in Japan they are hard to come by...korea, taiwan, etc, are a little behind. We are however in search of the elusive inexpensive long persistance monitor that doesn't ghost too much. All this is very subjective. Does this make any sense? Jeff Porter Commodore Engineering
