Still can't find any slider caps. Surely someone has some kicking around...

Wife says time to sell, so it'll be going up for sale this week after I shoot some more pics.
I'll check all this out when it gets hereMr. Black wrote:The way you can find out the year it was produced,when powering up hold buttons 1,2, it will display the month, day, year, mine is 626779, 05-29-85 is what my unit displays, which if i am reading correctly is a little later than your's.I believe the preset names on the membrane buttons where added to later models,also the early one's had a different key action a little clanky they switched to the JX10 keybed later on.Hold down button 4 while powering up it will read "Thank's Eric and Dan" Eric Persing, the programmer's for the JX8p.
Mine (well, Jim's now) displays 5-30-85. This is a firmware build/revision date, not the date the synth was manufactured. There's a thread on here describing how to compute manufacture date based on serial # for vintage Rolands, and I got a 1/86 build date from that. Yours (serial # starting with 62) is also a 1/86 build. Does yours have the presets printed on the buttons?Mr. Black wrote:The way you can find out the year it was produced,when powering up hold buttons 1,2, it will display the month, day, year, mine is 626779, 05-29-85 is what my unit displays, which if i am reading correctly is a little later than your's.I believe the preset names on the membrane buttons where added to later models,also the early one's had a different key action a little clanky they switched to the JX10 keybed later on.Hold down button 4 while powering up it will read "Thank's Eric and Dan" Eric Persing, the programmer's for the JX8p.
Nice input!. I will check mine and let you know (Sorry by the offtopic but is an useful JX8P info).Mr. Black wrote:The way you can find out the year it was produced,when powering up hold buttons 1,2, it will display the month, day, year, mine is 626779, 05-29-85 is what my unit displays, which if i am reading correctly is a little later than your's.I believe the preset names on the membrane buttons where added to later models,also the early one's had a different key action a little clanky they switched to the JX10 keybed later on.Hold down button 4 while powering up it will read "Thank's Eric and Dan" Eric Persing, the programmer's for the JX8p.
That synth rolled off the assembly line in July 1985. Shortly after I graduated from high school.DX wrote:* About the serial number /Year of manufacture / membrane names question:
Mine is a serial # 569XXX and test shows 30-MAY-85. And it has the voice names printed on the membrane buttons.
