Apple II PLUS accelerated

case_s

Got an another Apple II+… but a-c-c-e-l-e-r-a-t-e-d. I got this for spare parts but it’s quite ok condition for it self. Nothing fancy otherwise, just basic II Plus, luckily with the “good” keyboard.

serial_s
Serial: A2S2-247248

board_serial_s
Board : 820-0001-07 and serial : 8014. Feels like this board have been swapped later on? Most of the IC’s on board are from 1982.

case_date_s
8-2-1982 case date.

lock_s
In previous life this Plus was in some public place… no wonder it didn’t get stolen heh-heh.

psu_switch_s
Power supply by ASTEC AA11040 that luckily had the 115/230v switch.

psu_labels_s
Added some stickers so i know it’s been switched. Just for safety.

clear_legs_s
Added some legs that happened to suit it quite well, just the color being wrong. I have correct, black coming that i’ll swap when they arrive.

 

keyboard_cleaning_s

The keyboard. All other keys worked expect the spacebar. I took it off the unit and.. nasty 80’s Cola-Cola or Sugary-Coffee was spilled all over it… that took some time to get it off there. Nasty nasty stuff.
Looked like some traces were bad but after good cleaning and measuring i was amazed they all worked, expect the Spacebar. Measured the switch and it was dead. Thought already to swap the switch that i happened to have one extra of (thanks to Eduardo!). Cleaning with lots of IPA and lots of pressing the switch made it work however. 

keyboard_testing_s
…and finally it did work again.

 accelerator_s

Got also a accelerator card with a UM6502C (4MHz) prosessor installed. Seems to be clone of Saturn Systems Accelerator II-card. This works in Apple II and II+ only. The next revision by Titan Technologies (formerly Saturn Systems) Accelerator IIe worked with as the name indicates, with the IIe as well.
