"I bought the first Jolt microcomputer out the door. I saw its advertisement (in Byte?) and was just starting a project in security access control. We were doing a crash project to demonstrate reading magnetic striped ID badges for Honeywell. We needed to accept a real-time bit sequence, extract numeric data and do a simple name vs. number lookup. An ideal job for a small processor. But remember, this was 1976. Development systems cost $5,000+ and none were offered for the 6502. (Later, MOS Technology offered one and Rockwell had a very good one.) I ordered a Jolt system on a Wednesday or Thursday and was told Microcomputer Associates Inc. (Manny Lemas and Ray Holt) was awaiting the first silicon of their DeMon monitor to come by air from MOS Technology in two days, on Saturday. DeMon was a one chip Debug-Monitor containing 1K of ROM, 512 bytes of RAM, paralled IO, an ASCII serial interface and a monitor program. With the 6502 processor and a simple clock you could have a two-chip microcomputer. DeMon was later renamed Tim, Terminal Input Monitor. MAI received their first DeMon chips about 9 AM Saturday morning, plugged in one, it ran, and I picked up the first unit at noon at their office. IIRC the Jolt had an inked-in serial number 0 or 1. Over the week-end I built a teletype interface as Jolt had a voltage output while the Teletype had current loop. Either at that time or shortly later MAI expanded the line to a RAM card and an EPROM card using 2702 PROMS. The boards were about 4"x6," arranged in a vertical stack jointed by a ribbon cable. Only 5 volt power was needed. Jolt was the first 6502 one board computer but soon was followed by the MOS Technology's Kim and the later Rockwell board. Manny Lemas and Ray Holt went on to merge MAI into Synertec and did the VIM/SYM one board computers. Dorado Systems used the SYM as the basis for 650 energy control systems for the Lucky food stores in the mid 1980s. Our 6502 products went mostly to Honeywell for door access control products used world-wide. Over time we migrated our development onto PCs but the blue box, Jolt based development system was our backup for development and PROM burning."
