<div dir="auto"><div>My first computer in 1978 was a Heathkit H8, and upgraded to a floppy disk drive, H19 terminal, and the OS to CPM.</div><div dir="auto"><br></div><div dir="auto">My next computer in 1983 was a H151 (XT clone) running MS-DOS 1.75, 64K RAM, 4.7 MHz clock, dual floppy, CGA and Hercules Mono video, a 20MB MFM harddisk, and 2 serial and 1 parallel ports. All of it was thru-hole soldered, and the floppy controller handled 4 drives - the first harddisk was not C:, but E:. Upgrades included a 2MB AST RAM card with 8080 coprocessor so I could still run CPM - at the same time as MS-DOS 2.1 with a lot of Unix utilities (Heathkit's Developer's Toolkit), 2 3.5" floppies, a 30MB RLL harddisk (that made 4 floppies and 2 harddisks on an XT clone!), RTC, sound card with dual game ports, a Z80 chip and 8MHz replacement chips (overclocked the 8088), and a thick-wire Ethernet port.</div><div dir="auto"><br></div><div dir="auto">I also enjoyed many other Heathkit kits, like hi-fi stereo preamps and amps, their matching WWV clock and thermometer, instruments like function generators, frequency counters, TV colorburst and vectorscope, frame store synchronizer with video titler, a Ham transceiver capable of RTTY decoding (as in news wire services and NOAA airport weather feeds), a phone patch, and a separate true phone hybrid.</div><div><br></div><div data-smartmail="gmail_signature"><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div>Scott G.
