Initial Inspection
As received, the machine was in generally good condition, with some scrapes and small cracks in dark brown front panel/keyboard surround. It was missing a threaded fastener for hold-down screw in right front corner (viewed from front).
No ROM blocks were in the plug-in slots; tags inside the ROM compartment door indicate Options 271 (plotter control), 272 (extended i/o), 274 (string variables), and 276 (7094 words read-write memory) were installed. The memory label has been overwritten to indicate 16096 words of Infotek memory.
Main boards (from the front) are HP 09830-66521 ROM Basic I, Infotek 13468 Address Decoder, HP 09830-66583 T Register and one Infotek 13237 16K memory module, populated with 4116 DRAM chips.
Internal ROMs (from the front) are 11271, 11272 and a second 11272. The last two slots hold a 09830-66526 Basic II ROM and a 09830-662525 ROM buffer.
