Re: An idea!
开云体育I attached a picture (not sure if the forum software allows it, but let’s give it a shot). I think there was a thread on this a while ago, but basically it’s two parts. ? First, a 2000mAH LiPo battery and power/charger module and second, a Bluetooth BLE module. The power module (Adafruit PowerBoost 1000C) has a charger input (with voltage pass-through so you can use the device when charging), a JST battery connector, power switch and power output pins (in the form of a USB A footprint; no jack installed). 5V power from the power board connects to an Adafruit BlueFruit BLE module (used for Arduino projects I suspect). This module has standard serial RX/TX CTS/RTS pins. Power and serial signals are then wired to a 0.1” 1x6 Molex-style connector which then connects to header P1 on the front panel board. All of these are mounted in an insulated Altoids tin which can sit in the lid of the tin holding the Z80MC. ? I got tired of having a serial cable dangling on my desk so this makes it way easier to use. ? Rich ? -- Rich Cini ? ?

Re: An idea!
Pretty cool, Scott. A few years before you did this, I built (from RE) the COSMAC Elf computer. I didn't have friends who'd give me parts and tools, so I bought mine. I was a bit older, and already employed by the USAF as a photographer. I also had way to many other hobbies. This was late in 1976 or early 1977, or maybe as late as early 1978. Radio Shack had the best price I could find at the time, I believe it was $15 for the wire wrap tool, and $25 for a roll of blue wire. That was quite a chunk of my pay as an A1C in the USAF at the time, so only the one color. The Elf only had 256 bytes of ram, and no rom. I got it wired up, while waiting for enough money to buy the ram, which at that time was $300 for the 8 chips needed. That was most of my monthly salary. Then there was a substantial price drop, down to $100 for the necessary chips. Got them, installed them, and discovered a wiring error that let the magic smoke out of the new ram chips. My friend Jim, who was also interested in computers and had a camera repair shop in Ft. Walton Beach, traded some of his spare camera repair tools for the fried board, and soon thereafter my wife bought me a TRS80 Model 1, Level 1, 4K machine. I made some upgrades on it, over the years, but never again built a computer from scratch. I did do some programming, for a few more years, but eventually became more of an appliance user. I've "built" several PC's in the past couple of decades, but buying parts that plug in, and maybe have a screw or two to hold them in place is not the same thing. I've been out of work for several weeks for medical issues, should be going back next week, I hope. Once I have some more income, I am seriously considering building one of Lee's Membership Card CPM machines. That is the last OS I did any serious programming in. The Z89 I was using CP/M (and HDOS) on was a kit built by my FIL, not me. I've not built anything except the odd PC now and again in at least 30 years. Reading your blog reminded me again of some of the fun I've been missing. Bill in OKC William R. Meyers, MSgt, USAF(Ret.)

I'm not sure where it ever went to. In my late teen years, I was given an INS8073 sample, which was the successor to the SC/MP (INS8060). The INS8073 had 2.5K of mask ROM with NIBL (NATIONAL Industrial BASIC Language) built in. I designed a whole computer around it, software and all. It was housed in a COMPUTER PRODUCTS I/O chassis and used multiple add-in boards that plugged into the back-plane. I acquired a dot-matrix printer that Larry from THE LITTLE COMPUTER STORE (S. Florida) retired and let me have for $100. I took it to college with me and wrote a word processor using the tiny BASIC. I recently pulled the main board out of storage, which is all I kept from the whole computer. Since there is little to no information on "the net" for the INS8073, I decided to document the project and posted a blog on it. You may be interested.? Peace and blessings. |

Re: An idea!
开云体育Oh great.? Look forward to that PCB board! I played with the 6800 a bit, after cutting my teeth on the SC/MP. Best Regards Paul Sent from Samsung tablet. |
