Eico HM-85
The Eico HM-85 shows up in the period record, but almost nothing about it has survived. The one reference is a listing in Audio-Collection (1962, p.92). It places the HM-85 among tape machines, next to models like the 4A/N and 4A/H. The fragment suggests it ran at 11 ips, had dual inputs rated at .003 V and 1 V peak, and offered output to a speaker or 2 1/2 watts at 15 ohms. It also says the unit included amplifiers and a speaker. That is all the record shows.
Beyond that single listing, there is no documented identity, production years, original price, or set of confirmed specifications. No source says whether the HM-85 was a tape recorder, a tape playback accessory, or something else entirely.
Surviving information on this model is thin. What the record shows:
- Listed in Audio-Collection, 1962, p.92
- Appears to have been a tape machine of some kind
- Dual inputs (.003 V and 1 V peak)
- Output to speaker or 2 1/2 watts at 15 ohms
- Included amplifiers and a speaker
If you own an HM-85 or have seen one in person, the archive would welcome the details.
